GWT：如何使用来自单独模块的bean？

Question

我正在开发一个包含独立模块的项目。后端 管理员，客户端 用户和 core 用于在 backend 和 client 之间共享 DAO 层。
backend 模块使用 GWT，client 使用 Spring MVC。在 backend 模块，core 模块被包含在 deployment assembly. My server side , DAOs are injected by Spring.
All beans(POJOs) created in core module. My problem is I would like to use these beans from core module in my gwt project (backend module) or when using RPC calls.
I tried as answers of How can share bean from external library to GWT client? 问题中，但还没有满足。我遇到以下错误

No source code is available for type com.mycom.core.business.bean.TestBean; [ERROR] Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly

这是我努力的代码...

TestBean.java

public class TestBean {
private int id;

public final int getId() {
    return id;
}

public final void setId(int id) {
    this.id = id;
}
}

beans.gwt.xml

<?xml version="1.0" encoding="UTF-8"?>
<module>
   <inherits name='com.google.gwt.user.User'/>
   <source path="com.mycom.core.business.bean.TestBean"/>
</module>

继承我的App.gwt.xml中的beans.gwt.xml为<inherits name='com.mycom.backend.beans'/>。我错过了什么？

Edit: Add sample project file

现在我创建并上传了示例模块。您可以从 google-drive URL 下载它。此存档文件包含 backend 和 core 模块。

core 模块是从 Eclipse IDE.
backend 模块由 gwt-ecliplse 插件创建 （2.7 gwt 版本并包含生成的代码） 并添加Dynamic Web Module 2.5 项目面.

最后，我使用 GWT-Eclipse 插件 构建并运行，您可以查看

Answer 1

GWT 编译过程应该可以访问核心模块的源路径。确保将其添加到类路径或源查找路径中。

Answer 2

beans 的模块文件应该在 core folder/library 中。尝试将其移动到 core/src/com/mycom/ 并在 beans.gwt.xml:

中相应地修改源路径

<source path="core"/>

记住，是相对于模块文件的。

然后修改App.gwt.xml中的条目：

<inherits name='com.mycom.beans'/>

我不熟悉部署程序集，但请确保 beans.gwt.xml 存在于生成的库 jar 中（或与源代码一起复制）。
