Hello,
We need to change the JVM for our IS 6.0.1 but whenever we edit the JAVA HOME variable in the IS server.bat and start it we get the following error. I guess this is something to do with the security policy of JVM. Can anyone help us out…

Current JVM version is JVM 1.6
We want to point to JVM 1.4.2

check to see if the file jce.jar is present in the \jre\lib folder. I have had that problem once and removing this file from the folder seemed to resolve this problem. The file jce.jar is what causes this problem.

just rename the file to jce.jar.bak in 1.4.2 JVM home\jre\lib, edit server.bat to point to JVM home and restart your IS. It should resolve your problem.

HTH,
Z
