ant targets

[Jim Dowling]

Monty,
I'm at a loss as to how I get java to find the relevant JNI shared library.
Normally, i could set LD_LIBRARY_PATH or java.library.path, and JNI  
would find and load the shared library.
However, it's not happening with swig:

jdowling@localhost:~/dev/ndbconnectors/devel/java$ env | grep LD_LI

LD_LIBRARY_PATH=:/home/jdowling/.mysql/mysql/lib:/usr/local/lib
jdowling@localhost:~/dev/ndbconnectors/devel/java$ ls 
/usr/local/lib/libndbj.*
/usr/local/lib/libndbj.a   /usr/local/lib/libndbj.so.0
/usr/local/lib/libndbj.la  /usr/local/lib/libndbj.so.0.0.0
/usr/local/lib/libndbj.so

Modified ant target to include java.library.path:
  <target name="HelloWorldInsert">
    <java fork="yes" 
classname="com.mysql.cluster.ndbj.examples.HelloWorldInsert" 
failonerror="true">
      <classpath refid="NdbConnectors.classpath"/>
        <arg value="-Djava.library.path=/home/jdowling/.mysql/mysql/lib"/>
    </java>
  </target>

jdowling@localhost:~/dev/ndbconnectors/devel/java$ ant HelloWorldInsert
Buildfile: build.xml

HelloWorldInsert:

Any ideas what I'm doing wrong?
