Hi,
I can list all the roles from my EPF Composer model, I can also list all
the tasks and phases, as well as the work products, etc.
But I can't find a way to get the RoleSets. I'd like to list the RoleSets
and then get the Roles from them.
Here is an example of how I can list all the roles (and also the rolesets,
but there's apparently no way to know whether it's a roleset or a role) :
Resource resource = resourceSet.getResource(fileURI,true);
for (Iterator i = resource.getAllContents(); i.hasNext();) {
Object o = i.next();
if (o instanceof RoleDescriptorImpl) {
RoleDescriptorImpl rdi = (RoleDescriptorImpl)o;
System.out.println(" - Role : " + rdi.getPresentationName());
}
}
And by the way, I get no "RoleSetImpl" from resource.getAllContents().
I also have the same problem for Work Products and Work Product Types. I
can list the Work Products but I can't have the Work Product Types.
Thanks in advance,
Quentin

Try to avoid using Impl classes of the models. Using RoleDescriptor
should be sufficient for all your purposes.

I'm not sure how a RoleSet relates to a RoleDescriptor...

I know nothing about this model, but my guess would be that these things
are contained in different resources while the above will only give you
the direct contents of the first resource. There's probably a better
way to get to them than by brute force, but I'd have to know the model
structure to know that, and I don't. For a brute force approach, try
resourceSet.getAllContents() to visit all the resources in the resource set.

Thank you for your reply,
You said that I should avoid using Impl classes, but when I use
getAllContents(), I only get Impl classes.
And, when I have an instance of RoleDescriptorImpl for example, I can use
RoleDescriptorImpl.getRole(), to get a "Role" class. So, in any cases, I
never get the "RoleDescriptor" class.
How can I get this kind of classes ?
I tried resourceSet.getAllContents(), but I get approximatively the same
results than before, because I apparently have only one resource.
Also, I can list guidelines from phases for example, but is it possible to
get all the guidelines independantly of the components they belong to ?
(all in the same iteration)
Thank you,
Quentin

Yes, you get implementation classes of the public APIs. But that
doesn't mean you show be using those implementation classes in your
code. Similarly if you use an IFile, you'll end up with File
implementation class that you cannot use in your code because it's not
exported by the plugin.

I think you're overlooking thef act that RoleDescriptorImpl implements
the RoleDescriptor interface and that the interface is the public API
you should be using.
>

The same way you got the Impl classes, but from the Java package that
has the API rather than the Java package that contains all the
implementation classes for that API.

This seems to imply there is only one resource and it does not contain
any of the data of the type you are looking for nor does it contain
reference to other resources. Does that make sense?

It seems to me your approach of visiting the whole resource would be the
way, but given my complete lack of knowledge about the model I can only
make guesses. What kind of relationship gets you from a phrase to a
guideline and how does that relate to this RoleSet thing... You might
just try to print out every "o" you visit to get a better sense of all
the objects contained in the resource...

--> Yes it seems so, you're right.. that's why I'm really confused, because
the EPF Composer model I've been given effectively contains elements that have
been declared.
About the fact you don't know the model, I'm really sorry but the model is
"company confidential"... I'd like to quickly introduce you to it, but I
can't.
I can tell you that for example, in the "Business Development" phase,
there is a guideline associated to it, which explains some points about
marketing requirements.
But no connection with the RoleSets.. it's another problem (being able to
list the rolesets, and then the roles corresponding to them).

Somehow you managed to org.eclipse.epf.uma.impl.RoleDescriptorImpl, so
whatever you did for that, you'd do it the same way.

Well, I know the fact there seem to be multiple problems completely
confuses me, so I'm all out of helpful things to suggest.

