java - Eclipse: use Struts Actions of imported Project

Question

I have 2 Dynamic Web Projects:

• cms
• Demo

Using Struts2 I want project Demo to use actions of the project CMS.

In Demo's "Java Build Path" configuration, in the "Project" tab I added the CMS project.

Now in the struts.xml of Demo I have

<action name="hello" class="cms.helloworld.action.HelloWorldAction" method="execute">

where the package cms.helloworld.action is a CMS project package.

Eclipse see it correctly, in fact with ctrl+right click on the class name it open me the correct Java file.

Now, in Demo's deployment assembly configuration I added the CMS project, so that also Tomcat can find the relative classes.

But when I run the project on tomcat server the log says:

Grave: Dispatcher initialization failed Unable to load configuration. - action

Caused by: Action class [cms.helloworld.action.HelloWorldAction] not found

It can't find the action on CMS project.

What am I doing wrong?

您应该将两个项目合并为一个，并struts.xml放入src. 据我所知，Eclipse 无法将另一个 Web 项目作为模块引用，即您必须WebContent在构建期间手动复制，这就是为什么您不应该引用其他 Web 项目并且主项目不是 Java EE 项目的原因。如果您决定开发一个，您还应该考虑到 Tomcat 服务器无法处理 Java EE 项目，为此您应该选择功能齐全的 Java EE 应用程序服务器。即使您只能选择一个 Web 模块。
