在 JDK 中找不到 JRE

Question

i install JDK in

C:\Program Files\Java\jdk1.6.0_24

and set the variables as follow:

JAVA_HOME : C:\Program Files\Java\jdk1.6.0_24

CLASSPATH : .;C:\Program Files\Java\jdk1.6.0_24\lib;C:\Program Files\Java\jdk1.6.0_24\lib\tools.jar;

PATH : C:\Program Files\Java\jdk1.6.0_24\bin

but when i run the java -version command, the error

could not open `C:\Program Files\Java\jre6\lib\i386\jvm.cfg'

comes up. then i move the jre folder out the jdk folder to

C:\Program Files\Java\

and change the folder name to jre6 (then it has the C:\Program Files\Java\jre6 folder), everything becomes good then.

why this is happening? it seems to me that it is not the environment variables that are controlling the JVM's location.

Answer 1

If it is not the path that is controlling the location of the JRE it must be the registry:

http://java.sun.com/j2se/1.3/runtime_win32.html .

Answer 2

On Windows 64 bit OS check also: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime Environment

Answer 3

I set my

JAVA_HOME : C:\Program Files\Java\jdk-14.0.2

worked fine for me.
