Hi,

since I had to convince some of the components of working together, I'll
report my steps and experiences here:
Since I did not have any official guide on how to set up everything, I
just did trial and error. So please comment, if there is any easier or
more conformant way of getting CDO-Hibernate to run...

- Downloaded Eclipse-3.4M6-modeling
- [added my favourite plugins - subversive, java2html, keepresident]
- [Create a working set for the sources of CDO etc. to keep them in one
place]
- CVS checkout of everything in
:pserver:dev.eclipse.org:/cvsroot/modeling/ > HEAD > org.eclipse.emf >
org.eclipse.emf.cdo > plugins
- CVS checkout of everything in
:pserver:dev.eclipse.org:/cvsroot/modeling/ > HEAD > org.eclipse.emf >
org.eclipse.emf.cdo > hibernate
[@Eike: there are two (conflicting) folders
org.eclipse.emf.cdo.server.hibernate one in plugins, one in hibernate]

=> I can't get hibernate to find the mysql driver class. Tried putting
mysql-connector-java-5.1.5-bin.jar in my test plugin, tried exporting
packages and using Eclipse-BuddyPolicy: dependent but no success.
=> temp solution: add mysql-connector-java-5.1.5-bin.jar to
org.eclipse.emf.cdo.server.hibernate.libraries project and add it to
that Bundle-ClassPath
=> class is now found

- next error is

Hi Stefan,
See comments below/inline marked with MT>>.

Btw, here is a small first page on the cdo-teneo-hibernate integration, it is maybe not complete and
afaics you already know most of it:
http://www.elver.org/hibernate/cdo.html

Hi Stefan,

You seem to have invested a lot of time to make it run. Most of the steps
you describe look necessary and appropriate to me.

As soon as I have more time available again I plan to create a space in
the wiki where users can persist reports about their experiences.

More comments inline...

Cheers
/Eike

Interesting, will have to look at this one. I remember that once there was
a discussion whether the incubating components (like net4j, cdo and teneo)
can become part of this distro. Will put this on my list ;-)

The one in plugins/ is obsolete since Martin joined the component as a
committer and I moved everything to the hibernate/ folder. Are both
folders non-empty in HEAD? If yes, could you please file a Bugzilla so
that I won't forget about it during the weekend?

Oh yes, this non-EPL 3rd party library stuff is really annoying!! If only
the platform itself had a mechanism to automatically provision such
dependencies ;-(

Looks ok to me.
Please notice that with the latest sources you can't register subpackages
directly anymore. They're autpomatically registered along with their top
level packages! Just in case...

Maybe we can create a fragment for the net4j.db plugin (which contains
several jdbc drivers via adapter fragments) that adds an additional
dependency on the hibernate.mapper plugin, so that the BuddyPolicy will
make the driver jars visible. Martin?

This looks like a pure Hibernate problem and I guess it's best to wait for
Martin's analysis ;-)

Happy persisting!

Hi,

today, I learned that Eclipse is always good for some extra fun.
For some reason it deleted the
<classpathentry kind="con" path="org.eclipse.pde.core.requiredPlugins"/>
from the .classpath file in all project in my workspace. It is creepy
when Eclipse does not find a single dependency anymore.
Luckily I was able to locate the problem after some time - so now I am
back and ready to proceed.

Thanks, Martin, for all your comments. As you might have guessed, most
errors I wrote were simple typos / paste errors:

Sure - this was just to report that it could cause misunderstandings.
@Eike: the folder in plugins is empty, you just get a conflict, if you
try to check out everything at once because of two folders / projects
with the same name.

Mhh .. it is not required and AFAIK there's only commons-logging.jar in
there, which has to be copied into
org.eclipse.emf.cdo.server.hibernate.libraries/lib anyway.

You're right - one could completely leave out the net4j.db.* libraries
when using Hibernate.

Hmmm ... maybe that depends on how it is used / deployed?
I get build errors that those two libraries can not be resolved.

Yes.
The problem is, as far as I can see after some debugging, a classloader
problem.

