I have a component done in JSF 1.x, this component has a command button as follows <h:commandButton ... action="#{templateController.next}" /> Where templateController was passed as an EL binding and can be any object that implements a certain interface.

I'm using glassfish 2.1 and 2.1.1. If I've a bean method annotated by @TransactionAttribute(value = TransactionAttributeType.REQUIRES_NEW). After doing some JPA stuff the commit fails in the afterCompletion-Phase of JTS. GlassFish logs this failure only. And the caller of this bean method has no chance to know something goes wrong. So...
I print a list directly in the servlet using the print writer and the list prints. When I try to put in the jsp however the list doesn't print whether I use JSTL or scriptlets. I tried to test in JSTL and scriptlet if the object is null and turns out that it is! Why does this happen and how can I fix this? Servlet code that works ...
I've the same problem as described here In the generated SQL Informix expects catalog:schema.table but what's actually generated is catalog.schema.table which leads to a syntax error. Setting: hibernate.default_catalog= hibernate.default_schema= had no effect. I even removed schema and catalog from the table annotation, this caus...
How do I set the global transaction isolation level for a postgres data source. I'm running on jboss and I'm using hibernate to connect. I know that I can set the isolation level from hibernate, does this work for Postgres? This would be by setting the hibernate.connection.isolation hibernate property to 1,2,4,8 - the various values o...

I have 2 ejbs. Ejb-A that calls Ejb-B. They are not in the same Ear. For portability Ejb-B may or may not exist on the same server. (There is an external property file that has the provider URLs of Ejb-B. I have no control over this.) Example Code: in Ejb-A EjbBDelegate delegateB = EjbBDelegateHelper.getRemoteDelegate(); // lookup f...
When I'm using @EJB annotation to access stateless EJB through remote interface in common HttpServlet, it works OK: public class ListMsgs extends HttpServlet { @EJB private Msgs msgsRI; ... protected void processRequest(...) ... { List msgs = msgsRI.getAll(); ... } ... } But when I'm trying the same thing in Wick...
I'm trying to do some validation of complex constraints on Hibernate entities in a JBoss JEE system. For that purpose, I need my validator (whether it be an actual JSR303 validator or just an EntityListener for PrePersist/PreUpdate/PreRemove) to have access to my DAO beans. Much perusal of JSR303 stuff doesn't give me any indication that...
The project has an EJB module & a web module. Changing the server is easy, but I'd like to switch to EJB 3.1 also but I believe I need to change all kind of configuration files since I can't do it from the project properties window(s). Any tips or links do useful documentation will be greatly appreciated. Thank you! ...

Do I package a stateless session bean in a war file or a ear file for deployment? ...
I have created an EAR with a web project, ejb3 project and the ejb client. I'm able to call the bean methods via injection in the servlet. I'm planning to use a ServiceDelegate which is a pojo to handle the bean invocation. So I'll call the delegate from my servlet and the delegate will call the appropriate beans and its methods. But I'...
Java EE 5 / EJB 3 / JSF 1.2, using Facelets / ICEfaces 1.8.2 I'm authenticating my users with JAAS, but I think that simple role-based authorization is insufficient for my needs—my users' permissions need to be computed out of data in JPA entities. I'd like to add to certain pages a check that gets some entities from an EJB, does a litt...
