I think the best approach is just hack 2 or 3 queries together ad hoc and get them in the web console, just to get a feel of the web console in general. No reusability in mind. Consider this a prototype. Then we should design the BAM DB (shouldn't we call this a Business Intelligence DB instead ?) and build the generic query framework on top of that. For the design of the BAM DB, i want to work this out in the jbpm 4 prototyping module: lightning. Once you're ready i can help you on your way in there. Thoughts ?

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: JBMESSAGING-519 - Failover(HA) design discussion

by timfox

What are these ID's you are referring too? Can't you just create a new producer? Or maybe I am misunderstanding what you are doing?

[Javassist development Forum] - add a new annotation problem

by coral

Hi all, I am working on ejb3 project. Ejb3 always use some annotations such as "@Stateless","@Remote", "@RemoteBinding" and etc. Now I want to use javassist to generate these annotations. But have some problem. Can you help me to point out my mistake? <The class I wanna modify> | @Stateless | public class StatelessTest { | public String sayHello(String user) { | return "Hello" + user; | } | | } | <In this test case, I wanna put a new annotation "@RemoteBinding(jndiBinding = "StatelessTest /remote")" into StatelessTest class> | public class AnnotationTest extends TestCase { | public void testAnnotation() { | ClassPool pool = ClassPool.getDefault(); | pool.insertClassPath | ("D:/workspaces/.maven/repository/jboss/jars/jboss-annotations-ejb3-4.0.3.jar"); | CtClass c = pool.get | ("com.quartet.fwk.container.hivemind.qar.models.StatelessModel"); | ConstPool consts = c.getClassFile().getConstPool(); | ByteArrayOutputStream output = new ByteArrayOutputStream(); | AnnotationsWriter writer = new AnnotationsWriter(output, consts); | writer.numAnnotations(1); | writer.annotation("RemoteBinding", 1); | writer.memberValuePair("RemoteBinding"); | writer.constValueIndex("remote"); | writer.close(); | byte[] attribute_info = output.toByteArray(); | AnnotationsAttribute attribute=new AnnotationsAttribute(consts, | AnnotationsAttribute.invisibleTag, attribute_info); | c.getClassFile().addAttribute(attribute); | Object[] objs = c.getAnnotations(); | System.out.println(objs[1]); | I think these codes should work very well, but it throws exception: java.lang.reflect.InvocationTargetException detailMessage="bad descriptor: RemoteBinding"; thank for any replay!!

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: JBMESSAGING-519 - Failover(HA) design discussion

by clebert.suconic＠jboss.com

Could fix the MessageProducer under transaction environment. Now I have a testcase sending messages in a transacted session, right before calling commit I called failOver, and all the messages were received on the new node. Basically I created a method called transferHAState under DelegateSupport what will set the ID (copying it from the new server's object). That is allowing handleFailoever on ConnectionAspect to reconnect objects to the new server and change IDs to the expected IDs on the new server. It's working nicely now.

[Design of Clustering on JBoss (Clusters/JBoss)] - Use jboss.partition.udpGroup in NamingContext

by bstansberry＠jboss.com

Right now NamingContext defaults to 230.0.04 for the multicast address to use for auto discovery. The server defaults to ${jboss.partition.udpGroup:230.0.0.4}. This is a bit of a mismatch. It leads to breakage in the testsuite if the -u switch is used on the server, since tests typically don't manually set the jnp.discoveryGroup property. We could of course change the tests to set jnp.discoveryGroup, but that will be prone to breaking. It's tempting to have NamingContext check the system property before defaulting to 230.0.04. A further temptation is to use StringPropertyReplacer in NamingContext for any property, and thus allow controlling the JNDI config from the command line. This would add a dependency on jboss-common.jar though; don't know if there are any cases where NamingContext is used where jboss-common.jar isn't required anyway.

by clebert.suconic＠jboss.com

Never mind: Answering my own question: TxState has the list of previously sent messages associated with the current transaction. I will have to resend then if a failOver event happened.

[Design of JBoss Web Services] - ws-eventing: event notification failure

by maeste

I noticed that event notification failure are completely lost. If an event notification fail jbossws just log the error and does nothing. I took a look and I think could be pretty simple to modify the code to store these failures in the SubscriptionManager MBEAN with exceptions generated to make possible to analyze problems without watching console all day long :) And is also possible add one or more methods to the MBEAN to resend failed notification. What do you think about? Can I put my hand on this part of code?
