OpenSAML user discussion

[Paul Hethmon <>]

You might be able to use something like Retroweaver. I can't remember
whether that will take care of everything or not, but it's about your only
choice.

Given the Java 5 is already End of Life, it seems like its time to consider
upgrading anyway.

God does not play dice with the universe; He plays an ineffable game of his
own devising, which might be compared, from the perspective of any of the
other players, to being involved in an obscure and complex version of poker
in a pitch dark room, with blank cards, for infinite stakes, with a dealer
who won't tell you the rules, and who smiles all the time.

 -- Terry Pratchett, Good Omens
