OTA installation involves a JAD file and a JAR file.
JAD file is usually dynamically generated by the servlet. Some possible errors that could be encountered in the process:
- Empty line in JAD
- Empty values in the property key-values
- Subdomain used in the Jar-URL
The solutions are obvious. Note to (3): Full domain would work fine, but static IP would be better since DNS does not need to be resolved and it would be faster!
