Question

一个JAR是否依赖另一个JAR？文档对此至关清楚，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。

如何创建＆＃34; ant-java-ee project＆＃34;来自Creating and Running an Application Client on the GlassFish Server？我创建的示例包非常奇怪。 Netbeans似乎没有一个＆＃34; ant jar＆＃34;选项，以熟悉的方式为我构建它。 Netbeans应用程序通常没有ant jar目标; ant dist导致：

dist:

另一方面，ant run给出了很好的结果：

-run:
     [java] hello world

run:

这些罐子没有包装我的预期：

我不清楚这些JAR之间的关系。通常Netbeans会构建一个＆＃34; lib＆＃34; API的文件夹。在这种情况下，ACC会有一些魔力。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。

选择文件＆gt;新项目并在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

客户端使用rmi（套接字）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步骤子项，大多数soa架构都有完整的Java ee服务器，即java ee web应用程序是java ee ejb / webservice app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，但你会在网上获得更好的支持

对于远程调用，我会使用jax-rs或jax-ws

使用Glassfish上的应用程序客户端容器（ACC）构建用于远程部署的耳机
