I am not familiar with the Axim x30 but the answer is probably not.
Java applications run in a sandbox that basically restricts any access to real hardware like a WiFi card. Generally speaking you can't read or write to files either. You can't even interact directly with other Java programs.
MIDlets are designed to work with the display, keypad, and remote servers. That's basically it. Newer JSRs and custom APIs on some devices allow additional capabilities like accessing a camera, serial port, Bluetooth device, GPS receivers, or media player. Those are the exception, not the rule and often times access to those capabilities are restricted in some way.
