Does Java2Wsdl support EJBs?

Does Java2Wsdl support WSDL generation from EJBs? I tried it but I am
getting the following exception:

WSDLException: faultCode=OTHER_ERROR: Can't find prefix for
'http://ejb.javax'.
            Namespace prefixes must be set on the Definition object
using the
            addNamespace(...) method.:

My ant build script is as follows (compile.path includes J2EE jars, thus
the javax.ejb package):

  <taskdef name="java2wsdl"
classname="org.apache.axis.tools.ant.wsdl.Java2WsdlAntTask">
    <classpath>
      <path refid="axis.path"/>
    </classpath>
  </taskdef>

  <target name="build-web-service">
    <java2wsdl
      classname="MyEjb"
      implclass="MyEjbBean"
      namespace="http://MyEjb"
      location="http://camnbhati:7001/soap/services/MyService"
      extraClasses=""
      output="${build.dir}/MyService.wsdl">
      <classpath>
        <path refid="compile.path"/>
        <pathelement location="${build.dir}"/>
      </classpath>
    </java2wsdl>
  </target>

Here's are the exception details from java2WSD:

Sorry if this is a dumb question, but why do you need Java2Wsdl?
