How do I tell if I installed 32-bit Java or 64-bit Java?
843829Jun 24 2009 — edited Jun 24 2009I have 64-bit Vista and I just downloaed JDK 1.6u14. I can't figure out how to launch an application from the command line (from the jdk/bin dir) in 64-bit mode. How can I tell if I actually downloaded the 64-bit JDK as opposed to the 32-bit JDK? Is there a special flag to launch applications in 64-bit mode? I tried -d64, but it is not recognized. I noticed that when I launch a Java application, it is reported as "java.exe *32" in the task manager. I never saw that *32 before. Is that an indication that it can be toggled into *64? Thanks for your help. I've been searching through the release notes and other documentation and I can't find this information.
