Request Documentation on JNLP/JNI with in 32-bit and 64-bit windows

A DESCRIPTION OF THE PROBLEM :
We programmers need documentation to explain what you are supposed to do when the Windows user has both 64-bit and 32-bit Javas installed. How do you request in JNLP one over the other, or that only one is satisfactory?

Next when you have 32-bit and/or 64/bit JNI DLLs how are you supposed to set up the JNLP to make sure that for example a 64-bit JVM is not loaded when you only have a 32-bit JNI DLL.

Given that Microsoft makes no distiction in extension between 32-bit and 64-bit DLLs, what naming convention are you supposed to use? What do you do with loadLibrary/load.

What values are you supposed to use for "arch".




EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Answers to the questions above. documentation about new features necessary to properly handle a mixture of 32 and 64 bit DLLs and JVMs in JNLP.
ACTUAL -
Nothing. It is silent about anything to do with 32 vs 64 bit Windows.
