Hello, Can anyone tell me about the magic incantations to use so that a servlet in a web app can find the local interface of a session bean in a EJB where both are in the same Enterprise application (EAR file). Below is the detail.
Thank you in advance for your help Mho I am using tomcat 6.0.20 and openEJB 3.1.1 . (BTW I am using Eclipse J2EE Galileo as an IDE which even allowing for my lack of experties I think may have some issues of its own but this problem I am pretty sure is not caused by the IDE) To demonstrate this problem I have created a simple ear file that looks like this: http://www.nabble.com/file/p25310144/aif6_ear.jpg ext is a web app with a servlet "Agent" that just tries to talk to a session bean that is in an EJB called "service". So I load up the ext.war file and also aif6.ear file in Tomcat and restart Tomcat. ( Note: I need to load the war file separately because Catalina looks for the document root for web app in /ext. Naturally when the EAR file is expanded the document root is in /aif6/ext and Catalina throws an exception saying it cant find the web app. To make it happy I have to put the war file in the webapp directory. -- that is another problem that I will have to fix -- I am not sure this is related to the problem I am asking about in this email if anyone has a suggestion I will be grateful) The closest I have come to making this work is to use a snippet that I found in a previous response to someone in this forum. The Agen servlet has code in it that looks like this : Properties p = new Properties(); p.put("java.naming.factory.initial","org.apache.openejb.client.RemoteInitialContextFactory"); p.put("java.naming.provider.url", "http://127.0.0.1:8080/openejb/ejb";); initialContext = new InitialContext(p); try{ object = initialContext.lookup("ToDoSesBeanLocal"); }catch (Exception e){ logger.info("Cant open context "+e.toString()); return false; } (My specific question is about the counterpart to "java.naming.provider.url" that would let me use a local resource The EJB has a session bean with a local interface. When I run the servlet I get this exception: ****** Cant open context javax.naming.NamingException: Not remotable: 'ToDoSesBeanLocal'. Business Local interfaces are not remotable as per the EJB specification. To disable this restriction, set the system property 'openejb.remotable.businessLocals=true' in the server. It seems to me that doing what the exception says (BTW thank you openEJB folks for the very informative Exception) will create a remote interface but I should be able to hook this up with a local interface and avoid the overhead. to complete the picture let me outline the rest. The session bean is really a front for a MDB and it looks like this (some import stuff here) @Stateless(mappedName = "ToDoSesBeanMapped") public class ToDoSesBean implements ToDoSesBeanLocal { public ToDoSesBean() { // TODO Auto-generated constructor stub } @Resource private ConnectionFactory connectionFactory; @Resource(name = "ToDoBean") private Queue todoQueue; @Resource(name = "ToDo_AcknowlegeQueue") private Queue todo_acknowlegeQueue; public void sendMessage(String text) throws JMSException { Connection connection = null; Session session = null; try { connection = connectionFactory.createConnection(); connection.start(); // Create a Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); // Create a MessageProducer from the Session to the Topic or Queue MessageProducer producer = session.createProducer(todoQueue); producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT); (and so on...) The code snippet for the local test that works locally but for some reason does not work in the servlet looks like this Properties properties = new Properties(); properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,"org.apache.openejb.client.LocalInitialContextFactory"); InitialContext initialContext = new InitialContext(properties); Object object = initialContext.lookup("ToDoSesBeanLocal"); -- View this message in context: http://www.nabble.com/question-about-using-openEJB%2Btomcat-with-ear-file-tp25310144p25310144.html Sent from the OpenEJB User mailing list archive at Nabble.com.
