Thanks for the reply.
I meant to ask another question about signing jar. Do I need to sign the final jar ? I don't see that it's required.
Also, as in general for paid apps, how does Intel Appup Store allow users to try before they make purchase ? Does a developer need to provide a license key to unlock the full version for paid apps or the Store has some way to allow users to try before purchase ?
Concerning users trying apps: end customers have a 24h grace period in which they can cancel a purchase. See AppUp FAQ:
Well, we don't really want them cancelling purchases...now do we? Write excellent apps and that's not a problem. Quality, not quantity.
I observed the same behavior as well, perhaps this is a bug?
I had this as well; essentially I had jdk1.6.0_17, but I had to download the latest jdk1.6.0_23 before it would work.
Thus I assume there is a dependancy to minor version as well as major 1.6.
This includes the task like Saving the files to disk,open a file and executing a program outside of the jar.
