SourceForge User closed JBAS-219:
---------------------------------
Resolution: Rejected
> Out-of-memory Exception
> -----------------------
>
> Key: JBAS-219
> URL: http://jira.jboss.com/jira/browse/JBAS-219
> Project: JBoss Application Server
> Type: Bug
> Reporter: SourceForge User
> Assignee: Scott M Stark
>
>
> SourceForge Submitter: jsimone .
> OS: WinXP Pro
> JDK ver: 1.3.1_04-b02
> This occurs in Both 3.0.0 final and 3.0.1RC1. Each
> iteration creates 10 CMP 2.0 entity beans and returns.
> So we get the memory exception after creating about
> 14,510 entities.
> Below is the relevant client code and its result:
> int totalPasses = 10000;
> for (int pass=1; pass <= totalPasses; pass++) {
> // Create a bunch of sample data using the event
> manager interface ...
> messageBox("CREATE SAMPLE
> EVENTS", "Pass "+pass+" of "+totalPasses, " ");
> eventIds = eventManager.createSampleEvents(10);
> }

> The session facade has "RequiresNew" as the
> transaction attribute and each of the entity bean
> methods has "Required".
> My expectation is that when the client invokes:
> eventIds = eventManager.createSampleEvents(10);
> that the createSampleEvents method of the
> eventManager Session bean WILL create a new
> transaction. Then, that 10 entity beans will be created
> under that transaction. Finally, when the
> createSampleEvents method returns to the client the
> transaction will be complete and a commit will be
> performed for the 10 enities created.
> I don't see any evidence of this happening.
> Shouldn't I be seeing SQL COMMITS in the server.log?
