[JBoss-user] [Installation, Configuration & Deployment] - Configure log4j email appender
Hi, I've successfully configured my log4j.xml to send emails whenever any ERROR or FATAL log message occurs. It works great, except that when something nasty happens we often get hundreds or sometimes thousands of emails! I'd like to get the number of emails down to something manageable so that we can be paged when an error condition occurs. We did contact JBoss support, and they recommended writing a custom Filter, but that's proving to be a bit tricky to remember the previous log messages in a given timeframe (sorry, we're new). Searching the net, I've stumbling across a few mentions of combining the AsyncAppender with the SMTPAppender somehow to deal with my exact problem. Though, I couldn't find any detailed conversation or examples. Does anyone know if the AsyncAppender can be used to somehow cut down on the number of redundant emails (emails with the same error message, but different timestamp)? I'm sure we're not the first ones to want less than hundreds of emails within a few minutes. ;-) If anyone can point me in the write direction of where to look or even share some quick configuration or Filter examples, that sure would be appreciated. Thank you! I'm using JBoss 4.0.3SP1 on Solaris.

[JBoss-user] [EJB/JBoss] - Re: Stateless Session Bean versus static method calls
Okay, I did manage to find one thread discussing a similar topic. The original poster basically had the same question. There's good conversation here explaining that the singleton or static class approach IS a good idea. http://forum.java.sun.com/thread.jspa?threadID=555658&tstart=255 However, I'm still confused on when it's a good idea to use a Stateless Session Bean. When is it better to use a Stateless Session Bean versus a static class? Thanks for clarification.

[JBoss-user] [EJB/JBoss] - Stateless Session Bean versus static method calls
Hi, I have managed to get myself confused over when to use Stateless Session Beans versus just making calls to static methods. I know there's lots of documentation about when to use Session Beans, but I haven't found anything discussing this particular comparison. I'm hoping someone can help me get my head around this because I'm pretty new to J2EE. Thanks. I am working on a middleware system that basically routes messages between several applications state-wide, and indirectly nation-wide. I wanted to write two classes. One uses Hibernate to store each message in the database as it passes through the middleware. Then when all the responses for a request come in, this class will pass the message bundle to my second class, a router. The router class is meant to do some minor security and then send the message bundle off to the proper destination. I had originally thought these two classes would just be Stateless Session Beans that would be invoked from an MDB when a new message reaches my JMS Queue. However, our consultant thought it would be a far better idea to use a class with static methods instead of Stateless Session Beans. Because these classes do not have state information, the static approach should work, he said. The static approach would supposedly use less memory because there are no beans (other than the MDBs) being pooled, and only one instance would be in memory. He claims there will be no concurrency issues because an MDB can still call a static method without worry of when the other MDBs call the static method. Again, the methods are stateless, and supposedly no MDB would block waiting for another MDB to finish (just like how anyone can call System.out.println() without worry that some other class called it at the same time). All of that sounds fairly reasonable, but now I've got myself confused. With this in mind, why does anyone ever use Stateless Session Beans? I hope that doesn't sound accusatory. I'm certain that Sun know what they're doing! ;-) I'm just confused. The one benefit is JNDI look-ups, obviously, but if the beans are going to be on the same box is there any reason to use the Stateless Session Beans? Please help! I've gotten myself confused and I'm sure I'm just having a brain freeze here. Anyone who can set me straight would be GREATLY appreciated, so that I understand when I should use a Stateless Session Bean, and what the trade-offs are for these two approaches. If I need to better explain anything, just let me know. I have commercial support too, but I hate to bother JBoss with something that is probably so obvious to those of you with more experienced. Thanks!

[JBoss-user] [Messaging, JMS & JBossMQ] - Re: Number of Mbean instances in pool
If you look into conf/standardjboss.xml, you'll find a section on message-driven-bean. In here you can set the MinimumSize and MaximumSize Here's a snippet from my file: | | message-driven-bean | default | org.jboss.ejb.plugins.jms.JMSContainerInvoker | | DefaultJMSProvider | StdJMSPool | | 1 | 15 | 3 | 1 | | 10 | | queue/DLQ | 10 | 0 | | | | I'm pretty new to JBoss, so there may be better ways of doing this. For example, you can change these settings using the jmx-console (look under jboss.j2ee). However, changes done in jmx-console are not permanent. You're settings will return to the default when you next restart JBoss. If anyone can add to this, that would be greatly appreciated. For example, I would like to learn more about how we determine exactly how many MDBs are running at a given time.

[JBoss-user] [Messaging, JMS & JBossMQ] - Re: Persistent messages not being deleted
PROBLEM RESOLVED Sorry, I have resolved my problem. The problem was that another developer and I were usingdifferent subscription-id's when testing our MDB. This created two subscriptions in our JMS_SUBSCRIPTIONS table, causing the Topic to attempt delivery to both subscriptions. Because we only ran one MDB with one of the subscription-id's at any given time, messages would stack in the database due to the lack of a listener for one of the subscription-id's. This is a non-issue. The topic did exactly what it was supposed to do. We were just confused because we didn't expect two subscriptions. Sorry!

[JBoss-user] [Messaging, JMS & JBossMQ] - Re: JBossMQ performance
Hi. I'm a newbie to JBoss (well, J2EE for that matter), so please forgive me if you've already tried this. In the jmx-console, under jboss.j2ee, you can play with the minimum and maximum number of MDBs. Can you try increasing those to see if that makes any difference? Unfortunately, I haven't found how to make this change permanent, but at least this would give us some idea if the number of MDB instances is the bottleneck. Also, you can increase the maximum memory used by JBoss in bin/run.conf. This could potentially improve performance a bit as well. I hope that helps.

