Hi,
I am experiencing servelet exception in one of the JSP page when
using
Tomcat 4.0 beta with JDK 1.3. Since I am not familiar with the
Tomcat
configuration,
I place my jsp pages under a sub-directory, named ses, created
under
webapps/examples/jsp and startup the tomcat with the associated
class
files
in two different manners:
1) first trial, I placed the tar files in
webapps/examples/WEB-INF/lib
=09
2) second trial, the classes are expanded in=20
webapps/examples/WEB-INF/classes/ses=20
In each of the above cases, I got this Servlet Exception.=20
Any suggestion is greatly appreciated.
Thanks
Here are the exception messages for=20
