Hi all,

I have this problem since a long time now and still didn't find a solution.
That's why I come here.

I have one web-app, "LeHallWeb", an eclipse project in WTP Eclipse,
it's running fine on my Tomcat instance of my Tomcat server.
The JSP are correctly converted to HTML.

But I can't make an other project, "JSP01", to run on my server.
I also tried to run it on an other Tomcat instance, on the same server,
it just won't work : the JSP's aren't displaying anything...

I added "LeHallWeb" project to "Tomcat v5.5 Server @ localhost"
I added "JSP01" project to "Tomcat v5.5 Server @ localhost (2)"

It seems that I can only run one web-app on my tomlcat server.

If u have any ideas, any help on how I can debug this,
I would appreciate any help !

Thank u.

I can notice this when I start the server that is assigned to JSP01 (the
one that not work) :

INFO: validateJarFile(D:\Informatique\Projets\LeHall\WorkSpace
LeHall\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\w ebapps\JSP01\WEB-INF\lib\javax.servlet.jar)
- jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class:
javax/servlet/Servlet.class

There are certain classes, identified by their package, that the server
supplies which webapps aren't allowed to override. If such classes are
found in a jar in WEB-INF/lib, Tomcat deals with this by ignoring the
offending jar. Obviously, javax.servlet is one of those packages.
Assuming javax.servlet.jar only contained javax.servlet classes, this
shouldn't by itself cause your webapp to fail.

I would start by removing this jar from the webapp since it is always
wrong to have a jar like this in WEB-INF/lib. If there are still
problems, provide more detail about what exactly is going wrong.

Cheers,
Larry
