Hi,
First let me thank anyhow who will take the time to read this message, let
alone offer any advise/solutions.


So here is the deal, I been using eclipse for years now, and of course
love it. It was a bit of transition, as was traditionally more of a
multiple terminals of vi kinda guy... Being able to use vi within the
eclipse editor was the turning point for me I think. Anyhow, I have been
trying to use WTP for a while now, but each time I end up giving up. Now I
really can't give up on it. I have read through the webtools platform
book, spent countless hours searching on the web, and annoyed people in
IRC #eclipse.

Here is what I do:

I create a dynamic web project
I create a WSDL
I use the top-down approach to generate service code from the WSDL
I get through to almost to the end of the wizard, but get a
"invocationTargeException" and then am kinda stuck. (I will attach the
stack trace at the end)


Now the whole processes has actually worked before, but then after some
what appears to be random amount of time, I start getting this
invocationTargetException again. It was quite nice at this point, I
develop my service and the service is synched with my local tomcat server,
etc... Then beyond the exception issues (which of course are only relevant
when I need to update the WSDL), all the sudden my service is no longer
being built or deployed to the my local Tomcat.

Ok so now for future projects I just try to avoid the WTP code gen
processes altogether. I manually generate the code using the axis2 tool
wsdl2java. However, I can't get the dang service to be built and then
deployed to the local tomcat server. Its as if I don't use the built in
code generation wizard, the project doesn't know there is a service being
built.


So my question is, is there a way to use WTP/Eclipse to build web services
without going through the generation wizard. Is there some config file I
can update with information about my web service that eclipse will then
pick up on? I have no problem just going to the command line and
generating the code, using an ant file to do the compiling etc. I am just
looking for how people do web service development in eclipse if not using
the generation wizard.

Now if someone can help me solve the invocationTargetException or the
random loss of "autobuild" that would be great as well.

I am using Ganymede, Version 3.4.2
WTP version 3.0.4

On OSX Leopard

Below is an example WSDL file and stack trace

Jeff, you can always create a Ant build script to generate your service
from the WSDL. In some ways it gives you more flexibility, but you
have to do more setup yourself.

If you search the web you'll find plenty of articles explaining how to
generate through Ant.
