Question

I am working on porting a legacy web app to JBOSS AS7. The code works fine in Tomcat 6 or JBOSS 5. The app uses struts-1.2.9 and we also have some custom taglib defined which are giving me problems.

I have a mainScripts.jsp file that defines a taglib

<%@ taglib uri="/WEB-INF/lib/abtaglib.tld" prefix="abtag" %>

The /WEB-INF/web.xml files includes the following. Not sure if this is needed!?

<taglib>
    <taglib-uri>abtags</taglib-uri>
    <taglib-location>/WEB-INF/lib/abtaglib.tld</taglib-location>
</taglib>

When I access this page in JBOSS AS7, I get the following error. It seems that the jboss web modules cannot access the files in my war file. How can I fix this?

Was it helpful?

Solution

I found a solution. It seems that Jasper, which is in a JBOSS module (jbossweb-7.2.0.Final-redhat-1.jar), is unable to access my tld file located in /WEB-INF/lib/. The same code works in JBOSS 5, Websphere 6 and in any version of Tomcat. I think this is a class loading issue. When I moved my tld file inside a /META-INF folder within a jar file it started working. I did not need the taglib reference in the web.xml anymore, because the tld file is automatically picked up from the jar file /META-INF folder. Here's the final code:

Declare taglib in jsp:

<%@ taglib uri="http://mycompany/abtags" prefix="abtag" %>

packaged tld file insde a jar:

/WEB-INF/lib/XYZ.jar

XYZ.jar content:

/META-INF/abtaglib.tld
/META-INF/MANIFEST.MF

abtaglib.tld content

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib
  PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
  "http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">
<taglib>
    <tlib-version>1.0</tlib-version>
    <jsp-version>1.1</jsp-version>
    <short-name>abtag</short-name>
    <uri>http://mycompany/abtags</uri>
    <display-name>XYZ Tag</display-name>
...

OTHER TIPS

I was having same problem with Jboss 8(Wildfly 8). Copied all taglib "*.tld" files into META_INF folder, worked for me.

You should use the URI defined in your tld file and, yes, define it's location in your web.xml. For example :

<%@ taglib uri="http://mycompany/jsp/abtablib" prefix="abtag" %>

If you're using a standard taglib, just put the jar in your classpath and use the correct URI. Here is an example with the core jstl taglib (put jstl-1.2.jar in your classpath) :

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
