有一个文件depart.jsp。执行后错误。
tomcat服务显示执行sql语句错误[SQL在查询分析器执行好的]。
执行SQL语句出错: [Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'tbDepart'.
没办法，我建立另外一个文件测试[test.jsp]。
<%@page contentType="text/html;charset=gb2312"%>
<%@page import="java.sql.*"%>
<%@ page session="true"%>
<jsp:useBean id="connect" scope="page" class="com.fsk.DBConnect" />
<%

String sql_str = "select DID,DParent,DName from tbDepart where DType = '0' and DParent='0' order by DSort";
//out.println(sql_str + "<br>");
ResultSet rs = connect.executeQuery(sql_str);
while(rs.next()){
out.println(rs.getString(1));
out.println(rs.getString(2));
out.println(rs.getString(3) + "<br>");
}

%>
没问题。
然后我在把test.jsp 该名为 depart.jsp运行。结果出错。

请问这是什么错误，看不懂。
然后将depart.jsp该名字为departmanager.jsp。执行又好了。
这是否在tomcat服务器又残留的文件没有删除，还是怎么回事情。