The mapping which makes problems is

[...]
<joined-subclass name="CDOFeatureImpl" table="cdo_features"
extends="CDOModelElementImpl">
<key/>
<property name="featureID" column="feature" type="int"
not-null="true" />
/ <property name="type"
type=" org.eclipse.emf.cdo.server.internal.hibernate.tuplizer.CDOTy peUserType "
not-null="false" />
/[...]

from org.eclipse.emf.cdo.server.hibernate/mappings/meta.hbm.xml

When the schema is to be created, hibernate iterated through the
mappings and comes to the mapping above.
Then we are at org.hibernate.mapping.SimpleValue.getType() (line 260)

Type result = TypeFactory.heuristicType(typeName, typeParameters);

where he tries to load the type via ReflectHelper.classForName( typeName
); and fails.

After some trial and error, I found out that adding

Eclipse-BuddyPolicy: dependent

to the MANIFEST.MF of org.eclipse.emf.cdo.server.hibernate.libraries
does the trick. With this policy set, the class is found and I can even
again delete the mysql driver class from
org.eclipse.emf.cdo.server.hibernate.libraries.

I don't know quite much about classloading in Eclipse (or OSGi,
respectivly), this is very much magical to me, but can it be, that the
missing Eclipse-BuddyPolicy in
org.eclipse.emf.cdo.server.hibernate.libraries is a bug? But then, this
may as well be the result of my "non-standard" installation (copying
jars to org.eclipse.emf.teneo.hibernate.mapper)...

Again a classloader problem, I think.
Tried a lot of alternatives of moving hibernate3.jar around and create
and delete copies of it.
No effect.

Giving up for today - maybe there's some light of wisdom coming to me
(or you?).

Anyway, have a nice weekend

MT2>> Yes I was/am actually surprised that our testcases run without this Eclipse-Buddypolicy
setting, so setting it seems a good idea.

MT2>> Eclipse-Buddypolicy dependent means that a plugin will search for classes
in the plugins which depend on it. An example, say that you have a plugin A which depends on plugins
B and C. Now assume that A passes a config file (a mapping file) to B which contains the name of a
class which is served by C. Then with Eclipse-Buddypolicy dependent in B the following will happen:
- B will try to resolve the class, but it can't as the class is not present in his own plugin
- B then asks A because A depends on B and B has Eclipse Buddypolicy dependent
- A tries to load the class but fails so it checks C
- C has the class and loads it and gives it back.

As you can see for libraries like hibernate which instantiate classes from other plugins which are
outside of the visibility of hibernate, Eclipse-buddypolicy dependent is a required feature. Note
that eclipse buddy policy dependent is not very good from a performance point of view as the class
loading process has to go through all these plugins.

MT2>> I have looked at the exception below but I can't really think why this occurs.
Do you have a cglib jar in another plugin maybe can you check that?
If you can put in a small test project and email it to me then I can try to replicate it.

You seem to have updated build.properties yesterday so now there's no

Is there a testcase using an embedded server/client (meaning: a net4j
JVM connection?). I guess a lot of the trouble is caused by this setting.
I can run the standalone hibernate server for the testcases with no
problem, but has any of you two tried testing with server and client
inside one JVM?

I started over and wiped my workspace today.
I checked out:

org.eclipse.emf.cdo
org.eclipse.emf.cdo.protocol
org.eclipse.emf.cdo.server
org.eclipse.emf.cdo.server.hibernate
org.eclipse.emf.cdo.server.hibernate.id
org.eclipse.emf.cdo.server.hibernate.libraries
org.eclipse.emf.cdo.server.hibernate.teneo
org.eclipse.emf.teneo
org.eclipse.emf.teneo.annotations
org.eclipse.emf.teneo.hibernate.mapper
org.eclipse.net4j
org.eclipse.net4j.jvm
org.eclipse.net4j.util

and added these libraries:

/org.eclipse.emf.cdo.server.hibernate.libraries/lib/asm.jar
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/cglib-2. 1.3.jar
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/commons- collections-2.1.1.jar
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/commons- logging-1.0.4.jar
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/dom4j-1. 6.1.jar
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/hibernat e3.jar
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/jta.jar

and (for now):
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/mysql-co nnector-java-5.1.5-bin.jar

I also added the mysql libraries to the runtime classpath.
To analyze class loading problems I turned on tracing of "debug/loader"
of the org.eclipse.osgi bundle.

