Running in tomcat5 but not in tomcat 6

[Arvind Subramanian]

I configured same project to run in both tomcat5.5 and tomcat6, which was previously runnning in tomcat5.5 alone. Everything is working fine in tom 6 except by struct tag. i used <html:rewrite page='/XXXX.js'/> in various places where i get exception in tomcat.

There's another thread regarding this exact same error (with a "plsssss" or something similarly ridiculous in the subject line)--I think someone posted a link to an answer; see if that helps!

[Arvind Subramanian]

[Joe Ess]

Please do not post the same question more than once.
