hi.
i'm using tomcat_3.2.1 under win, linux and sun solaris
always the same problem.
when i run my application, jar files placed in WEB-INF/lib are not loaded by classloader (null pointer exceptions)
if i add them to tomcat_home/lib or add to the classpath explicitly each one of them it works.
but this are not suitable solutions for me because i want to place them ONLY in WEB-INF/lib not changhing the classpath
here a detail of error:
