我在這裏很疲倦，在jsp中顯示JTable中的數據，但它總是在撥號框中顯示錯誤，如「與服務器通信時發生錯誤」。 我是新來的ajax jquery如何顯示數據給這種友善的幫助？jtable不顯示jsp中的數據它顯示錯誤

的Servlet：

System.out.println("inside========");
// Fetch Data from Student Table

int userCount = t.getStudentCount();
// Convert Java Object to Json
String jsonvalue="";

obj1.put("users", s);
String resp = jsonvalue+"("+obj1.toString()+"TotalRecordCount"+ userCount + ")";

**java class:**

System.out.println("dao========>"+dao);
daos.add(dao);
}
}
catch (SQLException e)
{
System.err.println(e.getMessage());
}
return daos;
}
**My response are**
response are====>({"users":["Dao [id=145, name=ammudha, job=appa]","Dao [id=146, name=sgfs, job=sdfsd]","Dao [id=147, name=null, job=null]","Dao [id=148, name=null, job=null]","Dao [id=149, name=null, job=null]","Dao [id=150, name=null, job=null]","Dao [id=151, name=null, job=null]","Dao [id=152, name=null, job=null]","Dao [id=153, name=null, job=null]","Dao [id=154, name=null, job=null]"]}TotalRecordCount51)
數據從servlet的來，但同時JSP加載到出錯
