我想包含我的java应用程序，我将其保存为web浏览器中的jar文件。我已经尝试了JavaWebStart教程，并创建了JavaJNLP应用程序。我还遵循基于以下内容的教程：http://transvar.org/6112/WebStartAppInstruction.pdf
我已经尝试了所有的步骤，但在我下载Launch.jnlp并尝试启动它之后，会弹出"Unable to Launch the application"这样的错误。我单击"详细信息"按钮查看我做错了什么。
以下是错误(异常选项卡)：

我真的是Java JNLP的新手。希望在这里得到一些帮助。
根据链接的文档，您需要对其进行编辑以定位应用程序的代码库。即
<jnlp codebase="http://webpages.uncc.edu/~acenglis" href="launch.jnlp"/>
我看你没有完全遵循教程(尤其是编辑你的jnlp文件)
