JNLP

The JNLP is an XML file that provides the basic elements and descriptions for your application .

JNLP是一个为应用程序提供基本的元素和描述的XML文件。

The following observations about the example JNLP file may assist you in creating your own files

接下来对JNLP文件的示例的评述也许在您创建自己的文件时对您有所帮助

For more information about the various elements and format of a JNLP file , refer to Resources .

更多有关JNLP文件的各种元素和格式的信息，请参考下面的参考资料。

Supporting download protocols as defined in the JNLP file

支持JNLP文件中定义的下载协议

Note that the only resources that a client may download are JAR files , images , and JNLP files .

注意客户机可以下载的资源仅为JAR文件、图像和JNLP文件。

This information is derived directly from the application 's JNLP file ( more on JNLP in a moment ) .

这条信息是直接从该应用程序的JNLP文件（稍后有更多关于JNLP的介绍）派生的。

Additionally , a Web server is needed and must be configured correctly to interpret all JNLP and MIME tags .

另外，需要Web服务器，而且Web服务器必须正确的配置来解释所有的JNLP和MIME标记。

As mentioned previously , the security attributes defined in the JNLP file determine the level of security that an application may have when launched via Java Web Start .

如前面提到的，在JNLP文件中定义的security属性决定了当应用程序通过JavaWebStart启动时所能有的安全性级别。

Whenever a user accesses a Java Network Launching Protocol ( JNLP ) file , the application is automatically downloaded to the user 's workstation and starts running .

每当用户访问Java网络启动协议（JavaNetworkLaunchingProtocol，JNLP）文件时，都自动将该应用程序下载到用户的工作站，然后该应用程序开始运行。

Making an application ready for Web Start is rather easy , all that is needed is a Jar containing all the files and a JNLP ( Java Network Launching Protocol ) description file .

使用WebStart部署应用相当简单，所需要的仅仅是一个包含所有文件和JNLP（JavaNetworkLaunchingProtocol）描述文件的jar包。

Various classes in the JNLP API library allow developers to use a system 's resources in an untrusted environment , assigning the user the responsibility to decide if the operation should be permitted .

JNLPAPI库中的很多的类允许开发者在不可靠的环境使用系统的资源，由用户来负责决定操作是否是允许的。

To provide a more convenient and efficient packaging scheme for the JNLP file and the JAR files associated with an application , Java Web Start enables the distribution of Web Archive ( WAR ) files .

为与应用程序相关的JNLP文件和JAR文件提供更加方便有效的打包方案，JavaWebStart使Web压缩文件（WAR）的分发成为可能。

Therefore , when editing a JNLP file , the final file should be converted using the native2ascii tool that is provided with the JDK to ensure a proper encoding of the file .

所以，当编辑JNLP文件时，最终文件要用与JDK一起提供的native2ascii工具转换来确保文件的编码正确。

The resource tags allow for the JNLP file to specify which JAR files the application uses as well as how to download the JAR files ; that is , either eagerly or lazily .

resource标记考虑到JNLP文件指定应用程序使用哪些JAR文件和如何下载JAR文件；即，是急切的还是不紧不慢的。
