Lock ICON on ACCESS DATABASE

Question

Hello there!
I am using javabeans to connect & disconnect from a database by calling the methods listed below. What i have noticed is that sometimes the jsp application refuses to disconnect from the database after executing a sql command such as insert, e.g
bean.connectToDatabase();
bean.insertIntoTable(item one, item two );// this method test if there is a connection before inserting.
bean.disconnectFromDatabase();
what i have noticed is that the lock icon appears on the msAccess database after running the jsp application. Do i need to close other stuff like PreparedStatments in my bean as well. Were is the leak coming from? Any ideas?
public void connectToDatabase () throws ClassNotFoundException,
SQLException
try
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
connection = DriverManager.getConnection (connectionURL, "", "");
catch (ClassNotFoundException e)
error = "ClassNotFoundException: Unable to locate database driver ";
throw new SQLException (error);
} // end try
} // end connect
public void disconnectFromDatabase () throws SQLException
try
if (connection != null)
connection.close ();
} // end if
catch (SQLException sqle)
error = "SQLException: unable to close the database connection ";
throw new SQLException (error);
} // end try
} // end disconnectFromDatabase

Answer 1

maybe try if(connection.isOpen() == true){
rs.close();
stmt.close();
connection.close();}
