Subject Re: persistent problems with Ant
Date Mon, 22 Jan 2001 13:35:43 GMT
Try looking in at .java_wrapper in the bin directory of the jdk/jre
installation.  It sets JAVA_HOME under some conditions, and can cause
trouble.  The change below cured my problem, although looking at it now,
I'm not quite sure why or how...:)
 
Look in .java_wrapper for

if [ -z "$JAVA_HOME" ] ; then
    export JAVA_HOME
    JAVA_HOME=$J_HOME
fi

and replace it with

# if [ -z "$JAVA_HOME" ] ; then
    export JAVA_HOME
    JAVA_HOME=$J_HOME
# fi
