remote debug
Hi:
I have a project and want to use the remote debug manner,my web
container is tomcat of version of 5.5,I have seen the faq in wiki of
tomcat.
I follow the instruction:
----------
%CATALINA_HOME%\bin\tomcat6w.exe //ES//tomcat6
Select the Java tab in the properties dialog box,
Add the following two lines to the Java Options text box:
-Xdebug
-Xrunjdwp:transport=dt_socket,address=192.168.2.10:1044,server=y,suspend=n
--------------------------------
after the configuration I restart the tomcat.
then in my eclipse EE I open the debug configuration dialog,create a
new "remote java application",in the connection properties I set :
host:192.168.2.10
port:1044
Then I click applay--debug.However a error dialog comes out which tell me:
Failed to connect to remote VM. Connection refused.
Connection refused: connect
I wonder why?
I have tried to Set environment variables JPDA_ADDRESS=1044 and
JPDA_TRANSPORT=dt_socket,but it does not work also.
Anyone can give me some advise?

Hi:
I have changed to tomcat 6.0.20(zip),.
And I follow the running.txt under its install directory,use the startup.bat
to start the tomcat,it works.
Then I shutdown the tomcat and want to config the remote debug in the
eclipse EE.
1> I set the environment variable
JPDA_ADDRESS=1044
JPDA_TRANSPORT=dt_socket
2> I start the tomcat with debug "catalina.bat jpda start", and a new
command window startup and it shows
"Listening for transport dt_socket at address:1044"
...................................
"Server startup in 448 ms",
I think it start successfully.
3> In my eclipse EE,I create a new debug configuration and try to connect
the tomcat,however it show the same error:
"Failed to connect to remote VM. Connection refused."
Is there something wrong in my configuration ?
BTW, does the remote debug means I can debug my web app in computer A with
tomcat installed at computer B?

Wherever you heard that is wrong. There were significant config differences between 4.1, 5.0 (no longer supported), and 5.5, but very few config changes between 5.5 and 6.0 (other than clustering). What changes there were is documented here:

Thanks for your reply.
I used 5.5 rather than 6.0 because I heard that 6.0 is much different with
5.5 in configuration(such as the port and ect..),I will have a try with the
6.0.zip.Thank you again :).

The version of Tomcat doesn't matter, although unless you have a compelling reason to use an older level, I would go with the current 6.0.20 zip file.
Generally, things are easier to debug when starting Tomcat via the .bat scripts rather than as a service, partly since you get to see in a command window if there are any startup errors. Create a setenv.bat script in Tomcat's bin directory to hold any command-line parameters you want to set.
Once you're ready to try Tomcat as a service, install it with the service.bat script, and use the tomcat6w.exe program to set additional options and start/stop the service. No point in trying to use the tomcat6.exe program directly - it's too hard.

In a word,I have two choice:
1 use the tomcat.zip of version 5.5 or 6.x.
2 use the tomcat.exe of version 6.x?
isn't it?

Then how it is possible you're fiddling with tomcat6w.exe, which is part of Tomcat 6.0, not 5.5?

I would uninstall the .exe version. You can create the service with the service.bat script from the .zip download.

That's to say if I want to use the remote debug ,I should use the
tomcat.zip? Should I uninstall the tomcat I am using?

One of the above two statements is wrong. Which version of Tomcat are you really using?
> Failed to connect to remote VM. Connection refused.
> Connection refused: connect
What version of Windows are you using? I can get JMX/JPDA working with a Tomcat service on XP, but not on Vista (haven't tried it on Win7 yet). JMX/JPDA works with Tomcat started from a command prompt on both XP and Vista. (The .bat scripts are only in the Tomcat .zip download, not the .exe, for some inexplicable reason.)
