Hi
you can give o.a.c.cluster.session.SimpleTcpReplicationManager a
chance, but I don't know it works really.

Hi Filip,
I understand that I will just change the session in a way the delta
manager will replicate everything.
But is there no other Manager I can use which just replicates the
complete session and not just the changed data (like the
DeltaManager does)?!
I couldn't find a Manager which replicates everything. Is there one?
Thanks in advance!
Andy

even with this method, you are not managing the sessions, you're
just making sure that everything gets replicated, so doing this,
you are not changing the session manager.
remember, the code below would be inserted into a filter or a valve

Hi Filip,
Thanks for your answer. I also thought about this solution of just
setting all objects again at the end of the doGet method.
But if possible I would like to use a tomcat replication mechanism
since I do not want to "manage" session since I have a tomcat-
built-in
session manager :)

to achieve what you want, although slower, you can create a filter,
and in that filter simply set all the attributes again
Enumeration e = session.getAttributeNames(); while ( e.hasNext() ) {
String name = e.next();
Object value = session.getAttribute(name);
if ( value != null ) session.setAttribute(name,value); }
you get the point :)

Hi everybody,
I have a Tomcat 5.5 cluster with 2 nodes on SLES8 and want to
replicate the complete session before the response is send.
According to the Tomcat Clustering documentation the example with
the DeltaManager does this since the ReplicationValve triggers
the replication after the request has been processed and before
the response is sent.
Unfortunately the DeltaManager only replicates the changed data.
Only changes made by using methods like setAttribute make changes
visible to the DeltaManager and changes made to the object (like
changing one field value noch setAttribute-call) do not.
Thus I would need to change the way these objects are handled in
the application. So I thought it would be the easiest way to just
replicate the complete session instead of changes only. Is this
possible?
JavaDoc of org.apache.catalina.session.StandardManager:
"Standard implementation of the Manager interface that provides
simple session persistence across restarts of this component
(such as when the entire server is shut down and restarted, or
when a particular web application is reloaded."
This sounds like the session is only replicated when the server
ist shutdown/restarted/app reloaded. It also doesn't specify what
is replicated - the complete session?
Any suggestions?
Thanks in advance
