RE: [ebxmlms-general] freebXML MSH Scalability

Ajit,
 
Regarding point 2, I've already tried once to implement this and it
works. Since all j2ee servers support this and even tomcat and jetty
have connectionpool mechanisms, I'm all in favour of using that what is
provided with the appserver/servlet enginge. What I did not try is to
make it configurable to be able to use both solutions. This would
require a DBConnectionPoolInterface. Since hermes uses a combination of
a connection pool and some direct connections, getRawConnection(), I
mapped the implementation of these methods to the connectionpool. 
 
Another thing I was looking at was a real persistency layer (in it's own
package?) as interfaces which would make it possible to also store the
messages in the database as blobs (our ASP does not allow us to store
'things' in a filesystem).
 
Unfortunately I had a major system crash and lost all of this code and
did not start over again... 
 
Failover is also not possible (i think) since the message sending
threads (for retries etc) are created on a restart of the server, so if
one crashes you have to restart the other to have it pick up the
messages.
 
One of the other things (for us) is centralized authentication using an
ldap server where we can manage all users/clients/systems that have
access to the server. I'd like an abstraction layer for this to so we
can implement something that uses the authentication of the application
server / servelet engine (e.g. through jaas)

Hi,
 
    Hermes MSH is essentially a JAXM servlet with a lot more behind it.
 
    My question is - how does/would hermes scale w.r.t messaging
requirements?
 
    1. Can hermes use administered components such as datasources,
connection pools etc (other than hermes' native connection pools).
    2. What conversational state is preserved in a servlet instance of
hermes MSH? Can different instances of Hermes MSH share the same
underlying resources?
    3. What are the other key considerations w.r.t deploying hermes MSH
in an app server ( e.g. weblogic) cluster?
 
    Has someone experimented with this?
 
regards,
Ajit

Ajit,
Ooops.. you are right. We will include it in our next release. Thanks
for your suggestion.
Regards, -Patrick
 

    By the way, why is the SMTP port not configurable in
msh.properties.xml? 
 
      <SMTP>
        <Host>localhost</Host>
        <User>ajitkt</User>
        <Password>nainital</Password>
      </SMTP>
