servlet不能运行，大家帮忙看看

[zrhk]

web.xml里的配置：
<servlet>
<servlet-name>
techsupport
</servlet-name>
<servlet-class>
techsupport
</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>
techsupport
</servlet-name>
<url-pattern>
/techsupport
</url-pattern>
</servlet-mapping>


classes目录中techsupport.java
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import sun.net.smtp.SmtpClient;
import com.wrox.util.*;

public class techsupport extends HttpServlet
{
String message,msgFrom ,msgTo,msgSubject;
public void doPost(HttpServletRequest req, HttpServletResponse res) throws IOException,ServletException
{
res.setContentType("text/html");
PrintWriter out=res.getWriter();
getParameters(req);

if(!sendMail())
{
res.sendError(res.SC_INTERNAL_SERVER_ERROR,
"An error occured while attemption to access the main srver");
return;
}
HTML h =new HTML("XYZ corporation IT D epartment");
h.add(HTML.HEADING,"Your requet has been submitted",false);
out.println(h.getPage());
out.close();
}

private void getParameters(HttpServletRequest req)throws ServletException,IOException
{
StringBuffer tempStringBuffer=new StringBuffer(1024);
msgSubject="Tech Support Request";
msgTo="[e-mail]";
msgFrom=req.getParameter("txtEmail");

tempStringBuffer.append("From: ");
tempStringBuffer.append(req.getParameter("txtFirst"));
tempStringBuffer.append(" ");
tempStringBuffer.append(req.getParameter("txtLast"));
tempStringBuffer.append("\n");
tempStringBuffer.append("Phone: ");
tempStringBuffer.append(req.getParameter("txtPhone"));
tempStringBuffer.append("\n");
tempStringBuffer.append("Email: ");
tempStringBuffer.append(req.getParameter("txtEmail"));
tempStringBuffer.append("\n\n");
tempStringBuffer.append("Software: ");
tempStringBuffer.append(req.getParameter("ddlb_software"));
tempStringBuffer.append("\n");
tempStringBuffer.append("OS: ");
tempStringBuffer.append(req.getParameter("ddlb_os"));
tempStringBuffer.append("\n");
tempStringBuffer.append("Problem: ");
tempStringBuffer.append(req.getParameter("txtProblem"));
tempStringBuffer.append("\n");
message=tempStringBuffer.toString();
}
private boolean sendMail()
{
PrintStream out;
SmtpClient send;
try
{
send=new SmtpClient("21cn.com");
send.from(msgFrom);
send.to(msgTo);
out=send.startMessage();
out.println("From: "+msgFrom);
out.println("To: "+msgTo);
out.println("Subject: "+msgSubject);
out.println("\n--------------------------\n");
out.println(message);
out.println("\r\n");
out.println("\n--------------------------\n");
out.flush();
out.close();
send.closeServer();
}
catch(IOException e)
{
log("Error occurred while sending mail",e);
return false;
}
return true;
}
}
编译完全通过了


可是在运行时
http://localhost:8080/techsupport时
出现如下错误

那当然了，你的servlet当中提供的方法是doPost方法，而不是doGet啊，你把那个doPost改成doGet试试，或是把另一页面form中的方法改成method="post"

[wjmmml]

你的servlet里面没有doGe方法所以，不能够运行，你可以吧你的form表单的method=get 改成method=post就可以了，

[sunni]

doGet() not doPost()

[littlecong]

把doPost改为service

[zrhk]

嘻嘻，我明白错在哪了
我在
<form action="http://127.0.0.1:8080/techsupport" method="post">
.....
</form>
应该通过html传送，执行doPost()方法
