RE: [PATCH] Clustering members using UDP sockets instead of multicast ones
Filip,
This is a very useful thing for those of us who have to contend with firewalls and
multiple datacentres.
If it can't go into the main CVS area can we have a 'standard extentions' type area
where things like
this can be kept with instructions on how to install ?
Thanks
David

thanks for the patch, I am not submitting this to CVS as I don't see that
much added value. But if others find it useful, this is configurable anyway,
so there is nothing hard coded in the current code about the membership.
hope that is ok.

Subject: [PATCH] Clustering members using UDP sockets instead of
multicast ones
Hi,
I'm testing the tomcat5 cluster in an environment where multicast
connections are filtered. So in order to test our implementation in a
cluster tomcat, i created this little UdpService that is heavily based
in McastService, but the cluster nodes are specified in an attribute as
comma delimited instead of been discover. It is not intended to be a
fast, it is only for testing. Perhaps somebody wants for something, and
keep doing this great work.

Re: [PATCH] Clustering members using UDP sockets instead of multicast ones
I agree with you. But instead of extending multicast service, I would create
a completely separate membership service. I am about to change how the
configuration file looks and at that point I would be more than happy to
have more than one supported configuration...so give me a couple of weeks.
In the meantime, why don't you just post it to the tomcat-user and who ever
wants it can use it.
