index22.jsp只能導入一個類型。 com.journaldev.model.Employee解析爲一個包
<%@ page import="java.util.List" %>
<%@ page import="com.journaldev.model.Employee" %>
<%@ page import="com.journaldev.model.Person" %>
<%@ page import="com.journaldev.model.Address" %>
，當我訪問index22.jsp在瀏覽器收到以下錯誤：

我也包括一些JSTL罐和使用Tomcat7v
javax.servlet.jsp.jstl-1.2.1.jar
taglibs-standard-compat-1.2.5.jar
taglibs-standard-impl-1.2.5.jar
taglibs-standard-jstlel-1.2.5.jar
taglibs-standard-spec-1.2.5.jar
我想這個錯誤，因爲JSTL我已經包括但未經確認。 關於我得到的錯誤的任何想法？
Employee.java
package com.journaldev.model;
public class Employee implements Person {
private String name;
private int id;
private Address address;
public Employee() {
}
@Override
public String getName() {
return this.name;
}
@Override
public void setName(String nm) {
this.name = nm;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public Address getAddress() {
return address;
}
public void setAddress(Address address) {
this.address = address;
}
@Override
public String toString(){
return "ID="+id+",Name="+name+",Address="+address;
}
}
你能張貼'com.journaldev.model.Employee'完整的代碼？它也是一個包或類？ –
@Amit包含Employee.java –
你的課程看起來不錯。確保Employee.class部署在目錄** com/journaldev/model **下，而不是** com/journaldev/model/Employee ** –
