I am running Wildfly as a service on windows. When I need to debug, I am shutting this down and starting Wildfly via standalone.bat -debug. What I want is to have the debug switch on always, when it runs as a service?
Uncomment following JAVA_OPTIONS from $JBOSS_HOME/bin/standalone.conf.bat
rem # Sample JPDA settings for remote socket debugging
set "JAVA_OPTS=%JAVA_OPTS%
-agentlib:jdwp=transport=dt_socket,address=8787,server=y,suspend=n"
start service. Now you can detach a debugger with your favorite IDE. If you are using Eclipse you can switch to "Debug-Configurations" and add a new Remote Java-Application.
I'm using WildFly 11 and uncommenting the following lines in bin\standalone.conf.bat (windows) did the job:
set "DEBUG_MODE=true"
set "DEBUG_PORT=8787"
Open the command line and set java options with the following debug options:
set JAVA_OPTS = -Xdebug -Xrunjdwp:transport=dt_socket,address=8787,suspend=n,server=y
start wildlfy service by running standalone.bat or standalone.sh for windows/linux respectively

I'm using Liferay Developer Studio 3.8 and Liferay Portal Tomcat 7.3.1.
I would like to know how can I debug Liferay code, given that the usual Eclipse option as "Watch" or "Inspect" are disabled even starting the server in "Debug mode"?
Also, I cannot use the "Variables" perspective or the "Debug Shell".
Options disabled
Variables disabled
Does somebody know a dummy manual to debug in Liferay?
Thanks in advance.
Edit: The line suggested by Purvesh is already inserted in setenv file.
Following the steps provided by Andre, I still cannot add variables or insert expressions in debug shell. And also, nothing happens with the breakpoints at lines 68 and 69.
Remote debugging
You can start your server with catalina.sh jpda start (guess this should works with .bat too). In eclipse run „Remote Application“ Debug. Your debug Port should be 8000 (per default).
Add Below line in your setenv.bat/setenv.sh file.
CATALINA_OPTS=%CATALINA_OPTS% -Dfile.encoding=UTF8 -Djava.net.preferIPv4Stack=true
Restart tomcat server.
Set debug configuration and put breakpoints.
Run your application.
I have googled this extensively before posting it here. I've been trying to find out a way to enable JMX Access on a Tomcat instance installed as Windows service. Its quite straightforward when Tomcat is invoked via the startup.bat script, one just needs to set the CATALINA_OPTS environment variable to something like "-Dcom.sun.management.jmxremote.port=1234 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false"
But how do i get the Tomcat Windows service to read these options? I tried this:
C:>tomcat\server\bin> service.bat install #install the Tomcat7 windows service
C:>tomcat\server\bin> tomcat7.exe //US//Tomcat7 ++JvmOptions "-Djava.io.tmpdir=$INSTDIR\server\temp;-XX:MaxPermSize
=256m;-Dcom.sun.management.jmxremote.port=8090;-Dcom.sun.management.jmxremote.au
thenticate=false;-Dcom.sun.management.jmxremote.ssl=false" --JvmMs 256 --JvmMx 1
024 #update the installed service using the //US switch; set tmpdir, JMX access and heap size
When i start the service from Services panel, the service fails to start and i get the following error on the logs\tomcat7-stderr-yyyy-mm-dd.log file:
yyyy-mm-dd hh:mm:ss Commons Daemon procrun stderr initialized
Error: Invalid com.sun.management.jmxremote.port number: 8090 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false
I don't have a Java background, am i trying to achieve something outlandish here? Please advise.
Answering my own question; turned out to be easier than i thought.
Following needs to be done, for enabling JMX access for Tomcat installed as a Windows service, that has a name "ApacheTomcatWindowsServer" for example:
Install Tomcat as Windows service, either using the command (first cd into \bin\ )
service.bat install
or your custom scripts.
Enable Apache Service Manager for the installed service using the following command:
tomcat7w.exe //MS//ApacheTomcatWindowsServer
This should start Apache Service Monitor program on your system tray. Click on its icon. select 'Configure', click on the 'Java' tab and append the following on the 'Java Options' text box, one option per line:
-Dcom.sun.management.jmxremote.port=8090
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
Save and exit and restart the service.
