How to enable Eclipse/Glassfish remote debugging

You would normally enable jdb by adding debug options into your Java start up command by attaching debugging into JVM process, like the following:

DEBUG_OPTS=”-Xdebug -Xrunjdwp:transport= dt_socket,address=1044,server=y,suspend
=n”

You would consider adding this into your Glassfish’s(V2, in my case) start up script asadmin as below:

“$AS_JAVA”/bin/java “$DEBUG_OPTS” -Dcom.sun.aas.instanceName=server -Djava.libra
ry.path=”$AS_NSS”:”$AS_INSTALL/lib”:”$AS_ICU_LIB” -Dcom.sun.aas.configRoot=”$AS_
CONFIG” -Djava.endorsed.dirs=”$AS_INSTALL/lib/endorsed” -Dcom.sun.aas.processLau
ncher=”SE” -cp “$AS_DERBY_INSTALL/lib/derby.jar”:”$AS_INSTALL/jbi/lib/jbi-admin-
cli.jar”:”$AS_INSTALL/jbi/lib/jbi-admin-common.jar”:”$AS_INSTALL/lib”:”$AS_INSTA
LL/lib/appserv-rt.jar”:”$AS_INSTALL/lib/appserv-ext.jar”:”$AS_INSTALL/lib/javaee
.jar”:”$AS_INSTALL/lib/appserv-se.jar”:”$AS_INSTALL/lib/admin-cli.jar”:”$AS_INST
ALL/lib/appserv-admin.jar”:”$AS_INSTALL/lib/commons-launcher.jar”:”$AS_INSTALL/l
ib/install/applications/jmsra/imqjmsra.jar” -Dcom.sun.appserv.admin.pluggable.fe
atures=com.sun.enterprise.ee.admin.pluggable.EEClientPluggableFeatureImpl com.su
n.enterprise.cli.framework.CLIMain “${@}”

Actually this will not work.

You have to log into the Glassfish admin console, under:

Application server

JVM General Settings

Debug
Enabled (check it)

Hit save

Restart Glassfish.

You’ll see Glassfish start up script spits the following message:

Listening for transport dt_socket at address: 9009
Application server is listening at address 9009 for debugger to attach using transport dt_socket

It started to listen at port 9009 by default instead of 1044.

You’ll configure your Eclipse accordingly to do remote debugging. Remember the port number 9009 instead of 1044.

一天的流水帐

本来想去outlet mall的,天公不作美,下起了蒙蒙细雨。后来改作在社区内散步,刚出门,微雨丶大风再加上寒冷的空气,终于让我们彻底打消了出门的念头。

昨天还是阳光灿烂,宛若暑天,今天却如寒冬一般,只能乖乖地缩在家里。只是刚刚洒过除草剂的草地,不知杂草明日会否卷土重来?
