Hmm, I am not exactly sure what bits you are talking about.
Standard DES is a 64 bit block cipher and uses 56 bits key. The key
passed in is actually 64 bit with only 56 useful bits.

You can use triple DES which is using 128 bits key to increase security, but
it is not in JCE1.1. It will be in JCE1.2

If this does not answer your question, please feel free to ask again.
