           2.1 Changes in Hotfix #4 - Java Fixes
-----------------------------------


1. Installation of Hotfix #4 - Java Fixes
=========================================

1.1 Installation on IBM OS/2, Windows NT, Windows 95 and Windows 98,
    IBM AIX, SUN Solaris, HP Unix
-------------------------------------------------------------------

1.1.1 Which files must be downloaded?

         The Hotfix #4 Java package consists of the following .zip archive:

         WF321XJU.ZIP   -  International language version including the
                           files of the MQSeries Workflow Java component for
                           all supported platforms.

1.1.2 Unpack the files

        Copy the file WF321XJU.ZIP to a temporary directory and unpack it
        with your favourite ZIP tool, e.g:

        jar xvf WF321XJU.ZIP

        This command unpacks the following files
         - fmcojagt.jar
         - fmcojapi.jar

1.1.3 Update your existing MQSeries Workflow installation

        Note: First stop any running MQSeries Workflow Java CORBA Agent and
        Java applications which uses the JAVA API Beans programs before
        installing this Hotfix (e.g. Web Application Servers like WebSphere).

        Depending on your usage of the JAVA CORBA Agent and the JAVA API Beans
        the following dependencies apply:

        - If you are using the JAVA API Beans in conjunction with a JAVA CORBA
          Agent:

          All clients have to be serviced at the same time as the JAVA CORBA
          Agent, otherwise the clients may no longer be able to connect to the
          JAVA CORBA Agent.

          fmcojagt.jar has to be copied to the machine where the JAVA CORBA
          Agent is supposed to run to the directory:

                <MQWF Installation directory>\bin\java3212 - OS/2, Windows NT

                <MQWF Installation directory>/bin/java3212 - AIX, SUN Solaris

          fmcojapi.jar has to be copied to the machines where the Java API
          Beans are being used to the directory:

                <MQWF Installation directory>\bin\java3212 - OS/2, Windows 98,
                                                             Windows 95,
                                                             Windows NT

                <MQWF Installation directory>/bin/java3212 - AIX, SUN Solaris,
                                                             HP-UX

        - If you are using the JAVA API Beans in LOCAL Bindings mode:
          copy fmcojagt.jar to the machine where your Java Application is
          supposed to run to the directory:

                <MQWF Installation directory>\bin\java3212 - OS/2, Windows NT

                <MQWF Installation directory>/bin/java3212 - AIX, SUN Solaris
