EMF Form Editor for a WS-Policy ecore model [message #639908]

Hi,

I am creating a form editor based on the generated classes usinf the EMF generator. Therefore I have created a genmodel of the WS-Policy and WS-SecurityPolicy specifications. Futhermore I created ecore models on the depending specifications as well.

When I now try to load a serialized policy.xml the generated editor or my created form editor give a NullPointerException. Only the Sample Reflective Ecore XML Editor seemed working.
Sometimes the generated editor also shows data when I name the file in 'policy.policy' using the same file.

Anyway I prefer to create a form editor using also *.xml if it is possible.

It would be if anybody could give a hint.

Thanks in advice
Best regards
Tom

I assume your model has two classes, Policy and Security Policy? I also
assume you created an ecore, a genModel and generated code? Maybe you
could describe that a little more in detail?

Is that the exception down below? That is a classnotfound. Check whether
Policy is abstract. If so, you cannot create it. Can you describe how
you exactly load xml into the editor? There is something with jdt in the
stack trace...

What do you mean by sometimes?

Hi Jonas,

I have created a genmodel including the 8 ecore models (e.g. the ws-policy and ws-security-policy). All of the I have generated based on the xsds of ths specifications from the w3c and open oasis.
Furthermore I generated th model code, the edit code and the editors. That was done more or less fast.

Now I have a policy.xml that I open in the workspace with one of the generated editors (more than one cause of the different ecores), when a new eclipse enviroment was started. None of the editor can open the file of the ClassNotFoundException (no Nullpointer, sorry!).

>What do you mean by sometimes?

I meant that I had configurations when I did work to show a policy.policy in the generated editor, the extension of the particular generated editor. I tried to change the file extension in the plugin.xml but it still accepted the '*.policy'.

The point of the exception is that a policy.class does not exist. The transfomation from the wspolicy.xsd to the ecore put the policy as a ereference into the documentRoot (like shown below).
In java classes that means I have a 'DocumentRoot.java' containing the methods

PolicyType getPolicy();

and

void setPolicy(PolicyType value);

Best Regards,
Tom

Is your generated resource factory registered against this extension?

I imagine that registering against *.xml might be in conflict with
others. Likely you should be using the content type support if you need
to handle such a general extension...

Check carefully which type of resource is being createed.

Hi,

I register the created ItemProviderAdapterFactories like done in the generated editors. But when I like to create a resource, there is no content.
The DocumentRootImpl is used in the generated editors to provide the 'Policy' element and apears in the content of the resource.
In my own built editor it still give the error which I already mentioned.
Where is the content set exactly?

Do I need to register the ResourceFactory more often than only in the initializeEditingDomain() ? You said against the extension.

Thanks for your advices.
Regards

Tom
