How to ensure that a jnlp is run on a 64bits jvm

Question

I have a JNLP applet that is run on a 64bit computer with both 32 and 64 bits JVM installed. The JNLP must run on the 64bit JVM in order to execute correctly. Is there a way to force the use of a 64bit JVM?

Answer 1

Use -d64 the VM option to only allow the virtual machine to start at 64bits. Other way it's simple not start. Not to friendly but make the job. In console mode print:

Error: This Java instance does not support a 32-bit JVM.
Please install the desired version.

-d64 is supported since 1.5.0
