Re: [bpel-dev] BPEL Parsing
|
Hi Simon,
Thank you for help.
I just tried your code and after a big dependencies problems i noticed
that there are some restriction to the use of some libraries
like : org.eclipse.bpel.model.resource.BPELResourceSetImpl;
or even i find that in the bpel.ui.util there is the class BPELReader, i
wanted to use it and specially use the read(..) method the samething
there is restriction rule for using this class
i remind that i created a new plugin project with the all necessary
plugin dependencies concerning eclipse.bpel and other emf stuff
also one another thing some packages won't be found with just
org.eclipse.bepel.* but we have to add the bin in front to be
bin.org.eclipse.bpel.*
Thank you

Hi Iyad,
here's some sample code to do this: Write your own eclipse plugin, and
**assuming ** your file is in your eclipse runtime workspace, this can be
done as follows:
IPath path = new Path("/pathToMyBPELFile/myFile.bpel");
IFile bpelFile = ResourcesPlugin.:getWorkspace().getRoot().getFile
(path);
loadBPEL(bpelFile);).
protected Process loadBPEL(IFile bpelFile) {
ResourceSet fResourceSet = new BPELResourceSetImpl();
IPath fullProcessPath = bpelFile.getFullPath();
URI uri = URI.createPlatformResourceURI
(fullProcessPath.toString(), false);
bpelResource = fResourceSet.getResource(uri, true);
EcorePackage instance = EcorePackage.eINSTANCE;
instance.eAdapters();
try {
bpelResource.load(Collections.EMPTY_MAP);
EList<EObject> contents = bpelResource.getContents();
if (!contents.isEmpty()) {
return (Process) contents.get(0);
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
Similar code exists in the loadModel() method of the BPELEditor class in
the bpel.ui plugin. Now you have the EMF Process-root EObject, that has the
in-memory representation of this. You can now read/modify this using
standard EMF methods.
For each EMF object (such as Process) there is also a method getElement()
which returns you the DOM Element - not sure why you'd need that though.
Parsing with EMF is much more conveniant. Let me know if that answered your
question.
Mit freundlichen Grüßen / Kind regards

Subject: [bpel-dev] BPEL Parsing
Sent by: bpel-dev-bounces@xxxxxxxxxxx
Hello
I'm new to BPEL designer project ,
I'm working on a project wich will use the BPEL designer, what i need is
how to parse a .bpel file generated by the BPEL designer or other tool?
and where is it handled? I have seen some examples using the Process as
the main object for BPEL file using the Ecore model of BPEL and what
about DOM representation?
Does any one have an example ?
Thank you for help.
