我的jdk可能是安卓的

你好：

通过截图就可以看到  import java.io.IOException; 

导入java的io包都出现错误提示，说明这个机器没有java的编译环境，原因有2点：

1. jdk安装错误。
   

2. 本机环境变量没有配置正确。

此外还看到最后一个数据库SQLserver2008安装后，TCP/IP应该为“已启用”状态，

然后在IPAll中“TCP端口”项应为1433，不应该是空。设置完后记得重启机器。

你好：

刚刚测试了一下光盘内的代码。并没有错误，请仔细检查本机的环境。

此外有关数据库的安装和使用问题，可以去数据库专区进行咨询。

我还没装sqlserver，重装了系统，重新装的客服qq发给我的jdk和eclipse-jee-neon-3-win32-x86_64

但是还是找不到包

出现这个错误可能是服务器运行时库找不到了，您在项目名称节点上，单击鼠标右键，然后选择“构建路径”/“配置构建路径”菜单项，在打开的对话框中，选择“库”选项卡，然后看看有没有带红X的项，如果有，就应该是没有找到对应的库。如果是Tomcat那项上有红X，那么把它删除，然后选择添加库按钮，在弹出的对话框中选择 Server Runtime，之后单击“下一步”按钮，再选择您电脑中安装的Tomcat版本一致的项，之后单击“完成”返回到之前的库对话框，再单击“应用”按钮应该就可以了，如果还有JRE上也有红X那么，再选中这一项，然后单击“编辑”按钮，在弹出的对话框中，选择您 电脑中安装的JRE的版本即可。

如果再有问题，您把这库选项卡的界面截个图贴上来，我们再看看。

刚刚瞎点一顿不报错了
