XSL/XHTML IDE

Hi,

I am looking for an existing XSL/Java IDE
or Eclipse plug-in.

My requirements are not high:
- visual editing (and better debugging) of XSL/XHTML forms,
- XML/XSLT support;
- some integration with JBoss [3.0.7];
- support Java [JDK 1.4+], including debugging.
- (maybe) support of Cocoon 2.0.4;
(Editing Cocoon sitemaps is very nice but not required.
I am working on enhancing existing Cocoon project,
not doing new projects).

I use Eclipse [with MyEclipse] and XMLSpy.
Maybe XMLSpy plug-in for Eclipse is the answer ?

But I don't see it showing HTML page out of XSL form at all.


Thank you in advance,
Oleg.
