[wtp-dev] JSP validation and runtime provided Tag Libraries

[David Klein <kleind@xxxxxxxxxx>]

I have noticed that tag libraries that
are copied into a web app's WEB-INF/lib directory are recognized by the
JSP validator, but tag libraries that are not in WEB-INF/lib, but instead
on the project's classpath are not recognized.  By "not recognized"
I mean a JSP file using tags from the library has these tags flagged with
an "Unknown tag" error.  If it is perhaps a performance
issue to have to search all libraries on a project's classpath for TLD
files, is there (or could there be) a means of registering such tag libraries
such that they can be found by the JSP validator?  A runtime that
provides certain tag libraries (JSTL, JSF,...) as part of the runtime would
typically (I believe) contribute these libraries as part of the runtime
specific classpath container (for which WTP has a mechanism for updating
the classpath when the target runtime is switched on a project).  

Let me know if there is a solution for
this that I am unaware of.  If not, I will open a defect.

Thanks,
