Problem

My eclipse Remote Java Application has following connection properties:

Host: 192.168.94.133
Port: 8000

When I run the above configuration, I get:

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

Nothing new comes out of tomcat's log.

But when I telnet from the windows box:

bash-3.2$ telnet 192.168.94.133 8000
Trying 192.168.94.133...
Connected to 192.168.94.133.
Escape character is '^]'.
Connection closed by foreign host.

Every time I try the above telnet, tomcat spits this out in the log:

Debugger failed to attach: timeout during handshake

Because of the telnet behavior, I think the issue is in Eclipse... I'd appreciate any help.

Thanks,

You are probably trying to connect twice to port 8000 from Eclipse (without noticing).

Switch to the Debug Perspective explicitly ("Window - Open Perspective - Debug") and see if you are connected.

Settings required in Tomcat 1)Create setenv.sh file under */tomcat/bin/. The location will be same as the catalina.sh file

2)Place the below content inside it. export CATALINA_OPTS="-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n"

Now start the Tomcat server. Once it is started please proceed with the below steps.

Settings required in Eclipse

3)In Eclipse go to Windows-->Preference--> General-->Network Connection --> Active Provider should be Direct. After changing to direct restart the eclipse.

4)In eclipse right click on project and debug as ->debug configuration ->Remote java application ->Create new configuration. Fill the below fields Name: as your wish Project:Select the project which you need to debug. ConnectionType: Standard socket attach Host: Localhost Port: 8000(It should be same as mentioned in point 2) Then click debug.

The debug will start at port 8000. Now you can verify by keeping breakpoints.
