use an sms service provider e.g. clickatell with xml over http

First get a HttpUrlConnection and then get the stream and send the xml in the
stream, get input stream and read the response.

whats the point in using xml/http, i dont understand where xml comes into sending an sms from a servlet.

thanks

1:first you are not sending the sms from a servlet.
2:you are sending it from the sms server.
3:the servlet connects to the sms server

3:
user enters details into form and hits button
form goes to servlet
servlet reads data from the form
servlet gets http connection to sms server
servlet uses data from form to create xml
servlet sends xml over http to sms server
sms server sends message to desired number

this is an example of what xml was designed for, if you don't understand this
you have missed the whole point of xml.

xml was designed to be a ad hoc method of storing data, so that it could
be understood be different languages/application

the details you enter in the form are converted to xml so that the sms server
can understand the information.

example
you enter in the form
number=123
message=my message

so when the servlet gets this info it then passes it to sms server. but how
simply send "123 my message" or "my message 123" or "number=123message=my message"
this is why xml is need the sms server has a dtd describing how message should be send
<xml>
<num>123</num>
<mess>my message</mess>
</xml>

I dont want to start a new thread so ill ask here.I asked about sms sending, thats fine.Im familiar with javamail and connecting to smtp servers but would it be possible to connect a servlet to a pop3 server and have it run indefinately or periodically to check for new email?if servlets are not a good idea what would be the best approach?
please help!

servlets are not designed for this.

servlet recieve a request and send a response,it is a 1 time thing.

what you could do is set a refresh header in the servlet reponse,
so that the servlet sends the reponse to the browser and then
recalls the servlet at the given refresh rate.
this would be like hitting the refresh button on the browser ever few
seconds and recalling the check mail servlet.
it is not an idea option.

you can also use a javascript timer function to call a check mail servlet
every few minutes

most webmails apps need you to hit the check mail button to check for
new mail, rather that the application checking for you.

thanks for that reply.i suppose servlets is not the way to go, as it seems to messy.Is there any other option?i have tested out the o2 sms email notification, would love to know how that works!is it possible to do this anyway besides servlets?
thanks again

what ive decided to do is have a program running on a designated machine that constantly checks a POP3 server and then notifies a servlet if email arrives.the servlet then dispatches notification to a user.thanks for the help
