[Beginners Corner] - Re: MDB Not working

by harini533

Hi, I am trying to do something similar. I want to invoke start and stop delivery on the MBean from a script. The method MBeanServerLocator.locateJBoss() works fine only from within the Jboss container and not from the command line script. I am unable to figure out how to get a handle to the MBean server. What should I pass as servername to load the MBeanServer in the below code? Object lServer = initialContext.lookup(serverName); I tried to give the machine name as the servername, but it does not seem to work. Any help would be appreciated. Thanks, Harini View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4085031#4085031 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4085031

All 4500 nodes in region X would be evicted as per eviction defined in region X and all 1000 nodes in region _default_ would be evicted by the eviction time defined in region _default_. | This is wrong. A region is just a subtree. So if you have a region defined as /a/b/c, anything you put under /a/b/c is counted towards the number of nodes in the region (e.g., /a/b/c/d or /a/b/c/e or even /a/b/c/d/e/f/g). If you have > MaxNodes nodes in the region, they will still exist in the DB, just not in memory. Your ideas around eviction are all wrong as well. Only nodes exceeding MaxNodes are evicted.

If a node has children it just empties all the data in the node, marks it as uninitialized, but keeps the node as it has a structural role to play.

[JBoss AOP] - Re: jboss aop

by marimuthub

Hi, Sorry to ask further question. I find a method call registerClassLoader in AspectManager class. Can it be possible to resolve the issue using register class loader or re loading class loader.

[JBoss Seam] - Batch removing, conversations and transactions managment

by v.masterov＠gmail.com

I have a question concerning batch entity deletion. I need to delete multiple entities at once, while some of them have references to other entities. When I try to delete a group of entities without any references, the operation is successful. But if at least one of the entities in the batch has references, the transaction is rolled back entirely. What I am trying to do is to delete all the entities without references, while the others (entites in the batch with references) can be left unchanged. I am trying to delete entities using separate transactions for each entity, but still fail. JBoss Seam tutorial mentions manual transaction management through conversation management (using the annotations @Begin(flushMode = FlushModeType.MANUAL) and @End). I am trying to perform deletion using the two beans. The first bean implies cycle iteration with all ids and EntityManager is not injected into this bean. A separate deletion is performed within the second bean, this one injects EntityManager. It is not clear how to manage conversations. Both beans are conversation beans. After the first iteration the first bean is performed in the conversation context declared in the second bean, i.e. "join = true". If I declare "join = false" the first iteration returns exception:"java.lang.IllegalStateException: begin method invoked from a long running conversation, try using @Begin(join=true) on method: remove". With "join = true" each next iteration is performed within the same conversation, and as far as I understand in the same transaction. This results in entire rollback of all deletion operations. Please, help me !!!

[JBoss AOP] - Re: jboss aop

by kabir.khan＠jboss.com

As Flavia said, if you are using loadtime weaving you need to "prepare" the joinpoints. This information must be available when the class is first loaded. Once the class is loaded we cannot modify the class. Meaning you cannot introduce more hooks for AOP once the class is loaded, but we can modify what aspects are applied to those hooks. A "prepare" is basically the same as an empty "bind".
