title: Can I use Java 7 with Eclipse 3.x?
body: <p>I am trying to config my eclipse (Helios) use jdk 7 to compile my code. I didn't install jdk 7 on my Windows XP. But I include all of the jdk contents with my project. It seems the solution provided in <a href="https://stackoverflow.com/questions/4638108/how-do-i-configure-eclipse-to-make-use-of-different-version-of-jdk">this post</a> doesn't work. Compile java code needs JDK. the JRE is enough for running the compiled code. I think we need a way to configure the JDK to be used not just JRE. I tested with a JDK 7 new feature, String in switch, I can compile it in my batch file compile system but cannot use eclipse to compile it. </p>
  
  <p>any idea?</p>
