How to correctly access clustered web services?

[fdagostini]

Hi,

I'm able to deploy some Ejb's on my cluster and use them from a Swing app, all I do is connect

to the ha-jndi port and use them through context, lookup, etc. This way I can automatically

use any node of the cluster if I just put some of them (IP) on jndi properties. It works

perfectly fine, balancing the load with RoundRobin.

My question:

I'd like to have a similar approach using web services so I could use any node to connect,

automatically switching on fail, just like happens with the ejb approach. Still using the

Swing app as a client, needing to decouple and make the same services available to

.Net (here comes jbossws).

Details:

My ejbs are simple, think of the famous "multiply number example".

My web service would provide the same functionality.

I tried already using Tomcat with mod_jk to balance the load but it's a way I'm not

happy with (I don't want to centralize, Ejbs with ha-jndi work so beautifully)

I've read something about UDDI and ESB but I still don't know if any fits my problem,

or if they too much for a little problem.

Using JBoss 5.1.0.

If someone could me just point me in the right direction telling me wich method to

google for I'd appreciate. Thank you.

ps: if something above is confusing, pardon my English

In contrast with RMI calls the HTTP access is not automaticaly clustered/load balanced.

A common solution for this is a hard- or software loadbalancer to ensure this.

We use apache with mod_jk.

Thanks Wolf, that works ok with servlets and http requests in general.

For those who also need to deploy web services in a clustered environment

look for ESB. They can route, fail over, balance, convert and etc web services.

I still don´t know how to setup an ESB but I think this is the way.

Cheers.
