Issue in identifying java object

Hello,

I installed java add in in UFT 12.0. Since it identified java objects as web objects,i mad changes to the environment variables  as per the installation guide.But even then its still identifying as web objects.

"

This happens when the JVM does not use the Java Add-in’s settings from the
environment variables. In this case, you need to set -agentlib:jvmhook
-Xbootclasspath/ a:"<UFT installation folder>\bin\java_shared\classes";"<UFT
installation folder>\bin\java_shared\classes\jasmine.jar" in the JVM Runtime
Parameter"

"The tool is available from: Start > All 

Programs > HP Software > HP Unified Functional Testing > Tools > Java
Add-in JRE Support Tool"

But im not able to open JRE Support tool.it gets struck.

Thanks In Advance
