我的 Java FX2 应用程序配置串行设备，作为部署的一部分，它必须安装 Windows 设备驱动程序并将 native 库(RxTx 串行端口库)复制到 Java 目录中。
Java Web Start 可以处理吗？或者用户应该分阶段进行:手动安装驱动程序，然后复制库，然后通过 Web Start 安装应用程序。
更新: 下面的 MyApp.jar 是自签名的。我把dll放在项目名下。我在我的 jnlp 中为 dll 添加了这一行。我使用的是 Netbeans 7.3，因此放置了 VM args 行。 我的 jnlp 看起来像这样:
<resources>
<j2se version="1.6+" java-vm-args="-Djava.library.path=. " href="http://java.sun.com/products/autodl/j2se"/>
<jar href="MyApp.jar" size="216992" download="eager" />
<jar href="lib/RXTXcomm.jar" size="66493" download="eager" />
<nativelib href="rxtxSerial.dll" size="122880" download="eager" />
</resources>
<security>
<all-permissions/>
</security>
我可以在 Netbeans IDE 中运行该应用程序。但是，单击 jnlp，我得到弹出窗口“运行时错误”。它要求我单击以获取详细信息，但没有显示任何内容。 我在 Java 控制面板的临时 Internet 文件中删除了较早的 jnlps。在 Java 控制台中我什么也看不到。
@AndrewThompson 我试过 Janela 检查 jnlp。有用的工具!我看到 dll 没有进入 dist 文件夹。 jnlp 由 NB 7.3 生成。有什么方法可以让它放入 nativelib 行吗？我每次都必须手动完成。 `

我把dll放到一个jar里，然后添加
System.loadLibrary("./rxtxSerial");
那也失败了。
最佳答案
只要您留在沙箱(未签名的应用程序)中，您将无法访问本地文件系统。关于设备驱动程序安装，我想签名的应用程序也可以安装，但它可能会触发 Windows 确认。
