title: java not found after install but java programs run
body: <p>I updated my java to JDK 7 today and after installing I can run java programs and eclipse runs fine but <a href="http://www.java.com/en/download/installed.jsp" rel="nofollow">http://www.java.com/en/download/installed.jsp</a> says no working java detected. Also Minecraft won't log in and tekkit cant load anything from the internet.
  I have tried adding java to the PATH variable to no avail. What am i missing?</p>
