EJB JAR building by ANT problem

Question

I have this task in my build file:
[code]
<target name="build"
     depends="compile">
        <ejbjar srcdir="$"
          descriptordir="META-INF"
          destdir="$"
          >
     </ejbjar>
</target> 
[/code]
which is generating this error message:
build:
      [ejbjar] Unable to load dependency analyzer: org.apache.tools.ant.util.depend.bcel.AncestorAnalyzer - dependent class not found: org/apache/bcel/classfile/ClassParser
      [ejbjar] BUILD FAILED: file:d:/my projects/MyApp/Bean/build.xml:82: SAXException while parsing 'ejb-j2ee-engine.xml'. This probably indicates badly-formed XML.  Details: Relative URI "ejb-j2ee-engine.dtd"; can not be resolved without a base URI.

Answer 1

Well, for the time being this is my solution:
[code]
<target name="build"
     depends="compile">
   <zip destfile="${ant.project.name}.jar">
     <fileset dir="$" />
     <fileset dir="$"
            includes="META-INF/**"/>
   </zip>
</target> 
[/code]
The resulting jar file has the same contents as the jar which is produced by the Netw. Dev. Studio
