[Persistence, JBoss/CMP, Hibernate, Database] - Entity inheritance and referencing other entities with casca

by filip.hrbek

Hi, I cannot figure out how to handle references to other entities in subclasses in the inheritance hierarchy. Let's consider following example (a bit incomplete to make it easily readable): @Entity | @Inheritance(strategy = InheritanceType.JOINED) | public abstract class Man { | ... | public Long getId(); | | public String getName(); | ... | } | | @Entity | @OnDelete(action=OnDeleteAction.CASCADE) | public class Employee extends Man { | ... | @ManyToOne | @OnDelete(action=OnDeleteAction.CASCADE) | public Department getDepartment(); | ... | } | | @Entity | public class Department { | ... | public Long getId(); | public String getDepartmentName(); | ... | } | Data: Man(id=1, name="John Black") Employee(id=1, department_id=0) Department(id=0, "Production") Notice the cascading deletes. As soon as the department is deleted, also the employee is deleted - but as the InheritanceType.JOINED is used, only a part of the employee is actually deleted. The abstract part of the employee (in the "Man" table) remains in the database (which is bad!). Any attempt to instantiate the man named "John Black" fails on the "Cannot instantiate abstract class or interface" exception" (no surprise, is it?). I wonder if there is any way how to delete also the abstract part of the record automatically if the extending part of the record is deleted. Thanks for hints.

If you give me instructions on how to replicate, I'll take a look. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4100745#4100745 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4100745

[JBossCache] - Re: Migrating to 2.0.0 using PropertyConfigurator

by manik.surtani＠jboss.com

Hmm. From 2.1.0.GA onwards, I can overload ConfigurationFactory.createCache(String, boolean) with createCache(InputStream, boolean) and createCache(URL, boolean). But for 2.0.0, you'd have to spin this by hand, unfortunately, doing something like the following: 1. Subclass org.jboss.cache.factories.XmlConfigurationParser and add a method to parse a URL. 2. In your method, call (protected) method XmlConfigurationParser.parseStream(InputStream is) 3. ... and get a hold of a Configuration object which you can then pass in to the ConfigurationFactory.

[JBoss Seam] - Re: faces-config is necesary? Im lost

by pete.muir＠jboss.org

We declare the facelets view handler in web.xml in booking - this is a throwback to when Ajax4jsf required it declared there.

[JBoss Seam] - Re: h:selectOneMenu performance - any suggestions?

by pete.muir＠jboss.org

But I can see that it would be useful to be able to cache the created dropdown list (in it's generated form). Create a JIRA issue, I'll see what I can do.

[JBoss Messaging] - undelivered message on clustered queue with consumers

by schmod54

Hi, I have jboss messaging 1.4.0 running in a jboss 4.2.1 cluster with 2 nodes. I have a clustered queue. Each node in the cluster has 2 consumers listening on this queue. Everything works fine, except occasionally a couple messages get stuck. These messages sit in the queue even if there are no other messages anywhere else in the cluster and all of the consumers are idle. Most messages received after the stuck messages get processed normally, unless they also get stuck. The only way to get them consumed is if I remove consumers from the node where they are stuck, and add new consumers. Anyone else seen this type of behavior or know the cause? I checked the JIRA briefly and didn't see anything obvious. Thanks!

[Messaging, JMS & JBossMQ] - Managed connection factory just for pooling?

by odoepner

Hello, I am trying to use JMS with a managed ConnectionFactory. I have implemented a Utility bean similar to http://wiki.jboss.org/wiki/Wiki.jsp?page=JmsSenderBean with a resource-ref to "java:/JmsXA". According to our lead architect we don't really need / want to include JMS into XA transactions but we want to take advantage of the connection pooling. Is it possible to configure the connection factory that way? thanks Oliver View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4100739#4100739 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4100739

s:cache is really useful for output only components.
