Help me running CryptoTest example

Question

Hi there..
I need a help with CryptoTest example. It can be found here: http://java.sun.com/developer/J2METechTips/2001/tt1217.html
I�m using J2ME WTK 2.2 + patch.
What should i do to build it?
At least, could anybody tell me a good tutorial that teaches how to use differents libs?
Thanks so much..
The source is it:

Could you try the following command:
asadmin user <username> password <password> deploydir c:\Sun\AppServer\samples\quickstart\build
where you replace <username> and <password> with the appropriate values for your setup. As noted in the quick start guide you do not have to provide the user and password options if you used the "Don't Prompt" option when installing the app server.