With this configuration I get this issue:

29.04.2008 11:06:58 org.hibernate.cfg.Configuration

Ok - the problem seems to be that the
org.eclipse.emf.cdo.server.hibernate.libraries Bundle where
hibernate3.jar lives does not see org.eclipse.emf.cdo.server which
defines the mapping types.

Idea: add Eclipse-BuddyPolicy: dependent.
Thus, I also can move the mysql-driver to my test case Bundle.

This leads to:

BundleClassLoader[org.eclipse.emf.cdo.protocol_0.8.0.qualifi er].loadClass(org.hibernate.proxy.HibernateProxy)

As far as I can see, Java tries to load the class
*org.hibernate.proxy.HibernateProxy* from the bundle
*org.eclipse.emf.cdo.protocol_0.8.0.qualifier*. Why so? I think because of

net.sf.cglib.proxy.Enhancer.getDefaultClassLoader (Enhancer.java:386):

protected ClassLoader getDefaultClassLoader() {
if (superclass != null) {
return superclass.getClassLoader();

Superclass is org.eclipse.emf.cdo.internal.protocol.model.CDOFeatureImpl
in this call.

Maybe this is a bug in CGLib or Hibernate, because it implicitly assumes
that the class loader of the super class of a class to persist is able
to locate the HibernateProxy interface, which is not the case here. As a
workaround, I add the Eclipse-BuddyPolicy: dependent property to the
*org.eclipse.emf.cdo.protocol *bundle as well.

.... works (well, a bit): I am able to create the repository, session and
transaction, I can create my model and add it to a newly created repository.
However, I am not able to commit, because for some reason, the
cdo_resource table is not created.

Hi Stefan,

Looks as if you entered dependency hell ;-(
Only recently I stumbled over weird behaviour of PDE or OSGi which was
related to the "jars.extra.classpath" in some build.properties file. I had
the feeling that, once configured, PDE caches the chosen jar location and
it's hard to get rid of that cached setting. The result was that it always
searched for classes in that location although I already removed the
property from the build.properties. I really can't explain it better but I
was able to get rid of the hazzle by turning all "jars.extra.classpath"
properties by "bin.includes" + "Bundle-Classpath" (in MANIFEST.MF). Maybe
this is of help for you.

Nick and I also have hard times to integrate the Hibernate stuff into the
automated builds and tests ;-(

Cheers
/Eike

Hi Eike,

well as of now, I "only" have the problem that the CDOResource does not
register itself, or Hibernate does not create a table for this,
respectively.
Do you have any idea why this could be?
Does not intuitively seem to be a dependency issue.

Cheers
Stefan

Solved that issue by setting

props.put("hibernate.hbm2ddl.auto","update");


Now I get a


org.hibernate.id.IdentifierGenerationException: ids for this class must
be manually assigned before calling save(): MyNode

This one should be solveable.
As you might have guessed, MyNode is an element from my own model.

How do I have to prepare my model in order to be able to work with
CDO-Teneo-Hibernate?
And more particularly, how do I assign the id for my model class?

This is my test model:

<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

nsPrefix="mycontainer">
<eClassifiers xsi:type="ecore:EClass" name="MyContainer">
<eStructuralFeatures xsi:type="ecore:EReference" name="contents"
upperBound="-1"
eType="#//MyNode"/>
</eClassifiers>
<eClassifiers xsi:type="ecore:EClass" name="MyNode">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="text"
eType="#//EString"
defaultValueLiteral="" iD="true"/>
</eClassifiers>
<eClassifiers xsi:type="ecore:EDataType" name="EString"
instanceClassName="java.lang.String"/>
</ecore:EPackage>

Thanks all the time for your support!

