Hi,
I have successfully used the CastorTransformer. I am working on a new
version that can be used to marshal and unmarshal, and doesn't use
deprecated classes/code anymore. It's not finished, but I allready use it in
a project.
I have it working in the latest CVS version of Cocoon, but it will probably
also work with 2.03. If you'r interessted, I can mail a copy of the latest
source.
You'r problem sounds like a classpath/version issue, otherwise I can also
find no explanation for the NoSuchMethodError
HTH,
Michael

Subject: Re: Cocoon 2.0.3 and CastorTransformer
Thanks, Vadim. Now, please find below the stack trace (just the root
cause) from
Catalina's app specific log file. Looking at line 94 of
CastorTransformer.java
(from the scratchpad of the Cocoon 2.0.3 source dist) I can see that it
fails on
the line marked with --> <---, but simply woul dnot know enough to tell
why ?
Is anybody actually using the CastorTransformer sucessfully ?
