basic clustering deployment
Looking for some insight as to what TOMEE-334 is meant to imply.

Hi,
Currently we mainly rely on tomcat for it.
Only the deployment is enhanced but not sure it is justified for you (think
you already have better solution for it)
Personnaly i activate tomcat clustering then add our provisioning module to
finally deploy fron nexus (mvn:groupid:artifactid:version:war)
But tomcat clustering is for small clusters so not sure it matches your
need.

Hi guys,
I'm working on Tomee clustering support on Amazon. Looks like you already
have something in place on trunk. Can you share what's the plan?
Currently, one my engineers is setting it up this way:
On ubuntu EC2 use cloud init feature to run a script when an instance is
created.
Grab Tomee dir from EBS
Deploy WAR to Tomee from EBS/S3
Start Tomee
Amazon load balancer will take care of balancing requests among instances as
needed based on load.
Am I on the right track? Is there any documentation of clustering support in
Tomee? Session replications, etc..

well here are the classes used:
http://svn.apache.org/repos/asf/openejb/trunk/openejb/tomee/tomee-catalina/src/main/java/org/apache/tomee/catalina/cluster/
first we have an observer which is notified when an app is deployed:
http://svn.apache.org/repos/asf/openejb/trunk/openejb/tomee/tomee-catalina/src/main/java/org/apache/tomee/catalina/cluster/ClusterObserver.java
then we send a deploy messge (
http://svn.apache.org/repos/asf/openejb/trunk/openejb/tomee/tomee-catalina/src/main/java/org/apache/tomee/catalina/cluster/DeployMessage.java
)
we have the property (to be configured on all middles)
"tomee.cluster.deploy.send-archive"
to know if we serialize the archive or if we use file system to share the
archive
then our tomee has a cluster listener (
http://svn.apache.org/repos/asf/openejb/trunk/openejb/tomee/tomee-catalina/src/main/java/org/apache/tomee/catalina/cluster/TomEEClusterListener.java)
which simply call our deployer to do the work. The trick here is to
deploy+propagate the deployment only if the app is not already deployed
same idea for the undeployment excepted we just need th path to undeploy (=
all installations are the same for the moment or use the same file system)

Still catching up after JavaOne and crazy travel. If you can write even two paragraphs on it and post it to the list that would be great.

No, I mean how does it work how was it implemented? Usually for large features we try to have some discussion.

Hi David,
ability to deploy on a cluster with a single deployment
