Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects all users of WebSphere MQ v7.5.0.5 Managed
    File Transfer (MFT) who use a protocol bridge agent to transfer
    files to or from file servers using the FTP or FTPS protocols.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    APAR IT00286:
    
    http://www-01.ibm.com/support/docview.wss?uid=swg1IT00286
    
    should have updated the level of the Apache Commons Net library,
    used by a WebSphere MQ Managed File Transfer protocol bridge
    agent, to v2.2 (filename: commons-net-2.2.jar). The changes made
    under this APAR therefore excluded the older version of this
    library, v2.0 (filename: commons-net-2.0.jar), from the agent's
    Java class path. However the installer for the WebSphere MQ
    v7.5.0.5 Managed File Transfer component did not install the
    newer version of the library.
    
    Therefore, when a protocol bridge agent attempt to perform a
    transfer either to or from an FTP or FTPS file server, the code
    provided by this library was unavailable and
    java.lang.NoClassDefFoundError was thrown.
    

Problem conclusion

  • This APAR corrects the installer for the WebSphere MQ Managed
    File Transfer component such that, for future fix packs, the
    later version of the Apache Commons Net library (v2.2) is
    installed to the "mqft/lib" directory as expected.
