Can't get the debugger to work

davidm88 — Thu, 05 Feb 2015 18:17:46 -0000

I'm working through a text book which suggests I use DrJava for the examples. I've had no problems so far and I'm now trying to use the debugger.

It says there should be a "debugger" drop down menu. There isn't. I went to preferences and it says the debugger is not currently available, try set the path of tools.jar in the resources tab. So I did that (I set it to C:\Program Files\Java\jdk1.8.0_31\lib\tools.jar).

I am using Windows 7 and DrJava Version : drjava-20140826-r5761. I will copy paste the full system details below.
