Why is itshowing your JDK 'C:\Program Files\Java\jre7' is not a valid JDK while installing WebLogic server?

Question

It\'s showing -

This installer must be executed using a Java Development Kit (JDK)
         


        

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:\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

Answer 2

It worked for me after I used this line:

Downloaded fmw_12.2.1.1.0_wls_quick_Disk1_1of1 and extracted to C:\Softwares\OracleFustionMiddleware and then from command prompt

C:\softwares\OracleFusionMiddleware>"C:\Program Files\Java\jdk1.8.0_91\bin\java. exe" -jar fmw_12.2.1.1.0_wls_quick.jar

Answer 3

• Go to JDK folder
• Run like this:

E:\wlinstallnfile\fmw_12.2.1.3.0_wls_Disk1_1of1>"E:\ATG\software\Java\jdk1.8.0_201\bin\javaw.exe" -jar fmw_12.2.1.3.0_wls.jar**

Answer 4

The issue is due to the java is pointing to JRE instead of JDK

Execute the java from the JDK folder like below:

c:\Program Files\Java\jdk1.8.0_60\bin\java.exe” -jar “<FILENAME>.jar”

Answer 5

You can install it by giving the full path:

C:\Program Files\Java\jdk1.8.0_131\bin\java" -jar fmw_12.2.1.2.0_wls.jar

Answer 6

this is the solution. Specify temp directory having more space like the following example.

java -Djava.io.tmpdir=C:\Temp -jar fmw_infra_121200.jar
