Hello,
I don't know whether you find your answer or not but I was trapped in this question from last 5 months. I made one Application which import all data into Record Store.
For these, its simple concept.
You connect your Midlet to Servlet. Servlet will retrive your data and send back to Midlet. You read this data and same time You add these records into Record Store.
These what I have used. Its working fine unless WaitScreen Issue.
SyncML is hope but still its not implemented for J2ME.
I can tell that still no concepts are implemented in Real.
