Dynamic proxy problems

Question

Hi,
I'm working on making my own dynamicproxy client. I simply copied
and renamed the old dynamicproxy to HW5dynamicproxy and then change
the service endpoint in the build.properties file and removed the ws
method call temporarly from HelloClient.java. I can now build the
client with "ant build" and I recieve no complaints.
However when I go to execute the beast with "ant run" I get a java
NoClassDefError for dynamicproxy.HW5IF. The error is somewhere in
the "getPort" method because when I comment it out everything
works. Obviously HW5IF is not being generated at runtime.
However, the end-point, service name, uri, and portname all match
the WSDL of the webservice. Below is my code & WSDL. Any advice is
more than welcome.

Answer 1

I'm using the ant run/build scripts that came with the tutorial, so ant should be running wscompile for me (I think).
I'm using the jwsdp-1.2 with the jws 1.2 tutorial.
Here are the exact steps I follow:
1) make a copy of jwstutorial12/examples/jaxrpc/dynamicproxy called HW5dynamicproxy.
2) change the endpoint.address in the build.properties file to http://localhost:8080/HW5/HW5
     (I've tested this endpoint and it works so my webservice is definitely there).
3)change the wsdl location in config-wsdl.xml to http://localhost:8080/HW5/HW5
4)go to src/HelloClient.java and change all references of "dynamicproxy.HelloIF" to "dynamicproxy.HW5IF"
     (This is my service interface.)
5)in the same file change serviceName to "MyHW5Service"
6)and change portName to "HW5IFPort"
7)comment out the System.out.println(..) temporarily because my ws methods are different.
8) execute "ant build" - nothing unusual.
9)execute "ant run" :
Buildfile: build.xml
run-client:
[java] UrlString = http://localhost:8080/HW5/HW5?WSDL
[java] java.lang.NoClassDefFoundError: dynamicproxy.HW5IF
[java]      at dynamicproxy.HelloClient.class$(Unknown Source)
[java]      at dynamicproxy.HelloClient.main(Unknown Source)
[java] Exception in thread "main"
run:
BUILD SUCCESSFUL
Total time: 3 seconds
Heres a printout of my webservice endpoint info:
