[AXIS2] Admin Tools

Hi,

I'm trying to prototype a couple of things with the axis2 engine to see how it works (I down loaded 0.9).  In particular, I want to start with a wsdl and generate the necessary artifacts.  I'd like to do this from a web service (e.g. use a web service to generate other web services).  I can generate the wsdl on the fly.  Can I then use your org.apache.axis2.deployment classes to generate the artifacts and then hot deploy them in the current engine on the server?  Are the admin classes ready to be poked?  I didn't see any samples and the javadoc is sparse in this area.  Do you still have the notion of jws file in axis2?  I didn't know if that was still an alternative to generating the wsdl.

I also want to include attachments in my generated web services.  I took the doc-lit SwA sample from WS-I BP Attachment document and tried to use wsdl2java to create the service deployment code and I'm getting the following error:

Exception in thread "main" java.lang.RuntimeException: org.apache.xmlbeans.XmlException: error: cvc-complex-type.2.4a: Expected elements 'annotation@http://www.w3.org/2001/XMLSchema simpleType@http://

It seems to not like attachment types of "base64Binary".  Are you aware of this problem?

Here's the wsdl from the WS-I page:

Hi Tony,
To me it seems that you need to run the code generator on the fly, compile 
the code and then host a service.(all within some code)
Here are some hints that you'll find useful.
1. Code generator can be easily invoked programmatically. See the 
WSDL2JavaTest.java in the wsdl module for an example.
2. Once the classes are available, you can host the service programmatically 
(by invoking the deployment) or for an easier solution generate a service 
archive and copy it to the repositiry directory.

We still don't have anything resembling jws yet.

Hmmm... Seems to me that XMLBeans finds something confusing in the schema 
part. I will check, thanks for pointing out the problem
