JNLP 文件，全名為 Java Network Launching Protocol 文件, 我們需要 javaws 命令去執行它。
在 fedora 中 ，我們需要安裝 相應的 rpm 包，yum 倉庫中已經為我們準備好了相關的文件，我們只需要運行命令來安裝就行了。當然你也可以使用 編譯源碼安裝。

Javaws 命令 執行
➜ Downloads javaws SYNOPSIS javaws [-run-options] jnlp file javaws [-control-options] OPTIONS When specifying options, the name of the jnlp file can be after the command, the -jnlp option, an option with no arguments, or after an argument with an option that takes one argument. A html file that launches a jnlp can be specified after the -html option. The jnlp-file can either be a url or a local path. The JNLP file should only be specified once, whether as a main argument, after -jnlp or through an html file. Control options: -about - Shows a sample application.(No argument expected) -help - Prints out information about supported command and basic usage.(No argument expected) -license - Display the GPL license and exit.(No argument expected) -viewer - Shows the trusted certificate viewer.(No argument expected) -Xclearcache - Clean the JNLP application cache.(No argument expected) Run options: -allowredirect - Follows HTTP redirects.(No argument expected) -arg arg - Adds an application argument before launching.(Expected one or more arguments) -browser - Launch embeded browser. Use in great need only!(Expected one or more arguments) -headless - Disables download window, other UIs.(No argument expected) -html - Location of HTML file to launch (url or file). You can use parameter ALL or numbers (like 1 2 5) to select applets on page. However experimental, this switch should keep you still in safety.(Expected one or more arguments) -jnlp - Location of JNLP file to launch (url or file).(Exactly one argument expected) -nosecurity - Disables the secure runtime environment. You need also deployment.security.itw.ignorecertissues to workaround corrupted signatures(No argument expected) -noupdate - Disables checking for updates.(No argument expected) -param name=value - Adds an applet parameter before launching.(Expected one or more arguments) -property name=value - Sets a system property before launching.(Expected one or more arguments) -strict - Enables strict checking of JNLP file format.(No argument expected) -update seconds - Check for updates.(Exactly one argument expected) -verbose - Enable verbose output.(No argument expected) -version - Print the IcedTea-Web version and exit.(No argument expected) -Xignoreheaders - Skip jar header verification.(No argument expected) -xml - Uses a strict XML parser to parse the JNLP file.(No argument expected) -Xnofork - Do not create another JVM.(No argument expected) -Xoffline - Prevent ITW network connection. Only cache will be used. Application can still connect.(No argument expected) -Xtrustnone - Instead of asking user, will foretold all answers as no.(No argument expected)View Code
Javaws 命令 說明
NAME javaws - a Java Web Start client SYNOPSIS javaws [-run-options] jnlp file javaws [-control-options] DESCRIPTION javaws is an implementation of a JNLP client. It uses a JNLP (Java Network Launch Protocol) file to securely run a remote Java application or a Java applet. This implementation of javaws is from the IcedTea project and is based on the NetX project. A JNLP file is an xml file that describes how to securely run a remote Java application or a Java applet.
執行 jnlp 文件：
➜ Downloads javaws viewer.jnlp
同理，在 ubuntu 中，也可以使用 apt 等工具進行搜索安裝。
具體情況以實際執行為準。
