Compile error for FileReader

[VbEndUser]

Dear Gurus,

i have a question here.
I'm developing a mobile program using netbeans IDE. Because the application need to store data so i use FileReader. But when i code my application using FileReader's member function/variable, i have error. My IDE not able to find the symbol of FileReader.

The platform for my application is CDLC/MIDP.
I have import the Java.io.* in the beginning of the file.

My question is:
1. Can JDK1.5 library add in to the CDLC/MIDP platform? If can, can you show me how.
2. If not using FileReader, what other library that i can use to manage the data in a mobile application?

Thanks.
