At one point, the remote debug used to work. But for the life of me, I don't seem to be able to figure out what broke it.
I have a flex/Java application. There is a wrapper that starts the tomcat server. I modified the wrapper.conf file to include
-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n
In my flex debug configurations, on the left, I have Remote Java Application. On the right, I have Standard (Socket Attach) as the connection type, 127.0.0.1 (I have tried localhost too) as Host, and 8000 as Port.
The following is the stack trace.
!ENTRY org.eclipse.jdt.launching 4 113 2013-09-03 11:30:49.109
!MESSAGE Failed to connect to remote VM. Connection refused. !STACK 0

Here is a screen shot of the debug configurations.

After much struggles, I finally got it figured out. I had to make two changes.
In my wrapper.conf, I had the following lines.
wrapper.java.additional.9="-Xmx2048m" wrapper.java.additional.10="-XX:MaxPermSize=1024m"
My MaxPermSize was set to a smaller size than Xmx. I had to change that 1024 to 2048.
I then restarted my tomcat and it worked, finally!
