这是我的bean,放在WEB-INF\CLASSES\COM\XML下面
DataSource.java

public String sql; /*定义sql语句*/
public String param[]; /*查询条件,或者是新的记录*/
public ResultSet result=null;
public Connection conn;
public void setParam(String[] param)
{
this.param=param;
}
public void setsql(String sql)
{
this.sql=sql;
}
public void setConnection(String driverName,String URL,String username,String psw) throws Exception
{
Connection conn1;
Class.forName(driverName);
conn1=DriverManager.getConnection(URL,username,psw);
conn1.setAutoCommit(false);
this.conn = conn1;
}
/*获取查询结果*/
public ResultSet getResult()
{
try
{
PreparedStatement select_stm=conn.prepareStatement(sql,java.sql.ResultSet.TYPE_SCROLL_INSENSITIVE,java.sql.ResultSet.CONCUR_READ_ONLY);
if (param!=null)
for(int i=0;i<param.length;i++)
select_stm.setString(i+1,param[i]);
result=select_stm.executeQuery();
}catch(Exception e){System.out.println(e);}
return result;

这是我用bean的页面

bean.setParam("where name='admin'");
bean.setsql("select * from users");
ResultSet rs=bean.getResult();
out.println(rs.toString());

在eclipse里编辑时就出错,
bean.setParam("where name='admin'");
bean.setsql("select * from users");
ResultSet rs=bean.getResult();
这三行提示无法解析bean
运行不了..浏览器报如下错误
