NullPointerException when trying to programaticaly install a bundle in Equinox?

I ran into this problem as well, and I found that you don't get this error when using apache felix instead of equinox as the OSGi framework.

I'm trying to do a simple demo where I start the Equinox Framework and then load a tutorial bundle that was created (via the tutorial). I keep getting NullPointerExceptions here is the stack trace...

I ran into this problem as well, and I found that you don't get this error when using apache felix instead of equinox as the OSGi framework. It's not really an explanation, but switching to felix might be a possible workaround.

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.
