Hi,
I am trying to write a simple midlet for Sony Ericsson S710 phone (CLDC
1.1, MIDP 1.0, MIDP 2.0) where I try using FileSystemRegistry for
listing file system roots. The midlet runs ok on the simulator but gives
a NoClassDefFoundError for FileSystemRegistry.

I tried following -
Try to package all the jsr75 class files along with the midlet jar. The
phone does not like this (a message - can not create class in system
package is displayed). I tried signing the jar using the Ktoolbar that
came with the SDK from sony ericsson.

I eventually need to read and write files from the memory stick. If
JSR75 is not supported, how do I do achieve this (file system access)?

Thanks,
Abhijat
