Question

我是Struts2的初学者，并且已经成功实现了简单的示例。

我对瓷砖有意见

我从这个网站推荐 http://www.dzone.com/tutorials/java/struts-2/struts-2-example/struts-2-tiles-example-1.html

我的文件和上面提到的那个网站上的完全一样

我使用的是：Netbeans ide 7.3、struts 2、glassfish 3.1.2.2（注意：教程网站上的可下载文件在EclipseIDE中运行，我需要在Netbeans中添加什么额外内容）

以下是我在GlassFish中发现的错误:

**HTTP状态404**

类型：状态报告

描述:请求的资源()不可用。

尝试了两种库样式，即：netbeans插件额外平铺和所有jar

帮助:)

Answer 1

我解决了。该错误与netbeans struts插件有关，该插件没有磁贴供应。在粘贴无效的代码后，我已经移除了tiles插件。

现在我做的是:1 .创建一个项目。

2.添加了NetBeans的struts2框架（否则Struts.xml未添加到配置文件夹中，并且在任何其他地方都不起作用:(）

3.删除库

4.清洁和建造

5 .手动添加JAR文件

现在工作：）非常感谢您的建议：）
