Hello, Firstly for those who don’t know, I’m the one responsible for the Web Sign On project since Kieran left, and have been keeping it quietly ticking along since. A fairly simple question really: what version of Java do you use in your SSO enabled application? More specifically, do you use Java 1.4 or a newer version (Java 5 or 6)? I ask because the SSO Client and UserLookup libraries are both written for Java 1.4 for maximum compatibility, but if nobody is using 1.4 anymore then they could be changed to take advantage of new Java features. If you are still on 1.4, it would be useful to know if there is a specific reason. Any feedback either way would be very useful. Thanks Nick elab