I have cast the RoleDescriptorImpl into RoleDescriptor and I'm able to use
the interface, but it unfortunately doesn't bring any solution to my
problems.
To sum up, my different problems are:
- I can't list the "RoleSet" elements from the model (my EPFC file:
model.xmi), but I can list all the "Role" elements (and some of them are
"RoleSet" but nothing can point out that they are Role Sets...)
- I can't list the "WorkProductType" elements neither, but I can list all
the "WorkProduct" elements
- When I list the guidelines, I can't have their name (getName() or
getPresentationName() returns an empty string) although they do have names
as EPF Composer shows them.
Is it possible to access EPF Composer source code ? There would surely be
the solution to my problem in it, since it can browse my model.
Thanks in advance,
Quentin

I almost get the sense that multiple inheritance is involved. I.e., I
think you are telling me that RoleSet inherits from Role, right? It's
important to realize that Java doesn't not support multiple inheritance
of classes. So the Impl class that implements RoleSet might not inherit
from the Impl class that implements Role. After all, if it inherits
from two unrelated model classes A and B, while RoleSet will be an
instance of A and of B, RoleSetImpl will inherit from either AImpl or
BImpl, but not both. In any case, you are telling me you can list all
the Role instances but none indicated that instanceof RoleSet is true.
That seems to imply to me that none of the Role instances are RoleSets;
Java doesn't tend to lie abut such things.

This is like asking, why can I find A but I can find B? How would I know?

It sounds to my like an unresolved proxy. Does EObject.eIsProxy return
true for them? If you have unresolved proxy problems, which also
sounds like a likely issue, it's most likely caused by not using an
appropriate absolute URI to load the initial resolves. Relative URIs
within the serialization are resolved against the URI used to load the
resource (just like in .html pages in a browser). Does the .xmi contain
href="" attributes?

Most projects ship with an SDK that includes the source code. It's
certainly in CVS...

Anyway, I finally figured out why I could list roles and rolesets at the
same time, and why I was getting duplicate roles : what we get from
getAllContents() is the entire Work Breakdown Structure, as displayed in
Eclipse Process Framework. So, if we only extract the Roles, we miss the
Phases that are the fathers of roles (as in Tree meaning). And that could
be OK for our project... I thus believe it is no more a problem now.
But the problem of the work products having no name is still actual.
EObject.eIsProxy() applied on work products returns "true". Plus, I use
absolute URI, as you told me to do. The .xmi file doesn't contain any
empty link (href="").
Another problem, but maybe it's not the right place to ask for here, when
I want to use the classes I've made for reading the XMI files, from my
Eclipse plugin which is graphical, I get a NoClassDefFoundError. I've been
searching the web for a while now, without succeeding in resolving this
new problem... Seems to be a CLASSPATH environment variable problem, but
I've tried many manipulations on it, it still doesn't work :
java.lang.NoClassDefFoundError: org/eclipse/emf/ecore/resource/ResourceSet
Thanks for your help,

It sure hurts my brain when you say some Roles are RoleSets...

I wasn't trying to imply there were empty but rather to determine if
there are cross file references. What was the actual value of the URI
you used to load the initial resource as what do these href values look
like?

A common mistake is to fiddle with the classpath via the project's
properties when, for a plugin, you must edit the dependencies of the
MANIFEST.MF or the compile time problem will just come back at runtime.

I've tried to use resource.getEOBject("the URI") but I couldn't get any

In what concerns the classpath, I've already tried to modify my graphical

message "Error creating the view", because of the
java.lang.NoClassDefFoundError exception.
In the PDE (Plugin Development Environment), I can't add my library in
"Imported Packages". And when I try to add it myself directly into the

"No available bundle exports package 'com.(...).library'.

This is a relative URI, not an absolute one, so relative references
within that resource will not likely be handled correctly. It would be
good to see the actual value that you're using.

I don't know anything about uma schemes. I guess human readability
wasn't a concern...

