Encryption problem (java.security) *newbie*

Hi,

This is my first time building j2me application.

In my project I required to use ecryption.

I'm planning to use PBEWithMD5AndDES in j2me application using netbeans 5.5

However, when I try to import

java.security.Key;

java.security.AlgorithmParameters;

java.security.SecureRandom;

java.security.spec.AlgorithmParameterSpec;

java.security.spec.KeySpec;

the package can't be found...

please help, any help would be appreciated.
