RE: pre-compiling jsp files with maven

["Sonnathi, Venkat" <Ve...@contractor.thomson.com>]

Hi,

I am trying to pre-compile jsp files using maven as per the following link:

http://wiki.codehaus.org/maven/CreatingWebApplications#head-2b0c6db33bd58f8f
93de3b6ff49263e574447731

However I get a class cast exception. Any suggestions?
