Applet throws SQLException

Question

I have simple applet where a user clicks a button, which runs a stored procedure on a SQL database. The code that runs the SP is in a different class.
In my applet I am trying to create an instance of that class and run the method that executes the stored procedure.
The applet code is:
public class clsButton extends Applet implements ActionListener
public void init ()
Button btnRunSp = new Button("Run Report All-YTD");
setLayout(new FlowLayout(FlowLayout.CENTER));
add(btnRunSp);
public void actionPerformed(ActionEvent ae)
sqlSPResults sqlRs = new sqlSPResults(); //Class for SP
sqlRs.sqlRun(); //method that executes the SP
The error I am getting is: "java.sql.SQLException; must be caught or declared to be thrown" and it points to the "." in sqlRs.sqlRun();.
I have the throws SQLException statement on the method in the class I am trying to call:
public class sqlSPResults
public static void sqlRun() throws SQLException, IOException
Not sure why the throws statement on the underlying method is not recognized and not sure how to solve the problem.
TIA,
Todd

Answer 1

The "throws" clause on that method is recognized, and it is exactly that clause that requires your code in the clsButton class to catch the exception. To fix this problem, you usually have two approaches, as the error message says. You can catch the error, like this:try {
  sqlRs.sqlRun(); //method that executes the SP
} catch(SQLException e) {
  // code that deals with an SQLException
}Or sometimes you can declare that the method containing the line of code throws SQLException. In this case, however, you can't do that because you are implementing the actionPerformed method and you can't change its signature that way.
You will also have to do the same for IOException, which is also thrown by the sqlRun method.
