摘要: 编译的时候提示软件包 javax.servlet.http 不存在，不明白，刚开始学MVC

编译的时候提示
ShowAction.java:5: 软件包 javax.servlet.http 不存在
import javax.servlet.http.HttpServletRequest;

以下是源代码
package beans;
import java.lang.reflect.InvocationTargetException;
import java.util.Locale;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.*;
import org.apache.struts.util.*;

public final class ShowAction extends Action
{
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
Locale locale = getLocale(request);
MessageResources messages = getResources(request);
HttpSession session = request.getSession();
GetParameterForm userform = (GetParameterForm) form;
if(userform.getValu().equals("success")) {
return(mapping.findForward("success"));
}
else {
System.out.println(userform.getValu());
return(mapping.findForward("fail"));
}
}
}
