Hi,
Im currently starting development on an online auction site (kinda similar to Ebay except way smaller). At the moment I intend using ASP and Access Database for content management purposes. The main feature I'd like to implement though is the ability to send SMS notifications of bids to users of the site (ie if a bid has been made for a "clock",send an SMS to the owner of the clock).
Id like to have an application on the recievers phone implemented in J2ME that they could use to reply to the notfication message( The owner of the "clock" could choose to 1)Accept The bid ,2) Reject The Bid, 3)Consdier Bid from a GUI and simply click some command named "SEND" on the application on thier phone...roughly speaking),
Im wondering
A) Can this be done with J2ME...How? and what tools do I need?
B) How do I get the J2ME application from the website to a remote user?
C) How will be able to recieve replies to the website?
D) Are there any issues with regards firewalls that I should be aware of?
Thanks in advance,
Triggerred

Thats great jimmack;
A few more questions(really silly ones):
Is there any eviroment I can test solutions for? (ie is there a way i can test for Nokia & Siemens Phones?
How does J2ME send a SMS message from the website to the users phone?
Do all phones I intend to deploy the solution have to support WAP?
>> Is there any eviroment I can test solutions for? (ie is there a way i can test for Nokia & Siemens Phones?
If you mean you want an external entity to test on multiple platforms, see http://www.javaverified.co
>> How does J2ME send a SMS message from the website to the users phone?
As I understand your question, your server will send the SMS (from the ASP code you've written). The J2ME MIDlet (application) will only receive SMSs.
>> Do all phones I intend to deploy the solution have to support WAP?
All J2ME compliant phones (MIDP-1.0 or MIDP-2.0) have WAP browsers built in. This method of downloading is part of the MIDP standard and therefore a phone without a WAP browser cannot be considered J2ME compliant.
Thanks a million jimmarck,
1 further question (sorry for annoying you). Is is posible to send a SMS to particular application on a phone? ( ie most SMS are sent an Inbox on a persons phone, would it be posible for me to send the SMS to the J2ME MIDlet (application) on the persons phone instead of sending it to thier Inbox)
i'm currently workin on sometin similar to this as well. I'm developing for user to send and receive as well. however, nw stuck with an error
javax.microedition.io.Conn
Could anyone please advice?
i'm using wtk2.0, jdk 1.4.2, wma1.1, midp2.0

>> Can this be done with J2ME.
Yes it can be done with J2ME, but only with MIDP-2.0 (which is only implemented on the newest phones).
>> How? and what tools do I need?
You need to create a MIDP-2.0 MIDlet. In order to do this, you'll need the standard Java Development Kit (JDK) from Sun (the latest version - 1.4.2 - should do http://java.sun.com/j2se/1
>> How do I get the J2ME application from the website to a remote user?
When you build a J2ME application, you get two files, a .JAD file (Java Application Descriptor) and a .JAR file (Java Archive). You need a WAP page that has a simple "<a href=..." link pointing to the .jad file. (Some phones support a direct link to the .JAR, but don't count on it).
>> How will be able to recieve replies to the website?
To *receive* an SMS from the website, you'll need to set up the push parameters for the MIDlet.
To *send* a response back to the website, you'll need to create an HttpConnection and then just use a URL like you would from a web browser (GET and POST are both supported).
>> Are there any issues with regards firewalls that I should be aware of?
Not that I can think of. Firewall issues should only really be relevant when the client is using a web browser from behind a firewall. Your clients will be using a phone for their connection.
