I am using NetBeans 4.2 (8/10) build, and Appserver 8.1 EE UR2 build 10 for testing.

Currently after adding a 8.1 EE DAS, the DAS can't be started because the
plugin code does not provide --user option when asking the Admin to start
the domain, which cause the DAS can't be started since --user is a required
option in 8.1 EE.  There was an issue 62184 opened for this.

I am opening a new issue to suggest routing the following error message
from Admin to plugin pop up window, or IDE log messages.log, this is to
help diagnosing the problem.  Currently, both pop up window error message
and messages.log fail to pin point the exact where is the problem.

If there is a way to rout the Admin error message, then it can help not
just this case, it can help all other error condition.  Do you agree ? :-)

Following is the CLI error out when the --user option is not given in
start-domain command.

d:\AppServer Install\8.1 UR2\Sun\AppServer\bin>asadmin start-domain
CLI152 user is a required option.
CLI156 Could not start the domain domain1.
