[JBoss-user] RE: Challenge for EJB-QL, JBossQL, or declared SQL?
I imagine ORDER BY is part of it, but the harder piece is getting the last sequence per batchnumber and THEN return that collection of objects (see example results below). Regular SQL would be something like SELECT batchnumber, MAX(sequence as MAX_sequence) FROM thetable ORDER BY batchnumber for JUST getting the last sequence number. You still have to do a JOIN or SUBSELECT from this query to attach to the actual search critera (item = foo or what-have-you). Then, the end result is still to return a collection of EJB local or remotes. Is there an elegant, object-oriented way of handling this kind of scenario? A 'J2EE' way of handling it? -D Subject: RE: [JBoss-user] Challenge for EJB-QL, JBossQL, or declared SQL? From: [EMAIL PROTECTED] Date: Thu, 6 Nov 2003 10:52:24 +0100 ORDER BY works in JBossQL.

[JBoss-user] Commit Option Confusion
Hi, I am tuning an app before deployment on 3.2.2. As this app 'owns' its own database and the DB is not that quick, I though that changing from the default commit option B to A should give me some improvements, but seems to make no difference. My tests complete in the same time with both option A and B, the SQL generated is identical with both options, and the CacheSize settings for the EJB's in the jmx-console are always Zero. I am missing something or is my understanding of Commit options flawed?

I'm sending several messages with different types to an mdb. One type stands for an update message. That means take the data from the message and update several entity beans with it. These updates have to be execute dstrictly serial. But it comes that more than one update message at the same time is send and jboss instantiates 2 or more mdb to execute the messages in parallel. How can I configure (or design?) my mdb that it exceute the messages of type update strictly one after the other. thanx sven CargoSoft GmbH Linzer Str. 3 28359 Bremen Telefon+49 421 2020 440 Telefax+49 421 2020 189 http://www.cargosoft.de eMail: [EMAIL PROTECTED] Hotline: [EMAIL PROTECTED] --- This SF.net email is sponsored by: SF.net Giveback Program.

[JBoss-user] CMP or BMP transactions, isolation level, performance
Greetings, I would like to ask if even with the CMP beans is possible to customize the transaction isolation level? If yes, how can I do it? I have an idea that CMP beans are the most light and fastest beans. But I think in the most of the times, we should have business logic in beans that requires synchronization. It stills worth going to CMP and lock the all bean operations or just go to BMP beans to use the programatic and customize the block of the transaction? regards, Pedro Salazar -- -PS --- This SF.net email is sponsored by: SF.net Giveback Program.

RE: [JBoss-user] RE: JMS problem?
Since the problem is with the client disconnecting, can configure log4j on the client? JBossMQ will log what is going on (i.e. why the client is disconnecting). You can also: QueueConnection qc = qcf.createQueueConnection(); qc.setExceptionListener(myExeptionListener); to catch a disconnection and reconnect. i.e. connection.close() - reinitialise the objects. Many people hide the jms api behind a wrapper to make this more transparent.

Re: [JBoss-user] CMP or BMP transactions, isolation level, performance
By default, JBoss has serialized access to BMP or CMP beans at runtime via pessimistic locking. There are different locking configurations that you can use that are specified in our for-pay documentation. As for JDBC isolation levels, you can only set this on a per datasource level in the *-ds.xml config file transaction-isolation. So you would define two different datasources that talk to the same DB, but define different isolation levels for both.

RE: [JBoss-user] RE: JMS problem?
Thanks Adrian. How specifically should we configure log4j on the client? We currently use log4j for logging on the client in our application and have a log4j.properties. We'll try setting the exception listener and see if we can reconnect cleanly (at a minimum detect what's happened). Obviously, the last solution would be trivial to try as well.

[JBoss-user] Help ----------ClassNotFoundException
Hi All, Greetings. I am Subramanian. S. I am facing a problem while starting the JBoss. The description is below: We are having a signed jar file call it as 'XYZ.jar'. It is an encrypted file(using some third party tool). It is having some MBeans and EJBs. It is available under an *.ear directory under server/default. Whenever we are starting up the server, We are getting a 'ClassNotFoundException' from that jar. We feel that this may due to the encryption and the default ClassLoader of jboss is unable to decrpt it. Is it so? If so, how can we specify the other classloaders to do the task. Otherwise, how can we solve this? Please help me. Thanking you in advance. Subramanian. S --- This SF.net email is sponsored by: SF.net Giveback Program.
