Strange Problem
Hi,
i started a new project and trying to use Spring-WS. Yeah. :)
But i hava a strange problem. I'm using JAXB2.
My web service is called, but at the marshalling i get an error, which i doesn't understand. My testclient get a "500, Internal Server Error" back.
I have installed a logging and validating interceptor and a endpointExceptionResolver.
That's my log4j configuration:
Code:
log4j.rootLogger=ON,FileAppender
log4j.logger.de.cas=DEBUG
log4j.logger.javax.xml.bind=DEBUG
log4j.category.org.springframework=DEBUG
log4j.category.org.acegisecurity=DEBUG
and i get this logging messages.
Code:
[...]

As you can see, my web service is working fine ("create web service completed" log message). I also added an exception handling around my complete web service code. But there is no exception.
Any idea what's wrong?
It's possible that it is a JAXB2 problem. Any idea how to log messages from it? I looked in the jaxb2 docs and forum, but found no answer.
Cheers,
Ingo

The problem was that Spring-WS's exception handlers tried to create a response message when a response was already there. That used to throw an exception, but no longer does: it has been fixed in subversion. I'll do a snapshot release later today which contains the fix and all others I've done this week.

Wow, that was fast.
Thank you. :)
I'll wait then for the snapshot release.
Ingo
