title: Decode base64 String Java 5
body: <p>Is there a straight forward way to decode a base64 string using ONLY THE JAVA 1.5 LIBRARIES?</p>
  
  <p>I have to use Java 1.5 due to cross platform compatibility issues between Windows and Mac OS X (only Mac 10.5 supports Java 1.6, everything lower than 10.5 has Java 1.5 as default). </p>
  
  <p>The object "sun.misc.Base64Decoder" exists in Java 6, but not in Java 5.</p>
