使用PDF文档将项目导出到Runnable JAR文件中

I have project that I created and it contains a help button that opens a .pdf file with my documentation. The code for the button is the following

我有我创建的项目,它包含一个帮助按钮,用我的文档打开.pdf文件。该按钮的代码如下

URL loc = Actions.class.getResource("Documentation/test.pdf");
            Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + loc);

When I run and execute my application using eclipse and click on the button it opens the document fine in adobe reader. After I export my project into a Runnable JAR File via eclipse and click on the button it doesn't do anything. Is there something that I need to add in order to make this work?

当我使用eclipse运行并执行我的应用程序并单击按钮时,它会在adobe reader中打开文档。在我通过eclipse将项目导出到Runnable JAR文件并单击按钮后它没有做任何事情。为了使这项工作,我需要添加一些东西吗?

I just opened the jar file using 7zip and my test.pdf document does show up in there.

我刚刚使用7zip打开了jar文件,我的test.pdf文件确实显示在那里。

This may be because the pdf file is inside the jar and returned URL from method getResource can not be recognized by external program.

这可能是因为pdf文件位于jar内部,并且方法getResource返回的URL无法被外部程序识别。

You can do a print of "loc" to see what the URL looks like when it's in the jar file.

您可以打印“loc”以查看URL文件中的URL。

The default behavior and intentions behind a jar file are for packaging of files (Java) into a compressed format. If you want to have an executable type jar then you need to include a manifest file that specifies your main Java class (the class that contains the main(). From here you can code the logic to launch your pdf's.

jar文件背后的默认行为和意图是将文件(Java)打包成压缩格式。如果你想拥有一个可执行类型jar,那么你需要包含一个清单文件来指定你的主Java类(包含main()的类。从这里你可以编写逻辑来启动你的pdf。
