After building your kernel to support binfmt_misc, cat the following line
to /proc/sys/fs/binfmt_misc/register
:Java:M::\xca\xfe\xba\xbe::/usr/local/bin/jwrapper:
and make an executable file /usr/local/bin/jwrapper containing the script
which follows :
-----BEGIN JWRAPPER-----
#!/bin/bash
# /usr/local/bin/jwrapper - the wrapper for binfmt_misc/java
CLASS=$1
# if classname is a link, we follow it (this could be done easier - how?)
if [ -L "$1" ] ; then
CLASS=`ls --color=no -l $1 | tr -s '\t ' ' ' | cut -d ' ' -f 11`
fi
CLASSN=`basename $CLASS .class`
CLASSP=`dirname $CLASS`
FOO=$PATH
PATH=$CLASSPATH
if [ -z "`type -p -a $CLASSN.class`" ] ; then
# class is not in CLASSPATH
if [ -e "$CLASSP/$CLASSN.class" ] ; then
# append dir of class to CLASSPATH
if [ -z "${CLASSPATH}" ] ; then
export CLASSPATH=$CLASSP
else
export CLASSPATH=$CLASSP:$CLASSPATH
fi
else
# uh! now we would have to create a symbolic link - really
# ugly, i.e. print a message that one has to change the setup
echo "Hey! This is not a good setup to run $1 !"
exit 1
fi
fi
PATH=$FOO
shift
/opt/jdk/bin/java $CLASSN "$@"
-----END JWRAPPER-----
