Debugging Custom Generators & Transformers in VAJ
I apologize for posting this over here, but after some thought
it seemed like the folks who read this list might be better equipped to
answer this.
I work for company that is developing a series of custom
generators, transformers, and serializers. Since we are new (relatively
speaking) to Cocoon we would like to able to debug our custom Cocoon 2
code using a debugger.
We use Visual Age for Java, and we have gotten the latest build
of Tomcat to run inside of VAJ, but we are not able to make Beta 2 of
Cocoon 2 work in this configuration.
The cocoon.log file has a lot of information in it, but the
error can be summed up by saying that for some reason Cocoon is unable
to locate the proper component handler to read its own sitemap.
Has anyone had any experience with running Cocoon 2 under Tomcat
inside of VAJ, and if so - what do we need to do to make this work
properly?
I have enclosed the output from the relevant section of the log
(the tail end) after my signature. Thank you very much for your
assistance.
Sincerely,

Re: Debugging Custom Generators & Transformers in VAJ
Posted by "Stuart Roebuck (BlueYonder)" <st...@mac.com>.
I've been doing quite a bit of debugging of Cocoon 2 under Tomcat 4.0b
using jdb and jswat in the last week or so. One problem I ran across
early on was that if I had two or more cocoon based contexts in Tomcat,
debugging only seemed to be able to 'see' one of them, and this invariably
was the cocoon example that came with Cocoon rather than the code I wanted
to debug. So I removed the example Cocoon sitemap during debugging and
all was well.
Stuart.