That method uses just the fragment, i.e., "_GgH6wOn8EdyMKb-pMuCr4g". I
would imagine that even if the proxy fails to resolve (you can cast to
InternalEObject and use eProxyURI to see the URI of the proxy that's
failing to resolve) you'd still have a resource with URI
"uma://_wTuT0MmrEdyxNoaGNtevxw". If you called getErrors on that
resource, it will likely indicate why it failed to load. It sounds like
you might well need to be hooking up some special support to handle uma:
scheme, but that's an probably EPF question I can't answer...

Well, you mustn't have the dependencies right.

Concerning the path of the XMI file, I said "model.xmi", but I actualy

here.
For the proxies, I don't really understand how to use the proxy functions
on the objects, as I don't have a big knowledge about those structures.
I tried to perform some tests, like, for example :
InternalEObject p =
(InternalEObject)resource.getEObject(_GgH6wOn8EdyMKb-pMuCr4g ");
System.out.println("eProxy : " + p.eProxyURI().toString());
for (Iterator j = resource.getErrors().iterator(); j.hasNext();) {
Diagnostic d = (Diagnostic)j.next();
System.out.println("Error message : " + d.getMessage());
}
This sort of stuff... but I don't get anything interesting. I'm surely
doing wrong.
Concerning the NoClassDefFoundError exception that I get when I want to
use my library from my Eclipse plugin, I had already tried (but didn't
tell you because it seemed useless to me) to use the "Required Plug-ins",
but it's the same problem : I can't add my library in the list.
I don't know what to do now

The annoying thing is that I keep asking to see it. Given that the
references are using uma: scheme, it makes me wonder if your starting
resource should do the same.

You've already determined you have objects for which eIsProxy is
returning true. Cast that object to InternalEObject and ask for the
eProxyURI of that.

Then it sounds to my like the library on which you want to depend isn't
a plugin. When building plugins, all your dependencies must be in plugins.

It sounds like you have a lot of problems. I'm not sure how are getting

This xmi file contains uma references inside.
I've understood what you wanted me to do about eProxyURI() of the
InternalEOBject. Here is a debug output I made, from inside the loop:
- Phase : Project Specification and Project Definition
- Guideline : org.eclipse.epf.uma.impl.GuidelineImpl
- getPresentationName() :
- getName() :
- eIsProxy() : true
- getGuid() : _ou7UEha3Ed22s7Cm8XbSQw
- eProxyURI() : uma://_wTuT0MmrEdyxNoaGNtevxw#_GgH6wOn8EdyMKb-pMuCr4g
- eProxyURI of InternalEObject:
uma://_wTuT0MmrEdyxNoaGNtevxw#_GgH6wOn8EdyMKb-pMuCr4g
The two proxyURI seem to be the same... what does this mean?
--------------- Library into plugin (Using the library from the Eclise
plugin)
I've created a test plugin which only contains System.out.println stuff. I
have exported it to a .jar file. In my plugin, I did "Runtime" ->
"Classpath" -> "Add", and I added this .jar file.
And it worked fine!
Then, I tried to so the same with my library. I have exported it to a .jar
file and added it to my plugin's classpath.
--> Now, I don't get "NoClassDefFoundError: com/st/library/STXMIParser", but I
get this : "NoClassDefFoundError: org/eclipse/emf/ecore/resource/resourceSet"
(and it's my library that uses emf)
I even tried to export emf.ecore to a .jar file and to add it to the
plugin's classpath, but it doesn't solve anything.

Well, this isn't a good URI. You should be using URI.createFileURI
given this path to create a proper URI for it. With the above path,
relative references won't work correctly. In fact, I suspect you really
should be using a platform resource URI, i.e.,
platform:/resource/com.st.library/EPF6/PMM_plugin/deliverypr ocesses/PMM_lifecycle/model.xmi
(which you'd created from an IFile using
URI.createPlatformResourceURI(ifile.getFullPath().toString() ).

Not sure how you got the two, but a proxy has a URI just like this. I
would expect there to be a resource in the resource set with URI
"uma://_wTuT0MmrEdyxNoaGNtevxw". Is there such a resource in the
resource set?

