Can I supress the loading dialogs in Java Web Start?

Yes, use the -nosplash option. Place this: -nosplash in your JNLP document.

Or you can use your on startup image: MyProject1.0 My Company. Application Launcher For MyProject1.0 ....

Note, that for production use you might want the visual feedback to users, to avoid the "It doesn't work today" (where a big update must be downloaded over a slow line resulting in long startup times).

What I'd like to do is to have the feedback be in my page instead, the only reason I'm even using WebStart is because it loads in a separate process and hence won't hang the browser. – user134600 Jul 19 '09 at 5:08.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
