[JBoss Seam] - Re: Getting LazyInitializationErrors with a SMPC
by norman.richards＠jboss.com
I'm not a persistence expert - so you'll probably want to ask Gavin when he gets back. In general I try to be careful about session-level data. Sessions generally live a long time, and session data can easily go stale. (a search result, or something) You'll often find that the best strategy is to reload the data from the database on each request to make sure you have uptodate objects. You take the object into a conversation for the purpose of some sort of multi-screen editing transaction.
So, what you might consider doing for the customer is to store the id in the session and use a seam wrapper object to retrieve actual customer as needed. You won't have to worry about a LIE because your object won't detach from the PC until the end of the request. And, you'll always have the most current data. If you are worried about efficiency, you can configure your second level cache to deal with reads.
But, as I said, I'm no persistence guru.

[Persistence, JBoss/CMP, Hibernate, Database] - OutOfMemoryError: Java heap space during 2nd execution
by ameisinger
Hi JBoss-Community!
I am using JBoss AS (4.0.4 GA) with Hibernate 3.2.0CR2. While fetching a big amount of data (1 Table with 58 columns and 1000 rows) a 2nd time I got a java.lang.OutOfMemoryError: Java heap space.
The mysterious thing is that the query works properly at the first time but at the second time I get the same exception mentioned above.
I use the JBoss AS inside of eclipse (vmargs -Xms1280m -Xmx1280m).

[Beginners Corner] - Looking up a @Stateful Bean fails cause of AOP Interceptor (
by cwulf
Got a ClassLoader-Problem with EJB 3's Stateful Session Bean's i don't unterstand.
Have got included all required Client-JAR's (incl. jboss-aop-jdk50-client.jar).
Stateless Session Bean's are working fine, but if i look up for a Stateful i am getting a problem with a ClassLoader, can't find org.jboss.aop.advice.Interceptor.

Don't know if this is a client or server side problem, because the class is definitly in the client's classpath (if i drop jboss-aop-jdk50-client.jar the Stateless stop working cause of the Interceptor class).
Any ideas?
