jsp页面错误 大家帮看看是程序问题还是配置问题
我照网上的源码写了个数据库测试jsp页面
<%@ 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= "1983 ";
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>

我的tomcat5.0 ，sqlserver打的sp4的补丁，3个jdbc都放在了common/lib下，我把这个jsp文件放在了ROOT/下，运行就出现了这样的错误：
HTTP Status 500 -

这是哪里出错啊？
[解决办法]
建议调试步骤：
1、把charset=gb2312改为charset=utf-8，看运行结果（汉字可能会出现乱码）
2、把数据库操作语句注释掉，看运行结果，如果运行正确，则一步步缩小注释范围
[解决办法]
再检查下你的web.xml看看是否是gb2312
