| Re: [bpel-dev] Using BPELReader Class |
Hi Damien,
**assuming ** your file is in your eclipse runtime workspace, this can be
done much, much simpler :
IPath path = new Path(
"/home/damien/Workspaces/BPEL/org.example.loadbpel/bpel/ldiplom.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;
}
The path might not be correct in my example - it might be that you must
only specify the path starting from your workspace root instead of having
the full path - give it a try.
Alternatively, *if* you want to launch whatever you are doing using a
right-click menu on the bpel process, let me know, I can send you a sample
plug-in for that, too.

Subject: [bpel-dev] Using BPELReader Class
Sent by: bpel-dev-bounces@xxxxxxxxxxx
Hello,
I have been trying to use the BPELReader class to read a .bpel file and
obtain the BPEL process it defines, using the getProcess() method from
that class.
Unfortunately, I haven't been able to make it work yet.
I am using the following code. I took most of it from some test cases I
found and I have to admit, I don't really know what I am doing :)
File inputFile = new
File
("/home/damien/Workspaces/BPEL/org.example.loadbpel/bpel/ldiplom.bpel");
ResourceSet fResourceSet;
// Create the Quasi-Eclipse environment ...
AdapterRegistry.INSTANCE.registerAdapterFactory( new
org.eclipse.bpel.validator.factory.AdapterFactory() );
AdapterRegistry.INSTANCE.registerAdapterFactory( BPELPackage.eINSTANCE,
BasicBPELAdapterFactory.INSTANCE );
// Create a resource set.
fResourceSet = new BPELResourceSetImpl();
// Register the resource factories for .bpel, .wsdl, and .xsd resources.
// - bpel reads BPEL resources (our model)
fResourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put(
"bpel", new BPELResourceFactoryImpl()
);
fResourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put(
"wsdl", new WSDLResourceFactoryImpl()
);
// - wsdl reads WSDL resources (from wst project)
// WSDL also needs to know about the extensions to WSDl that we provide,
namely
// partner links, variable properties, etc.
// We need to register them someplace here ...
fResourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put(
"xsd", new XSDResourceFactoryImpl()
);
// - xsd reads WSDL resources (from wst project)
fResourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put(
"fnmeta", new FMResourceFactoryImpl ()
);
// Register the real model query interface, that knows about EMF world
as well.
ModelQueryImpl.register( new ModelQuery() );
// The function library is late bound. When eclipse is running, this
information
/ / is registered via the plugin's descriptor. On its own, we have to do
it another way.
FunctionLibrary.INSTANCE.registerLoader( new
ClasspathFunctionRegistryLoader (fResourceSet) );
// To have a valid logger
BPELPlugin foo = new BPELPlugin();
BPELPlugin.Implementation impl = new BPELPlugin.Implementation();
//
//Step 1. Read the BPEL process using the Model API.
BPELReader reader = new BPELReader();
reader.read(inputFile, fResourceSet );
Process process = reader.getProcess();
Unfortunately, when I run this, it returns a null process and when
looking into it, the parsing ends with the following error message
"Fatal Error in
file:/home/damien/Workspaces/BPEL/org.example.loadbpel/bpel/ldiplom.bpel
[778:21] XML document structures must start and end within the same
entity."
That surprises me since I can open this file without any problem using
the BPEL Eclipse project.
Does anyone have any idea what I am doing wrong?
I would like to be able to manipulate the "process" of my BPEL file.
Many thanks in advance,
