Class LegstarTcpProtocol

java.lang.Object
  org.mule.transport.tcp.protocols.AbstractByteProtocol
      org.mule.transport.tcp.protocols.DirectProtocol
          org.mule.transport.legstar.tcp.LegstarTcpProtocol

All Implemented Interfaces:

org.mule.transport.tcp.TcpProtocol

public class LegstarTcpProtocol
extends org.mule.transport.tcp.protocols.DirectProtocol

This application level protocol is compatible with the LegStar z/OS LSOKBIN module. After the initial connection dialog, the client is expected to send data formatted like so: Data item Length Offset Purpose -------------- ------ ------ ----------------- Message type 8 0 Type of service String delimiter 1 8 Binary zero Message x 9 Variable size Acceptable values for message types are: LSOKEXEC :A request to execute a program. LSOKDATA :Input data for a request. LSOKUOWC :A unit of work command. LSOKPROB :A probe used to check if server is alive.
