java - Ant apache and Native Libraries -

i trying use ant apache build project. however, whenever try typing in "ant" start building, error message shows on terminal:

 [java] exception in thread "main" java.lang.unsatisfiedlinkerror: no em1dfwdjava in java.library.path  [java]     @ java.lang.classloader.loadlibrary(classloader.java:1860)  [java]     @ java.lang.runtime.loadlibrary0(runtime.java:845)  [java]     @ java.lang.system.loadlibrary(system.java:1084) 

the strange thing is, when run em1dfwdjava.java, compiles , runs normal. em1dfwdjava.java uses loadlibrary native library. project, using 2 libraries, libem.dylib , dipole.dylib. believe there possibility need include 2 libraries in build.xml. if so, not sure include 2 libraries without messing build. below build.xml using:

    <project name='jppf application' basedir="." default="run">      <property name="build.properties.file" value="${basedir}/build.properties"/>   <property file="${build.properties.file}"/>     <property name="lib.dir"    value="${basedir}/lib"/>     <property name="config.dir"  value="${basedir}/config"/>     <property name="classes.dir" value="${basedir}/classes"/>        <property name="src.dir"     value="${basedir}/src"/>       <path id="project.classpath">         <pathelement location="${config.dir}"/>         <pathelement location="${classes.dir}"/>         <fileset dir="${lib.dir}" includes="**/*.jar"/>     </path>       <target name="clean">         <delete dir="${classes.dir}" quiet="true"/>     </target>                      <target name="init" description="initialize ressources">         <mkdir dir="${classes.dir}"/>     </target>       <target name="compile" depends="clean, init">         <javac srcdir="" destdir="${classes.dir}"             debug="on" deprecation="off" optimize="on" includes="**/*.java">         <classpath refid="project.classpath"/>         <compilerarg line="-xlint:unchecked"/>             <src path="${src.dir}"/>         </javac>     </target>       <target name="build" description="build application" depends="clean, init, compile">         <mkdir dir="${classes.dir}"/>     </target>       <target name="run" description="run application" depends="build">         <java fork="yes" classname="${main.class}" classpathref="project.classpath">             <jvmarg value="-djppf.config=jppf.properties"/>             <jvmarg value="-djava.util.logging.config.file=config/logging.properties"/>             <jvmarg value="-xmx64m"/>         </java>     </target>      </project>  

option 1: add java -djava.library.path="path em1dfwdjava"

option 2: add ld_library_path environmet variable path em1dfwdjava.