Cheers,
Stefan

Hi Stefan,
As a default Teneo will use the eattribute with id=true as the primary key of the eclass. In your
case the eattribute text has id=true. Afaics in your case you tried to persist an instance with a
null-value in the text eattribute which is not allowed (as it is the pk). You can either set this
eattribute before saving, or disable this default teneo behavior. For this you can set the option
PersistenceOptions.ID_FEATURE_AS_PRIMARY_KEY to "false". If you do this then a synthetic primary key
will be used.

Hi Stefan,
See comments below/inline marked with MT>>.

Btw, here is a small first page on the cdo-teneo-hibernate integration, it is maybe not complete and
afaics you already know most of it:
http://www.elver.org/hibernate/cdo.html

Hi Martin,

Great intro! As usual I'm behind with my docs ;-( But I promise that I'lll
work on them when my current customer engagement ends mid of May...

Cheers

Hi Stefan,

You seem to have invested a lot of time to make it run. Most of the steps
you describe look necessary and appropriate to me.

As soon as I have more time available again I plan to create a space in
the wiki where users can persist reports about their experiences.

More comments inline...

Cheers
/Eike

Interesting, will have to look at this one. I remember that once there was
a discussion whether the incubating components (like net4j, cdo and teneo)
can become part of this distro. Will put this on my list ;-)

The one in plugins/ is obsolete since Martin joined the component as a
committer and I moved everything to the hibernate/ folder. Are both
folders non-empty in HEAD? If yes, could you please file a Bugzilla so
that I won't forget about it during the weekend?

Oh yes, this non-EPL 3rd party library stuff is really annoying!! If only
the platform itself had a mechanism to automatically provision such
dependencies ;-(

Looks ok to me.
Please notice that with the latest sources you can't register subpackages
directly anymore. They're autpomatically registered along with their top
level packages! Just in case...

Maybe we can create a fragment for the net4j.db plugin (which contains
several jdbc drivers via adapter fragments) that adds an additional
dependency on the hibernate.mapper plugin, so that the BuddyPolicy will
make the driver jars visible. Martin?

This looks like a pure Hibernate problem and I guess it's best to wait for
Martin's analysis ;-)

Happy persisting!

Hi,

today, I learned that Eclipse is always good for some extra fun.
For some reason it deleted the
<classpathentry kind="con" path="org.eclipse.pde.core.requiredPlugins"/>
from the .classpath file in all project in my workspace. It is creepy
when Eclipse does not find a single dependency anymore.
Luckily I was able to locate the problem after some time - so now I am
back and ready to proceed.

Thanks, Martin, for all your comments. As you might have guessed, most
errors I wrote were simple typos / paste errors:

Sure - this was just to report that it could cause misunderstandings.
@Eike: the folder in plugins is empty, you just get a conflict, if you
try to check out everything at once because of two folders / projects
with the same name.

Mhh .. it is not required and AFAIK there's only commons-logging.jar in
there, which has to be copied into
org.eclipse.emf.cdo.server.hibernate.libraries/lib anyway.

You're right - one could completely leave out the net4j.db.* libraries
when using Hibernate.

Hmmm ... maybe that depends on how it is used / deployed?
I get build errors that those two libraries can not be resolved.

I created a new test plugin for my own stuff. But if I place the mysql

Yes.
The problem is, as far as I can see after some debugging, a classloader
problem.

The mapping which makes problems is

[...]
<joined-subclass name="CDOFeatureImpl" table="cdo_features"
extends="CDOModelElementImpl">
<key/>
<property name="featureID" column="feature" type="int"
not-null="true" />
/ <property name="type"
type=" org.eclipse.emf.cdo.server.internal.hibernate.tuplizer.CDOTy peUserType "
not-null="false" />
/[...]

from org.eclipse.emf.cdo.server.hibernate/mappings/meta.hbm.xml

When the schema is to be created, hibernate iterated through the
mappings and comes to the mapping above.
Then we are at org.hibernate.mapping.SimpleValue.getType() (line 260)

Type result = TypeFactory.heuristicType(typeName, typeParameters);

where he tries to load the type via ReflectHelper.classForName( typeName
); and fails.

