[Persistence, JBoss/CMP, Hibernate, Database] - cascade delete on both sides of a one-to-one relationship is
by lynchie
I have the following setup
A ----1:N---- B ------ 1:1 ----- C
I have the relationships configured so that If I delete A, it cascades to B and If I delete B it cascades to C. BUT If I also, separately delete C, it should also delete B (but not A).
However, what seems to happen is the following. Delete A, Then delete B, then delete C, then delete B again. Since B is already deleted, jboss throws a RemoveException and it all fails.
Any ideas as to how to approach this setup?

[JBoss Portal] - Re: Best way to learn
by Agathon
"thomas.heute(a)jboss.com" wrote : What you mention first looks like a weird bug in your application, not a flaw.
This may be true, but there were no indications that this was the case; otherwise, we would have fixed it. How it "looks like a weird bug in [my] application", when you:
a) Have not seen the bug
b) Have not seen the source code
c) Have no idea what environment MyFaces was running in
is beyond me.
"thomas.heute(a)jboss.com" wrote : "lack of control the developer has over the markup" is actually the best thing, as a developer i don't want to mess with markup, i want my designer to do this job. This is just a matter of components anyway and the components let the designer focus once on the way something has to be rendered.
FYI, I wear both hats: designer and developer. In formatting a user interface you have several options: CSS, the standard components (which suffer from the "flaws" I mentioned previously), and creating custom components (not fun). Among these CSS is your best bet, but it is more limited, and has more varying levels of implementation among browsers than plain old HTML (although this is slowly changing).
That said, I do agree with your point: when I put on my developer hat I just want to work with components. However, when I put on my designer hat, I want to be able to easily modify all the HTML that is produced. Balancing the requirements of developers verus those of designers is tricky business. Unfortunately, in my opinion, JSF leans too far towards the needs of developers while gimping designers.

[JBossCache] - Problems with ReplQueue and RegionBasedMarshalling
by carlabramsson
Hi all!
I'm having problems with Jboss Cache 1.4 GA (running under JBoss 4.0.4GA with JGroups 2.2.9.3).
The cache is deployed as mbean in JBoss and then it's "fetched" in a war-app. Beacuse of this we are using RegionBasedMarshalling.
The cache is also configured to use a ReplQueue and it looks like this combo is causing trouble. If I disable the ReplQueue it works just fine, and if I disable the RegionBasedMarshalling the ReplQueue works.
The error I get (when using ReplQueueMaxElements=2 and ReplQueueInterval=0) is:
| 15:42:25,814 ERROR [RpcDispatcher] exception=java.lang.IllegalArgumentException: LegacyTreeCacheMarshaller.extractFqn(): Unknown method call name: _replicate
| 15:42:25,814 ERROR [ReplicationQueue] failed replicating 2 elements in replication queue
| java.io.NotSerializableException: RpcDispatcher returned a null. This is most often caused by args for _replicate([_replicate(_put(null, /status, 10.60.15.101:4629, com.hm.website.core.cache.status.SystemStatus@10e0904, true)), _replicate(_put(null, /objects/com/hm/website/domain/navigation/NavigationNode/OBJECTS, working, com.hm.website.domain.navigation.ActionPageNavigationNode@1ba67ec, true))]) not being serializable.

| 16:06:56,886 ERROR [ReplicationQueue] failed replicating 0 elements in replication queue

|
So, is there a known issue with this combo?
I tried debugging the cache (callRemoteMethods(List mbrs, MethodCall method_call, int mode, boolean exclude_self, long timeout) in TreeCache.java) and it seems like the problem is with the LegacyTreeCacheMarshaller. Should it even be used?
Thanks for any help!
BR, Carl
Here is my init-block in the war-app that connects to the cache in JBoss:
|
| ObjectName objectName;
| try {
| objectName = new ObjectName(CACHE_MBEAN_OBJECT_NAME);
| }
| catch (Throwable t) {
| throw new NetCacheException("Malformed TreeCache ObjectName");
| }
|
| TreeCacheMBean mbean;
| try {
| mbean = (TreeCacheMBean) MBeanProxyExt.create(TreeCacheMBean.class, objectName);
| }
| catch (Throwable t) {
| log.error("Unable to locate TreeCache MBean under object name " + CACHE_MBEAN_OBJECT_NAME, t);
| throw new NetCacheException("Unable to locate TreeCache MBean under object name " + CACHE_MBEAN_OBJECT_NAME);
| }
|
| cache = mbean;
| log.info("Successfully retrived TreeCache mbean from JBossAS");
| try {
| cache.registerClassLoader("/", Thread.currentThread().getContextClassLoader());
| } catch (RegionNameConflictException e) {
| log.error("Could not register classloader!", e);
| throw new NetCacheException("Could not register classloader!", e);
| }
| try {
| cache.activateRegion("/");
| } catch (RegionNameConflictException e) {
| log.error("Could not activateRegion / ", e);
| throw new NetCacheException("Could not activateRegion / ", e);
| } catch (CacheException e) {
| log.error("Could not activateRegion / ", e);
| throw new NetCacheException("Could not activateRegion / ", e);
