Is there any persistent storage for mobile application of J2me, like SQLite? If there is then please share the link or some example code of interacting a simple J2ME application with back end persistent database.
Yes, there is persistent storage for J2ME - called RMS (part of MIDP 2.0) - look here for short tutorial. RMS doesn't related to SQL, it's just for persistency.
if you're looking for SQL alike storage - read this discussion. Hope it would be helpfull.
