Good stuff comes packed. JSLEE 2.0.00B2 and MMS news

Its been a while since I had a time to post here. Made myself a promise to post quite few usefull tips regarding JSLEE 2.x but never had time. Why? Because Mobicents team worked quite hard to be able to deliver good news.

So first thing. SLEE 2.0.00B2 is about to be let loose into community!
Made a lot of effort to make it quite a pack.
- HA/FT clustering API
- new HA api for RA implementation
- full replication of data and clustering of JSLEE servers !!!!
- performance improvements
- SIP11 RA tunning(more and more cps)
- BUG fixes

Each topic deserves separate post, once I have a second, I will do that with details and examples guide.

HA/FT clustering API(topic for another post) has ben created to ease development on this "side of moon".  It allows quite easy plugability into cluster, making application aware of changes. It is based on JBoss Cache and supports different replication strategies. I will describe it a bit more deeply in another post. If someone feels a desire to play with it I recomend browisng and playing with repository. So far we created a standalone, distributed timers(not tied to any of our project) it is quite good alternative to EJB3 timers and other implentation available(I would say its so far a best sollution, but...).I will describe example in another post(if someone feels like playing in a dark this will help.).


SLEE 1.1 specification is a great improvement since 1.0. Changes are quite significant so I even doubt why its 1.1, not 2.0, but thats just a speculation.  However, among all changes there is no definition of HA/FT api aside of Marshaller ( which is of no use without something specific to container). Thats why each implementation of JSLEE specification has to have some specific API to handle replication and FT in RA layer.
So, we had to do it. So far only SIP11 RA is aware of cluster. We have to make some more test, but its working and its quite nice feature, atleast after hours of coding its something that pays of effort.


Full replication. Yes, JSLEE 2.x container is FULLY replicable among cluster. There is no exception. Data and local server resources are handled properly to make SLEE developers work in unified enviroment, even though server runs on mulitple nodes.



Now what about MMS? Well me, Amit and Oleg took our time. All news will be official near release date. But what I can reveal is:
 - we are working on video and its going good
 - performance improvements - based on media path
 - SS7 enabled!, right now we are running test to see how SS7 link is stable, next are tests with CAMEL, ISUP, SCCP.


Thats it for now.
