Problems with interoperability: MCrypt AES PHP x Java

Hi, I am having problems while trying to decrypt an encrypted string (generated from a java system) in PHP. To take external factors out of the way I decided to make them work first in my local system. So I've created a sample encrypt/decrypt from PHP (using mcrypt's extension) and the java code found at http://java.sun.com/developer/technicalArticles/Security/AES/AES_v1.html. I've added a System.out.println("KEY: " + asHex(raw)); to get the key used in the java and set the same in PHP. There is no mention in Java but since I didn't see a initialization vector I assume we are use ECB mode. Unfortunately the same string /key produces different encrypted values.
