I think that probably my problem will be the classpath. I know how to change the classpath,
but i don't know wich is the order of the fop jars in orion and their relation with the orion's jars.
To configure tomcat i did the next steps:
"i put I put xerces-1.2.3.jar, xalan-2.0.0.jar at the beginning of tomcat classpath and
deleted the jaxp.jar, parser.jar "
Any url to get information will be well received.
