Re: still about how to generate BPEL process without GUI designer

It supposed to be that openide.util is the *only* small basic NB module needed for using this stack:

..bpel.model
..wsdl.model
..wsdlext
..schema.model
..xam

I just discovered some unwanted dependencies introduce since the sierra merge.  We have removed the extra dependencies.  You can try out the following code after get the latest daily NB build at http://bits.nbextras.org/download/trunk/nightly/latest/

To create a bpel model, do something like this:

         File bpelFile = new File(pathToSourceFile);
         Lookup lookup = Lookups.fixed(new Object[]{
                bpelFile,
                myLoadPlainDocumentMethod(bpelFile),
                myCatalogModel,
            });
         ModelSource source = new ModelSource(lookup, editable);
         BpelModelFactory factory = Lookup.getDefault().lookup(BpelModelFactory.class);
         BpelModel model = factory.getModel (source);

For more detail on myCatalogModel, look at file CliValidateBpelProjectDelegate in bpel.project module.  You can reimplement it quickly removing dependency on the retriever Utilities.

Hi Jason,

Thank you for the reply. Since there are existing codes for generating BPEL, I prefer not to
reinvent the wheel :-)

Eclipse BPEL also provides an open source BPEL model, which is more clear and simple than
NetBeans'. However, since I want to use NetBeans execution engine to run the BPEL process, I'd
better use NetBeans' BPEL model to generate BPEL file to make sure the compatibility. 

Anyway, I really don't think there is no way to re-use NetBeans BPEL model to generate BPEL file
without GUI.

Any hint will be greatly appreciated!

Hi Sam,

BPEL is just an XML document. Why can't you just use XML apis to 
programmatically create the BPEL XML document and then import it into 
netbeans?

Dear all,

I just checked the source code of BPEL, I found that the BPEL model seems tightly coupled with
      

NB
    

GUI. For example, first I want to generate a blank BPEL process through:
org.netbeans.modules.bpel.model.impl.BpelModelFactoryImpl

However, I need to get "org.netbeans.modules.xml.xam.ModelSource", which tightly coupled with
      

the
    

NB GUI through "org.openide.util.Lookup". I don't know how to instantiate "Lookup".

Another potential approach seems through
"org.netbeans.modules.bpel.project.BpelproProjectGenerator". However, it only creates an empty
"EjbProject". I have two questions about "EjbProject". First, if it can be treated as a "BPEL"
project. Second, if it can be treated as a "BPEL" project, how can I create a very simple
"synchronizing BPEL example", just like the example provided by NB SOA. Or simpler, I can
      

generate
    

this simple BPEL project through NB GUI first, and then trying to load this project into some
class in order to retrieve the BPEL process with the resources. But I don't know how to do
      

this. I
    

think once I get the BPEL instance, I can manipulate it through all the classes in the package
"org.netbeans.modules.bpel.model.impl".

In a word, my requirement is very simple. First, I want to generate a quite simple BPEL
      

process as
    

the template (just like the synchronizing BPEL example provided by NB SOA example), then
manipulating this BPEL process through NB's BPEL model (for example, adding activities such as
"receive", "reply", "invoke","assign", etc.)

Since this is part of my Ph.D research and I am in huge pressure to graduate, any quick
hint/suggestion will be greatly appreciated!!

Sam
