Reading from a Recordstore doesn' t work (+Code)

I want to read from a RecordStore, but I don't get any data, why?

Here is the sourcecode:

try {

db = RecordStore.openRecordStore("Klamauk", true);

byte [] record1 = new byte [100];

ByteArrayInputStream bais = new ByteArrayInputStream(record1);

DataInputStream dis = new DataInputStream(bais);

try {

in = dis.readUTF();

}

catch (IOException ioe) {

System.out.println(ioe);

ioe.printStackTrace();

}
