Clustering and Loadbalancing with HTTP and EJB
by Reinhard Brandstaedter
Hi,
I'm currently in the planning stage of a clustered JBoss Environment.
I understand that there are two service architectures for clustering and
loadbalancing. One with a client-side interceptor used for fat-clients
that communicate via ejb/rmi and a loadbalancer for HTTP access via
Apache and mod_jk.
If i need a mixed setup of both (web-access and rich-client
applications), how would someone distribute the load over multiple
cluster nodes with the following aspects:
a.) the fat-clients should have a higher priority. For example if
massive webclients cause a high load on the cluster the fat-clients
should not be influenced by this
b.) both client access (web and fat) should be distributed over all
nodes in the cluster to improve failover.
I thought of the following setup:
- 4 JBoss Nodes in the cluster partition
(identical ressources/performance)
- 4 mod_jk connectors with different loadbalancing factors 2/2/1/1
- fat-client interceptor with loadbalancing factor 1/1/2/2
This would ensure that all nodes are utilized (for failover) and the
web-clients can't influence the fat-clients that much, right?
The main part of the web-clients would go to node 1 and 2 and only in
case of a fail utilize 3 and 4 more (maybe even use higher lbfactors
than 2).
That's the theory :-). Some Questions:
- I intend to use round-robin for loadbalancing (both clients). How can
I specify loadbalancing factors for the fat-client interceptor? I only
found a documentation how to do it with mod_jk
- The fat-client has to download a proxy class from a cluster node. How
is this done initially? How does the client select the node? Is this a
static definition? If yes? what happens if this node is down, or does
the client need a (maintained) list of nodes (before even downloading
the proxy class) as the mod_jk loadbalancer does?
Thanks for answers!

[JBoss AOP] - Get bean context from an Aspect
by Giordacchio++
Hi,
I'm trying to get the context of a bean that I'm intercepting using an AOP aspect.
I've tried to use InitialContext(); and lookup(......) but it doesn't work and it seems to be impossible to get the context of a bean inside the .jar archive from my aspect.
The new InitialContext works fine, the lookup also works and it give to me a reference to the desired bean but I'm not able to call method on this bean !!
I get the following execption:

I've tried the same thing on the booking example and I got the same errors !
There is a method that I can call in my interceptor similar to getTargetObject() that instead returning a reference to the target object (a bean in this case) returns his context ???
Something like a getBeanContext() ???
Thx ;-)
