Anne and Thilina,
thanks a lot for taking the time to reply.
Actually I need *libraries*, not tools, to generate all those
artifacts, since I'm developing a modelling tool to create service
compositions and services. I pass the model on to a generator, which
would then need libraries for BPEL, XSD, and WSDL, to write out all
the artifacts.
As it turns out, the Eclipse library for XSD generation and WSDL4J
work quite well now. I will now look into the Eclipse model classes
for BPEL files to see whether I can use those to write out BPEL. The
Eclipse BPEL Designer that Thilina spoke of also uses them, so it's
only a question of the quality of integration achievable with them.
So instead of trying out all available libraries myself, I'd thought
maybe someone on this list could share some experiences. But as this
is not really the topic of this list, I'm perfectly fine with
examining them myself.
Again, thanks for your replies.
Leif
You can use a WSDL generator, such as Axis2 java2wsdl, to generate
both a WSDL and embedded XSDs from your Java objects. You might also
consider using an XML binding framework, such as XMLbeans or JAXB, to
generate just the XSD files from your Java objects. (You can also use
a binding framework in conjunction with the WSDL generator.)
I don't know of any tool that generates BPEL from Java -- that's not
what you would normally do -- you typically specify the process flow
using a modeling notation (UML, BPMN, etc) and generate the BPEL
execution script from the model. (i.e., you write the processing logic
in BPEL rather than in Java). I suggest you look at ActiveBPEL
(http://www.active-endpoints.com/active-bpel-engine-overview.htm) for
your BPEL engine.

Hello,
I know this is quite off-topic, but since the list I suppose would be
most fitting for my question didn't respond at all, so I thought I'd
give it a shot here.
I have a model of a business process available as java objects. Out
of
this, I want to generate BPEL, WSDL, and XSD files. I have tried
several libraries for these tasks:
XSD: XmlSchema by Apache Commons, Eclipse's XSD library
WSDL: WSDL4J
BPEL: my own lacking implementation, planning to try Eclipse's BPEL
library
To make sure I'm understood, I need these libraries to
- provide a mechanism to construct an object graph representing an
XSD/
WSDL/BPEL file
- be able to write this object graph to a file
I also need them to read in existing files, but only for XSD and
WSDL.
My questions:
1. Can anyone recommend which libraries to use for these tasks?
2. Using XmlSchema from Apache Commons, I was able to build the
structure just fine, but when trying to write it out, I only find an
empty <schema/> element -- is there anything tricky that I am
obviously doing wrong and should know, e.g. setting a flag for each
object that needs to be added or something like that?
Again, sorry for the off-topic post, but I thought the audience of
this list might contain some indiviuals who know these things. If
someone can point me to the proper list where to ask this, I'd of
course be interested, too.
Thanks in advance
Leif Singer
