Error on remote debugging WebLogic 10 with Eclipse

[Vivian Josh]

Hi Ranchers,

I am new to remote debug feature and have to make use if it at my new job.

I am trying to remote debug WebLogic10 with Eclipse (J2EE version). I have set debug options in startWebLogic.cmd (as I am using weblogic managed server- wlm.cmd to run my server) but getting error on console.

Error :
JDWP option syntax error:-agentlib:jdwp=transport= ["debugInit.c",L1182]

What is going wrong here ?

I am pasting here changes I amde to my .cmd file.

set DEBUG_OPTIONS= -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=1044,server=y,suspend=n

and my startup server script looks like :

echo starting weblogic with Java version:

"%JAVA_HOME%\bin\java" %DEBUG_OPTIONS% %JAVA_VM% -version

Can someone explain me what is happening here ?

TIA,
Vivian

Hi,

I would start trying to change the $DEBUG_OPTIONS to place it after $JAVA_VERSION

like:

    
 
"%JAVA_HOME%\bin\java" %JAVA_VM% %DEBUG_OPTIONS%

also if you still have the problem, pls post a more complete message from error you get.

Hi Marcos,

I tried changing the position of debug option but still when I run remote debugger it gives me error - "Failed to connect to remote VM. Connection refused.
Connection refused: connect " .

On the console its not showing any error this time.

Here is script running for WLS:

And my startWebLogic.cmd file has following things in it.

set DEBUG_OPTIONS= -Xdebug -Xnoagent -Xrunjdwp:transport= dt_socket,address=1044,server=y,suspend=n

Script :

@REM START WEBLOGIC

echo starting weblogic with Java version:

"%JAVA_HOME%\bin\java" %JAVA_VM% -version %DEBUG_OPTIONS%

Hi,

try declaring your debug parameters using the JAVA_OPTIONS variable,
in startWeblogic.cmd script in line where you have:

    
set JAVA_OPTIONS=%SAVE_JAVA_OPTIONS%

change it to add your debug options(space after suspend=n ok?)

   
set JAVA_OPTIONS=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=1044,server=y,suspend=n %SAVE_JAVA_OPTIONS%
 

then take out your %DEBUG_OPTIONS% from this line

   %JAVA_HOME%\bin\java" %DEBUG_OPTIONS% %JAVA_VM% -version 

this should work. Also make sure you're running weblogic development mode

You should see a line like this on the console where you run startWeblogic script:

Listening for transport dt_socket at address: 1044    

Then you just have to configure a remote Java Application on eclipse and connect to this port.

[Vivian Josh]

Hey Marcos,

Thanks !! My webserver started listening to that port !

I have a message on console saying "Listening to 1044...." and aslo with netstat -a I can see that.

I also created remote debug configuratioon with following details

Project name : javasource
Connection Tyoe : Standard (Socket Attach)
Host : localhost
Port :1044

Still its giving me same error when clicking debug button on this configuration window.

Error : Failed to connect to remote VM. Connection refused.
Connection refused: connect

Hi Marcos,

I solved that issue.

I was making mistake of giving space before and after '=' sign. After removing that it started working smoothly !

Thanks for all your help. I really appreciate that.

Hi,

I am getting the same error and I am not able to debug.

I gave the debug parameters as optional VM arguments

-Xms256m -Xmx512m -XX:CompileThreshold=8000 -XX ermSize=48m -XX:MaxPermSize=128m -Xverify:none -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n -Ddsco.datasource=exodys_oracle -Dweblogic.log.Log4jLoggingEnabled=true -da

Need some help here.

Thanks

Marcos I followed the steps you specified and I was debugging on weblogic through eclipse fine. However when I tried today I am getting the message
Failed to connect to remote VM: Connection refused
Connection refused:connect

Hi,

after try running the server can you see the message on console:
Listening for transport dt_socket at address: 8787

Could you also put some more information on the error you're getting.

regards.

Check if debug port is available. Also try restarting the server. If you still get the error pls post a more complete error message.

regards.

Where are you giving these parameters? In weblogic script or eclipse ? Can you provide some more details?

Also, as Marcos said , try using netstat and see if it listening on specified port address.

[Ashwin Chathuruthy]

I was getting the same till I realised that I did not have the debug mode open and it was connected the first time and all other times it shows as connection refused.

So try opening the debug perspective to check it it has already connected.

Also change the port to some other: Say 7004. (Not really necessary)

I also used netstat -a and one way I could tell the it was connected is that it showed it as ESTABLISHED

Hi Experts,

I am facing the same problem.
I have added the following line in statWeblogic.sh file:

JAVA_OPTIONS="-Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,address=1044,suspend=n -Xdebug -Xnoagent ${JAVA_OPTIONS}"

Also after starting weblogic server in the black window i can see following log message:

Listening for transport dt_socket at address: 1044

After this i tried creating a new Debug Config by using Eclipse. I did following to create Debug Config:
1. Provided ip address of weblogic server under Connection Properties-->Host
2. Provided 1044 under Connection Properties-->Port
3. Click on "Apply" button and "Close"
4. Open Debug perspective and "Debug" the newly created configuration.

I am getting following Error:
"Failed to connect Remote VM. Connection timed out."
I have already taken care of following:
1. Make sure that code in eclipse and jar deployed on weblogic server are in synch.

Following are the details of my environment:
1. Windows 2000 Professional
2. Eclipse Galileo
3. Java 1.6
4. Weblogic 9.3

Please help me, I dont now where actaully the problem is.
Thanks....
