The identical EAR works fine (loads and runs) in 4.0.5 and in 4.2.1. I also see the same error coming out of a fundamentally identical PostgreSQL DS file. Did something change in 4.2.2 regarding no-tx-datasources?

[jboss-user] [Installation, Configuration & Deployment] - Reading Runtime Property Files from EAR
Hello, I'm trying to introduce runtime properties to my EAR-based application. Ideally I would read in a default properties file, and then an an overrides properties file into a java.util.Properties object to be queried by my application at runtime. Is there a standard way of doing this? The closet thing I've seen is the properties-service.xml mbean, but that looks like it is meant for VM specific properties, not application-specific properties. I've also tried loading the file as a module in my application.xml file but I get an "incomplete deployment" error on startup, even when specifying the alt-dd element. Any suggestions?

[jboss-user] [EJB 3.0] - Re: Entity relationship and remove operations
I'm facing a similar problem with child entities not being deleted with their parents. The exception I see is "javax.persistence.EntityNotFoundException: deleted entity passed to persist", and it looks like the entity manager is trying to persist the child entities with null references to the parent. I have CascadeType.ALL set on that relationship. I'd be very disappointed to learn that manual deletion of child entities or database-level cascades were necessary, as the whole point of the JPA cascade functionality is to avoid that. But, I don't have a better answer yet. (BTW, I'm also on jboss 4.0.5 and postgres 8.1; it's bizarre that you're hitting a constraint violation and I'm not even getting that far).

[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - SessionException: session closed after very large native que
Hi All, I've got a PostgreSQL 8.1 database that I'm performing a series of large queries on under JBoss 4.0.5, and the EntityManager is closing after each query such that the next fails. The queries are native SQL, and return in excess of 250,000 rows. The datasource is defined as non-transactional to avoid transaction timeouts: | | MyDB | jdbc:postgresql://localhost:5432/MyDB | org.postgresql.Driver | ... | ... | | And a suspect persistence unit: | | org.hibernate.ejb.HibernatePersistence | java:/MyDB | | | | | | The thing that's suspect here is the jta-data-source element, when I need this datasource not to be transactional, and I should be using non-jta-data-source. Unfortunately, there's a bug that prevents me from doing that (http://jira.jboss.com/jira/browse/EJBTHREE-433) The EntityManager is injected by JBoss using PersistenceContext, and what I find is that the first query to run will succeed, and get through all of the expected data, but the next query to run will generate a SessionException because the EntityManager is getting shutdown somewhere. So, has anyone else encountered this kind of behavior? Is it likely due to the jta-data-source declaration? Thanks.

Hey Gommo, how's it going? I'm able to do a JNDI lookup for the datasource
using the value of the tag. So, I belive this would work for
you:
| InitialContext ctx = new InitialContext();
| Object ds = ctx.lookup("java:/PostgresDS");
|
I'm not clear on why in the datasource config there's no leading "java:/",
maybe somebody more knowledgeable about JNDI can explain that.

[jboss-user] [EJB/JBoss] - Re: Unit Testing Practices
Hi Gommo and Tarantula, I'm glad you guys got something working with Embedded JBoss. I guess I'll take a another stab at that approach. How are you bundling and running the tests with your application? In other words, where does Embedded JBoss live compared to the real server, and how do your unit tests find it? Ideally, I'd have Embedded JBoss bundled in with my application so developers could check the whole project out of source control and be able to run the tests, but with 20+ jars that seems unwieldy. Also, are you running the TestNG units from Eclipse? I was unable to load configuration files for the embedded server while running JUnits from Eclipse, so if you have any suggestions there I'd appreciate it. Thanks!

Hi Syed, You should say what version of JBossIDE you're using since there were some pretty big changes from 1.5/1.6 to 2, but here's a guess anyway ... I believe you need to create the server first, since JBossIDE doesn't know where JBoss is installed in all cases and so can't configure it automatically. Try going to Window->Preferences->Server->Installed Runtime and setting up a new JBoss 4 server. Hopefully JBossIDE will pick up on its existence.

Eclipse 3.2.1 JBoss IDE 2.0 beta2 plugin Sun Java 1.5.0_08 (64 bit) Debian I've been seeing tremendous instability in Eclipse ever since migrating from JBossIDE 1.6 to the 2.0 beta. In particular, operations like hibernate code generation and reverse engineering routinely result in crashes. Controlling the JBoss server is enough to do it though. Often there's an out of memory dialog that pops up, mostly it just freezes entirely and I have to kill -9 the process. I've tried bumping up the memory but even with 3/4 Gig of memory it happens. My co-oworker with the same setup on 32 bit Java on OSX sees the same behavior, so it's not the underlying VM implementation that's responsible. And doing non-JBossy things I can keep the Eclipse session going far longer. Anybody else seeing these sorts of problems? I've resorted to opening the necessary files for a given task and then intentionally shutting down Eclipse so that my workbench will be in proper shape after the inevitable crash :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3994850#3994850 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3994850 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Thanks for the suggestions. But, are these actually capable of testing EJB3s? MockEJB hasn't been updated in two years and I'm doesn't look like it supports dependency injection. JUnitEE is also two years out of date and doesn't work with either JUnit 3.8 or 4.1, and doesn't say what versions it is compatible with. Cactus also seems behind the curve, supporting only J2EE 1.3, and mentioning only EJB2. And it's massively overkill for my testing needs. Hopefully I'm just being dense today, but at this point it's looking like I need to roll my own in-container test runner as a servlet or Service bean.
