[毕业设计出大麻烦了,心急如焚啊]tomcat http statu 500错误!请高手指点迷津!!!
我在tomcat root目录下建立一个bem的文件夹,里面有一个名为index.jsp的文件,在浏览器中输入地址: http://127.0.0.1:8080/bem/index.jsp 看到下面的出错信息.(我的jdk是1.6.0版本,也装了ms sql 2000 for jdbc和jdbc sp3,昨天在Dreamweaver 中可以预览jsp文件,今天不行了,老弹出 "未命名站点 1 的站点定义为 "的窗体)

------解决方案--------------------
java.lang.NoClassDefFoundError: com/microsoft/jdbc/base/BaseDriver
是不是没有找到mssql的驱动啊
你看一看有没有加载驱动
[解决办法]
找不到文件 java.lang.NoClassDefFoundError: com/microsoft/jdbc/base/BaseDriver
[解决办法]
驅動問題，你演示是不是在本機上進行的?
[解决办法]
你在index页引用了com/microsoft/jdbc/base/BaseDriver，但是在实际路径下找不到，你去查找一下你的一用问题
[解决办法]
驱动程序的URL根本不对，
[解决办法]
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ");
private static final String URL= "jdbc:sqlserver://localhost:1443;databaseName=Master;user=sa;password=sa ";
