Re: More helpful reporting of exceptions in JSPs

[Tim Fennell]

Hi All,

I've posted my patch for Jasper/Tomcat at the following location:
    http://www.tfenne.com/jasper/

The page has a brief overview, a download link and  "before and  
after" screenshots so you can get an idea for what exactly the patch  
does before you decide to patch your own environment.  If you give it  
a shot and have any problems and/or suggestions for improving it  
please let me know - but please read the readme first ;)

Happy bug hunting.

I certainly don't have a problem with that.  Obviously I'd rather  
have it in the main codebase - while I don't have a problem running  
a patched version of jasper, I'm sure that would freak out a good  
number of PHBs ;)  But since there is interest I'll clean up what I  
have, put it online and post a link here.  That should happen some  
time this evening.

for
distro, with a link to the page sent to tomcat-user  ?

I'd be giving it a try about 10 minutes after you send out your  
email, since
I've often wondered about this feature. Usually right after  
digging through
the work directory for a generated java file.

Apologies in advance for cross-posting this, but I sent this email
out to the tomcat-dev list a couple of days ago and have received no
replies at all...  I think this is quite  a useful feature, and I'm
wondering how best to go about contributing it.
Thanks

At any rate, I have code that will do this now, and I think it'd be
a great productivity boost for anyone else developing JSPs on
Tomcat.  It amounts to small patches to two files.  The first is
org.apache.jasper.compiler.Compiler to make it hang on to


the parse


tree (pageNodes) if in development mode, and a getter to make this
accessible.  The second is to
org.apache.jasper.servlet.JspServletWrapper to do the grunt


work of


mapping a stack frame from the exception back to the line in the
JSP that it came from.
