I'm trying to work with Hydra library (http://sourceforge.net/projects/hydra-mcmc/) in my NetBeans IDE, but it seems like IDE ''cant see'' the library at all. I've made a screen shot:
I've imported Hydra .jar file by clicking on "Libraries" and "Add a Jar". The packages are properly listed on the right (you can see it on the picture).
How to resolve this problem?
I've just downloaded the jar, and it looks like it's been packaged wrongly. As @Elliot says, the screen-shot shows the packages starting Hydra.
Maybe try importing
Hydra.org.omegahat.Probability.Distributions.UnnormalizedDensity and see if that works.
