Hello and thanks in advance for any help. I am trying to deploy a war (that worked with Tomcat 4.1) on SAP Web Application Server.

In this war I have a JSP that says

<?xml version="1.0" encoding="UTF-8"?>

<jsp:root version="1.2" xmlns:jsp="http://java.sun.com/products/JSP/Page"

xmlns:c="http://java.sun.com/jstl/core"

xmlns:trx="http://www.highdeal.com/taglib">

<jsp:directive.include file="jspf/doctype.jspf"/>

<html>

<jsp:directive.include file="jspf/Imports.jspf"/>

<jsp:include page="include/Variables.jsp" flush="true" />

<head>

<title><c:out value="$"/></title>

<jsp:directive.include file="jspf/Style.jspf"/>

</head>

(...)

In my web.xml, I have:

<taglib>

<taglib-uri>http://www.highdeal.com/taglib</taglib-uri>

<taglib-location>WEB-INF/trx.tld</taglib-location>

</taglib>

<taglib>

<taglib-uri>http://java.sun.com/jstl/core</taglib-uri>

<taglib-location>WEB-INF/c.tld</taglib-location>

</taglib>

I am becoming crazy because of the exception I keep having in the logfile:

#1.5#0013CEDA9E4F00380000000800000DDC00040F1A970A7F6A#1142506784439#com.sap.engine.services.servlets_jsp.server.jsp.JSPParser#sap.com/csrui.war#com.sap.engine.services.servlets_jsp.server.jsp.JSPParser#Guest#2####f9b076e0b4db11da96df0013ceda9e4f#SAPEngine_Application_Thread[impl:3]_7##0#0#Error#1#/System/Server#Plain###Runtime error in compiling of the JSP file <D:/usr/sap/J2E/JC00/j2ee/cluster/server0/apps/sap.com/csrui.war/servlet_jsp/csrui/root/WEB-INF/jsp/Logon.jsp> !

Hi Tangi,

A small mistake in your web.xml

<taglib>

<taglib-uri>http://www.highdeal.com/taglib</taglib-uri>

<taglib-location><b>/</b>WEB-INF/trx.tld</taglib-location>

</taglib>

<taglib>

<taglib-uri>http://java.sun.com/jstl/core</taglib-uri>

<taglib-location><b>/</b>WEB-INF/c.tld</taglib-location>

</taglib>

You have missed a / before WEB-INF.

Also, the order of entries in web.xml matters. Refer <a href="http://www.pchighway.com/helpdesk/index.php?page=index_v2&id=1694&c=135">here</a> for more info about JSTL.

Hope this solve your problem.

Regards,

Uma

Thanks again for your help, but the pb is still there. I tried several things, and the problem doesn't seem to be in the location of the tld files (to test, i put a wrong entry, and it put a File not found exception). The pb really seems to be about namespace declaration. Do I have to declare them elsewhere? Any other clue?

Hi Tangi,

There are few steps to follow for installing JSTL support.

1. Download the JSTL archive (binaries not source) from the Jakarta Website. Unzip/untar the file.

2. Add the neccesary jar files to your Web Module Project.

3. Copy the .tld files to the WEB-INF directory in your Web Module.

4. In your jsp page, before head elemnet add <%@ taglib prefix="c" uri=http://java.sun.com/jstl/core %>

5. JSTL requires a JSP 1.2 Web container. ( Tomcat 4.1 supports this).

Hope this helps.

Regards,

Uma

Thanks Uma, but this did not make any improvement to the situation. I still have this error about the namespace that is not mapped to a namespace. Somebody knows if I should declare namespace in other places than the jsp:root tag using the xlmns attribute?

Tangi
