Java Programming

Hi everyone,

I would like to launch webstart with JRE autoinstall in x64 machine and got into some issues.

I have 32-bit JRE installed in the machine. Sun documented to use 32-bit JRE to run webstart in x64. However, when I run the default html, it keeps redirecting to autoinstall the JRE. It seems that it could not detect that webstart is already installed. The script is as follows.

Does anybody know how to verify webstart is installed in x64 (if different from 32-bit?

I really appreciate any help.

Thank you.
