we have a J2ME application using the record store functionality. It work fine if the deploy this via cable to a Nokia 9210 and install it in the midpui (MIDP_beta_sw_for_9210.sis) from file.

If we deploy it via OTA the application start successful on the device and work fine until the midpui will be closed. After that the jar-file will be deleted from file system.

We have two fixes for this problem:
1. Don't remove the application and deploy it once more (over OTA).
2. Close the application (not the midpui) and start the file browser. Go to the application directory and set the jar-file read-only.

Both fixes are not really fine. Did anybody knew another?

Thank you for your time,
