Hi,
the only thing I have done till now is to deploy the InterestBean from the

deploying interest.jar
Now I have tried to access that bean with the following client. The
JNDI -Name of my bean is Interest
public static void main(java.lang.String[] args) {
// Insert code to start the application here.
try {
Properties p = System.getProperties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
org.jnp.interfaces.NamingContextFactory);
p.put(Context.PROVIDER_URL, localhost:1099);
p.put(Context.URL_PKG_PREFIXES, org.jboss.naming:org.jnp.interfaces);
InitialContext jndiContext = new InitialContext(p);
System.out.println(Got context);
// Get a reference to the Interest Bean
Object ref = jndiContext.lookup(Interest);
System.out.println(Got reference);
} catch (Exception e) {
e.printStackTrace();
}
}
If I run that client I get the following exception:
javax.naming.CommunicationException. Root exception is
java.io.StreamCorruptedException: Type code out of range, is 125
My guess is that the client and server is not running the same Java
version. I know that if you've got a 1.2 client and a 1.3 server you get
this exception. There is some system property you can set to get the 1.3
VM to run as 1.2. Search the archive for, it's in there somewhere.

There will be a problem here since unless there was an SQLException
earlier the resultSet will be closed. The Statement.close() method also
closes the ResultSet. Come to think of it, the statement has gone out of
scope and cannot be relied on so the ResultSet is probably going to be
closed anyway.
Why do you want to return the id if there was an SQLException? The finally
block is executed whenever and however you leave the try/catch block
(save perhaps for System.exit() ;).
BTW...A common way to deal with sql queries is to move the calls to
close() methods to the finally block.

try { stmt.close(); } catch(Exception e) {}

Re: [JBoss-user] Stateless Session Bean and CallableStatement
On Wed, 23 May 2001, Dave, Pragnesh wrote: Greetings ! David, thanks for pointing that the CallableStatement doesn't implement Serializable. I checked the docs and got the same info; I got confused as I was previously using VAJ and websphere and the data connector-DAB extension allows to Serialize CallableStatement; basically IBM extended the CallableStatement and implemented Serializable. In one the articles at developerworks, Cynthia Saracco actually says that wrapping DBMS stored proc under stateless session beans is a good idea and passing the Serialized CallableStatement back to the client a better approach then creating your own Collection. http://www-106.ibm.com/developerworks/components/library/j-spejb/?dwzone=com ponents (I didn't bother reading the article ;) I guess the reason for passing the CallableStatement to the client is that you don't want to first unroll the ResultSet, put it into a Collection and then pass that Collection to the client who has to iterate it again. If the CallableStatement does not produce a ResultSet then there would be no point. You could use a Stateful Session Bean instead and store the ResultSet in the bean and add a method that gets the next row from the ResultSet. The more beautiful solution would be to implement a Serializable iterator and pass that back to the client. The next() method in the iterator would get the next row from the Session Bean.

Re: [JBoss-user] Stateless Session Bean and CallableStatement
On Wed, 23 May 2001, Guy Rouillier wrote: I also didn't read the article, but in my not so humble opinion, this is ** terrible ** advice. Keeping a database statement (and hence connection) open for use by a client is just asking for trouble in a network environment. First is the pandora's box of possible failure points in the point-to-point connection. But even if you have a perfect network, you have no idea what the caller is going to do with that statement. He may do nothing and just sit on it for the next 3 weeks! I read the other response to this post, and I don't think allow remote iteration to a collection is a good idea for similar reasons. You want to design your system to maximize robustness, concurrency and performance. All of these benefit from finishing a logical unit of work completely in a single method before returning to the client. We've opted to serialize our database results into an xml string, close the db connection (which returns it to the pool) and then send the xml string back to the client. You're absolutely right. I'll have to back down on my suggested solution (remote iteration). It was more of a work-around really, but you're right. Don't let the clients near the database.

