    Problem:

    Often when trying to run xwindows applications in your ssh session you may get an error similar to the following:

    > xclock

    Warning: Cannot convert string "-monotype-arial-regular-r-normal--*-140-*-*-p-*-iso8859-15" to type FontStruct

    Solution:

    The problem is LC_CTYPE=en_GB.ISO8859-15, for some reason when added to your users profile i.e. websphere unix user e.g wasadm it causes the xwindows java program to error.

    If you are not able to change the profile, you can use

    unset LC_CTYPE

    This will clear the environment variable.

    ---------------------------- or ----------------------------

    An excerpt from a Solaris websphere unix profile shows where we commented out the LC_CTYPE=en_GB.ISO8859-15 line and found it solved the problem.

    #!/usr/bin/ksh
    #**********************************************************
    # .profile
    #**********************************************************

    #Begin Configuration Settings, these are for locale & character setting e.g currency symbols etc for GB
    TZ=GB
    CMASK=022
    LC_COLLATE=en_GB.ISO8859-15
    #LC_CTYPE=en_GB.ISO8859-15
    LC_MESSAGES=C
    LC_MONETARY=en_GB.ISO8859-15
    LC_NUMERIC=en_GB.ISO8859-15
    LC_TIME=en_GB.ISO8859-15
    export TZ CMASK LC_COLLATE LC_CTYPE LC_MESSAGES LC_MONETARY LC_NUMERIC LC_TIME
    #End Configuration Settings
