How to move back to earlier version of JDK.

[senthil_kumar29]

Hi,

Currently I am using JDK 1.4.2_08.

I want to move to JDK 1.4.2_05 or 06, Since I experience some problems deploying DCs and Context binding in Developer Studio.

Shall I just uninstall JDK n reinstall the other version.

Cheers.. Sam

Hi,

You can follow the way you have said.

But are u sure abt the root cause of problems deploying DCs and Context binding in Developer Studio is JDK version?

Yeah. Here is the Error while deploying Local DCs.

Ant build finished with ERRORS

Unable to find a javac compiler;

com.sun.tools.javac.Main is not on the classpath.

Perhaps JAVA_HOME does not point to the JDK

I search for post for this error, They have suggested to use JDK 1.4.2.05/06 instead of 08.

Hi,

It seems that you have not set JAVA_HOME system variable?

Check if this variable is set.

JAVA_HOME variable is set.

I checked that in the file C:\usr\sap\J2E\JC00\work\dev_server0
