OpenSAML user discussion

["Alexander Müller" <>]

Hi,

you could try to compile it with 1.4 and if it doesnt work try to port
it over, however I suppose upgrading would be easier.

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.
