OpenSAML user discussion

[lakshmi narasimhan <>]

Hello Alex,

I'm stuck with a similar problem. We have a Websphere application
server that is hosting other Java applications and has JDK v1.4. Now
if I need to compile the openSAML classes (Base64 class for example),
is there a way to get around the problem, without upgrading the JDK
version to 1.5 please?

Thanks,
Laks.
