Unique JNDI for multiple clustered servers and EJBs

fchaves Oct 25, 2012 2:27 PM

Hi all,

I want the following deployment and sfsb calls:

Server A (Cluster member)

|- Deployments

|-- sfsb1

|-- sfsb2

Server B (Cluster member)

|- Deployments

|-- sfsb3

|-- sfsb4

|-- sfsb5

Server C (Cluster member)

|- Deployments

|-- sfsb6

It is possible to invoke EJBs from any clustered server's ejb pointing to a unique JNDI URL located on any cluster server? I mean, for example, if I want to invoke sfsb1 from sfsb6, I want to do that looking up to a centralized JNDI Registry in Server A, server B or any cluster member server without "wire" connections between all servers.

This is because at runtime, i want be able to change EJB deployments and I want to have just one JNDI provider URL for all servers.

There is any way to reach that operation schema?

Thanks,

Francisco.

Are all server in the same cluster? Are sfsb# the same bean or each different?

I think you will need the EJBCLIENT-34 feature which is not integrated for use inside a server acting as client.

I Wolf-Dieter,

Answers:
"Are all server in the same cluster? Are sfsb# the same bean or each different?"
R/All the servers are on registered to same cluster.
sfsb# are different EJBs.

"I think you will need the EJBCLIENT-34 feature which is not integrated for use inside a server acting as client."
R/Is EJBCLIENT-34 included in JBoss AS 7.1.2 Nightly Build of 25-Oct-2012??
How can I use EJBCLIENT-34 for invoke remote EJB from another EJB on diferent JBosss AS Server?

Thanks a lot.

EJBCLIENT-34 is not integrated neither in 7.1.x nor in 7.2 (upstream) at the moment. I can't give a date to you when it is supposed to.

ATM there is no way to do that without 'wire' the connections. If the EJB is unique as in your case you are able to call each as you want (with wired configuration), see documentation here

Hi all,
I wonder if anything has changed since Oct 28 2012 in this topic? Maybe recently released Wildfly 8.1 has improved this in some way?
I still have to 'wire' connections as described in documentation?
Is it possible to do it using only the app server cluster and some JNDI configuration?

Wolf-Dieter Fink: do you have some thoughts about it?

Thanks,
Piotr

There are some options, i.e. there is a scoped-context implementation. But it depend on your use-case whether it is possible or not.
If you have special questions you might open a new thread and provide informations
