Click on JSP error to view source [message #512661]

If I do something stupid in a JSP code snippet, the console shows what the error was, and where the error occurred in the JSP file.

However the location given is actually in the application's work directory and not within the project:

Feb 5, 2010 1:21:25 PM org.apache.catalina.core.ApplicationDispatcher invoke
SEVERE: Servlet.service() for servlet jsp threw exception
java.lang.NullPointerException
at org.apache.jsp.pages.location.edit_jsp._jspService(edit_jsp. java:78)

I can go manually to the location (in this case Tomcat, the root directory would be C:\Tomcat\work\Catalina\localhost\app, so the full path to the error would be:

C:\Tomcat\work\Catalina\localhost\app\org\apache\jsp\pages\l ocation\edit_jsp.java at line 78

So a plain text editor could be opened (with line numbers). If I see the code I can then refer back to the JSP within Eclipse.

Does Eclipse provide this, or would it be an enhancement request?

Enhancement request, although one I'm not sure we can address due to
differences between the various servers and the limitations of JSR-45.

Dumb question: couldn't this task be delegated to the server provider? I
mean: in the case of Tomcat, its integration for WTP could provide a way
to open the associated JSP generated source code by opening it from the
work directory. Another server provider would provide another
appropriate mechanism for the same task, if such a mechanism exist.

Interesting idea, you'll have to file a RFE on the Server Tools for that
one.
