[jboss-user] [Clustering/JBoss] - Very strange problem while looking up HAJMS Topic
JBoss 4.2.3, deploying the topic as a HASingleton.
An SLSB deployed on all nodes uses the Topic.
Let's say that JMS topics run on node A, and i'm calling the EJB method on node B
(everything works fine when calling it on node A).
Since injection fails (in a surprising way too: getting a NamingContext instead of a
Topic...), I have tried looking up the Topic at two different timings:
1/ Manual lookup in @PostConstruct
2/ Very same manual lookup before method invocation (for instance with an Interceptor)
Result:
1: fails (NameNotFound)
2: works (except i have a Throwable.STACKTRACE message about closing my connections
myself)
What the hell, how is it possible?
My lookup:
| private void initTopics() throws NamingException
| {
| log.info ( "____________initTopics/START______________" );
| InitialContext ctx = ddgetfInitialContext ();
|
| Object ref = ctx.lookup ( "topic/DepuisEmbarqueTopic" );
| log.info ( " ref 1: " + depuisEmbarqueTopic );
| depuisEmbarqueTopic = (Topic) PortableRemoteObject.narrow( ref, Topic.class );
| log.info ( " depuisEmbarqueTopic: " + depuisEmbarqueTopic );
| }
|
| private InitialContext ddgetfInitialContext () throws NamingException
| {
| Properties p = new Properties();
|
p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory"); p.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
| p.put(Context.PROVIDER_URL, "[hidden ip1]:1100,[hidden ip2]:1100");
| p.put("jnp.partitionName", "PartitionNavineo");
| p.put("jnp.discoveryGroup", "230.0.0.4");
| p.put("jnp.discoveryPort", "1102");
| p.put("jnp.discoveryTTL", "16");
| return new InitialContext(p);
| }
|
Something I haven't mentioned yet, since I was afraid to drown you in information
(might be important or not):
This only happens if JMS has moved back and forth between the 2 nodes. The sequence of
successive topologies (where 1 and 2 are the nodes, and i bold the JMS MasterNode), which
i note in roman numbers:
I: { 1 }
II: { 1 , 2 }
III: { 2 }
IV: { 1 , 2}
The problem manifests itself at IV.
