How to create Struts 2 project in Eclipse Galileo?
提问by Anand
I want to create a struts 2 project in eclipse. I have downloaded the latest struts distribution. But things always become confusing when i try to create a struts project in ECLIPSE. Whenever I create a dynamic web project and add struts libraries to that project, some error or the other pops up.
我想在 Eclipse 中创建一个 struts 2 项目。我已经下载了最新的 struts 发行版。但是当我尝试在 ECLIPSE 中创建一个 struts 项目时，事情总是变得混乱。每当我创建一个动态 Web 项目并将 struts 库添加到该项目时，就会出现一些错误或其他错误。
How do I properly setup an eclipse Struts 2 project ?
如何正确设置 Eclipse Struts 2 项目？
To get a simple Hello world page, I did:
为了得到一个简单的 Hello world 页面，我做了：
- created a dynamic web project (procollab)
- added struts 2 jars inside WEB-INF/lib
- added the same libraries inside project build path
- set the output folder for the src in WEB-INF/classes
- created a filter in web.xml to send all requests to org.apache.struts2.dispatcher.FilterDispatcher
- created a struts.xml in src
- 创建了一个动态网络项目（procollab）
- 在 WEB-INF/lib 中添加了 struts 2 jars
- 在项目构建路径中添加了相同的库
- 在 WEB-INF/classes 中为 src 设置输出文件夹
- 在 web.xml 中创建了一个过滤器，将所有请求发送到 org.apache.struts2.dispatcher.FilterDispatcher
- 在 src 中创建了一个 struts.xml
Errors I get:
我得到的错误：
Http 404. I get this for any URL, for example http://localhost:8080or http://localhost:8080/procollab
Http 404。我为任何 URL 获取此信息，例如 http://localhost:8080或http://localhost:8080/procollab
I have added the project procollab in tomcat server list also in eclipse. but when I access any static resource directly, I get the page. I have the helloworld.jsp in webcontent folder, and when I go to http:localhost:8080/procollab/helloworld.jsp, I get the page correctly.
我也在 eclipse 中在 tomcat 服务器列表中添加了项目 procollab。但是当我直接访问任何静态资源时，我得到了页面。我在 webcontent 文件夹中有 helloworld.jsp，当我转到 http:localhost:8080/procollab/helloworld.jsp 时，我得到了正确的页面。
Have I set up my environment correctly ? Please help
我是否正确设置了环境？请帮忙
my struts.xml file in WEB-INF/classes
我的 WEB-INF/classes 中的 struts.xml 文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC

Http 404. I get this for any URL, for example http://localhost:8080or http://localhost:8080/procollab
Http 404。我为任何 URL 获取此信息，例如http://localhost:8080或http://localhost:8080/procollab
So that's the only problem? Well, a 404 just means that there's no resource on the requested URL. Page Not Found. Simple as that. You need to provide/specify the resource yourself, Eclipse won't do that for you or so. It's the code which you have full in control yourself.
所以这是唯一的问题吗？好吧，404 只是意味着请求的 URL 上没有资源。找不到网页。就那么简单。您需要自己提供/指定资源，Eclipse 不会为您做这些。这是您可以完全控制自己的代码。
I am not sure what you expect to see at http://localhost:8080, so I'll ignore this part. As to the 404 on http://localhost:8080/procollab, you just need to define a <welcome-file>in the web.xmland ensure that this is available by either (in)directly by a servlet or filter mapping, or a physical file in WebContent. That's all.
我不确定您希望在http://localhost:8080看到什么，所以我将忽略这部分。至于404上的http：//本地主机：8080 / procollab，你只需要定义一个<welcome-file>在web.xml直接通过servlet或过滤器映射，或者在一个物理文件，并确保这是可通过（中）WebContent。就这样。
If you want to make helloworld.jspthe default landing page, you'll need to add the following to the web.xml:
如果要制作helloworld.jsp默认登录页面，则需要将以下内容添加到web.xml：
<welcome-file-list>
<welcome-file>/helloworld.jsp</welcome-file>
</welcome-file-list>
Update: as per the posted struts config, you thus expect that http://localhost:8080/procollab/SayHello.actionis been executed when you access http://localhost:8080/procollab. In this case, you need to configure the <welcome-file>as follows:
更新：根据发布的 struts 配置，您因此期望在访问http://localhost:8080/procollab时执行http://localhost:8080/procollab/SayHello.action。在这种情况下，您需要进行如下配置：<welcome-file>
<welcome-file-list>
<welcome-file>/SayHello.action</welcome-file>
</welcome-file-list>