[JBoss-user] [Messaging, JMS & JBossMQ] - Persistent messages not being deleted
Hi, About a week ago, our persistent messages for a prototype we're developing stopped working properly. Messages are written to the database, but are never deleted. An MDB receives the message and processes it properly, but the message is never deleted from the database. We're using JBoss 4.0. Oracle 9.2.0.3 is used to store the persistent messages. I've tried using AUTO_ACKNOWLEDGE and CLIENT_ACKNOWLEDGE, both with the same results. I've been trying to determine what has changed in my environment for this last week, but I have been unable to find it. Does anyone have any ideas that I might try? I'm stumped! Thank you.

Yes, and it turns out that AUTO_ACKNOWLEDGE is already doing what I want it to do. AUTO_ACKNOWLEDGE is meant to send the ack at the end of the onMessage() method, so that actually meets my needs.

I believe I have resolved my issue. The trick is to use the CLIENT_ACKNOWLEDGE. I believe the default is AUTO_ACKNOWLEDGE. This should work with any subscriber, but for an MDB, I just needed to add CLIENT_ACKNOWLEDGE to my ejb-jar.xml, add a Message.acknowledge(); to my onMessage() within the MDB, and modify my creation of the session to be topicConnection.createTopicSession(false, Session.CLIENT_ACKNOWLEDGE); For more information, see the following links: http://docs.jboss.org/admin-devel/Chap6.html http://java.sun.com/j2ee/1.4/docs/api/javax/jms/Session.html#CLIENT_ACKNOWLEDGE View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3853943#3853943 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3853943 --- This SF.Net email is sponsored by: Sybase ASE Linux Express Edition - download now for FREE LinuxWorld Reader's Choice Award Winner for best database on Linux. http://ads.osdn.com/?ad_id=5588&alloc_id=12065&op=click ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

Hi, I am using JBoss 4.0 on Solaris 9 with a 4 CPU sparc 450 MHz and 4 Gigs of RAM. I'm sorry if this is a silly question, but I am confused about the jms invoker. According to http://www.jboss.org/wiki/Wiki.jsp?page=ConfigJBoss4MDB deploy/jms/jms-ra.rar is experimental. I am trying to understand the documentation on this, but I must not be looking in the right places. Please help! I am experiencing problems where under heavy load not all of my messages are being delivered. Is jms-ra.rar the only invoker included with JBoss 4.0? If not, what else can I use? Is jms-ra.rar the default? When I look in my conf/standardjboss.xml I see is just set to default. If jms-ra.rar is my only option, are there recommendations for what I should do if I will use JBoss 4.0 in a production JMS-heavy application? Thanks for the help. I'm very confused.

Another angle that would work for solving my problem is if there is any way to store the message persistently before the MDB (or any other subscriber) returns the ack to the topic. Is there any way to do that? Can anyone point me in the right direction on where to read about this problem? By the way, if I need to use queues instead of topics to make this happen, I would be interested in hearing about that as well. If anyone can help, it would be GREATLY appreciated. Thank you!

[JBoss-user] [Messaging, JMS & JBossMQ] - Re: Where is the storage for JBossMQ?
I'm pretty new to JBoss myself, but it's my understanding that the message will just reside in memory unless you actually make it persistent. For instructions on making your JMS persistent, see: http://www.jboss.org/wiki/Wiki.jsp?page=DeliveryMode And you'll most definitely want to change what database is used. The default database is included as an example only and is not meant for production use. You can get instructions for changing the underlying database here: http://www.jboss.org/wiki/Wiki.jsp?page=ConfigJBossMQDB http://www.jboss.org/wiki/Wiki.jsp?page=ConfigJBossMQJDBC2Persistence However, I found the instructions for changing the database in the Getting Started guide to be even better.

To expand, the following is the scenario I desire: 1. A message is posted to a persistent topic 2. An MDB reads the message and does it's business logic (the MDB may be across the network) 3. The client application stores the message persistently before doing anything else 4. The client application sends an acknowledgement to the server stating that the message was received 5. The server receives the acknowledgement 6. The server marks the message in the topic for deletion 7.

[JBoss-user] [Messaging, JMS & JBossMQ] - Persistence - control the marking of messages to be deleted
Hi: Is there any way to control when a message gets marked for deletion in JBoss 4.0's persistent JMS? When my MDB reads a message from the persistent topic, the message seems to be immediately marked for deletion and deleted. (Right now the MDB is the only thing subscribed to the topic.) This is probably perfect behavior for most systems, but I would like the message to stay on the topic until I mark it for deletion. It is possible that the MDB could read the message causing the message to be deleted, and then the system could crash before the MDB passes the message over the network to the client. Because of my critical need for persistence, I can't take that risk. I've been trying for several days now to go through the online JBoss and Sun J2EE documentation. I'm pretty new to Java and J2EE, so please forgive me if I'm overlooking something obvious. Can anyone help me out? Or point me in the right direction for what configuration I should be reading about? Maybe I could code something myself instead of using JMS, but I hate to reinvent the wheel when programmers far better than I have likely already done this in J2EE. We're in the process of purchasing JBoss support, but a headstart from people in the public forums would be appreciated. Thanks!

[JBoss-user] [Installation & Configuration] - Re: AOP classes not found in JBoss 4
I am also having the problems. It's odd to me that this would happen just as a result of using the "default" configuration instead of the "all" configuration. Is there some sort of services file or something that I have misconfigured that's telling JBoss to start AspectManager even though it's supposedly not available in the "default" configuration? I had tried running JBoss 4 as a test on a Windows machine and didn't have that problem. I'm somehow something must be telling JBoss 4 to attempt starting the AspectManager service. I'll just run with "all" for now, but I would like to learn what is causing this. Thanks.
