That problem was discussed in the nbuser group a couple of weeks ago, in conjunction with code completion. Try to put jstl.jar struts-el.jar struts.jar servlet.jar into NetBeanXX/lib/ext and standard.jar into NetBeansXX/lib Maybe you can put everything under ..../lib or .../lib/ext.

Hi,
I searched the mailing list archives and the bugzilla database, but couldn't find an answer, so please excuse me if this is a FAQ.
I am unable to compile any JSP that uses any of the html-el tags under the embedded Tomcat in Netbeans 3.5.1. The stacktrace follows:

What could be wrong? I get this with my own application, as well as the strutsel-exercise-taglib webapp where this example is from. We're also having the same problem deploying the application under WLS 7.0 and 8.1. ###########################################
