/*********************************************************

The following parameter types are supported:

1. The following Java primitives and their objectified forms
		boolean, Boolean,
		double, Double,
		float, Float,
		long, Long,
		int, Integer,
		short, Short,
		byte, Byte

   Note: The server side always receives the primitive

2. JavaBeans

   Note:
	a. The JavaBean must not contain other JavaBeans
	b. The JavaBean must not contain vectors or arrays that contain any parameter
	   other than those in 1 and Strings.

3. The following classes:
		String, Vector

   Notes:
	a. A vector may contain all parameters in 1, 2, and Strings. (Exception in 2b)
	b. The server side receives a Vector as an array of Objects

4. Arrays of all parameters in 1, 2, and Strings. (Exception in 2b)
