Hi Rochelle,

There's really no right or wrong here since this is almost a usability 
question, but from my experience most users familiar with starting a 
server and seeing console output would expect a similar console view - in 
this case probably one that does a tail on the server log file.

Thanks,

Re: [wtp-dev] how to synchronize start/stop state in server adapter



Hi Tim,

Just getting back to this.  I tried to pull out the initialState=stopped 
and that's a good first step.  As you mentioned, getting the log output 
is one of the next steps I need to handle.  In most cases (barring user 
changes or log rotation), pointing at a file would do what I need.  Is 
the right approach to use a console and an image descriptor to do so?

Thanks,
Rochelle
