Xalan 2.5, Xerces 2.3 and JDK1.4.1

Hello.

I wonder if anyone has any experience of this problem?

I am using JDK1.4.1 and Xalan 2.5.D11. The xalan.jar is in the endorsed directory for Tomcat and I have tested the version number by printing it to the screen. I am confused as to why I get the "NoClassDefFoundError" since the xalan.jar is accessible. Am I getting a combination of the later Xalan version and the version included in JDK1.4?

The webapp is hosted by jsp-servlets.net, so I do not have full access to the Tomcat config.

Any ideas would be appreciated!

I have been checking the versions of Xalan, Xerces and JDK that I am using. My app is seeing the new Xalan version OK. Another important difference is that I compile on Win98 and run on Linux.

thank you.

This seems to be a sandbox problem. Some class tries to read a ressource but is not allowed to do so. I think, I can give a roundabout though not a solution:
Include in a .jav.policy- file in your home directory lines as follows:

grant codeBase "http://SERVER_ADDRESS_WHERE_THE APPLETCLASS_IS STORED" {
permission java.io.FilePermission "C:\\Program Files\\Java\\j2re1.4.2_02\\lib\\-", "read";
};


(Change the path to the location of your Java-JRE)

This helps with my applet, though I would like to get a solution without a java-policy.

Thanks for helping.

What I had to do was have permission granted so that my application could read the Xalan.jar file. It was not enough to simply "access" it to run the classes, rather it had to be able to read a .properties file within the jar.
