a.lang.Number,java.lang.Comparable,java.lang.Comparable) in org.jfree.data.categ

It's like the message says: the DefaultCategoryDataset class has two methods that would match the parameters that you're providing. Check out the javadocs of that class for details. You need to make it clear which of the two methods you want to invoke (although, actually, invoking either of them will have the same result). You can do this either by calling

dataset.setValue(new Integer(rs.getInt(1)), "Profit %", rs.getInt(2))

(which I'd prefer) or

dataset.setValue((double) rs.getInt(1), "Profit %", rs.getInt(2))
