> Hello,
> I have a trouble on weblogic server (I'm using the axis client part).
> The stack trace is :

> umentBuilder.java:168)
>         at org.apache.axis.utils.XMLUtils.releaseDocumentBuilder(XMLUtils.java:235
>  
> It's caused by the :
>     public static void releaseDocumentBuilder(DocumentBuilder db) {
>         synchronized (documentBuilders) {
>             db.setErrorHandler(null); // setting implementation default
>             db.setEntityResolver(null); // setting implementation default
>             documentBuilders.push(db);
>         }
>     }

> Whereas the 1.2-RC1 contains :
>  
>     public static Document newDocument(InputSource inp)
>         throws ParserConfigurationException, SAXException, IOException
>     {
>         DocumentBuilder db;

>         db.setEntityResolver(new DefaultEntityResolver());
>         db.setErrorHandler( new ParserErrorHandler() );
>         return( db.parse( inp ) );
>     }
>  
> How is right ?? 
>  
> Furthermore I have the stack trace with 1.2-RC1 :
> java.lang.IncompatibleClassChangeError 
>         at org.apache.axis.message.MessageElement.addTextNode(MessageElement.java:1388)

> The structure in the weblo exploded ear is the following :
>  
> exploded
>     APP-INF/lib
>         contains all jars (axis, axis-stubs and mine)
>     MyWebApp1    
>         /lib (empty)
>     MyWebApp2
>         /lib (empty)
>  
> To correct this, I need to put the axis-saaj-1.2-RC1.jar in the weblogic classpath in
the position.
> Is there other way to correct this ?

> Thanks a lot,
