Java version for PI 7.0

Hi all,

Our PI 7.0 is running on JVM 1.4.2_21 over Windows Server 2008. For our desktop upgrade from XP to Win7, I had tested on PC to launch Integration Repository (design) and Integration Directory (Config):

Success:

- Win XP with JRE 1.4.2

- Win7 Java 5 with JRE 1.5.0

Fail: Unable to launch the application (Error: Could not verify signing in resource)

- Win7 Java 6 with JRE 1.6.0 and 1.5.0

- Win7 Java 7 with JRE 1.6.0 and 1.7.0

May I know is there any documentation mentioned about Java support on different PI version?

If we upgrade PI to 7.1, is it work fine with Win 7 Java 6 or higher?

Thanks in advance.
