Domain instance remote debugging

[aldjinn]

I'm running a JBoss 7 cluster with several instances. Now I want to remote debug a single instance but I don't know how to enable the remote debugging.

There is the default conf "-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n" in the domain.conf file, but this seems to enable remote debugging for the domain controller, not for the running instances.

I've tried to use the <system-properties> settings in the host.xml configuration file of the domain, but this doesn't work also.

<system-properties>

   <property name="runjdwp:transport" value="dt_socket,address=8787,server=y,suspend=n"/>

</system-properties>

Any ideas?

Check the host.xml. It has a commented out example for passing the debug options.

Thanks for the hint, but the usage of

<jvm name="default">

<jvm-options>

  <option value="-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"/>

</jvm-options>

</jvm>

now leads to the following problem:

Exception in thread "Controller Boot Thread" java.lang.IllegalArgumentException: No interface named management exists

This is strange because the management interface is configured:

<interfaces>

<interface name="management">

  <inet-address value="${jboss.bind.address.management:10.18.103.244}"/>

</interface>

<interface name="public">

  <inet-address value="${jboss.bind.address:10.18.103.244}"/>

</interface>

</interfaces>
