So why, when I attempt to debug a servlet ( By (a) setting a breakpoint,
(b) starting Tomcat via Sysdeo Plug-in, and (c) calling a servlet routine
per JSP link ), do I get an error message:
"Attempting to install a breakpoint in the type
org.apache.artimus.FindByArticle that has no line number attributes. The
breakpoint cannot be installed. Class files must be generated with the
line number attributes.
Reason:
Absent Line Number Informaton"
All responses are gratefully appreciated.

Did you actually compile that class? It sounds like it's from a library jar.

It is an application class file, not a library file. I have forced a
complete rebuild several times to get it to recognize that it should write
the line numbers.
Should I just use Ant? Do you have a troubleshooting routine to recommend?
best reagrds,

I'd actually look at the class file (I think javap does that). If your
class file has line number info, the problem is on the debugger side,
otherwise it's on the compile side. Also, delete the class file in
question and check if it's getting rebuilt.
