Bug 126308

Please attach full IDE message log and the steps to reproduce.
The stack trace does not have any visualweb code.

Were you referencing java.sun.com in your application somewhere?

Apparently it is trying to resolve tld namespace URI or schema in:

org.netbeans.modules.visualweb.jsfsupport.container.JsfTagSupport.addTaglibFacesConfigMapEntry

Winston, should we be using some URI mapper hrough layer files?

Here is the full stacktrace:

I need to add the off-line entity resolver to document builder in JsfTagSupport.

Ok, even after setting the DocumentFactoryBuilder.setValidating(false), DocumentBuilder seems try to resolve the
namespace URI entity.

So fix this bug explicitly setting an Empty EntityResolver resolver. It may seem odd to skip validation. But accorsing
to me, when a component set is added to IDE, the faces-config.xml must be well tested and proved.

In my opinion, skipping the validation overhead would improve the performance, assuming the faces-config.xml is well tested.

Now explicitly setting an Empty EntityResolver resolver to skip validation.

Reopening - reproduced in NetBeans IDE Dev (Build 090127)
