title: Error using Ant to create EJB after upgrading WAS from 6.0 to 7.0
body: <p>Ant task breaks at the <code>&lt;wsejbdeploy&gt;</code> tag. The exception message is :</p>
  
  <pre><code>[wsejbdeploy] Error executing deployment: java.lang.ClassNotFoundException. 
  Error is com.ibm.etools.ejbdeploy.batch.plugin.BatchExtension.
  [wsejbdeploy] java.lang.ClassNotFoundException: 
  com.ibm.etools.ejbdeploy.batch.plugin.BatchExtension
  [wsejbdeploy]   at java.lang.Class.forName(Class.java:136)
  </code></pre>
  
  <p>In addition to that, ivy.xml reports problems, but when I inspect it, the messages have no sense (<a href="http://prntscr.com/1uy53" rel="nofollow">screenshot</a>). I suspect the problems could be:</p>
  
  <p>a) Additional files that I have for the build which conflict with the upgraded Ant (in RSA 7.0 i've had Ant 1.6.5 and RSA 8.0 comes with Ant 1.7.1). Additional files are:</p>
  
  <h2>required for ant tasks execution</h2>
  
  <ul>

  </ul>
  
  <p>b) Changes in the Ant regarding EJB build which require some settings to be reconfigured.</p>
  
  <p>c) Something else :)</p>
  
  <p>Except the Error, everything else is a stab in the dark so feel free to ask for any additional info.</p>