EMF is already in a jar file. You should just create a dependency on
the org.eclipse.emf.ecore plugin. When we generate your model, it
should already be set up this way...

lifecycle. Thus, the guidelines can return a name.
Concerning the problem about using my library in my Eclipse plugin, I
tried to add default plugins in "Open Run Dialog", and then remove the
useless ones, and add the missing ones, according to the error log. I was
finally able to start my plugin and use the library through it.
Thank you very much for the help you provided.

Try to avoid using Impl classes of the models. Using RoleDescriptor

I know nothing about this model, but my guess would be that these things
are contained in different resources while the above will only give you
the direct contents of the first resource. There's probably a better
way to get to them than by brute force, but I'd have to know the model
structure to know that, and I don't. For a brute force approach, try
resourceSet.getAllContents() to visit all the resources in the resource set.

RoleDescriptorImpl.getRole(), to get a "Role" class. So, in any cases, I
never get the "RoleDescriptor" class.
How can I get this kind of classes ?
I tried resourceSet.getAllContents(), but I get approximatively the same
results than before, because I apparently have only one resource.
Also, I can list guidelines from phases for example, but is it possible to
get all the guidelines independantly of the components they belong to ?
(all in the same iteration)

Yes, you get implementation classes of the public APIs. But that
doesn't mean you show be using those implementation classes in your
code. Similarly if you use an IFile, you'll end up with File
implementation class that you cannot use in your code because it's not
exported by the plugin.

I think you're overlooking thef act that RoleDescriptorImpl implements
the RoleDescriptor interface and that the interface is the public API
you should be using.
>

The same way you got the Impl classes, but from the Java package that
has the API rather than the Java package that contains all the
implementation classes for that API.

This seems to imply there is only one resource and it does not contain
any of the data of the type you are looking for nor does it contain
reference to other resources. Does that make sense?

It seems to me your approach of visiting the whole resource would be the
way, but given my complete lack of knowledge about the model I can only
make guesses. What kind of relationship gets you from a phrase to a
guideline and how does that relate to this RoleSet thing... You might
just try to print out every "o" you visit to get a better sense of all
the objects contained in the resource...

the EPF Composer model I've been given effectively contains elements that have

can't.
I can tell you that for example, in the "Business Development" phase,
there is a guideline associated to it, which explains some points about
marketing requirements.
But no connection with the RoleSets.. it's another problem (being able to
list the rolesets, and then the roles corresponding to them).

Somehow you managed to org.eclipse.epf.uma.impl.RoleDescriptorImpl, so
whatever you did for that, you'd do it the same way.

I have cast the RoleDescriptorImpl into RoleDescriptor and I'm able to use

To sum up, my different problems are:
- I can't list the "RoleSet" elements from the model (my EPFC file:
model.xmi), but I can list all the "Role" elements (and some of them are
"RoleSet" but nothing can point out that they are Role Sets...)
- I can't list the "WorkProductType" elements neither, but I can list all
the "WorkProduct" elements
- When I list the guidelines, I can't have their name (getName() or
getPresentationName() returns an empty string) although they do have names
as EPF Composer shows them.
Is it possible to access EPF Composer source code ? There would surely be
the solution to my problem in it, since it can browse my model.
Thanks in advance,
Quentin

I almost get the sense that multiple inheritance is involved. I.e., I
think you are telling me that RoleSet inherits from Role, right? It's
important to realize that Java doesn't not support multiple inheritance
of classes. So the Impl class that implements RoleSet might not inherit
from the Impl class that implements Role. After all, if it inherits
from two unrelated model classes A and B, while RoleSet will be an
instance of A and of B, RoleSetImpl will inherit from either AImpl or
BImpl, but not both. In any case, you are telling me you can list all
the Role instances but none indicated that instanceof RoleSet is true.
That seems to imply to me that none of the Role instances are RoleSets;
Java doesn't tend to lie abut such things.
> - I can't list the "WorkProductType" elements neither, but I can list

This is like asking, why can I find A but I can find B? How would I know?

