Do something like this.Start a demon thread every time the application is starting for the first time to check in the server if there is any available updated version of your midlet.

thank you for replayingI developed an app which used xml file. And when I want to moify it, I only modify it's xml file. So I want my users only download the modified xml file. So is it bossible?thanks againg

well it is possible to download the xml file. but I figured it out that u need it to be stored in the app rather than every time get it downloaded.so u need to store the contents of ur xml file in the recordstore. I don't see any other option dude.

find_suvro@SDN is right.

you should create a parser that initialise the application with an xml file or anything else.

the MIDlet will construct itself with the configuration file. when a new config file is available,

you can create a prompt window to ask to the user if he wants to update the MIDlet.

if true, you download the new xml file and the MIDlet automatically recreate the GUI...

good luck

the jad file is used to install the app on your mobile...

when i say 'configuration file' i mean that your app is looking at each starting on the web

server to see if a new config file is available. if it's true, the app download it and rebuild

itself.

the config could be a txt file, an xml file, a serializable object,...

the job is:

MIDlet -> asktotheserver

|_ <yes> : download the file and parse it to create new design and store the file in the RMS

|_ <no> : load the config file from the RMS and and parse it to create the app

good luck
