    Error closing connection from a JSP. Why ?

      Hi all,
      I'm trying to send a JMS message from a JSP page.
      I have taken a basic TopicSendClient example and compiled
      it under WEB-INF/classes directory so that I can access it
      from a JSP

      package test;
      import javax.jms.*;
      import javax.naming.InitialContext;
      import javax.naming.NamingException;
      public class TopicSendClient
       TopicConnection conn = null;
       TopicSession session = null;
       Topic topic = null;
       public void setupPubSub(String queue)
       throws JMSException, NamingException
       InitialContext iniCtx = new InitialContext();
       Object tmp = iniCtx.lookup("java:/JmsXA");
       TopicConnectionFactory tcf = (TopicConnectionFactory) tmp;
       conn = tcf.createTopicConnection();
       topic = (Topic) iniCtx.lookup(queue);
       session = conn.createTopicSession(false,
       public void sendAsync(String text, String queue)
       throws JMSException, NamingException
       System.out.println("Begin sendAsync");
       // Setup the pub/sub connection, session
       // Send a text msg
       TopicPublisher send = session.createPublisher(topic);
       TextMessage tm = session.createTextMessage(text);
       System.out.println("sendAsync, sent text=" + tm.getText());
       System.out.println("End sendAsync");
       public void stop()
       throws JMSException

      The code is quite simple:

       test.TopicSendClient client = new test.TopicSendClient();
       client.sendAsync("A text msg","topic/testTopic");

      Unfortunately when the method conn.stop() is invoked JBoss issues this error:

      17:18:08,921 ERROR [Engine] StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception
      javax.jms.IllegalStateException: This method is not applicatable in JMS resource adapter at org.jboss.resource.adapter.jms.JmsSessionFactoryImpl.stop(JmsSessionF
      at test.TopicSendClient.stop(Unknown Source)
      at test.TopicSendClient.sendAsync(Unknown Source)

      at javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
      at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper

      Why JBoss raises this error ? Shouldn't I close the connection from a JSP or what ???
      Thanks a lot in advance
