Jsp malefunctioning

I'm using Jigsaw 2.1.1 under Linux Caldera 2.3, and i need Jsp environment.
I've installed all the file needed (servlet_2.1.jar and gnujsp10.jar) and configured my server as described in install.jigsaw 
but i have a little problem in my environment.
After i start Jigsaw 


============= JIGSAW SCREEN ===========================
loading properties from: /opt/Jigsaw/Jigsaw/config/server.props
*** salvaging resource manager state...
*** resource store state salvaged, using: 1
*** Warning : JigAdmin[2.1.1]: no logger specified, not logging.

GNUJSP: Detected JSDK version 2.1

and i call my jsp file index.jsp


=========== INDEX.JSP======================================= 
<%@ page isErrorPage="true" %> 
 
<!-- This error page demonstrates a JSP ErrorPage used for 
     catching exceptions thrown in other JSP pages, it is 
     used by the ThrowException.jsp page --> 
 
<html>

<body bgcolor=#ffffff> 
 
<font face="Helvetica"> 
 
<h2><font color=#DB1260>JSP Error Page</font></h2> 
 
<p> An exception was thrown: <b> <%= exception %> 
 
<p> With the following stack trace:

    ByteArrayOutputStream ostr = new ByteArrayOutputStream(); 
    exception.printStackTrace(new PrintStream(ostr)); 
    out.print(ostr); 
%> 
</pre> 
 
<p> 
<hr width=80%> 
 
</body> 
</html> 
 
 =========== END INDEX.JSP=======================================
