public class WTObjectOutputStream

extends ObjectOutputStream

An object output stream extension that allows runtime configuration of the default protocol version. The JDK 1.2 introduced a new stream protocol version which will cause compatibility problems when read by pre-JDK1.1.7 object stream implementations. This class defaults the stream protocol to it's JDK 1.1 version even when run under JDK 1.2. It allows runtime configuration through Windchill property called wt.objectStreamProtocolVersion.
