我刚学JSP,现在在学连接数据库,但弄了很久还是出错.
我先下载安装了SQL server2000的JDBC驱动,然后把msutil.jar、msbase.jar、mssqlserver.jar三个文件复制到Tomcat 6.0 \lib目录下,在SQL建立数据库testDatabase,然后想运行以下代码:
<%@ page contentType= "text/html;charset=GB2312 " %>
<%@ page import= "java.sql.* " %>
<HTML>
<BODY>
<%
try
{
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ").newInstance();
}
catch(ClassNotFoundException e)
{
out.print( "类找不到! ");
}
String url= "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=testDatabase ";
String user= "sa ";
String password= "123 ";
Connection conn= DriverManager.getConnection(url,user,password);
%>
</BODY>
</HTML>
出现以下错误:
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: An exception occurred processing JSP page /jspstudy/selectUserTable2.jsp at line 17
14: String url= "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=testDatabase ";
15: String user= "sa ";
16: String password= "123 ";
17: Connection conn= DriverManager.getConnection(url,user,password);
18: %>
19: </BODY>
20: </HTML>
到底是怎么回事,请高手帮帮我,谢谢!
