Tomcat debugging question

[Bernard]

Hi,

I understand that running Tomcat on a development computer with the
built in HTTP server will let me debug servlets in an IDE.

Now I am running Tomcat on my local computer but I cannot see any 404
errors in the Tomcat logfile.

Does the web server support any such logging?

Otherwise, if I use Tomcat with Apache, then is there a way to debug
servlets?

Many thanks.

Hi,

Please note that this question is tomcat-related, not java.

However, in the server.xml (conf dir), you will have to uncomment the
"Valve" with classname
org.apache.catalina.valves.AccessLogValve.

Regards,

Arnaud

What Tomcat version? What JDK?

With Tomcat 5.0.x and JDK 1.4.x you can debug tomcat with the java debugging
interface.

For Eclipse there is the sysdeo plugin, but you can also use your own
debugging.
I've changed the startup.bat of Tomcat 5.0.x and changed the lines between
:doneSetArgs and :end

:doneSetArgs

set JPDA_TRANSPORT=dt_socket
set JPDA_ADDRESS=8000

call "%EXECUTABLE%" jpda start %CMD_LINE_ARGS%

:end

In Eclipse open the debug configuration dialog and create a new debug
configuration for "Remote Java Application". Select your project and look
that the connection properties are correct (Host: localhost, Port: 8000).
Enjoy debugging servlets.

The logging question is answered in the other post (Keyword: Valve).