To connect to the JMX console, fire jconsole from your JDK installation, click 'New Connection', specify 'Remote Process' and enter hostname:8090.
you can also uninstall the service by
service.bat remove
then edit the service.bat and add the parameters in your StartPath and add the options
-Djavax.management.builder.initial=;-Dcom.sun.management.jmxremote.port=8090;-Dcom.sun.management.jmxremote.authenticate=false;-Dcom.sun.management.jmxremote.ssl=false
here is the sample StartPath in my file
--StartPath "C:\tomcat7\" --Startup auto --JvmOptions "-Dcatalina.home=%CATALINA_HOME%;-Dcatalina.base=%CATALINA_BASE%;-Djava.endorsed.dirs=%CATALINA_HOME%\endorsed;-Djava.io.tmpdir=%CATALINA_BASE%\temp;-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager;-Djava.util.logging.config.file=%CATALINA_BASE%\conf\logging.properties;-Djava.rmi.server.hostname=;-Djavax.management.builder.initial=;-Dcom.sun.management.jmxremote.port=8090;-Dcom.sun.management.jmxremote.authenticate=false;-Dcom.sun.management.jmxremote.ssl=false" %JAVA_OPTS% ^
re-install the service by
service.bat install
then start Tomcat to apply changes
I am trying to run remote jboss in debug mode to debug my application and i have set
set JAVA_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=y %JAVA_OPTS%
in run.bat file, and am trying to start the jboss server using ant jboss.start but it is taking some time and then timing out, am not sure why this is happening, is there a way out?
Also as jboss is timing out, I would like to increase bootup time for the server, how can i do it from the command line?
Side note, server.log file does not show any messages which jboss is trying to bootup in debug mode (not sure if this would help but thought so sharing this info.)
Any clue or suggestions?
You should set:
suspend=n
in debugger startup settings.
suspend - True if the target VM is to be suspended immediately before the main class is loaded; false otherwise.
Your JBoss waits infinitely for debugger connection, this is useful when you want to troubleshoot startup issues, otherwise do not suspend your VM and let the debugger be connected any time you want.
I was frustated to get jboss started in debug mode through command line
Finally following seemed to work
1.Below should be the last line in /bin/run.conf.bat
rem # Sample JPDA settings for remote socket debugging
set JAVA_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n %JAVA_OPTS%
If there is anything below this, delete it.
2.Also when you are running jboss from command prompt please check whether -Xdebug is at the start of JAVA_OPTS.
Then it should display following message
Listening for transport dt_socket at address: 8787
3.In eclipse use 127.0.0.1 instaed of localhost.
I don't know the reason behind it...but when I changed localhost to 127.0.0.1 it worked
(Make sure you replace localhost with 127.0.0.1 at 2 locations 1.Eclipse remote debug and 2.URL while running your application in browser)
Also check project name.
Sometimes we need to change the port number.
I never had such issues with tomcat.
How do you enable remote debugging in JBoss 5? The usual line from JBoss 4:
set JAVA_OPTS= -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n %JAVA_OPTS%
As can be found in other answers like this do not seem to work. The server never suspends. Googling "jboss 5 remote debug" doesn't bring up anything in the JBoss docs. Did something change from JBoss 4? How can I remotely debug my JBoss 5 server from eclipse?
You have suspend=n in your options. Change this to suspend=y.
Or is the line you posted not the one you're using with JBoss?
We have to do 2 changes to debug remote java application that is running in JBoss
Configure in JBoss
Creating remote debugger in in eclipse
Open run.conf.bat(windows) or run.conf(Linux) file in JBoss bin folder.
go to the below lines
`# Sample JPDA settings for remote socket debugging`
#JAVA_OPTS="$JAVA_OPTS -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n
and remove hash in JAVA_OPTS
# Sample JPDA settings for remote socket debugging
JAVA_OPTS="$JAVA_OPTS -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=y
Restart the server if it is started.
2. In Eclipse, Run -> Debug configuration -> Remote Java Application and create a new.
Note that you have to give port that is mentioned in run.conf.bat file
I'm unable to find an option to setup remote debugging in JBossWeb 2.1.4 on Windows. It is not installed as a service and there are no .bat scripts where I can edit the JAVA_OPTS environment variable to include:
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=4142
The only thing in the jboss web bin directory are jbossweb.exe files.
I've tried editing the run configuration in eclipse to start the container by running jbossweb.exe and setting the environment variable JAVA_OPTS to the above, but it doesn't listen on port 4142 on startup (ie, there seems to be no effect in adding the environment variable to the run configuration).
Any ideas here?
If you control the server from eclipse with for instance JBoss Tools, you can just click "debug" instead of "start" in the Server pane in order to start up in debug mode.
You can create such bat script by yourself. Just add jboss.bat file to bin subdirectory of JBoss install directory and put there:
java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=4142 -jar "D:\JBoss.org\JBoss Web 2.1\bin\bootstrap.jar" start
When you run this script, you will get JBoss running in debug mode. Probably, it won't help you in all situations, but it worked for me.
