这是咋了？怎么解决？帮帮忙

Answer 1

检查你的数据库连接，URL，端口，数据库inst是否正确用数据库的client端工具先连，如果连client端都连不通，还谈什么J2EE的应用错误呢？

Answer 2

端口没配置好。
开始==>所有程序==>microsoft SqlServer2005==>配置工具==>sqlserver configuration manager
照这样配置完，重启下服务器就可以了。

Answer 3

在我的电脑里 那个 管理里面配置那个TCP/ip 是否已经启用吧

Answer 4

错误可能是这个：
java.lang.NumberFormatException: null
at java.lang.Integer.parseInt(Integer.java:415)
at java.lang.Integer.parseInt(Integer.java:497)

Answer 5

开始菜单  sqlserver 配置工具 外围应用配置工具 服务和练级的外围应用配置器  databaseEngine1.把服务打开 2.远程连接选择TCP/Ip的

Answer 6

1.把服务打开 2.远程连接选择TCP/Ip的 3.重新启动数据库服务

Answer 7

SQLServer 的配置工具 有关 TCP/IP 都设为启用。 然后重启服务。 

Answer 8

严重: Servlet.service() for servlet jsp threw exception
java.lang.NumberFormatException: null

Answer 9

1、看看sql服务器有没有打开
2、检查端口是不是被防火墙挡住了
3、检查sql客户端的tcp/ip协议是不是没有打开

Answer 10

看异常要看最下面的 
严重: Servlet.service() for servlet jsp threw exception
java.lang.NumberFormatException: null
你的实体类属性 和数据库字段 类型 是不是有出入

Answer 11

你看看 servlet加载项里面是否初始化了数据库连接，然后就是看 是否采用了URL IP不通，端口号不对都会出现connection失败

Answer 12

打开sqlserver configuration manager ---》 网络配置 ---》MSSQLSERVER 的协议 --》将 TCP/IP 启用 

Answer 13

打开sqlserver configuration manager ---》 网络配置 ---》MSSQLSERVER 的协议 --》将 TCP/IP 启用
