#250 Eclipse plugin problems

[Hoggard]

The interactions panel in the Eclipse plugin is not working correctly for me. In Dr. Java, I type the following:
String s = "hi";
s.substring(1);
and the panel correctly responds with "i". In the Eclipse plugin, however, there is no response from this.
Also, in the following:
String s2 = s.toUpperCase();
s2
works correctly in Dr. Java, but in the Eclipse plugin, responds with an error message stating that "s2" is an undefined name.

I have exactly the same problem. Any feedback will be very helpful. How do I get the Interactions pane to recognize the classes of my project?
