Hi all, I created a jar file using the following ANT script

<manifestclasspath property="jar.classpath" jarfile="${bin.dir}/${jar.app.name}" maxparentlevels="0">
    <classpath refid="main.class.path" />
</manifestclasspath>
<target name="jar">
    <mkdir dir="${build.dir}/lib/isp"/>
    <mkdir dir="${build.dir}/lib/jasper"/>
    <copy todir="${build.dir}/lib/jasper">
            <fileset dir="${lib.jasper.dir}">
                    <include name="**/*.jar" />
            </fileset>
    </copy>
    <copy todir="${build.dir}/lib/isp">
            <fileset dir="${lib.isp.dir}">
                    <include name="**/*.jar" />
            </fileset>
    </copy>
    <jar jarfile="${bin.dir}/${jar.app.name}"
            index="true"
            basedir="${classes.dir}" excludes="lib/mytest.jar "
            >
            <manifest>
                    <attribute name="Main-Class" value="${main.class}" />
                    <attribute name="Class-Path" value="${jar.classpath}" />
            </manifest>
    </jar>
</target>

The resulting jar file has the following MANIFEST.MF entry.

Main-Class: dm.jb.Main
Class-Path: lib/isp/OfficeLnFs_2.2.jar lib/isp/RXTXcomm.jar lib/isp/ba
rbecue-1.0.6d.jar lib/isp/commons-logging-1.1.jar lib/isp/forms-1.0.5

ar lib/isp/mssqlserver.jar lib/isp/msutil.jar lib/isp/mysql-connector

When I try to run the command java -jar mytest.jar, it fails and throws error saying dm.jb.Main not found. But I could run the class by specifying the classpath java -classpath dm.jb.Main

Please help me DM
