Hello, I am in the beginning of a project and I could use any help possible since I am not yet familiar with mobile phone technology as a developer. I have a java web service that receive a request object with few attributes (lets say height, age and sex) and returns a simple response object (lets say the ideal weight in kilos) (xml,wsdl etc).

What I want to do is a java ME application, distributed it for final users mobiles, that will generate, after inserting the data, a SMS message and send it in a number that I will be able to catch the message (SMS Gateway ?) and just write it down to a database. Then a daemon Java Program will come and check the db for new entrees, and if found create a new web service request from the data and as a client will get the result from the provider. Then it will fire up a SMS message to the users mobile phone number that the request message came. I am thinking this approach because very few of the potential end users have access to internet through their mobile.

Notice that in the end of my research I will have access to a SMS Gateway but now I don’t know match about it. I am wondering how to begin, should I get familiar with a Java SMS Library like SMSLib or to go from the start to a SMS gateway like Kannel? Most important I would like your opinion about how to solve this problem, is the approach I explained accomplishable and straight forward or should I try something else?

Thank you in advance for your responses (and sorry for my English as I am not a native English speaker).
