Java EE应用程序客户端容器 [英] Java EE Application client container
问题描述
Java EE服务器有3种类型的容器
There are 3 types of containers for a Java EE server
-
EJB容器
EJB container
Web容器
我找到了定义的应用程序客户端容器;
Application client container for which I found a definition saying;
管理应用程序客户端组件的执行。客户端
容器在客户端计算机上运行。
Manages the execution of application client components. The client container runs on client machine.
但我不明白Java EE容器如何驻留在客户端机器与在服务器上运行的EJB和Web容器形成对比吗？
But I don't understand how a Java EE container can reside in a client machine in contrast to the EJB and Web container that both run on a server?
有人能举例说明应用程序客户端组件的真正含义吗？
Can someone give me a example of what is really meant by application client components?
推荐答案
应用程序客户端容器只不过是应用程序客户端的组，例如EJB客户端，以及所需的库和Java虚拟机（JVM）。
Application client container is nothing but the group of you application client e.g. EJB Client, along with required libraries and the Java Virtual Machine(JVM).
为了更好地理解，请以EJB为例。您在应用程序服务器（EJB容器）上开发和部署EJB。现在，您可以使用在JVM上运行的简单JAVA客户端程序，将EJB客户端JAR与依赖JAR（如果有）一起分发，这些JAR可用于访问已部署的EJB bean。此客户端执行环境称为应用程序客户端容器。
To better understand, take example of EJB. You develop and deploy your EJB on your application server(EJB Container). Now you can distribute your EJB client JAR along with dependent JARs(if any) which can be used to access your deployed EJB bean using a simple JAVA client program running on a JVM. This client execution environment is termed as Application client container.