After some trial and error, I found out that adding

Eclipse-BuddyPolicy: dependent

to the MANIFEST.MF of org.eclipse.emf.cdo.server.hibernate.libraries
does the trick. With this policy set, the class is found and I can even
again delete the mysql driver class from
org.eclipse.emf.cdo.server.hibernate.libraries.

I don't know quite much about classloading in Eclipse (or OSGi,
respectivly), this is very much magical to me, but can it be, that the
missing Eclipse-BuddyPolicy in
org.eclipse.emf.cdo.server.hibernate.libraries is a bug? But then, this
may as well be the result of my "non-standard" installation (copying
jars to org.eclipse.emf.teneo.hibernate.mapper)...


Ok, next one: I'm running into a net.sf.cglib.core.CodeGenerationException

Again a classloader problem, I think.
Tried a lot of alternatives of moving hibernate3.jar around and create
and delete copies of it.
No effect.

Giving up for today - maybe there's some light of wisdom coming to me
(or you?).

Anyway, have a nice weekend

MT2>> Yes I was/am actually surprised that our testcases run without this Eclipse-Buddypolicy
setting, so setting it seems a good idea.

MT2>> Eclipse-Buddypolicy dependent means that a plugin will search for classes
in the plugins which depend on it. An example, say that you have a plugin A which depends on plugins
B and C. Now assume that A passes a config file (a mapping file) to B which contains the name of a
class which is served by C. Then with Eclipse-Buddypolicy dependent in B the following will happen:
- B will try to resolve the class, but it can't as the class is not present in his own plugin
- B then asks A because A depends on B and B has Eclipse Buddypolicy dependent
- A tries to load the class but fails so it checks C
- C has the class and loads it and gives it back.

As you can see for libraries like hibernate which instantiate classes from other plugins which are
outside of the visibility of hibernate, Eclipse-buddypolicy dependent is a required feature. Note
that eclipse buddy policy dependent is not very good from a performance point of view as the class
loading process has to go through all these plugins.

MT2>> I have looked at the exception below but I can't really think why this occurs.
Do you have a cglib jar in another plugin maybe can you check that?
If you can put in a small test project and email it to me then I can try to replicate it.

You seem to have updated build.properties yesterday so now there's no

Is there a testcase using an embedded server/client (meaning: a net4j
JVM connection?). I guess a lot of the trouble is caused by this setting.
I can run the standalone hibernate server for the testcases with no
problem, but has any of you two tried testing with server and client
inside one JVM?

I started over and wiped my workspace today.
I checked out:

org.eclipse.emf.cdo
org.eclipse.emf.cdo.protocol
org.eclipse.emf.cdo.server
org.eclipse.emf.cdo.server.hibernate
org.eclipse.emf.cdo.server.hibernate.id
org.eclipse.emf.cdo.server.hibernate.libraries
org.eclipse.emf.cdo.server.hibernate.teneo
org.eclipse.emf.teneo
org.eclipse.emf.teneo.annotations
org.eclipse.emf.teneo.hibernate.mapper
org.eclipse.net4j
org.eclipse.net4j.jvm
org.eclipse.net4j.util

and added these libraries:

/org.eclipse.emf.cdo.server.hibernate.libraries/lib/asm.jar
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/cglib-2. 1.3.jar
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/commons- collections-2.1.1.jar
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/commons- logging-1.0.4.jar
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/dom4j-1. 6.1.jar
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/hibernat e3.jar
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/jta.jar

and (for now):
/org.eclipse.emf.cdo.server.hibernate.libraries/lib/mysql-co nnector-java-5.1.5-bin.jar

I also added the mysql libraries to the runtime classpath.
To analyze class loading problems I turned on tracing of "debug/loader"
of the org.eclipse.osgi bundle.

