It's showing -

but C:\Program Files\Java\jre7 is not a valid JDK.

</>- while installing the WebLogic server.

I have installed the 64-bit JDK version 1.7. Where am I making a mistake?

i faced the same problem even when JAVA_HOME points to JDK this is how i resolved it ,

  1. run command prompt as administrator

  2. go to the directory which contains your jar file

    C:\Windows\system32>cd/
    
    C:\>cd oracleweblogic
    
  3. Set JAVA_HOME and path again on the command prompt

    //put path in double quotes otherwise it won't recognize variable

    C:\oracleweblogic>set JAVA_HOME="C:\Program Files\Java\jdk1.8.0_45"
    
    C:\oracleweblogic>set path=C:\Program Files\Java\jdk1.8.0_45\bin;%path%
    

    If you have already set the JAVA_HOME then in the second step you can also type as: C:\oracleweblogic>set path=%JAVA_HOME%\bin;%path%

  4. run the jar file

    C:\oracleweblogic>java -jar fmw_12.2.1.1.0_wls_quick.jar
    

you should see something like this if your setup is correct

C:\oracleweblogic>java -jar fmw_12.2.1.1.0_wls_quick.jar
