我的第一个jdbc连接db2的程序

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class test1 {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub

String JDBCDriver = "COM.ibm.db2.jdbc.app.DB2Driver";
String DbSource = "jdbc:DB2:sample";

try {
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
Connection conn = DriverManager.getConnection(DbSource,
"用户名", "密码");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * from sales");
int i = 1;
while(rs.next()) {
System.out.println(rs.getString(1) + " " + i++ + "n");

}
rs.close();
stmt.close();
conn.close();
} catch (ClassNotFoundException cnfe) {
System.err.println("Unable to load driver.");
cnfe.printStackTrace();
} catch (SQLException se) {
System.err.println("sql error.");
se.printStackTrace();
} catch (Exception E) {
System.err.println("other exception");
E.printStackTrace();
}

}

}

代码中使用的3个jar文件在db2安装目录（D:IBMSQLLIBjava）下，名称为：db2java.zip，db2jcc.jar，db2jcc_license_cu.jar
