Hallo zusammen,
da ich Anfänger bin, verzeit mir bitte folgendes Problem:
Ich habe mir Eclipse runtergeladen, dort ein Projekt heruntergeladen und eingefügt und will dieses nun starten.
Dort bekomme ich folgende Fehler:
Exception in thread "AWT-EventQueue-0"
java.lang.NullPointerException

Mir wurde mitgeteilt, dass dieser Fehler daran liegt, dass ich JRE und nicht die JDK als Startumgebung nutze.
Von der Java Homepage habe ich mir JDK heruntergeladen (http://java.sun.com/javase/downloads/index.jsp) und installiert. Unter Eclipse habe ich aber nur weiterhin (Run as etc.) JRE zur Verfügung.
Was mache ich falsch?
