--------------------------------------------------------------
I have found a workaround for this problem by my own.

I have added a response handler to the webservice that add a dummy attachment part to the soap message and activate mtom using the method org.jboss.ws.extensions.xop.XOPContext#setMTOMEnabled(true) and declare the message as a XOP Message. That's all.

*Code Sample:*

public boolean handleMessage( MessageContext msgContext ) {
....
... +// decide if outbound and other code left out+....
....

     org.jboss.ws.core.soap.SOAPMessage msg = ((SOAPMessageContext) msgContext).getMessage();
     org.jboss.ws.core.CommonMessageContext cmCtx = (org.jboss.ws.core.CommonMessageContext) msgContext;

     ByteArrayDataSource DUMMY_PLAIN_DATA_SOURCE;
     DUMMY_PLAIN_DATA_SOURCE = new ByteArrayDataSource( "DUMMY_ATTACHMENT_TO_FORCE_MTOM_RESPONSE", "text/plain" );
*msg.addAttachmentPart( msg.createAttachmentPart( new DataHandler( DUMMY_PLAIN_DATA_SOURCE ) ) );*
 *((SOAPMessageImpl) msg).setXOPMessage( true );*
     Scope lastScope = cmCtx.getCurrentScope();
     cmCtx.setCurrentScope( Scope.APPLICATION );
*XOPContext.setMTOMEnabled( true );*
     cmCtx.setCurrentScope( lastScope );
...
}
