Just to let people know: I'm writing a new Base64InputStream by using
the ws-commons-util logic, but rearranging things to suit this kind of
usage pattern:
#1. in = new Base64InputStream(in, DECODE);
#2. in = new Base64InputStream(in, ENCODE);
The ws-commons-util logic is really slick. I really like it. (And
it's so fast). This is a fun challenge. I'll post to the list in a
week or two with any progress.
yours,
Julius
