Passing java Arrays via Session object on ASP

How can I store a java array created in one function for use in other java functions?

I have tried using the session object but am unable to pull the java array back out of the session object.

I did this:

var a = new Array();
a[0] = 1;

Session("MyArray") = a;

then in other function, I do this:

b = Session("MyArray");

Which gives an error about not having an object.
