Workshop cannot start "localhost" server

Question

Hi,
I'm using Workshop 10.3 (from Oracle Service Bus 10gR3) on a Windows XP machine.
I have to run my domains strictly on "localhost". I've edited the default OSB and Workshop domains (i.e. ${OSB_HOME}/osb_10.3/samples/domains/servicebus and ${OSB_HOME}/workshop_10.3/samples/domains/workshop) and defined a "<listen-address>" of "localhost". For example, the workshop domain's config.xml contains:
  <server>
    <name>cgServer</name>
    <ssl>
      <name>cgServer</name>
      <enabled>true</enabled>
       <listen-port>7002</listen-port>
    </ssl>
    <listen-port>7001</listen-port>
    <listen-address>localhost</listen-address>
  </server>
...When I start a server for either of the two domains from within the Workshop IDE, I get an error claiming that the server failed to start because it's occupied. For example, the OSB samples domain give the following error log:
!ENTRY com.bea.workshop.wls.core 1 2000 2010-03-31 14:04:19.114
!MESSAGE Server watcher[Oracle WebLogic Server v10.3 at localhost (OSB samples domain)]:running Weblogic detected, validating...
!ENTRY com.bea.workshop.wls.core 2 2 2010-03-31 14:04:19.192
!MESSAGE Unable to validate WebLogic domain.
Please make sure the running WebLogic instance is an Administration Server
!ENTRY com.bea.workshop.wls.core 4 4000 2010-03-31 14:04:19.630
!MESSAGE Another server (or another process) is running on the same TCP/IP port '7021'.
!ENTRY org.eclipse.wst.server.core 4 0 2010-03-31 14:04:19.661
!MESSAGE Server Oracle WebLogic Server v10.3 at localhost (OSB samples domain) failed to start.I can guarantee that there's nothing already running on port 7021/7022 (or 7001/7002 which is mentioned when I try to start the Workshop domain with the same failing result). If the server is not running I can see with "netstat" that nothing's using those ports and a telnet to either port will simply fail to connect to localhost.
In fact, the Workshop IDE simply thinks that the server process failed to start, when in fact it is running successfully. If I access (e.g. for OSB) http://localhost:7021/examplesWebApp/index.jsp I get the samples screen (in fact the browser is started on this address automatically) and can run the samples. I can also access the console by going to http://localhost:7021/console.
However, Workshop thinks the server is dead and I cannot publish/run projects on the server from within the IDE.
Any ideas why?

Answer 1

The problem is related to the fact that the server does not accept connections using the T3 protocol.
For more details, see Can't connect to administration server using "t3" protocol
It has not been resolved, but I have an SR pending with Oracle support.
