我想在年视图中为fullcalendar添加工具提示.我尝试使用下面的一个,但它在月视图中添加了工具提示.我试过谷歌,但没有找到任何与此相关的内容.有没有其他方法可以在年视图中添加工具提示？

eventMouseover: function(calEvent,jsEvent) {
            xOffset = 10;
            yOffset = 30;
            $("body").append(calEvent.tooltip);
            $("#tooltip")
                .css("top",(jsEvent.clientY - xOffset) + "px")
                .css("left",(jsEvent.clientX + yOffset) + "px")
                .fadeIn("fast");
    },
    eventMouseout: function(calEvent,jsEvent) {
        $("#tooltip").remove(); 
    }

嗨,当我尝试使用我的java示例代码连接oracle时,我是java的新手,我得到了上述异常

我的代码是

import java.sql.*;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


public class DbConnectivity extends HttpServlet {
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
    {
       try {
        Class.forName("oracle.jdbc.driver.OracleDriver");
        Connection con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:8080:orcl", "system", "tiger");\\ The Exception thrown here
        Statement stmt = con.createStatement();
        ResultSet rst = stmt.executeQuery("select * from users");
        System.out.println(rst.getString(1));
        stmt.close();
        con.close();
    } catch (ClassNotFoundException e) 
    {
        e.printStackTrace();
    } catch (SQLException e) 
    {
        e.printStackTrace();
    }
    }

}

抛出的异常是

java.sql.SQLException: Io exception: Got minus one from …
