Content assist for taglibs not working in JSP editor [message #827544] Fri, 23 March 2012 09:28 Go to next message
Eclipse UserFriend
The content assist for taglibs in the JSP editor is no longer working. After pressing Ctrl+Space no suggestions are shown. Instead I found an exception in the log files:

From the stack trace, it looks like that Eclipse was unable to update web.xml file. So check your web.xml if there is something wrong there.

The web.xml looks fine, also no problems when running with Tomcat. It is a Maven project and the web.xml is located at "src\main\webapp\WEB-INF". Is it possible that Eclipse can't find it there? However everything worked fine for some time but I can't tell since when it is broken, maybe since the last WTP update.

Does your web.xml refer to a tld file with a path that's only valid when
Maven puts everything together, and are you using WTP without the Maven
support?

Regardless, that exception should not be happening. Please open a bug
report at
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=WTP%20Source%20Editing&component=jst.jsp
and be sure to indicate which WTP version you're using (if in doubt,
check
http://wiki.eclipse.org/WTP_FAQ#What_version_of_Eclipse_does_WTP_work_with.3F).
