possible causes of IncompatibleClassChangeError

I am using axis to provide a soap service within another application.  
It does this by calling an instance of org.mortbay.jetty.Server and 
handing it the war file.

On my desktop (WinXPSP2, jdk1.5.0_01) this works fine and a test client 
is able to use the service.

On a Linux system (trustix2.1) the same setup works as well (still using 
winxp to run the client).

On a second (virtually identical) Linux box it fails with the following 
exception.   I've done my best to ensure that all the dependencies are 
the same on both linux boxes (including saaj which I've seen other 
postings about).   I'm relatively new to both SOAP and Axis:

Yeah, I saw that in the archives.  However the only versions of axis and 
saaj jars present on any of these test systems is 1.2 (that includes in 
lib dirs, war files etc etc).   Could this also be causes by a xerces 
conflict?

Out-of-date saaj.jar.  Check your class path to make sure that the 
saaj.jar found is the one which came with your axis tree.

See the archives of this mailing list for more info.
