Remote debugging on Tomcat with Eclipse

I'm trying to initiate a remote debugging session on my PC with Eclipse & Tomcat. I managed to run tomcat (not through eclipse) with the following params:

set JPDA_TRANSPORT=dt_socket
set JPDA_ADDRESS=5050
cataline jpda start

The server starts ok, this is the outcome:

Using CATALINA_BASE:   "C:\Java\Tomcat"
Using CATALINA_HOME:   "C:\Java\Tomcat"
Using CATALINA_TMPDIR: "C:\Java\Tomcat\temp"
Using JRE_HOME:        "C:\Java\jdk1.6.0_27"
Using CLASSPATH:       ...
Listening for transport dt_socket at address: 5050
...
...
INFO: Server startup in 12502 ms

Now, I opened eclipse, and loaded the relevant project.

I set a new debugging configuration using Remote Java Application with localhost and the right port. however when I run it, I get this error message:

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

Can't really understand where is the problem. this is all local inside the PC, so there shouldn't be any firewalls involved, can someone think of something ?

You can configure it in remote java application section in debug configuration. For more details you can refer this link

There could be problems when there are code mismatches between eclipse and tomcat. So when it matches the error will disappear

Found the solution. apparently the connection was made, but Eclipse & Tomcat don'tt show any notification or status regarding it. Then, when you initiate the connection again, you get the error because you're already connected.

I think that a small notice, either from Eclipse, or from Tomcat would be nice.

Try adding the following debug options directly to the JVM startup by directly modifying the catalina startup script

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5050
