Re: [bpel-dev] Bpel process generation... help needed
|
Well, w.r.t dynamically composing a service during runtime - I think it is
a domain issue, which means if you think you have enough information
available I think you can do it. As for "how" to do it, that, as usual,
depends on what is available in the environment where you want to do this.
Given that you want to construct a process and auto-deploy it, I guess
generating all the files + then use ANT to deploy to e.g. ODE sounds OK to
me (without having looked too much at the details), however, the base
question I assume is what you have available. Seems like you have wsdl4j
and wsif, also it seems like that you don't have eclipse+emf (not even
headless), thus I believe you cannot properly use the existing bpel model.
Thus, to create your process, you'd need to use different technologies like
e.g. creating the BPEL XML directly by populating a DOM tree and saving it,
or maybe by using JAX-B or .... - your choice then.
PS: I understand that using the BPEL model outside of eclipse might be
desirable, but it was never intended by us. Thus, this isn't supported

Ok, thank you.
I think I will have to re-invent wheel a bit (like wsdl4j). or any other
suggestion?. anyways thank you for helping.
But do you "think" the approach am gonna use, is feasible for composing the
services at run. Just an opinion.

Don't think so - at least I never tried it. You could maybe run this in a
headless eclipse, but the BPEL model uses EMF etc. and I doubt that you
could have all o
this running outside eclipse. In a headless eclipse that might work (that
means that you have to have a headless eclipse running in your runtime
evironment], but I never tried this, so I cannot give you hints on this.

Hi,
thanks.
Well the version of eclipse is 3.4 and the Bpel designer is of 0.4.0.
Actually scene is that I want to compose the couple of services (for now)
at runtime. For that I am generating a wsdl using wsdl4j (and wsif for xsd)
and now i need to generate the bpel. For that I wanted to use some api like
wsdl4j. Would I have to stick with the eclipse to generate bpel? because
what i was thinking is that I will generate wsdl, xsd(if there is a need),
bpel and deployment script, and will throw these things into ode using ant.
( will be happy if you comment on this).
Can generate the bpel without using eclipse but eclipse plugin-jars? if yes
then how could i do that.
regards,
----

First of all, all of the issues that you mention are pure EMF things ... so
you might want to read up on EMF and FileUris vsa. PlatformResource URIs a
little bit.
Second, I tried this code on my machine:
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;
}
And it worked like a charme. Note that you have to have a project called
"myProject" in your workspace in order to make this run.
Is it possible that you run outside of an eclipse workspace ? What version
of the BPELDesigner and what version of Eclipse are u using ?

Some sample code that should help you ...
protected Process createBPEL(){
Process process = null;
try {
//create resource
URI uri = URI.createPlatformResourceURI(
"/myProject/myBPEL.bpel", false);
bpelResource = getResourceSet().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;
}
You dont have to call the writer explicitly ... calling bpelResource.save()
should do the trick

Hi,
I want to generate the bpel process (xml), I tried to roam around the
classes like BPELWriter, BPELFactoryImpl, BPELResourceImpl etc...
What I am trying to do is that creating Process and its children form
BPELFactoryImpl and then want to use write(BPELResource, OutputStream)
method.
first am i assuming it right and second how can i add Process to
BPELResource
regards,
