That's what is so puzzling, I thought an appropriate upgrade would resolve the problem but it hasn't. In an effort to get something working I've come down to a very simple project, an Application Client module on its own, so there is just a jar.
I tried the upgrade to 3.1, clearing the cache and the webstart folder and so on, still with no luck. I also tried with NetBeans 6.8 but that made no difference. There must be something about my environment but what? It's all very strange.
