[shobha2k8]

When I typed the command as 'java -version' in commandprompt its showing "java version 1.3.1_01"

but I want to set it to latest version of java which is in the path C:\Program Files\Java\jdk1.5.0_06

I have added the environment variables user variables JAVA_HOME value as C:\j2sdk1.4.2_12.

Could you please help me out soon.

Do you have two versions of Java installed?

You probably have a few versions of java installed, if you are on windows look in your java folder.

If you look in C:\WINDOWS\system32 you will see a version of java there, if you look at your path variable I expect that system32 is at the beginning of it.

Move your jdk value to the start of your path variable and this is the one that will be picked up from now on, you will be able to confirm this by typing java -version again and you will see the version you want.

Cheers.

Ps hope this makes sense!

Yes, that's what I want to pointed. There is few versions of installations are found. Why don't you use the latest version of Java?

hi,

In order to set the new version, do the following :

1. Create a System variable by name "JAVA_HOME".
2. Give the value for that variable as C:\Program Files\Java\jdk1.5.0_06.
3. Create another System variable by name "CLASSPATH" and give the value as C:\Program Files\Java\jdk1.5.0_06. if already you have CLASSPATH variable, than just include (append to previous) the value C:\Program Files\Java\jdk1.5.0_06.
4. Close all the files and open again.
5. Now you type the command as 'java -version' in commandprompt.
6. if than also it wont work means , you do the same procedure for System variable "PATH" and value is C:\Program Files\Java\jdk1.5.0_06\bin.

I hope it will work.

I could be wrong, but I think the value PATH is the one you should change as I explained in my post above. If you put your jdk entry at the start of the PATH variable it will pick it up.

I believe JAVA_HOME is used by applications such as tomcat and ANT, I don't think it is used by windows OSor the JVM (please correct me if I am wrong though).

Whenever I have experienced this problem, changing JAVA_HOME has no effect, changing PATH does.

Uninstall the old jdk,(that installation configures the path, so that should remove what that old jdk installation done when uninstalled) if you done it by yourself, simply remove what you have done in the environment variable....

and intall the new Version of JDK...
