Subject Re: [Axis2] SMS transport for axis2
Date Fri, 27 Mar 2009 03:03:27 GMT
Hi,

I'm currently evaluating  open source libraries that support SMPP and
debuging the Axis2 Http transport. I'm currently Woking with jsmpp.While
reading the SMPP protocal specification [1] and working with jsmpp [2] I
found out that In SMPP there is a way to archive reliability by having a
delevery report machanishm . (Note that this is Application layer
reliability) . But this feature may be avalible or not depending on the SMSC
( Short Message Service Center* *) that the transport is connecting.

So in Axis2 and Aynapse domain does application level reliability in SMS
transport add value? Any thoghts?

And aslo i would be glad  to get some feed back on realworld senarios that
users  will use this transport with Axis2 and Synapse.

thank you,
Charith
