title: What SAAJ package is used by WebLogic
body: <p>I have had many problems because there are different SAAJ packages with SOAP classes:</p>
  
  <ul>
  <li><code>com/sun/xml/internal/messaging/saaj/soap/</code>    in rt.jar</li>
  <li><code>com/sun/xml/messaging/saaj/soap/</code>               in saaj-impl.jar</li>
  </ul>
  
  <p>When WebLogic uses classes from <code>com/sun/xml/internal/messaging/saaj/soap/</code> and an application is created using classes from <code>com/sun/xml/messaging/saaj/soap/</code>, it throws exceptions like these when the app is deployed:</p>
  
  <p><code>com.sun.xml.internal.messaging.saaj.soap.LocalStrings != com.sun.xml.messaging.saaj.soap.LocalStrings</code></p>
  
  <p>or</p>
  
  <p><code>java.lang.NoClassDefFoundError: com/sun/xml/internal/messaging/saaj/soap/SAAJMetaFactoryImpl</code></p>
  
  <p>My solution was create a weblogic.xml descriptor with saaj reference and including saaj-impl.jar into the war.
  Question is: <strong>Can I know what SAAJ package is used in WebLogic Server?</strong></p>
