使用 Glassfish 上的应用程序客户端容器 (ACC) 为远程部署构建 ear

Question

对于 ACC，一个 JAR 是否依赖于另一个 JAR？文档对此并不十分清楚，至少so far as I've read。

我的理解是我需要从existing code 构建一个可以远程部署的 EAR。此 EAR 应包含现有客户端。所有代码：1.) 客户端，2.) EJB 模块和 3.) 远程接口在 localhost 上运行。我已将 EJB 部署到远程 Glassfish 服务器。

如何从Creating and Running an Application Client on the GlassFish Server 创建一个“ant-java-ee project”？我创建包的示例非常奇怪。 Netbeans 似乎没有“ant jar”选项，它以我熟悉的方式构建它。没有像 Netbeans 应用程序那样典型的 ant jar 目标； ant dist 结果：

dist:

另一方面，ant run 给出了很好的结果：

-run:
     [java] hello world

run:

这些 jar 没有按我的预期打包：

我不清楚这些 JAR 之间的关系。通常，Netbeans 将为 API 构建一个“lib”文件夹。在这种情况下，ACC 有一些魔力。目标是将此应用程序打包为 EAR，以便将其部署到远程 Glassfish 服务器。

Answer 1

选择 File > New Project 并在 Java EE 类别中选择 Enterprise Application Client

您需要远程接口，而不是客户端中的 ejb 代码

client 使用 rmi (socket) 与服务器通信并在服务器端运行 ejb

客户端容器被视为供应商的继子，大多数 soa 架构在两侧都有完整的 java ee 服务器，即 java ee web 应用程序是 java ee ejb/webservice 应用程序的客户端

我讨厌所有那些 netbeans 文件，我宁愿使用 maven，有时可能会更难，但你会在网络上获得更好的支持

对于远程调用，我会使用 jax-rs 或 jax-ws
