What Is JNLP All About?
JNLP is an XML-based technology for launching Java executables over the Web. Just imagine that you could specify the classpath resources in your application (images, JAR files, properties, files, etc.), scattered over the Web and giving their URLs, instead of relying on the local file system as normal Java applications do. This feature would give you the capability of deploying your application automatically (that is, installing needed application files and launching them properly) just by declaring where your files are on the Web. Then imagine adding capabilities, such as distinguishing between versions of the same file depending on some local parameter, and so on. That would be great. Imagine you could say “If the locale is ‘Chinese,’ use the input framework extension and those JAR files there.” Or “If the client platform is ‘Windows’, launch this installer here before running the application.” That would save a lot of coding effort (and such installation problems are very common), a
