Is it possible to use Java webstart execute .exe or dll?
提问by Roy Chan
I know java webstart is running under a secure sandbox. Is it possible to include a .dll/.exe in the jar (or have the webstart download it to the local machine) and then execute it (using Runtime.exec or process,etc)
我知道 java webstart 正在安全沙箱下运行。是否可以在 jar 中包含 .dll/.exe（或让 webstart 将其下载到本地机器）然后执行它（使用 Runtime.exec 或 process 等）
Please Advise. Any suggestion/comment is welcome!
请指教。欢迎任何建议/评论！

Yes. You have to wrap the .dllin a .jarfile, and reference it in your .jnlpfile using <nativelib>
是的。您必须将其包装.dll在一个.jar文件中，并.jnlp使用<nativelib>
See herefor a more detailed description.
有关更详细的说明，请参见此处。
If you want to run an executable, then your best bet is to package it up in your .jaras a resource, explode it to (say) a temporary directory, and then run it using the normal Process/Runtime mechanism.
如果你想运行一个可执行文件，那么你最好的办法是将它打包在你.jar的资源中，将它分解到（比如）一个临时目录，然后使用正常的进程/运行时机制运行它。

Yes, as long as the user grants your application privileges (via the dialog that pops up), then Java webstart will have access to the file-system, and will have permission to use Runtime.exec.
是的，只要用户授予您的应用程序权限（通过弹出的对话框），那么 Java webstart 将有权访问文件系统，并有权使用 Runtime.exec。
