Nested .tag files problem

[Mark Thomsit]

Hi,

I am trying to create nested tag files but even though they both work in isolation (commenting out the parent or child) they fail when one is nested inside the other.

The tags are packaged in a jar inside my WEB-INF/lib. The jar includes two tag files in META-INF/tags/form and a tld in the META-INF directory. The tags are called actions.tag (parent) and action.tag (child) and are as follows:

actions.tag

<%@ tag body-content="scriptless" %>
<%@ attribute name="prefix" required="true" %>
<%@ attribute name="type" required="true" %>
<div class="${type}actions clearfix" id="${prefix}actions">
<ul class="horiznavlist">
<jsp:doBody />
</ul>
</div>

action.tag

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<%@ attribute name="messages" required="true" %>
<%@ attribute name="key" required="true" %>
 
<fmt:setBundle basename="${messages}" var="actionMessages" />
<li id="${prefix}${fn:replace(key, '.','')}">
<input type="submit" name="${key}" value="<fmt:message key="${key}" bundle="${actionMessages}" />" class="button"/>
</li>

form.tld

<?xml version="1.0" encoding="UTF-8" ?>
 
<taglib 
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee web-jsptaglibrary_2_0.xsd"
version="2.0">
  
<description>Tag files for forms</description>
<tlib-version>1.0</tlib-version>
<short-name>f</short-name>
<uri>http://www.myco.com/framework/ui/form</uri>
<tag-file>
<name>action</name>
<path>/META-INF/tags/form/action.tag</path>
</tag-file>
<tag-file>
<name>actions</name>
<path>/META-INF/tags/form/actions.tag</path>
</tag-file>
</taglib>

page.jsp

<%@ taglib uri="http://www.myco.com/framework/ui/form" prefix="f"%>
 
...
 
<f:actions type="global" prefix="top">
    <f:action key="application.label.action.save" messages="messages.ApplicationResources" />
</f:actions>

Using both tags together gives this exception which gives me no real clues.

Can anyone see what might be wrong?

Thanks in advance

The message doesn't seem to match your JSP code much, does it?

I've moved this over to our Websphere forum where those more savvy regarding WS quirks may be able to help.

As a follow up, I've tested with an extremely simple example which uses no attributes and get the same problem.

outer tag - testbody.tag

<%@ tag body-content="scriptless" %>
<div id="testwrapper">
<jsp :mrgreen: oBody />
</div>

inner tag - another.tag

<%@ tag body-content="empty" %>
<div id="inner"></div>

calling jsp - new.jsp

<%@ taglib tagdir="/WEB-INF/tags" prefix="f" %>
...
<f:testbody>
    <f:another />
</f:testbody>

error

sorry - part of the JSP code was missed:

<%@ taglib tagdir="/WEB-INF/tags" prefix="f" %>
...
<f:testbody>
  <f:another />
</f:testbody>
