How to remotely debug the webapplication running on tomcat service?

问题

I have my webapplication on tomcat 6 at serverA. I am running the tomcat as service i.e thru tomcat6w.exe lying under <tomcat_home>/bin folder. To remotely debug the weabbplication i have added below lines as suggested on different blog/sites on web in different line witout space at end. Mentioned the port as 8443 as application is running on same port.

-Xdebug-Xrunjdwp:transport=dt_socket,address=8443,server=y,suspend=n

Now thru eclipse on server B i mentioned host as serverA and port 8443 and click debug. After 2-3 minutes it establishes connection without giving any error.But now when i hit webapplication url in IE it does not show up and says IE can not display the webpage. But as soon as i remove the above mentioned debug parameters and hit the url, application works fine. I am not getting how should i debug the application when tomcat is running as window service?

For Information Below are the parameters when i double click the tomcat service

In the Java Options tab add the below. Remember to put

-Xdebug

and

-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8733

in SEPARATE LINE.

-Xdebug
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8733

you can pass JVM options using JvmOptions parameter:

tomcat.exe //TS// ++JvmOptions -Xdebug;-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044

tomcat.exe //RS// ++JvmOptions -Xdebug;-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044

When I need to remotely debug an application that is deployed on Tomcat, I usually start the server through the Catalina.bat script, not as a Windows service. Actually, to enable remote debugging, you're supposed to provide the JPDA arguments when executing the catalina.bat script :

catalina jpda start

If you really need to start your server as a service, you could try to edit its definition so that you also provide the JPDA argument to it.

Yo could as well stop your Tomcat service and just start the server by executing the catalina.bat script.

Hope that'll help.
