      Now it seems to me that i solved it by inserting in the file standardjboss.xml this string:

      <!--<interceptor call-by-value="false">org.jboss.invocation.InvokerInterceptor</interceptor>-->
      <interceptor call-by-value="false">org.jboss.invocation.ByValueInvokerInterceptor</interceptor>


      But by doing so i have the classic exception principal=null; i post here this exception:

      * sent by the client. Instance pooling within the container means that messages are not
      * received or processed in a sequential order, although individual onMessage() calls to
      * a given message-driven bean instance are serialized.
      *
      * <p>The <code>onMessage()</code> method is required, and must take a single parameter
      * of type javax.jms.Message. The throws clause (if used) must not include an application
      * exception. Must not be declared as final or static.
