initialcontext

You simply create an InitialContext ( with no parameters ) and start using it .

您只需创建InitialContext（不含参数）就可开始使用。

The middle section contains the events that result from the InitialContext . lookup () method .

中间部分包含InitialContext.lookup（）方法中产生的事件。

Once you 've created the properties , you 're ready to create the InitialContext instance and use it .

创建好属性之后，就可以创建并使用InitialContext实例了。

Then , the code gets the reference to the JMS topic using the same lookup method on the InitialContext object .

然后，代码使用InitialContext对象上相同的查询方法（lookup）来获取JMS主题的引用。

For the creation of the InitialContext object in the top section , there are no obvious differences between this scenario and the first one .

对于上方部分的InitialContext对象创建，此场景与前一个场景之间不存在明显的区别。

Instead of using the ActiveMQConnectionFactory concrete implementation , this Java code uses the InitialContext object to " look up " the specific connection factory implementation .

以上Java代码没有使用ActiveMQConnectionFactory的具体实现，而是使用了InitialContext对象来“查找（lookup）”指定的连接器工厂实现。

By default , the InitialContext factory is defined in jndi . properties , and the factory class has defaults for a server URL and a port number .

在默认情况下，InitialContext工厂是在jndi.properties中定义的，这个工厂类有默认的服务器URL和端口号默认值。

To make the connection through JNDI , you must use a number of Geronimo-specific properties to create the InitialContext instance , which is then used to perform lookups .

要通过JNDI进行连接，必须使用大量特定于Geronimo的属性来创建InitialContext实例，该实例用于执行查询。

This class , along with details of nameserver URL and port number , is used to generate the InitialContext class that you use to interact with the namespace .

这个类连同命名服务器URL和端口号的详细信息，用于生成与名称空间交互的InitialContext类。

While there are subclasses of InitialContext that are specific to directory operations , such as InitialDirContext , the generic class will do the job .

尽管有一些特定于目录操作的InitialContext子类（如InitialDirContext），但通用类将完成此任务。
