Question

嗨，我有一个java swing应用程序，我想通过jnlp启动它，我配置了我的项目Web启动配置但是当我按下启动按钮时不起作用。你知道为什么吗？

这是错误

Answer 1

由于此错误，我们只能告诉您，由于parseInt上的String不是int，您的问题才会发生。要纠正这个问题，您有两种可能性：

添加try{}catch(NumberFormatException e){//show error}
断言您有parseInt;）

Answer 2

我有同样的问题 Netbeans 8.01，JDK 1.8u20，JRE项目，

运行选项：

'启用webstart'。

应用程序/ Webstart选项：

创建证书密钥库（提示：我使用'portecle'）
代码库：本地执行（预览显示：'file：/ C：/..../'）

项目创建的JNLP表示;

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<jnlp codebase="file:/C:/<snip>/dist/" href="launch.jnlp" spec="1.0+">
