Part of our internal systems have been setup to run on PDA's over a
webservices interface. The problem lies in that the parts of the building
the connection is a little flaky and connections to the WAP get dropped.
What im asking is what is the best way to deal with this and is there a best
practice ...

The medthod that I have come up with is to have a webservice calls in a try
catch block looking out for dropped connection, if a dropped connection is
found a sleep is called for 1/2 second and a recall to the webserice is
done. After 10 retries if the connection isnt reestabilished an error is
shown stating that the connection couldnt be established.

something like

repeat until connected or maxtries

try

call web service

catch soap error

connected  = false

is my method the best method ?
or are there better ways of doing this ?

Thnaks

Hello Jon,

   Sounds like you need to be using reliable messaging. go over to [0] for
an implementation of the WS specification.

Thanks for the link, seems the project is in very early stages as there is
limited information as of yet.

Maybe Im approaching this all wrong , Dilip your post seems to be about
message queues over web services, which isnt really what im looking for ,
I;m just looking for the best way to wait if a WAP point is droppe and the
client has no access.

What im now thinking is that it a network fault and not really a code issue
as a wifi network shouldnt be dropping - is that correct ?