With this configuration I get this issue:

29.04.2008 11:06:58 org.hibernate.cfg.Configuration

Ok - the problem seems to be that the
org.eclipse.emf.cdo.server.hibernate.libraries Bundle where
hibernate3.jar lives does not see org.eclipse.emf.cdo.server which
defines the mapping types.

Idea: add Eclipse-BuddyPolicy: dependent.
Thus, I also can move the mysql-driver to my test case Bundle.

This leads to:

As far as I can see, Java tries to load the class
*org.hibernate.proxy.HibernateProxy* from the bundle
*org.eclipse.emf.cdo.protocol_0.8.0.qualifier*. Why so? I think because of

net.sf.cglib.proxy.Enhancer.getDefaultClassLoader (Enhancer.java:386):

protected ClassLoader getDefaultClassLoader() {
if (superclass != null) {
return superclass.getClassLoader();

Superclass is org.eclipse.emf.cdo.internal.protocol.model.CDOFeatureImpl
in this call.

Maybe this is a bug in CGLib or Hibernate, because it implicitly assumes
that the class loader of the super class of a class to persist is able
to locate the HibernateProxy interface, which is not the case here. As a
workaround, I add the Eclipse-BuddyPolicy: dependent property to the
*org.eclipse.emf.cdo.protocol *bundle as well.

.... works (well, a bit): I am able to create the repository, session and
transaction, I can create my model and add it to a newly created repository.
However, I am not able to commit, because for some reason, the
cdo_resource table is not created.

Hi Stefan,

Looks as if you entered dependency hell ;-(
Only recently I stumbled over weird behaviour of PDE or OSGi which was
related to the "jars.extra.classpath" in some build.properties file. I had
the feeling that, once configured, PDE caches the chosen jar location and
it's hard to get rid of that cached setting. The result was that it always
searched for classes in that location although I already removed the
property from the build.properties. I really can't explain it better but I
was able to get rid of the hazzle by turning all "jars.extra.classpath"
properties by "bin.includes" + "Bundle-Classpath" (in MANIFEST.MF). Maybe
this is of help for you.

Nick and I also have hard times to integrate the Hibernate stuff into the
automated builds and tests ;-(

Cheers
/Eike

Hi Eike,

well as of now, I "only" have the problem that the CDOResource does not
register itself, or Hibernate does not create a table for this,
respectively.
Do you have any idea why this could be?
Does not intuitively seem to be a dependency issue.

Cheers
Stefan

Hi,

Solved that issue by setting

props.put("hibernate.hbm2ddl.auto","update");


Now I get a


org.hibernate.id.IdentifierGenerationException: ids for this class must

This one should be solveable.
As you might have guessed, MyNode is an element from my own model.

How do I have to prepare my model in order to be able to work with
CDO-Teneo-Hibernate?
And more particularly, how do I assign the id for my model class?

This is my test model:

<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

nsURI="http://www.fernuni-hagen.de/ST/mycontainer.ecore"
nsPrefix="mycontainer">
<eClassifiers xsi:type="ecore:EClass" name="MyContainer">
<eStructuralFeatures xsi:type="ecore:EReference" name="contents"
upperBound="-1"
eType="#//MyNode"/>
</eClassifiers>
<eClassifiers xsi:type="ecore:EClass" name="MyNode">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="text"
eType="#//EString"
defaultValueLiteral="" iD="true"/>
</eClassifiers>
<eClassifiers xsi:type="ecore:EDataType" name="EString"
instanceClassName="java.lang.String"/>
</ecore:EPackage>

Thanks all the time for your support!

Cheers,
Stefan

Hi Stefan,
As a default Teneo will use the eattribute with id=true as the primary key of the eclass. In your
case the eattribute text has id=true. Afaics in your case you tried to persist an instance with a
null-value in the text eattribute which is not allowed (as it is the pk). You can either set this
eattribute before saving, or disable this default teneo behavior. For this you can set the option
PersistenceOptions.ID_FEATURE_AS_PRIMARY_KEY to "false". If you do this then a synthetic primary key
will be used.

gr. Martin
