Had the same problem. I reinstalled Java 7 as the default, and made sure that it was the first java.exe referenced, in the path.
Oh I see, a year ago I found okay, but now anything was wrong.
Well, I have installed eclipse with newest java. what should I do then to keep both of them? is it possible? pls suggest me for better action.
Thank so much for your response, mate, I do appreciate it
# if only that way I can use my beloved jabaco, I would remove ecclipse
There might be different ways of managing your Java versions, but I install the different versions in different folders.
For the main version that's used most of the time, I select c:\java for the home (Sometime back, Groovy had problems with installations containing spaces in their PATHs, so I got into the habit of using c:\Java).
You can install the other JDKs in the default folders. Then, when you need to switch to any of them, modify the relevant environment variables like JAVA_HOME, JAVA_CMD, the PATH etc., to point there.
For convenient environment editing, I use Rapid Environment Editor,

Apologies to Manuel (thanks for everything, sir), you might also want to look into B4J. For this type of coding, I've pretty much moved to that platform. It's matured a great deal in the past year, and you might find it convenient.
