Servlets Not Working on 8.5 Test Server

Servlets that we copied from a 7.0.2FP1 server will not work on a 8.5 server.

We have been running several servlets that produce charts in a web application on a 7.0.2FP2 server.

We set up an 8.5 test server and copied the application and the servlets over to the 8.5 environment. Here’s what we get we the servlet is called: HTTP JVM: java.lang.NoClassDefFoundError:org.jfree.text.TextUtilities(initialization failure): org.jfree.text.TextUtilities(initialization failure):

Any ideas why the same exact servlet that works on a 7.0.2 server WON’T work on an 8.5 server?

Thanks
