So how did it reached to the jboss-as log?
Should I add configuration to jboss logging to have this?

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
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.UserPortal/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]