There's very little context here, but it seems as though you try to use
the SessionContext for a JNDI lookup. The SessionContext is not a JNDI
context. You should probably do the following instead:
InitialContext ic = new InitialContext();
MassnahmeHome m_home = (MassnahmeHome)
ic.lookup(java:comp/env/entity/katalog/Massnahme);

Re: New: [JBoss-user] MDB...why?
I seemed to have ranted abit, but I hope you'll find this useful. On Mon, 14 May 2001 [EMAIL PROTECTED] wrote: (Excuse me if this e-mail appears twice) Thank you Per!! The origin of this confusion is a sample in JBoss Documentation, making more specific: example called MDB as a Listener. How many subscribers appear in this example? One. The ListernerBean is the one subscriber to the Topic topic/testTopic. I think a subscriber is 'Worker Bean', isn't it? The subscriber is the ListernerBean. When the listener bean receives a message it calls the WorkerBean. Then, to have more than one subscriber i've to create other Beans similar (or not) to Worker Bean, haven't i? (I see know why you talked about using a Topic in your last mail (that's what's great about helping others, innit?). The reason for using a topic is to be able to send an event to many event listeners.) The Worker bean is an ordinary Session Bean and is not directly involved in the JMS thingy. Lets call a message published on the topic a WorkEvent that triggers that work should be done (man, I'd hate one of those ;). In the example the ListenerBean receives that event and instead of doing the work himself he delegates (sweet) it to the WorkerBean. If you'd want more beans to listen to that event then yes, you'd have to modify the ListenerBean to also call those other beans. The idea is that there should be one Topic for all events and that the ListenerBean is responisble for sending events on to other beans (the actual listeners, so to speak). I'd say that the idea is a little lost in the example as it is too simple. The advantage of having one Topic and one subscriber is that you only have to reconfigure that subscriber, something which could be done via the environment. The advantage doesn't really become apparent when you have only one event; you could just attach many MDBs to that Topic. However, when you want to add more events you'd have to add more Topics and that would require restarting the server (right now, Topics added while the server is running are not recreated when the server is restarted (are they?)). So, if i create new beans i have to modify my Listener to be able to comunicate with the new subscriber... Yes. Please, am i in the correct way? You are. Cheers On Mon, 14 May 2001 [EMAIL PROTECTED] wrote: Hi: I'm testing JBoss with MDB but i'm still lost about its utility... I'd like to write an application to manage a little web-shop using EJBs and MDBs as follows: * A java servlet who takes data from web application, i.e. the identifier of a client who wants to buy a book. * Before allowing this purchase i want to check if this client is not in my 'defaulter list'. * After this i'll be able to avoid/allow the purchase. Well, i though to do this: The servlet takes data from web client and sends it to a Topic, then Topic sends data to a Checker Bean that runs a method called 'checkClient' wich look for this client in a 'defaulter' database. If everything is ok, a 'true' value is returned to servlet Sounds more like a Queue than a Topic to me. Queues are for point-to-point messages and Topics are for Publisher/Subscriber (many receivers). Is this a good way to pose my problem? I know its possible to develope *the same* without MDBs, but, is there any advantage on using MDBs? in other words, how can i take advantage of MDBs? I'm not sure what you are trying to do, but this is my take on what you want. 0. MDB listens for messages on in queue 1. serlvet sends message to in queue with whatever should be checked 2. servlet waits for message on out queue 3. MDB.onMessage() called 4. MDB checks whatever 5. MDB sends message (true or false) to out queue 6. servlet receives message and proceeds I'd say that the advantage of MDBs is that they can be called asynchronously. What you want to do sound synchronous and while possible to do it just adds a lot of overhead. A session bean is easier and faster. To me it seems as though MDBs are useful for triggering some action that you don't want to hang around waiting for. For instance, you might want to send an email with an order confirmation and personally I wouldn't want to hang around in my process order session bean waiting for JavaMail to finish (after all it is talking SMTP to a mail server somewhere) so I would simple put a message in a queue and let an MDB deal with the sending of emails.
