In future when you post code, please use[code] and [/code] tags as described in Formatting tips on the message entry page. It makes it much easier to read.
The error is happening here
rs2 = max.executeQuery("Select max(PinNo) from Customer");
rs2.next();
String maxValue1 = rs2.getString(2); // WRONG!You can't get the second column (2). There is only one column in that result set. It should be getXXX(1)
And that's another thing. What in the holy hell are you doing here?
String maxValue = rs1.getString(1);
int maxx = Integer.parseInt(maxValue);
int max1 = maxx+2;Sillyness.
int max1 = rs1.getInt(1)+2;Finally you should look into using PreparedStatements. http://java.sun.com/docs/books/tutorial/jdbc/basics/prepared.html
