XMS primitive types

XMS provides equivalents of the eight Java primitive types (byte, short, int, long, float, double, char, and boolean). This allows the interchange of messages between XMS and JMS without data becoming lost or corrupted.

Table 1 lists the Java equivalent data type, size, and minimum and maximum value of each XMS primitive type.
