 What's the best way to debug servlets?  Is there software or scripts that
can
 parse through the log files?  Catalina.out doesn't have timestamps.  And,
 there's all those other log files as well.  Seems a bit cumbersome.
Thanks
 for any tips.

Hi.

I've never done this, so im not 100% sure, but this should work according
to docs.

Modify catalina.sh-script so that CATALINA_OPTS-parameters value is  the
options you use normally (-Xdebug -Xnoagent
-Xrunjdwp:transport=dt_socket,address=,server=y,suspend=y), except add
-Djava.compiler=NONE to it.

Debugging servlets is propably a little different then normal java apps.
Docs say that

   1.  Set one or more breakpoints in your servlet code.
   2.  From the Run menu, select Debug servletname.java.
   3.  Start the servlet running (for example, start your web browser
 and open a connection to the servlet).
   4.  Debug as normal.

If your using Oracle's JDeveloper you should propably use JDevelopers
servler.jar instead of tomcats. Don't know about JBuilder.

Re: Debugging Servlets

2002-07-12 Thread Jacob Kjome 

I use bugseeker 1.0.2 for Java2:
http://www.karmira.com/products/bugseeker2/

I created a new environment variable:

JPDA_FLAGS = -Xdebug -Xnoagent -Djava.compiler=NONE 
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000

Then I created a Tomcat Service which I use exclusively for debugging:

%CATALINA_HOME%\bin\tomcat.exe -install Apache-Catalina-JPDA 
%JAVA_HOME%\jre\bin\server\jvm.dll 
-Djava.class.path=%CATALINA_HOME%\bin\bootstrap.jar;%JAVA_HOME%\lib\tools.jar 
-Dcatalina.home=%CATALINA_HOME% %JPDA_FLAGS% %CATALINA_OPTS% -Xrs -start 
org.apache.catalina.startup.BootstrapService -params start -stop 
org.apache.catalina.startup.BootstrapService -params stop -out 
%CATALINA_HOME%\logs\stdout.log -err %CATALINA_HOME%\logs\stderr.log

I am able to attach to the socket using bugseeker's remote debugging.  You 
should be able to do the same in JSwat.

If you want to use bugseeker and want a project that is set up to work 
properly to debug Tomcat servlets, send me a personal email and I'll send 
you the project file.

CATALINA_OPTS set (-Xdebug -Xnoagent -Djava.compiler=NONE

I must be doing something fundamentally wrong as

easy... :-)))

Help appreciated!
