Matching that decryption is very easy in Java using the JCE ( http://docs.oracle.com/javase/1.5.0/docs/guide/security/CryptoSpec.html ) . If you have worked with cryptography before then you will find the specification enough but if not then you would do well to buy a book. A good introduction is given in "Beginning Cryptography with Java" written by David Hook published by Wrox.

Note - for the work you are doing PKCS7 padding is equivalent to PKCS5 padding and you should specify PKCS5Padding when creating the Cipher object.
 
Don't get me started about those stupid light bulbs.
