Hi,
We
have made sure that only one Xerces jar is loaded by one class loader
only. Problem still persists.
Any
clue?
Thanks
Upinder..

Hi,
I don't think that the version numbers of Castor/Xerces are an issue in your case. I'd rather investigate classloader issues, where e.g different versions of Xerces are loaded by different classloaders. In other words, make sure that Xerces is loaded by one and one classloader only.

XML MARSHALLING ISSUE
Hi,
There is a typical problem being faced by us while marshalling of XML files.
We were using Castor - castor-0.9.4.1.jar & xerces-J_1.4.0 jar initially.
Till now we were using this version of Castor to only read existing XML files (having some business rule data) and there was no problem. Recently we developed another interface in our application to modify the
data in these XML files and then save the XML files using Castor. This is where we started getting the IncompatibleClassChangeError.
Even we tried with latest castor-0.9.5.3 but still we are facing the same problem.
We have tried with all possible combinations of castor and xerces versions.
Problem Details:
java.lang.IncompatibleClassChangeError

Can anybody suggest or knows what combination of castor & xerces versions one should use if this is really a version issue.
Thanks
