Debugging Alfresco Tomcat with Eclipse

[robertmarkbram]

Hi All,

I am trying to debug Alfresco with Eclipse and have tried all of the various solutions I have found on this forum to no avail thus far. I am hoping someone can advise me as to what else to try..

JPDA_TRANSPORT environment variable is set to dt_socket.

JPDA_ADDRESS environment variable is set to 8000.

In Tomcat's startup script (C:\Alfresco\tomcat\bin\startup.bat), changed the line that invokes Catalina to include jpda:

call "%EXECUTABLE%" jpda start %CMD_LINE_ARGS%‍

I start Tomcat and see these messages:

Listening for transport dt_socket at address: 8000
28/05/2010 1:44:42 PM org.apache.coyote.http11.Http11Protocol init
INFO: Initializing Coyote HTTP/1.1 on http-8080‍‍‍

I set up Eclipse debug config as per: [img]http://imagefrog.net/out.php/i88306_alfrescoDebugConfig.JPG[/img]

I get this error from Eclipse: [img]http://imagefrog.net/out.php/i88307_alfrescoDebugFailed.JPG[/img]

I made sure Windows firewall was turned off.

I made sure Eclipse has no proxy information.

I did a "netstat -an | grep -i listen" to confirm port is being listened at. I guess it is:

   TCP    0.0.0.0:8080           0.0.0.0:0              LISTENING‍

Tried advice in this thread: http://forums.alfresco.com/en/viewtopic.php?f=10&t=16023#p53463

1)   Open Catalina.bat [C:\Alfresco\tomcat\bin], find “DEBUG_OPTS=” and add following line..
   set DEBUG_OPTS= -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000

Tried advice in this thread: http://forums.alfresco.com/en/viewtopic.php?f=10&t=1914&p=78489&hilit=debug#p78489

You may also add following line to your alfresco.sh and start the server
   export JAVA_OPTS='-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=y'

How do I prove the server is really listening? Any other ideas would be more than welcome!

Some further information:

When the server has started, I see this on the console (before I even try to connect):

31/05/2010 1:45:41 PM org.apache.coyote.http11.Http11Protocol start
INFO: Starting Coyote HTTP/1.1 on http-8080

Talk about egg on my face! The debugging was working perfectly all along.. each time I tried, Eclipse "did nothing", which I thought was weird - so I tried again and got the error message. What I didn't realise is that Eclipse had started debugging the first time: I just didn't realise it because I am used to Eclipse saying "Shall I enter debug mode?"

What a relief. *whew*
