Hi there,

i'm trying to access a website from java over https. However the
certificate is self-signed and also expired (this doesn't matter since
this is only a developement server). To bypass the default security
manager which doesn't allow me to access this site I have written the
following code. However i get an runtime error saying that the
KeyManagerFactoryImpl is not initialized. I'm an absolute java beginner,
so any help is highly appreciated!

kind regards
Maros
