我可以在component.jsp中使用方法吗？

我正试图根据Adobe网站上的一篇文章编写一个简单的服务层界面（代码头中显示的链接供参考）。当我尝试基于模板/组件加载页面时，我得到一个错误：方法[methodname]对于类型[componentname]\u jsp是未定义的。我尝试过使用更简单的单行方法，使用public和no-access修饰符，使用不同的签名和返回类型，将方法移动到调用代码上方，并且总是得到相同的结果。如果我注释掉方法名，只将代码作为花括号括起来的块包含进来，那么它就可以编译了。这在CQ/AEM v5.6.1中是不可能的，还是我做错了什么

整个代码和异常如下所示（为了简单起见，注释掉了我的各种实验版本，并省略了原始的getPath（…）方法）。提前感谢您抽出时间
