No it is a normal java application (The GWT debugger).

The GWT debugger is completely agnostic with regards to what serves the host page. The GWT debugger is connected to the browser, not the server. The host page can be served from a local JBOSS, a remote Apache, a file, whatever. The GWT debugger doesn't care as it is talking to the browser.
Can you please explain this text from the wiki:
gwt.noserver tells Development Mode that the application is already deployed on JBoss AS (don't use embedded Jetty instance to serve application content)
There are different ways of using the GWT debug mode. One of the ways is to have the GWT debugger spin up an instance of jetty and have your web application deployed in it. Then have it launch a browser with the appropriate url in it. Adding the --gwt.noserver on the command line tells GWT you don't want to spin up the jetty server, that the application you are working with is somewhere else and you will manually go to it.
Or this:
Q: Client-side logs are not persisted on Engine, e.g. $JBOSS_HOME/standalone/log/engine/engine-ui.log. A: Currently, client-side logs are enabled only when debugging the application via Development Mode.
When the application is running normally it is all just javascript running in the browser. There are 'log' statements in the code but no loggers to write the data to. When you are connected to the browser with the GWT debugger the GWT debugger provides a logger to write to.
So how did it reached to the jboss-as log? Should I add configuration to jboss logging to have this?
What listens on port 8700?
In the old environment JBOSS. in the new environment nothing as JBOSS is listening on 8080 and 8443
OK, thanks.
So if I understand correctly, the following is sequence is required:
Build and deploy code: $ make install-dev PREFIX="${HOME}/ovirt-engine" $ "${HOME}/ovirt-engine/share/ovirt-engine/services/ovirt-engine.py" start
You missed this part: 1. cd into the source code directory of either webadmin or user portal. you have to change directory to either frontend/webadmin/modules/webadmin or frontend/webadmin/modules/userportal-gwtp
As the maven gwt plugin is only defined in the webadmin and userportal poms and not in the root pom.
It doesn't make much sense to put the gwt plugin in the root pom, as the root pom has nothing to do with GWT. The plugin exists in userportal and webadmin as those are GWT modules. The debugger is specifically a GWT debugger, you can't debug anything else with it.
Is there any reason why not to add <something> to root pom? Activating the debugger should be generic, right, I mean it should not have any dependency with specific module... the fact that we use maven for that is only as a wrapper, right?
Execute the gwt debugger as standalone $ mvn gwt:debug -Pgwtdev -Dgwt.noserver=true
Connect eclipse gwt debugger to localhost:8000
Navigate to application, add ?gwt.codesvr=127.0.0.1:9997 as suffix, example: WebAdmin: http://127.0.0.1:8080/webadmin/webadmin/WebAdmin.html?gwt.codesvr=127.0. 0.1
:9997 UserPortal: http://127.0.0.1:8080/UserPortal/org.ovirt.engine.ui.userportal.UserPort al/ UserPortal.html?gwt.codesvr=127.0.0.1:9997
In other words, it should not be required to re-compile the code to execute the debugger... as environment is fully deployed.
Well, the above sequence is not working, I wounder what I miss in principal... the mvn gwt:debug complains about: [ERROR] Failed to execute goal org.codehaus.mojo:gwt-maven-plugin:2.3.0:debug (default-cli) on project webadmin: The parameters 'runTarget' for goal org.codehaus.mojo:gwt-maven-plugin:2.3.0:debug are missing or invalid -> [Help 1]
Thanks!
Thanks!
IMO the only thing we could do to improve this is update the make file to provide a target to start the debugger, which basically just calls maven with the appropriate parameters.
