JSF composite components in JAR not recognised in NetBeans

问题

I have added a common JAR to my project. The jar looks something like...

CommonWeb.jar
 |-- META-INF
 |    |-- resources
 |    |    `-- common
 |    |         |-- css
 |    |         |    `-- my.css
 |    |         |-- js
 |    |         |    `-- my.js
 |    |         |-- images
 |    |         |    `-- my.png
 |    |         |-- components
 |    |         |    `-- mycomposite.xhtml
 |    |         `-- templates
 |    |              `-- mytemplate.xhtml
 |    |-- faces-config.xml
 |    `-- MANIFEST.MF
 :

Everything is working except that Netbeans will not recognise my composite component. The page trying to use the component looks something like this...

<ui:composition template="/resources/common/templates/mytemplate.xhtml"
                xmlns="http://www.w3.org/1999/xhtml"
                xmlns:h="http://java.sun.com/jsf/html"
                xmlns:ui="http://java.sun.com/jsf/facelets"
                xmlns:p="http://primefaces.org/ui"
                xmlns:f="http://java.sun.com/jsf/core"
                xmlns:cmn="http://java.sun.com/jsf/composite/common/components">

    <ui:define name="content">
        ...
        <cmn:mycomposite ... />
        ...
    </ui:define>
</ui:composition>

The project will compile and run, no worries. But the IDE gives me red squiggly lines on <cmn:mycomposite ... /> and does not auto-complete, etc. It will all work fine if I copy the component into the project's own resources folder, so it seems netbeans just isn't looking to the jar.

There are quite a few questions around with similar problems, eg:

JSF Composite Component into JAR in NetBeans
JSF Composite Component Netbeans
Composite components in an external JAR are not recognized in Netbeans

...but there are no satisfactory solutions or workarounds.

Also there have been a few netbeans bug reports on the matter but these all seem to be 'fixed'

Is there some configuration that I'm missing? Has anyone actually managed to get this working with the latest version of NetBeans (NetBeans 7.4 Patch 2 at time of writing)? Has anyone found a work-around that actually works?

UPDATE:

This problem continues to occur in NetBeans 8

回答1:

This issue is an IDE only issue and continues in version 8.1. It stems from the bug identified in Netbeans bugzilla - specifically in the "JSF Editor for XHTML" module (org.netbeans.modules.web.jsf.editor)

I resolved the issue by downloading the version 8.1 source files for Netbeans and applying the suggested patch myself. I'm guessing it's a similar issue in earlier versions but I didn't check this.

To download and compile Netbeans you can follow the "How To" in here

Changes in summary:

CompositeComponentModel.java line 296 changed to:

if (parent != null && parent.getName().equalsIgnoreCase("META-INF")) { //NOI18N

JsfBinaryIndexer.java line 74 changed to:

namePattern = ".*\\.tld|.*\\.taglib\\.xml|.*\\.xhtml",

Indexer version incremented on line 81 changed to:

static final int INDEXER_VERSION = 11; //NOI18N

Given that the bug is being tracked hopefully it makes it into the next release.