It sounds to my like an unresolved proxy. Does EObject.eIsProxy return
true for them? If you have unresolved proxy problems, which also
sounds like a likely issue, it's most likely caused by not using an
appropriate absolute URI to load the initial resolves. Relative URIs
within the serialization are resolved against the URI used to load the
resource (just like in .html pages in a browser). Does the .xmi contain
href="" attributes?

Most projects ship with an SDK that includes the source code. It's
certainly in CVS...

Anyway, I finally figured out why I could list roles and rolesets at the
same time, and why I was getting duplicate roles : what we get from
getAllContents() is the entire Work Breakdown Structure, as displayed in
Eclipse Process Framework. So, if we only extract the Roles, we miss the
Phases that are the fathers of roles (as in Tree meaning). And that could
be OK for our project... I thus believe it is no more a problem now.
But the problem of the work products having no name is still actual.
EObject.eIsProxy() applied on work products returns "true". Plus, I use
absolute URI, as you told me to do. The .xmi file doesn't contain any
empty link (href="").
Another problem, but maybe it's not the right place to ask for here, when
I want to use the classes I've made for reading the XMI files, from my
Eclipse plugin which is graphical, I get a NoClassDefFoundError. I've been
searching the web for a while now, without succeeding in resolving this
new problem... Seems to be a CLASSPATH environment variable problem, but
I've tried many manipulations on it, it still doesn't work :
java.lang.NoClassDefFoundError: org/eclipse/emf/ecore/resource/ResourceSet

I wasn't trying to imply there were empty but rather to determine if
there are cross file references. What was the actual value of the URI
you used to load the initial resource as what do these href values look
like?

A common mistake is to fiddle with the classpath via the project's
properties when, for a plugin, you must edit the dependencies of the
MANIFEST.MF or the compile time problem will just come back at runtime.

This is a relative URI, not an absolute one, so relative references
within that resource will not likely be handled correctly. It would be
good to see the actual value that you're using.

I don't know anything about uma schemes. I guess human readability
wasn't a concern...

That method uses just the fragment, i.e., "_GgH6wOn8EdyMKb-pMuCr4g". I
would imagine that even if the proxy fails to resolve (you can cast to
InternalEObject and use eProxyURI to see the URI of the proxy that's
failing to resolve) you'd still have a resource with URI
"uma://_wTuT0MmrEdyxNoaGNtevxw". If you called getErrors on that
resource, it will likely indicate why it failed to load. It sounds like
you might well need to be hooking up some special support to handle uma:
scheme, but that's an probably EPF question I can't answer...

Well, you mustn't have the dependencies right.

Ed, thanks again for your reply,

here.
For the proxies, I don't really understand how to use the proxy functions
on the objects, as I don't have a big knowledge about those structures.
I tried to perform some tests, like, for example :
InternalEObject p =
(InternalEObject)resource.getEObject(_GgH6wOn8EdyMKb-pMuCr4g ");
System.out.println("eProxy : " + p.eProxyURI().toString());
for (Iterator j = resource.getErrors().iterator(); j.hasNext();) {
Diagnostic d = (Diagnostic)j.next();
System.out.println("Error message : " + d.getMessage());
}
This sort of stuff... but I don't get anything interesting. I'm surely
doing wrong.
Concerning the NoClassDefFoundError exception that I get when I want to
use my library from my Eclipse plugin, I had already tried (but didn't
tell you because it seemed useless to me) to use the "Required Plug-ins",
but it's the same problem : I can't add my library in the list.
I don't know what to do now
Thank you,
Quentin

The annoying thing is that I keep asking to see it. Given that the
references are using uma: scheme, it makes me wonder if your starting
resource should do the same.

