我们的示例MBean代码和WebSphereXMLMBean描述符文件被存储在位于 /build/newmbean/newmbean.jar 的 JAR 文件中。
Our example MBean code and WebSphere XML MBean Descriptor file are stored in the JAR file located at /build/newmbean/newmbean.jar .
需要使用Portlet的部署描述符提供一些必须的设置，而且，由于这些项也是由Portlet开发人员提供的，因此被认为是自定义代码。
Some required Settings need to be provided with the portlet's deployment descriptor, and since these items are also supplied by a portlet developer, they are therefore considered custom code.
使用文件描述符读取在之前的功能函数中获得的字节，我使用以下代码。
To read the bytes using the file descriptor obtained in the previous function call, I use the following code. It reads the indicated number of bytes from the file parameter passed.
客户端部署描述符，在一个称为application-client.xml的文件中，包含对用于上述代码中JMS连接工厂和队列中JNDI名称的引用。
The client deployment descriptor, in a file called application-client.xml, contains references to the JNDI names of the JMS connection factory and queue that are used in the above code.
因为可以将对容器的请求放入到代码中，所以使得对部署描述符与代码进行同步的开销减到最小。
Since the request for the container can be put in the code, the overhead cost of synchronizing the deployment descriptor with the code is minimized.
您的代码获取它需要的图像描述符，然后将其添加到图像注册表，并使用键为每个图像描述符建立索引。
The idea is that your code obtains the image descriptors it needs and adds them to the image registry, indexing each one with a key.
