| Re: [bpel-dev] generate the .bpel file from an EMF model |
Thank you for your reply I used the code example
you give me
to generate a .bpel file as shown in the following example
public static void main(String[] args) {
Process process = null;
try {
// Register the XMI resource factory for the .bpel extension
Resource.Factory.Registry reg =
Resource.Factory.Registry.INSTANCE;
Map<String, Object> m = reg.getExtensionToFactoryMap();
m.put("bpel", new BPELResourceFactoryImpl());//difference avec XMIResourceFactoryImpl() et XMLResourceFactoryImpl()
//create resource
URI uri =
URI.createFileURI("//myBPEL2.bpel");
ResourceSet rSet = new ResourceSetImpl();
Resource bpelResource = rSet.createResource(uri);
//create/populate process
process = BPELFactory.eINSTANCE.createProcess();
process.setName("myBPEL");
Sequence mySeq = BPELFactory.eINSTANCE.createSequence();
mySeq.setName("mainSequence");
process.setActivity(mySeq);
//save resource
bpelResource.getContents().add(process);
bpelResource.save(null);
}
catch (Exception e) {
e.printStackTrace();
}
}
}
But if i use the BPELResourceFactoryImpl as the extension parser for .bpel files
I have the following exception
java.lang.IllegalStateException: INamespaceMap cannot be attached to an eObject
at org.eclipse.bpel.model.util.BPELUtils.getNamespaceMap(BPELUtils.java:261)
at org.eclipse.bpel.model.resource.BPELResourceImpl.doSave(BPELResourceImpl.java:88)
at org.eclipse.emf.ecore.resource.impl.ResourceImpl.save(ResourceImpl.java:1406)
at org.eclipse.emf.ecore.resource.impl.ResourceImpl.save(ResourceImpl.java:993)
at bpelgen.Test.main(Test.java:49)
And if I use the XMLResourceFactoryImpl as the extension parser for .bpel files it generate .bpel file but with rang namespace
<?xml version="1.0" encoding="ASCII"?>
<bpws:Process xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:bpws="http://docs.oasis-open.org/wsbpel/2.0/process/executable" name="myBPEL">
<activity xsi:type="bpws:Sequence" name="mainSequence"/>
</bpws:Process>
-------------------------------------------
<activity xsi:type="bpws:Sequence" name="mainSequence"/>
instead of
<bpws:Sequence name="mainSequence"/>
so could you tel me if I have to use the XMLResourceFactoryImpl or the BPELResourceFactoryImpl and in the secend case how can I resolve the INamespaceMap cannot be attached to an eObject exception
regards,
Again, I don't think you can use our BPELWriter for this. The way this
works today is the following:
The BPELReader uses a regular DOM parser to populate the EMF in-memory
model. The BPEL Editor then works on the in-memory model, and then on save,
the in-memory model gets translated back to a DOM tree which is serialized
as XML again. As such, both the BPELReader and the BPELWriter assume
certain knowlegde about the XML that they consume/provide. If you created
your own model (even if its an instance of the BPEL ecore), those
assumptions might not be true anymore, certainly not in the case where you
pass in an XMI file. Thus, you'd need to write your "own" BPELWriter (or
extend our BPELWriter / BPELReader) such that your Reader/Writer is able to
understand both XMI and your eCore (and potentially more, e.g. Your own
BPELResource that probably already exists).
In case you can go with our BPEL model, below is little sample code that
creates a simple .bpel File:
protected Process createBPEL(){
Process process = null;
try {
//create resource
URI uri = URI.createPlatformResourceURI
("/myProject/myBPEL.bpel", false);
ResourceSet rSet = new ResourceSetImpl();
bpelResource = rSet.createResource(uri);
process = BPELFactory.eINSTANCE.createProcess();
process.setName("myBPEL");
Sequence mySeq = BPELFactory.eINSTANCE.createSequence();
mySeq.setName("mainSequence");
process.setActivity(mySeq);
bpelResource.getContents().add(process);
bpelResource.save(null);
}
catch (Exception e) {
e.printStackTrace();
}
return process;
}
Note that you have to have a project called "myProject" in your workspace
in order to make this run. Note also that I don't call the writer
explicitly, but only do save() on the EMFResource (which is a
BPELResource). This triggers the writer under the covers.

Hi,
I have created my own EMF model it's an instance of the bpel.ecore Met
model (the instance can be an xmi or an xml file)
and I want to generate the ( .bpel) file from this EMF model so I need to
use the BPEL Writer
am i assuming it right and if so could you give Some sample code on how to
generate a .bpel file from an existing own EMF model
regards,

BPEL Reader and BPEL Writer most certainly don't work with an XMI

Where do you have that XMI from ? Did you create your own EMF model ?
Currently, the BPEL Reader and BPEL Writer populate/serialise to/from
an
EMF model that exists (org.eclipse.bpel.model). However, the inout
and
output must always be standard BPEL 2.0 XML syntax, not XMI. I don't
think
you can use the BPEL model for what you are trying to achieve (but I
admit,
I havent fully understood what you are trying to do).

Hi,
I want to generate the .bpel file (myBpel.bpel) from an EMF model
(myProcess.xmi) already created
I tried to roam around the classes like BPELWriter, BPELFactoryImpl,
BPELResourceImpl etc...
What I am trying to do is to load the Process form the xmi file (EMF
model)
and I then want to use write(BPELResource, OutputStream) method to to
generate the .bpel
first am i assuming it right and second could you give me example for
loading process from xmi fil and generating .bpel file
