Error: java.sql.SQLException; must be caught or declared to be thrown.

Question

in a servlet, I have a class like:
class mydb
public static Connection conn;
public static void init() throws SQLException
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn = DriverManager.getConnection ("jdbc:oracle:oci8:@baby", "scott", "tiger");
public static String getValue() throws SQLException
String curValue="";
// Create a Statement
Statement stmt = conn.createStatement ();
// Select the ENAME column from the EMP table
ResultSet rset = stmt.executeQuery ("select ENAME from EMP");
// Iterate through the result and print the employee names
if (rset.next ())
curValue = rset.getString (1);
// Close the RseultSet
rset.close();
// Close the Statement
stmt.close();
return(curValue);
public static void destroy() throws SQLException
// Close the connection
conn.close();
but when it is called, errors "java.sql.SQLException; must be caught or declared to be thrown." encountered, how to solve this problem? please help.

Answer 1

This is part of the Java language.
If a method throws an exception, then
it is telling you that the exception is
something that you should be aware of.
If you call a method which throws this exception, then the method must either catch this exception, or you may decide that this exception should be caught by the calling method.
So, your choices are:
1. Wrap the method call in a try{...} catch block
-or-
2. Change the (calling) method's signature to reflect the fact that this method can cause this exception to be thrown (add a 'throws SQLException' ) at end of signature.
