Pretty basic, but can you locate this class in the classpath at precompilation time !!!
Print out your classpath being used at precompilation stage & then check this class file in those jars. -thnx. -----Original Message----- From: DeJong, Jonathan [mailto:[EMAIL PROTECTED] Sent: 14 October 2005 19:21 To: users@tomcat.apache.org Subject: Precompilling struts-el tags with Jasper2 Hello, I've been battling this problem for a couple days now. I've googled it, and have seen it posted other places, but with no solution (that I've found). I also can't find anything in bugzilla (does not mean it's not there, just means I can't find it). If anyone has experienced this and knows of a fix/solution/workaround, I would greatly appreciate it. The problem appears when precompiling a jsp that uses the struts-el tags using Jasper2. I've attached the stack trace below. I walked through the struts and struts-el code and noticed that basically, what's happening, is a class uses ClassLoader to attempt to load a class in it's own package and jar file. This throws a java.lang.ClassNotFoundException, which of course makes no sense, since they're at the same location. The error occurs only during precompilation, when the jsp code is being translated into java code, before any actual compilation. The reason I think this is an issue with Jasper/Tomcat is that in a previous project, I had the same problem using Weblogic, and gave up on precompilation, which was fine then. BEA has come out with a fix in SP4 (which makes me think it's a compiler problem, not a struts-el problem). However, my current project uses JBoss, and precompilation is an absolute must. Thanks in advance!
