在JSP我的登錄形式是：
servlet異常
<form method="post" name="cust_form" id="Cust_form" action="Cust_care" onsubmit="return Cust_check_field()">
//
</form>
我的Servlet是
package p1;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class Cust_care extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
try (PrintWriter out = response.getWriter()) {
out.println("<!DOCTYPE html>");
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet Cust_care</title>");
out.println("</head>");
out.println("<body>");
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection("jdbc:odbc:movie_pro","sa",".");
String cname=request.getParameter("c_name");
st.executeUpdate();
st.clearParameters();
//
out.println("</body>");
out.println("</html>");
}
catch(Exception e){}
}
這是我的web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web- app_2_5.xsd">

我得到任何錯誤HTTP狀態404，指出所請求的資源不可用
**或者我得到錯誤HTTP狀態500 **指出java.servlet.ServletException ：包裝找不到servlet的p1.cust_care
如果有人解決方案告知
