[JBoss-user] About JBoss HA: Simply curiosity
Hello: nowadays i'm testing High Availability with JBoss (http://194.38.95.241). I've installed and configured JBoss HA in two different PCs running Linux Mandrake 7.2. I've deployed the 'testbean.jar' and later i've run 5 instances of TestGUI.jar, and...it RUNS!!! : every node in the cluster is serving the same bean. But now i wonder: if i have configured NOWHERE the physical location of my Nodes, how JBoss HA can found each node in the cluster in our LAN? Perhaps is the 'JavaGroupsSettings' doing this job? Thanks in advance: P.D.: is HA project still alive?, i'm very interested on it. __ Jaume Soriano Sivera <[EMAIL PROTECTED]> Tel: 96504 -ext. 44744 Fax: 965040047 Portal y servicios multimedia - Nuevas tecnologias W a n a d o o E s p a n a - http://www.wanadoo.es __ ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
Re: [JBoss-user] MDB...why?
Hello Peter: Let's go with another example and you would say me if (now, at last, thanks god ;-) am i in the correct way: "An imaginary assumption: i wanna write an application to manage a Mail List in this way: Topic publisher side -- A servlet obtains a lot of information (news) about 'Sport', 'Cinema' and 'Computers'. This program sends messages to a Topic which include 'subject', 'theme' and 'body' fields. Topic subscriber side - Three (diferent) listeners called 'listenSport', 'listenCinema' and 'listenComputers' wait for a message with its 'theme' field equals to 'Sport', 'Cinema' or 'Computers', respectively. Each Listener will call outers Session Beans which transform the 'body' field in an HTML format (for Sports), PDF format (for Cinema) and Plain-text format (for Computers) and then, every Session Bean send an e-mail to [EMAIL PROTECTED], [EMAIL PROTECTED] or [EMAIL PROTECTED] with its respective attachment. Everything will occur without 'bothering' the servlet. In the other hand, writing 3 diferent Listeners will allow us to change (separately) the formating task asociated to each Listener, and, in the future, add new Listeners for new themes."

The ListenerBean is the subscriber. The logic is partitioned so that the work is done in the stateless session bean. Not that it is necesarry in this example, but only to show how it is possible to do it. When it commes to an MDB, you deploy one version (name, configuration) for each logic and topic/selector combination. Some areas to use this? - A time task run in JMX could send its task to a queue. An MDB listens for missions and delegate to a sessiion bean (or does the work for itself). - A bean get some cind of thing to do. To continue it need to wait one some cind of event (perhaps the presence of something). It triggers this and returns. A message bean listens on a queue where the event will be placed and calls the session bean (that perhaps has saves som temporary persistens data throug an entity bean from the earlier invokation, which it now uses. //Peter > > Please, am i in the correct way? > > Thank you again! > __ > Jaume Soriano Sivera <[EMAIL PROTECTED]> > __ > > > > > Per Lewau <[EMAIL PROTECTED]> > Sent by: [EMAIL PROTECTED] > 14/05/2001 13:08 > Please respond to jboss-user > > > To: [EMAIL PROTECTED] > cc: > Subject:Re: [JBoss-user] MDB...why? > > > > 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.

(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...

[JBoss-user] MDB...why?
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" 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? Excuse me if these questions sounds so 'simple' but i need a little help to understand MDB cause i'm really interested in learning everything about JBOSS.

RE: [JBoss-user] About TOPIC_FACTORY on MDB's sample (At last!! :-)
Well, it seems solved :)
In 'Main.java', method 'public static void main(String arg[])',
before the 'try{ ... }' sentence we should write the following:
System.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url","localhost:1099");
I think there are more ways to do the same, but it works!
Now i wonder:
is the 'Main.java' a wrong file? or perhaps,
did i forget any deployment file?

[JBoss-user] About TOPIC_FACTORY on MDB's sample (1 more time :)
Thank you Peter!...now i can compile my java file but i'm still having problems to run this example:
I suppose the 'TopicConnectionFactory' should be defined anywhere in the context...but, in which file?
and, how it looks?
When i try to run my compiled java file i get the following:
"javax.naming.NoInitialContextException: Need to specify class name in enviroment
or system property, or as an applet parameter, or in an application resource file:
java.naming.factory.initial
...
(and other java messages)
"
I think it is dued to the line:
...
TopicConnectionFactory tf = (TopicConnectionFactory) ctx.lookup("TopicConnectionFactory");
...
The JVM can't find this variable in the context, isn't it?
Perhaps i need to define 'something' else in 'jboss.jcml'?
Thanks a lot in advance!

Yes. Typicaly a static final String, ie
static final String TOPIC_FACTORY = "TopicConnectionFactory";
which I obviously missed to get when I ripped the example from some of
my programs. Sorry.

[JBoss-user] Error compiling MDB.java
Hello everybody: Nowadays i'm beggining with MDB in JBoss and to undersand how to implement it in my applications i've copied the MDB.java example from the JBoss documentation (Writing Message Driven Beans section).

Re: [JBoss-user] Interest Client Problems
Try this: java -classpath $CLASSPATH:$JBOSS_HOME/client/jboss-client.jar:$JBOSS_HOME/client/jbosssx-client.jar:. InterestClient * Note the ':.' after jbosssx-client.jar. * Replace my '$JBOSS_HOME' with your path to Jboss home and make sure you execute it at the same level of 'com' directory. (InterestClient will look for Interest and InterestHome in this path) *If you're trying to execute in a not-local-machine, first you must change the line 'localhost:1099' in your InterestClient.java to the appropiate URL.

[JBoss-user] Database Doubts
(thank you very much, Ralph) Another questions: I wanna use MySQL database to store data with JBoss. I have followed all the steps on the on-line documentation to configure JDBC and a Pool and, at this point i wonder: * which is the 'database name' that i must indicate in URL attribute? * does this database be created in MySql before being referenced in here? * ...if it runs: * does JBoss create the appropiate tables in this DB? * what is being saved in this database? * is this the DB used to manage entity beans (CMP)? Thanks in advance! Regards: Jaume
[JBoss-user] About InterestClient and interest.jar files
Hello: Nowadays, to run the client Interest Client for the Interest application in a remote machine i have to include the interest.jar file (the same as the file deployed on the JBoss Machine) or the structure of directorys 'com/web_tomorrow/interest/*.class' ...i supose that's not the right way to do it due to the "inteterest.jar" should be ONLY in the 'deploy' directory on JBoss Machine, isn't it? Here goes my questions: why i cannot run the client without the interest.jar file? what do i forgot to configure?
