使用Java web start通过文件名在命令行启动应用程序
我可以使用 Java web start 在命令行上通过 jdk 6 & 的 url 启动我的 Swing GUI 应用程序。 Windows XP: javaws http://localhost:7001/webstart/myapp/launch.jnlp
使用方法Java web start 通过文件名在命令行上启动我的 Swing GUI 应用程序?

I can use Java web start to start my Swing GUI application on the command line by the url with jdk 6 & Windows XP:
javaws http://localhost:7001/webstart/myapp/launch.jnlp
How to use Java web start to start my Swing GUI application on the command line by the file name?

尝试使用代码库值..
Try a codebase value of..
看来您的 JNLP 文件应该与 一起使用JNLPDownloadServlet。它会将
$$name
和$$codebase
占位符替换为基于应用程序当前运行的服务器的当前值。 (顺便说一句,您还可以使用$$server
来引用当前服务器)如果您从磁盘本地运行它,则可以通过在命令行上设置来覆盖
codebase
作为参数-codebase
。正确的值为file:.
。您的问题是$$name
占位符未被替换,并且它尝试下载
,结果为file:.$$name
并且由于不存在这样的文件,因此失败。您可以在本地运行时完全省略
标记中的href="$$name"
属性,也可以手动将其更改为 jnlp 文件名,例如
。另请记住,如果您想使用存储在磁盘上的某些本地 jar 并且希望通过绝对路径引用它,您应该使用此格式
(正斜杠)。一切顺利。
It seems your JNLP file should be used together with the JNLPDownloadServlet. It replaces the
$$name
and$$codebase
palceholders with the current values based on the server where you application currently runs. (Btw. you can also use$$server
to refer the current server)If you run it locally from disk, you can overwrite the
codebase
by setting it on the command line as parameter-codebase
. The right value isfile:.
. You problem is that the$$name
placeholder is not replaced and it tries do download the<jnlp ... href="$$name">
which results tofile:.$$name
and since no such file exists it fails.You can either completely omitt the
href="$$name"
attribute in the<jnlp />
tag when running locally or manually change it to the jnlp file name e.g.<jnlp ... href="myApp.jnlp" />
.Also remeber if you want to use some local jar stored on you disk and you want to refer it via absolute path you should use this format
<jar href="file:c:/myJars/myJar.jar">
(forward slashes).All the best.
