Java Base64 Encode with Amazon Services-Collection of common programming errors

I am using exact code from here:
http://docs.amazonwebservices.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/AuthJavaSampleHMACSignature.html

to generate a signature for my application. However, one line of code is not recognized in Eclipse

result = Encoding.EncodeBase64(rawHmac);

Eclipse is saying it does not recognize the “Encoding” class. This is the exact error: The method EncodeBase64(byte[]) is undefined for the type Encoding

I’ve tried importing the following 3 things:

javax.sound.sampled.AudioFormat.Encoding;
org.apache.commons.codec.binary.Base64;
org.omg.IOP.Encoding;

However all three of these then tell me they don’t recognize the ‘EncodeBase64’ function. Does anybody know what import im supposed to use for the code linked above?
