I am having a problem when trying to deploy a WAR or EAR which uses the BeanShell engine. I get a variety of errors, most notably IllegalAccessException errors which indicate that some classloader is trying to load BeanShell engine classes from two different JARs. The only solution I have come up with for the moment is to remove the BeanShell JAR from the server/default/lib directory, however this seems like an ugly hack. Is there a more appropriate way to fix this so that I can use BeanShell in my WARs and EARs? Thanks.
