Java2WSDL Ant problem

[Stefan Klinger <kl...@cs.york.ac.uk>]

Hello,

I am trying to generate the wsdl interface description using the Ant 
java2wsdl build task. I have attached the build.xml file and the actual 
class to this mail. When I run the Ant Task, I get the following error. 
I have tried with different java classes, always with the same result. 
When I rename the java file to jws and place it in the Axis webapps 
directory, it generates the wsdl just fine! Any ideas?

[java2wsdl] - Unable to find required classes 
(javax.activation.DataHandler and
javax.mail.internet.MimeMultipart). Attachment support is disabled.

Your task must specify the target namespace:

<java2wsdl output="LoanBrokerWS.wsdl" 
   className="com.ttdev.simpleservice.LoadBrokerWS"
   namespace="urn:com.ttdev:simpleservice"
   location="http://localhost:8080/axis/LoanBrokerWS">
</java2wsdl>
