java - 公共(public)静态类的 YAJSW 错误

Question

我有一个 java 应用程序，我正在尝试开始使用 YAJSW。这只是一个简单的“Hello World”应用程序，我按照此处的说明进行操作:http://yajsw.sourceforge.net/#mozTocId527639

我已完成以下操作:

• 将我的项目从 Eclipse 导出为可运行的 JAR 文件。

• 我运行了 genconfig - 没有问题

• 我编辑了wrapper.conf并添加了jar文件的位置

• 运行 runConsole.bat，我收到此错误:

  java.lang.IllegalAccessException: class org.rzo.yajsw.app.WrapperJVMMain can not access a member of class xxxx with modifiers "public static"

它引用的类是主类，必须是public static。我被困住了!有人可以给点建议吗？

我遇到了同样的问题(在 Java 1.6.0_30-b12、Win XP Pro v 2002 SP3 上运行 yajsw-stable-11.0):

在我的例子中，包含静态公共(public) main 方法的类没有声明为公共(public)的，因此它是默认的包私有(private)的。

class Proxy {
...
    public static void main(String args[]) throws IOException{
        ...
        }
}

包私有(private)类的公共(public)方法对于属于不同包的类不可见，所以这就是我的情况的问题。例如，参见https://stackoverflow.com/questions/5260467/public-methods-in-package-private-classes .

public class Proxy {
...
    public static void main(String args[]) throws IOException{
        ...
        }
}

如上所述将类声明为 public 解决了我的问题。也许您可以发布有关整个问题的更多详细信息，然后有人会发布解决方案。问候-GF
