Is this a bug?

Tue, 18 Feb 2003 01:27:59 -0800

Hello!
 
I have a problem with a JSP generator, and after many attempts, now I think that there could be a bug.
So I need your help!
I use Cocoon 2.0.4 with Tomcat 4.1.18, on a server that runs Linux RedHat 8.
Here I write my simple test code:
 
The jsp (named prova.jsp) generates a small xml data, and reads a request parameter from the http request.
 
<%@ page contentType="text/xml"%><?xml version="1.0"?>
<document>
  <parametro><%=request.getParameter("name")%></parametro>
</document>
 
This simple jsp was included as generator in my sitemap:
 
<?xml version="1.0"?>
<map:sitemap xmlns:map="http://apache.org/cocoon/sitemap/1.0">
<map:components>
   <map:generators default="file"/>
   <map:transformers default="xslt"/>
   <map:readers default="resource"/>
   <map:serializers default="html"/>
   <map:selectors default="browser"/>
   <map:matchers default="wildcard"/>
</map:components>
<map:pipelines>
   <map:pipeline>
     <map:match pattern="prova.jsp">
       <map:act type="request">
         <map:parameter name="parameters" value="true"/>
         <map:generate type="jsp" src="" mime-type="text/xml"/>
         <map:serialize type="xml"/>
       </map:act>
     </map:match>
   </map:pipeline>
</map:pipelines>
</map:sitemap>
<!-- end of file -->
 
I think there is nothing wrong in this sitemap!
 
I get the exception:
 

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.
