3DES Encryption

Can some one help me with a sample program for 3DES encryption
decryption using java cryptographic extension?

Can you please tell me how to generate a key from a static string?

The JCE documention is a bit complex and covers too may things
together. It's a bit complex to understand that how I can specify
algorithm specific keys.

Thanks in advance.

There are a lot of examples in the web available. You are probably only
missing the right keywords. Try:

desede jce example

Read the string, convert each two characters to one byte and create an
DESedeKeySpec() from the byte-array.
