Unable to translate jsp with struts-html taglib

[Rade Treci]

Hi everyone!
First I hope that the question is within the standards of the forum.

As for the problem per se,

I'm using Tomcat6.0.18, Eclipse3.4, jdk1.5. It seems tomcat cannot interpret correctly the html struts tag, although it seems that I have set the <taglib-location> pointing to the correct uri.

In my web.xml:

    <taglib>
      <taglib-uri>struts-html</taglib-uri>
      <taglib-location>/WEB-INF/tlds/struts-html.tld</taglib-location>
    </taglib>

In my whatever.jsp:

<%@ page contentType="text/html;charset=UTF-8"%>
<%@ taglib uri="struts-html" prefix="html"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-tiles" prefix="tiles"%>
 
....
 
line 23: <html:form action="<%= request.getAttribute(WebConst.ACTION_NAME)%>" onsubmit="return doEnter();">
 
....

And my StackTrace!

org.apache.catalina.core.ApplicationDispatcher invoke
SEVERE: Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: Unable to compile class for JSP:

In the jsp I tried already moving the taglib to the first line: DID NOT WORK
Changed the uri in the taglib to, http://struts.apache.org/tags-html : DID NOT WORK
Tried pointing the uri directly to the tld file: DID NOT WORK

By the way also <html:radio> tag seems to have problems getting translated, so I suppose that all html:XXXX tags will end up the same. At the moment I haven't tested other struts taglibs (like logic or bean) but I guess the same would happen...

Right now I have no more ideas and any pointer would be deeply appreciated.

Thank you,

By looking at the error, I think the error is because request.getAttribute return Object while it is expecting a String there. Use a type cast or a toString call like this...

<html:form action="<%= (String)request.getAttribute(WebConst.ACTION_NAME)%>" onsubmit="return doEnter();"> 

<html:form action="<%= request.getAttribute(WebConst.ACTION_NAME).toString()%>" onsubmit="return doEnter();">

I forgot to mention that this works using JDeveloper and OC4J app server (need to make it work in Eclipse and Tomcat). I would like to make it work with minimum code changes (hopefully none, because there is a LOT to change). I just hope that this is a config problem.

Please be sure to ask Struts questions in the Struts forum. I have moved this post there for you.

OK thanks
