I had a similar Problem and solved it.
When I installed the Weblogic server, Oracle Forms/Reports 220.127.116.11.0 and the Forms/Reports 18.104.22.168.0 Patch, everytime i made a restart. And for last I started the configuration (C:\...\Oracle\Middleware\%homedir%\bin\config.bat). So when the Domain should be created, I got the Error
at oracle.as.provisioning.weblogic.ASDomain._createDomain(ASDomain.java:2633) ...."
The Problem was, when I made a Restart, the Service "Oracle WebLogic NodeManager (C_Oracle_MW_wlserver_10.3)" was in Running mode and blocked the Port 5556.
So I stopped the Service during the configuration and it worked.
