J2ME Problem

Hello,

I am new to J2me and indeed new to Java. I know other languages such like VB,PERL,ASP etc. After doing some study now I know what is a midlet and able to create simple midlets.
While learning from Net, I come to know that there is no LOCAL FILE support under J2ME and what we can use for storing data is RMS.

I want to create a midlet which use some predefined delimated values in three diffrent sets like 3 different plain text files. As per user's input (user will provide input by selecting the options in a multiselect listbox, created with one dataset described earlier.) it will show related record(s) after some calculations with that.

Please guide me how I can do this ? I tried and found that I can add text files as resource with WTK. and also got success to load the file in Midlet. But that was complete file. I want to load it Line By Line.

Thanks,
Kirtimaan
