与SQLServer 2008 R2的连接过程中发生了jasper异常

问题描述

|

<%@page import=\"java.sql.*\"%>

<form name=\"form\" method=\"post\" >
<b>Select a country:</b> </td>
<select name=\"sel\"><option value=\"\"><---Select---></option>
<%
Class.forName(\"net.sourceforge.jtds.jdbc.Driver\").newInstance();


Connection con=DriverManager.getConnection(\"jdbc:jtds:sqlserver://subversion/sql2k8:1433/career\",\"sa\",\"Cloud#123\");

PreparedStatement psmnt = con.prepareStatement(\"select * from country \");
ResultSet results = psmnt.executeQuery();
while(results.next()){
String name = results.getString(2);
 String id = results.getString(1);
%><option value=\"<%= name %>\"><%=name%></option>
<%} results.close(); psmnt.close(); %>
</select><br>

和随之而来的错误：

org.apache.jasper.JasperException: An exception occurred processing JSP page /1.dropdown_insert.jsp at line 13

10: 
11: 
12: 
13: Connection con=DriverManager.getConnection(\"jdbc:jtds:sqlserver://subversion/sql2k8:1433/career\",\"Cloud#123\");
14: 
15: PreparedStatement psmnt = con.prepareStatement(\"select * from country \");
16: ResultSet results = psmnt.executeQuery();

堆栈跟踪：

org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:519)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:410)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

    

解决方法

检查连接字符串-

jdbc:jtds:sqlserver

：// subversion /sql2k8

:1433/career

。 使用

try-catch

块和printstacktrace获取正确的错误消息。
