Re: FormBean error using Struts 1.1 and Tomcat 5
Forget it, guys, I called an exorsist and a vodoo-specialist, who told
me to install Tomcat 5.0.16, and now it works.

Hi,

The strange thing is, I'm not working on the user interface at the

Re: FormBean error using Struts 1.1 and Tomcat 5
Couple of questions:
Are the Struts and supporting JAR files installed in your app's WEB-INF/lib or
someplace else like $CATALINA_HOME/common/lib?
Are you intentionally using JSTL 1.0? With TC 5, you probably want JSTL 1.1.
How are you doing your deployment/update? For example, are you copying WAR files
or using TC Ant tasks or...?

Anyone got any ideas ?
