JRE 6 Runtime Parameters

I am running java 6 beta 2 because I am on Intels 64-Bit chipset and must run the java program from a browser. If I type in a Xmx setting into the runtime parameters (such as -Xmx768m)the jre will not load. On a 32-bit machine I am able to type in these parameters running JRE 6 and everything works fine. Unfortunately for the program to work I must have a runtime parameter to allocate the memory. Any suggestions?

"I am running java 6 beta 2 because I am on Intels 64-Bit chipset and must run the java program from a browser."

You do not need Java 6 beta 2 because you're on Intels 64-Bit chipset. It sounds like you have confused a few things. There is a special version of the JDK and JRE for 64-bit AMD processors, but you say you have an Intel processor.

What operating system are you using? According to the Microsoft Windows Installation (64-bit) page there is no plug-in version for the 64-bit AMD JRE.

I am running windows xp. I realize I wouldn't have to run JRE 6 normally but since SE 1.5.0 doesn't support any browsers on the intel 64-bit, I was forced to go with 6 beta 2. http://java.sun.com/javase/6/webnotes/install/system-configurations.html

And you need this browser support because... the only possible reason is because you are writing an applet. But you don't run applets from the command line, and you can't specify those options for an applet you are running in a browser anyway. I guess I don't understand your reasoning either.

We are running in an applet for various reasons and look to convert to java webstart in the near future. But for the meantime we are able to set the Xmx settings using some hooks into the java plug-in. But when we add these settings manually in JRE 6 the message "java cannot be loaded" appears. (This occurs with any Xmx setting we add)
 
It is sorta covered in the JavaRanch Style Guide.
