Implementing Oracle WebLogic AdminServer as Windows Service

Today my fight with the Oracle Internet Directory from yesterday continues (, but this time the problem were related to the Oracle WebLogic Server. I wanted to implement the startup of the underlying Oracle WebLogic AdminServer and ManagedServer of the Oracle Internet Directory installation as a Windows Service.

For this Oracle provides an installation script %WL_HOME%\server\bin\installSvc.cmd which should be called by a wrapper script which we have to create by ourself. (see, but unfortunally if you follow this instruction, you will not be able to startup your AdminServer with a Windows Service. In the corresponding logfiles of the AdminServer you will find entries like:

<BEA-000286> <Failed to invoke startup class "JRF Startup Class" ...

After a little bit of Google Search, I found some articles, which point to the fact that a Java Class (ORACLE_COMMON\modules\oracle.jrf_11.1.1\jrf.jar) is missing in the CLASSPATH variable. So I try this, therefore I modified the %WL_HOME%\common\bin\commEnv.cmd which will be called in the installSvc.cmd and added the fullpath including the jar-file name to the variable WEBLOGIC_CLASSPATH. BIG MISTAKE :-) I did this, and re-created the Windows Service for the WebLogic AdminServer newly and try to startup the new Windows Service. This time I got new and strange exceptions . . .

After some investigations and testings I found a valid and working way, which is really simple :-)
At first in the %WL_HOME%\common\bin\commEnv.cmd I modify the line:

# Original:
@rem PRODUCTION_MODE, default to the development mode
# To:
@rem PRODUCTION_MODE, default to the development mode

As in my case I am running in Production Mode and the declared variable in my wrapper script which calls the %WL_HOME%\server\bin\installSvc.cmd was not taken correctly and secondly I added one line in the %WL_HOME%\server\bin\installSvc.cmd script in order to call the %MW_HOME%\user_projects\domains\<YourDomain>\bin\setDomainEnv.cmd in which all necessary CLASSPATH declarations are included:

# Just add after the first call of the commEnv.cmd
# the call of your setDomainEnv.cmd
. . .
call "%WL_HOME%\common\bin\commEnv.cmd"
call "<YourMW_HOME>\user_projects\domains\<YourDomain>\bin\setDomainEnv.cmd"

After this changes just re-create your Windows Services for the WebLogic AdminServer newly, start the service up and be happy :-)