You've already determined you have objects for which eIsProxy is
returning true. Cast that object to InternalEObject and ask for the
eProxyURI of that.

Then it sounds to my like the library on which you want to depend isn't
a plugin. When building plugins, all your dependencies must be in plugins.

It sounds like you have a lot of problems. I'm not sure how are getting
past the class not found problem to see these other problems.

Ed, I have splitted the message in two problems:
--------------- Unresolved proxy (Obtaining the names of the guidelines)
The path is
" C:/myWorkspace/com.st.library/EPF6/PMM_plugin/deliveryproces ses/PMM_lifecycle/model.xmi "
This xmi file contains uma references inside.
I've understood what you wanted me to do about eProxyURI() of the
InternalEOBject. Here is a debug output I made, from inside the loop:
- Phase : Project Specification and Project Definition
- Guideline : org.eclipse.epf.uma.impl.GuidelineImpl
- getPresentationName() :
- getName() :
- eIsProxy() : true
- getGuid() : _ou7UEha3Ed22s7Cm8XbSQw
- eProxyURI() : uma://_wTuT0MmrEdyxNoaGNtevxw#_GgH6wOn8EdyMKb-pMuCr4g
- eProxyURI of InternalEObject:
uma://_wTuT0MmrEdyxNoaGNtevxw#_GgH6wOn8EdyMKb-pMuCr4g
The two proxyURI seem to be the same... what does this mean?
--------------- Library into plugin (Using the library from the Eclise
plugin)
I've created a test plugin which only contains System.out.println stuff. I
have exported it to a .jar file. In my plugin, I did "Runtime" ->
"Classpath" -> "Add", and I added this .jar file.
And it worked fine!
Then, I tried to so the same with my library. I have exported it to a .jar
file and added it to my plugin's classpath.
--> Now, I don't get "NoClassDefFoundError: com/st/library/STXMIParser", but I
get this : "NoClassDefFoundError: org/eclipse/emf/ecore/resource/resourceSet"
(and it's my library that uses emf)
I even tried to export emf.ecore to a .jar file and to add it to the
plugin's classpath, but it doesn't solve anything.

Thank you,
Quentin

I'm able to import my library with the "Import-Package" MANIFEST feature.
What I had to do was: "New" -> "Plug-in from existing JAR archives" -> and

Now, the plug-in doesn't throw any error when I put "Import-Package
com.st.library" in the MANIFEST.MF.
But at launch time, I get this error message and many other lines:

Well, this isn't a good URI. You should be using URI.createFileURI
given this path to create a proper URI for it. With the above path,
relative references won't work correctly. In fact, I suspect you really
should be using a platform resource URI, i.e.,
platform:/resource/com.st.library/EPF6/PMM_plugin/deliverypr ocesses/PMM_lifecycle/model.xmi
(which you'd created from an IFile using
URI.createPlatformResourceURI(ifile.getFullPath().toString() ).

Not sure how you got the two, but a proxy has a URI just like this. I
would expect there to be a resource in the resource set with URI
"uma://_wTuT0MmrEdyxNoaGNtevxw". Is there such a resource in the
resource set?

EMF is already in a jar file. You should just create a dependency on
the org.eclipse.emf.ecore plugin. When we generate your model, it
should already be set up this way...

If you follow one of the EMF tutorials, it will generate well formed
plugins for you...

Hi,
I finally found a solution to all the problems.
Concerning the guidances (guidelines in particular), I simply had to
obtain a resourceSet from the file plugin.xmi, and not the .xmi file of my
lifecycle. Thus, the guidelines can return a name.
Concerning the problem about using my library in my Eclipse plugin, I
tried to add default plugins in "Open Run Dialog", and then remove the
useless ones, and add the missing ones, according to the error log. I was
finally able to start my plugin and use the library through it.
Thank you very much for the help you provided.
