修女重出江湖
小女子好段时间没学JAVA了,我的问题是JSP连接SQL2000有问题?
JAVA连接SQL成功,SQL打了SP4补丁,TOMCAT也能打开http://localhost:8000(因为先前8080端口据说被占用,我就改了),成功.jdbc驱动及路径都ＯＫ啊．
但我用的一个测试连接的JSP文件怎么就失败呢?请问各位大师!
注：我的sql_test.jsp是放在．．\Tomcat 6.0\webapps\ROOT 下
出错信息提示如下

以下是我的JSP文件
<%@ page import="java.lang.*, java.io.*, java.sql.*, java.util.*" contentType="text/html;charset=gb2312" %>
<html>
<body>
<% Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver")//.newInstance();
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pubs";
//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 job_id,job_desc from jobs";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) { %>
您的第一个字段内容为：<%=rs.getString(1)%><br>
您的第二个字段内容为：<%=rs.getString(2)%><br>
<% } %>
<% out.print("数据库操作成功，恭喜你"); %>
<% rs.close();
stmt.close();
conn.close();
%>
</body>
</html>
TOMCAT中LOG显示

[解决办法]
<%@ page import="java.lang.*, java.io.*, java.sql.*, java.util.*" contentType="text/html;charset=gb2312" %>
把里边的分开写一下吧
<%@ page lan...="java" pageEncoding="gb2312" %>
<%@ page import="java.lang.*, java.io.*, java.sql.*, java.util.*"%>
试试吧.没用过Tomcat6.0
[解决办法]
原因很简单，你的语句中使用的是中文的全角空格，把它们替换一下就可以了！
另外Class.forName 哪一行少了一个分号
<%@ page import="java.lang.*, java.io.*, java.sql.*, java.util.*" contentType="text/html;charset=gb2312" %> <html> <body> <% Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");//.newInstance(); String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pubs"; //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 job_id,job_desc from jobs"; ResultSet rs=stmt.executeQuery(sql); while(rs.next()) { %> 您的第一个字段内容为： <%=rs.getString(1)%> <br> 您的第二个字段内容为： <%=rs.getString(2)%> <br> <% } %> <% out.print("数据库操作成功，恭喜你"); %> <% rs.close(); stmt.close(); conn.close(); %> </body> </html>
[解决办法]
文件找不到错误~~改成<url-pattern>/hello </url-pattern>这样试试~~
[解决办法]
如果我没记错,你的项目启动的时候就会报错.url-patten里边的内容应该是以/开头
