Upgrade to tomcat 4.0.4 - 4.0.6, then you can put the jaxb-rt.jar into the WEB-INF/lib directory. I think 4.0.3 has some class loader issues with packages that start with java and javax in the WEB-INF/lib folders
This solved the problem for us.

We are successfully using shared jar files accross applications by placing them in the $TOMCAT_HOME/shared/lib directory. This will help to not use the common/lib directory. Hope it helps.

Hi all I have some code that uses JAXB that works fine in a standalone app with the jars I expect it to need. When I put the same code in a webapp I got a couple of problems initialising the Sevlet (see log file below). I managed to get rid of one problem (javax.xml.bind.JAXBContext) by putting a copy of jaxb-api.jar in /common/lib (before it was only in app/WEB-INF/lib). The second problem was solved by copying a xerces.jar into my app/WEB-INF/lib directory (as far as I can tell my standalone app did not need org.w3c.dom.ls.DocumentLS at all). Can anone shed more light on this? Specifically I would be interested in any ways to avoid using the /common/lib directory. I'm using Tomcat 4.0.3, JAXB 1.0 beta (currently the latest version), and the magic Xerces that came to the rescue was 1.4.4. Despite the name of my webapp I am NOT intent on spamming!
