JSP连接SQL的问题,虽然是老生常谈,但是以前的相关解决方法都试了,还是没成功,不知如何是好!
程序:test.jsp
<%@   page   contentType= "text/html;charset=gb2312 "%>  
<%@   page   import= "java.sql.* "%>  
<%@       page       import= "com.microsoft.jdbc.sqlserver.SQLServerDriver "       %>
<html>  
<body>  
<%Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ").newInstance();  
String   url= "jdbc:microsoft:sqlserver://localhost:1305;DatabaseName=test ";  
//pubs为你的数据库的  
String   user= "sa ";  
String   password= " ";  
Connection   conn=   DriverManager.getConnection(url,user,password);  
Statement   stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);  
String   sql= "select   *   from   test ";  
ResultSet   rs=stmt.executeQuery(sql);  
while(rs.next())   {%>  
您的第一个字段内容为: <%=rs.getString(1)%>  
您的第二个字段内容为: <%=rs.getString(2)%>  
<%}%>  
<%out.print( "数据库操作成功,恭喜你 ");%>  
<%rs.close();  
stmt.close();  
conn.close();  
%>  
</body>  
</html>  

浏览后的出错提示:
