Installation Error at the time of starting Weblogic Server

Question

Hi All,
I am not a Java guy, so really need help on this problem for Weblogic. I request whosoever trying to explain the resolution to give the details
I have installed Weblogic 9.2 MP3 from edelivery.oracle.com. I have now configured as well one user_domain as well as per the steps mentioned. But when I start the Weblogic Server, I get the following error on command window of Weblogic.
\Java\jre1.5.0_10 was unexpected at this time
I have installed JRE1.5, after I have tried several times the same thing with JRE1.6. Where am I going wroing, I am really not able to figure out. Also, one point, I am not sure how much relevance it makes, when I configured Weblogic user_domain, as I feel, Weblogic should have automatically picked up the Java home, but it did not, and showed Unknown JDK, which I later confirgured with the correct path I had installed JDK/JRE.
Let me know if some log/error files are required.
Any insights on the above problem would be helpful.
Thanks
AJ.

Hi,
You should have JDK installed in your Machine... Not JRE.
Because the JAVA_HOME Variable of WLS Scripts must refer to the Java Standard Development Kit (JDK) not the JRE home.
Example: WebLogic has a Script "config.sh"/"config.bat" to create WebLogic Domains which is placed inside "D:\bea922\weblogic92\common\bin" directory ...There in that file we will find JAVA_HOME variable...which should not point to the JRE Home rather it should point to Something like this:
JAVA_HOME=D:\bea922\jdk150_06
WebLogic will pick up the JAVA_HOME which is defined inside your *"<DOMAIN_HOME>\bin\setDomainEnv.sh"* script Just search for the JAVA_HOME variable in the above script. So it means once the WebLogic Domains are created Different Domains can use Different JDKs...All you need to do is Just set the Correct JAVA_HOME inside your "setDomainEnv.sh" script.
