The following wrapper script (xyz) sets a few environment variables and accepts command line options:
#!/bin/sh CPATH=/mydir/myclass:/mydir/myjar.jar; export CPATH JARGS="-verbose:gc -verbose:jni -DXYZ=/mydir/xyz" ARGS= while [ $# -gt 0 ] ; do case "$1" in -userdir) shift; if [ $# -gt 0 ] ; then userdir=$1; fi;; -J*) jopt=`expr $1 : ’-J<.*>’` ; JARGS="$JARGS ’$jopt’";; *) ARGS="$ARGS ’$1’" ;; esac shift done java $JARGS -cp $CPATH $ARGS |
This script accepts some command line options for the JVM software and the user application. For wrapper scripts of this form, you would set the jvm_invocation environment variable and start dbx as follows:
% jvm_invocation="xyz -J-Xdebug -Jany other java options" % dbx myclass.class -Dide=visual |
