Debug jboss app in Intellij idea - debugging

Question

I am using intellij idea and jboss server.
When I run it it works fine but when I debug it it gives me:
ERROR: transport error 202: connect failed: Connection refused
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [../../../src/share/back/debugInit.c:690]
FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)
Disconnected from server
What is the problem?

Answer 1

Make sure the jboss vm is running with the parameters Idea shows in Debug dialog - specifically the port number seems incorrect to me.

Answer 2

If you're running on OS X Mountain Lion you could try popping -d64 into the VM options, that seemed to work for me. Not passing the variables, I think, will just prevent you from debugging.

Answer 3

Unchecking the pass variables didn't work for me. What I ended up doing running the jBOSS separately and using 'Remote jBOSS' configuration in intelliJ.
To make debugging work I ened up adding the following lines to the "standalone.sh"
DEBUG_JAVA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=localhost:62307,suspend=n,server=y "
JAVA_OPTS="${DEBUG_JAVA_OPTS} $JAVA_OPTS"
The value of DEBUG_JAVA_OPTS has to be copy and pasted from IntelliJ dialog box. These lines have to be inserted into the script right after the place where script sets up "JAVA_OPTS"
Update:
Looks like IDE generates a new port number for each project. So you have to edit the standalone.sh file every time you switch project. Hopefully somebody can suggest a fix for it.

Answer 4

Another option might be to comment out the 'if' statement in standalone.conf as below.
Note the first $JAVA_OPTS is added (it is the one passed in from IntelliJ). This way there is no need to remember to change the port number for every project.
#Specify options to pass to the Java VM.
#
#if [ "x$JAVA_OPTS" = "x" ]; then
JAVA_OPTS="$JAVA_OPTS -Xms64m -Xmx512m -XX:MaxPermSize=256m - Djava.net.preferIPv4Stack=true -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS -Djava.awt.headless=true"
JAVA_OPTS="$JAVA_OPTS -Djboss.server.default.config=standalone.xml"
#else
#echo "JAVA_OPTS already set in environment; overriding default settings with val ues: $JAVA_OPTS"
#fi
