                         java.lang.String itemPath,
                         java.lang.Object value)

Convenience constructor to build a write request out of basic values. Creates a server node id automatically, with a string based identifier in namespace 0. If a different namespace is required, the ServerNodeId should be constructed manually and passed to the other constructor.
