Every time I click on my project shortcut I get an error message from Java Web Start “internal error, unknown message”. I have tried many different ways of structuring my shortcut with the same result. I have opened the Java Cache Viewer and I can see my project listed there. I can run it directly from the cache viewer. If I delete the application from the cache, then launch it from the Ignition home page, Java will launch it fine and create a new shortcut on my desktop. The new shortcut will give me the same error message when I try to launch my project with it.
I have tried uninstalling and re-installing Java many times. I have the latest version. I have also uninstalled and reinstalled Ignition.
From what I recall, this behavior started when I tried to launch a project from a command line in a batch file. I got the error then and now I get it every time from all shortcuts using javaws.exe. This happens only on my development laptop. My real gateway on the server works just fine, although I never tried the batch file thing. I was too scared after it blew up on my laptop!
Anyone out there that can help?
