Error description

  • After upgrading to WebSphere MQ 7.5.0.1, the updated Managed
    File Transfer
    JSch jar file does not get loaded properly due to classpath
    settings.
    
    When the fix pack is installed, the old JSch jar file
    (jsch-0.1.40.jar) is intentionally not deleted. The older JSch
    level is
    intended to remain alongside the new version of the jar
    (jsch-0.1.48.jar).
    

Local fix

  • Rename jsch-0.1.40.jar file to jsch-0.1.40.jar-bak, to prevent
    the file being added to the agent's classpath.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects all users of the WebSphere MQ Managed Filed
    Transfer protocol bridge agent connecting to an SFTP file server
    who have installed WebSphere MQ fix pack 7.5.0.1 over an
    existing WebSphere MQ 7.5.0.0 installation.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM SUMMARY:
    When a WebSphere MQ Managed File Transfer agent is started,
    its classpath is generated based on the .jar and .zip files
    present in the MQ_INSTALLATION_PATH/mqft/lib directory (where
    MQ_INSTALLATION_PATH is the high level directory where WebSphere
    MQ has been installed). As both the older and newer versions
    of the JSch jar file were present, the older version was added
    to the agent's classpath first, followed by the newer version.
    As a result, the older version of the JSch library was used by
    the agent instead of the newer version.
    
    The provision of the updated level of the JSch library is
    documented by APAR IC87351, which is included in WebSphere MQ
    fix pack 7.5.0.1. Accordingly, when applying the WebSphere MQ
    7.5.0.1 fix pack over an existing WebSphere MQ 7.5.0.0
    installation, the issue described by IC87351 will not be
    addressed without performing the local fix instructions for this
    issue.
    

Problem conclusion

  • The WebSphere MQ Managed File Transfer agent code has been
    updated to prevent the older JSch library (filename:
    jsch-0.1.40.jar) from being added to the agent's classpath.
