Failed to connect to remote VM. Connection refused. on glassfish for remote debugging

Question

I checked the solution for this problem in stackoverflow and in other sites but I couldn't find any solution. My problem is when I try to debug by placing breakpoints I am getting the below error saying.

Message: “Failed to connect to remote VM. Connection Refused”

In GlassFish

jvm settings

Debug: enabled (I enabled this option)

Debug Options: -Xdebug -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=9001

in

domain.xml

-Xdebug -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=9001

I changed the default address 9009 to 9001 because 9009 is not working, and we have one glassfish have multiple domains to overcome conflicts for debug default address I changed the address for debug

Eclipse IDE in debug configuration

in Connect

Host: localhost

port: 9001

Allow termination of remote VM (I enabled this options)

in Source

I added all my project files

in common

I enabled debug

as of now for me everything is looking fine but still I am unable to debug the code, can anyone help me how to solve this problem?

Answer 1

When I've seen this problem it's always been a blocked port. Either the server's firewall or some other firewall between you and that server. Make sure the debug port, 9001 or whatever you're configured for, is open.
