无法启动应用程序

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

只有这个错误，我们只能告诉您，您的问题是由于String上的parseInt而发生的，这不是int。要纠正此问题，您有两种可能性：

1. 添加try{}catch(NumberFormatException e){//show error}
2. 断言你有适当的东西进入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"以网络启动方式运行"。

应用程序/网络启动选项：

• 创建的证书密钥库（提示：我使用了"portecle"）
• 代码库：本地执行（预览显示："file：/C：/..../"）

该项目创建的JNLP说;
