Getting the include-prelude to work in jsp editor [message #488935]

Hello, I am trying to use include-prelude in my web.xml to include a jsp file that has the includes for the taglibs in it. Problem is all of my jsp's have errors that say "Unknown tag". I am using a Dynamic Web project, the top level jsp with the include finds the tags ok.

Can you post the parts of the jsp-config section setting up the
preludes, the workspace paths to the JSP and prelude fragment files,
as well as which version of WTP you're using? One of the earlier
releases limited you to a single prelude fragment per JSP file. Are
you trying to match preludes with fragments that are included by a
JSP that themselves wouldn't match the url-pattern for that group?

Ok here it goes, I created a sample app to isolate things. I am using the latest version of Eclipse/Webtools, I just pulled it down yesterday to make sure I had the latest.

Here is the web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>test</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>

<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<page-encoding>UTF-8</page-encoding>
<scripting-invalid>true</scripting-invalid>
<include-prelude>/includes/prelude.jspf</include-prelude>
</jsp-property-group>
</jsp-config>
</web-app>

now one level above the WEB-INF I have a folder called includes with 3 files in it:
taglibs.jspf

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

prelude.jspf

<%@ include file="/includes/taglibs.jspf" %>
<c:set var="testTrue" value="${true}" scope="request"/>

and now
header.jsp
<c:set var="testTrue" value="${true}" scope="request"/>

the jsp editor is fine with the prelude.jspf, no warnings. With header.jsp it is reporting "Unknown tag (c:set)"

If I put the code from the taglib.jspf into the prelude.jspf then all is fine. Thanks for the help.

Jon,
The use case of an include directive in a fragment included as a
prelude is explicitly disallowed in WTP, but as I see that Tomcat
allows it, can you open a bug report for us to hopefully fix it in
WTP 3.2?
