Hi all. I have JDK 5.0 installed in my system and wireless toolkit 2.1 trying to run sample midlets from WTK or some articles, I got a long assembly stack trace and java.lang.ClassFormatError can I run (WTK) or develope midlets on JDK 5.0 ?? does any rancher here use WTK 2.1 and JDK 2.1 together ? I am happy with Tiger, I don't want to use JDK 1.4 again. any ideas ??
