Oh, I'm sorry. I should have marks the problem's line number.
Well the line 58 in PlotURGScan.java is:
I'm sorry if I'm wrong, but I guessed the error message is because the array is somehow detected empty or something. But the coordinates printed right before the error occur is from the same array. Therefore I assumes that it is because of the threading in Java Applet (which is still a mystery to me
).
I'm still having the same problem, so do please help me.
Thank you.
