Clustering EJB3 Tutorial Not Working

[aho]

I have installed in my Win XP PC with jboss-4.0.3RC1-installer.jar with selection deploy type ejb3. My testing with most ejb3 (without @Clustered annotation) works fine. I tried to test clustering using the example in the tutorial download from JBoss site and follow the steps accordingly. On performing ant run.stateless and an run.stateful , the below error messages appeared in the console. I check the deploy folder (all) which has the following:
ejb3-deployer
ejb3-clustered-sfsbcache-service.xml
ejb3-entity-cache-service.xml
ejb3-interceptors-aop.xml

I noticed that cluster-service.xml was missing and I copied one over. I copied the jbossha.jar to all/deploy/lib as well but all these did not solve the problem. Are there anybody who has successfully tested the Clustering EJB3 tutorial example??

Hi,

I think your problem its the Jboss you installed, the jar installer only comes with the default configuration, and clustering needs an all conf.

I did the following:

- Downloaded the non-jar file for Windows
- Extracted the contents
- Downloaded the last EJB3 distribution, and applied them into my Jboss directory with the instructions in readme.txt (except the aop directory, because the names are different)
- Compiled the clustering example from tutorial.
- My clustering ejb works fine without errors, the only problem its that I haven´t able to see the load balancing or the failover working, the calls are always handled by a single jboss, and they never reach the other server, and if I shutdown my server, the calls never gets redirected to the other server, instead my client gets an error

Does anyone knows how to make load balancing and fail over works ...

this is my jndi.properties

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=dev-diegop:1100,dev-franciscor:1100

Using the JBoss installation procedure you recommended works for the clustering example. When I tried the other example, such as stateful session beans, the following errors appeared in the console. Seems like there is no one installation that works for all implementation yet.

I am not able to fing the Clustering tutorial of EJB3 in Jboss site . Please anybody give the URL?

[vincegay]

I believe it is
