Building weblogic ejbs with ant...

Question

Hi, it may be not the proper place, but I haven't found a better one...
Here comes my question:
I have an ant build.xml file where I have the following tasks defined:
<property name="ejb.dtd.location" value="weblogic/ejb/deployment/xml/ejb-jar.dtd"/>
    <condition property="ejb.dtd.location" value="weblogic/ejb20/dd/xml/ejb11-jar.dtd">
      <equals arg1="${weblogic.major.version}" arg2="6"/>
    </condition>
    <property name="weblogic.ejb.dtd.location" value="weblogic/ejb/deployment/xml/weblogic-ejb-jar.dtd"/>
    <condition property="ejb.dtd.location" value="weblogic/ejb20/dd/xml/weblogic510-ejb-jar.dtd">
      <equals arg1="${weblogic.major.version}" arg2="6"/>
    </condition>
<!-- compiles EJBs -->
  <target name="compile.ejb" depends="init">
    <javac srcdir="${srcDir.ejb}"
          destdir="${srcDir.ejb}"
            debug="${npm.debug}">
      <classpath id="ejb.cpath">
         <pathelement path="${weblogic.sp.path}"/>
         <pathelement path="${weblogic.core.path}"/>
         <pathelement location="${outDir.core}${file.separator}npm.jar"/>
         <pathelement location="${srcDir.ejb}"/>
       </classpath>
    </javac>
  </target>
  <!-- delivers EJBs -->
  <target name="make.ejb" depends="prepare, compile.ejb">
    <!-- ejbc 'n jar 'em -->
    <ejbjar srcdir="${srcDir.ejb}">
       <weblogic destdir="${outDir.ejb}"
                 compiler="${compiler.ejb}"
                 keepgeneric="false"
                 suffix=".jar"
                 args="-g -nowarn"
                 oldCMP="false">
         <classpath refid="ejb.cpath"/>
       </weblogic>
       <include name="**/*-ejb-jar.xml"/>
       <exclude name="**/*-weblogic-ejb-jar.xml"/>
       <!-- WLS v5 DTDs!!! -->
       <dtd publicId="-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN"
            location="${ejb.dtd.location}"/>
       <dtd publicId="-//BEA Systems, Inc.//DTD WebLogic 5.1.0 EJB//EN"
            location="${weblogic.ejb.dtd.location}"/>
    </ejbjar>
  </target>This should build my ejbs with either the wls61 ejbc or the wls51 one. Anyway ant seems to have problems finding the local dtds in the classpath, although this is specified in the documentation. When I set both location attributes to point to files it works perfect. The problem is that these are in weblogic.jar for the wls61 release. This has two solutions, but either are bad in my opinion:
1. extract the needed dtds to a temp dir with a jar task and then delete em...
2. put the proper wls.jar in the classpath so ejbc could automatically resolve the dtds
Can anyone help or may be send his ant build file, where a <dtd> nested element is used for <ejbjar> for wls61?
Thank you in advance
Anton

Answer 1

Anton,
Your second solution is the correct one. If you look at dtd element description under ejbjar task in the Ant manual, you'll see that vendors jars are required in Ant's classpath in order for ejbjar task to resolve DTD dependencies, in which case you don't need to specify dtd elements. I don't particularly like it either. If you find a better way to solve this problem, let me know.
