Hi,
When I try to run eclipse debugger, I am getting the error:
Failed to connect to remote VM. Connection refused

this are Steps for  Debugging from within Eclipse that I made

1)In the eclipse window (Run/Debug configuratio),I selected "Remote Java Application" from the list of configurations and with Right click on the "Remote Java Application" and I created a new configuration as following

On the "Connect" tab I set the connection properties with values host as "localhost" and port as "8000".

2) In the enviornment variables, add an entry jpda_address=8000;

3)In catalina.bat .  I wrote " set JPDA_TRANSPORT = dt_socket ".

4)In startup.bat I wrote comand call "%EXECUTABLE%" jpda start %CMD_LINE_ARGS%


development enviroment:
-Alfresco 3.2 is installed   on the Virtual machine with firewall disabled .The OS is WXP
-Eclipse Java EE IDE for Web Developers.   Build id: 20090621-0832

Thanks a lot in advance

I think you are missing some configuration.

Here's mine.

set DEBUG_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n

I read in developer guide, as to configure Tomcat.See below

——————————————————————————————————————————-
Follow these steps to set this up:
1. Set the JPDA_TRANSPORT environment variable to dt_socket.
2. Set the JPDA_ADDRESS environment variable to 8000.
3. In Tomcat's startup script, change the line that invokes Catalina to include
jpda. On Linux, this looks like:
exec "$PRGDIR"/"$EXECUTABLE" jpda start "$@"
4. Start Tomcat. You should see a message like "Listening for transport
dt_socket at address: 8000".

5. In Eclipse, go to the Debug Configuration dialog and create a new Remote
Java Application. Browse to the project you want to debug. Take the defaults
for everything else:
6. Click Debug.


——————————————————————————————————————————-

Now on the command "JPDA_OPTS=-agentlib:jdwp=transport=%JPDA_TRANSPORT%,address=%JPDA_ADDRESS%,server=y,suspend=%JPDA_SUSPEND%"
for "developer guide" the parameters "set JPDA_ADDRESS=8000",
while on the command on the post
          "set DEBUG_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n" is "JPDA_ADDRESS=4000".
the value is 4000.

which is right one?

thank you kindly

I had this problem on Windows 7 and was able to work around it by changing the JPDA port from 8000 to 1044.
