java配置如下：
private Connection conn = null;
private Statement stat=null;
private ResultSet res=null;
// 数据库连接初始化
public Connection initConnection() {
try {
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
DataSource db = (DataSource)envContext.lookup("db2dao");
System.out.println("加载驱动！！！！");
//名称与web.xml配置中的一致
conn = db.getConnection();
} catch (Exception ex) {
ex.printStackTrace();
}
return conn;

//关闭数据库连接
public void closeConnection() {
if (conn != null) {
try {
conn.close();
conn = null;
} catch (Exception e) {
e.printStackTrace();
}
}
}
}

context.xml配置如下：
<?xml version='1.0' encoding='utf-8'?>
