Question

It's showing -

This installer must be executed using a Java Development Kit (JDK)
but C:Program FilesJavajre7 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?

Answer 1

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:Windowssystem32>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 FilesJavajdk1.8.0_45"
   
   C:oracleweblogic>set path=C:Program FilesJavajdk1.8.0_45in;%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%in;%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
