I think that eclipse are unable to see the external .jar that my View.java (that lounched alone work fine) requires.

This looks like the pre 3.0 plugin way (older than 7 years!!!!)! You
should switch to OSGi-Usage!
Next problem is that you are using Swing and to embed this into SWT you
need to do extra steps using the SWT-Awt-Bridge.
Might I also suggest that you take a look at JavaFX 2.0 if you want to
3d stuff in Java?
I'd suggest you start with one of the many only tutorials on writing a
