Java + JSF - 在 bean 中构造 array/list 方法时出错，结合了 2 个参数
Java + JSF - Error in constructing array/list method in beans, with 2 parameters combined
大家晚安。我是 Java 的初学者，非常基础（我还在学习这门语言）。我正在构建一个针对汽车修理厂的应用程序；它必须管理车辆维护数据。我在最开始，从项目的一小部分开始试验，逐渐扩展和学习。我正在使用我在大学学到的旧 JDBC（我仍然必须了解 JPA + Hibernate，仍然很原始）。我将 Eclipse 2020 与 Maven、Java 8、JSF 2.2、BD MySql 和前面的 Primefaces 一起使用。
改编另一个项目的一部分，我在 Java 课程中学习过，该项目运行良好，在成功填充数据 Table 后使用“select * 来自 ORDSERV”语句一个正常工作的 prepareStatement，从数据库中提取所有记录，我想尝试使用 2 个标准交叉同一个数组，服务订单号 + 服务类别（“select * 来自 ORDSERV，其中 OSCTRL_NR_OS = ? AND CATEG_CD_CATEG =?") 在持久层和测试中一切正常，但在 Bean 中.. 事情变得疯狂了！
该项目没有运行。 Eclipse在页面上指出错误说我正在调用的方法不能被调用，因为它没有被标识为一个bean成员！ （“searchOS 无法解析为 osb 的成员”）。
有人可以给我一盏灯吗？？代码和错误堆栈如下。
我的母语是葡萄牙语，来自巴西。代码自然是用这种语言写的。
持久层：

这里主要是Bean（控制层），这是中心问题。方法getlistaTodasOS()正常工作，问题是我需要做什么来更正方法getpesquisaOS .

提前致谢！
ServicoBean class 有方法 getpesquisaOS() 和 getlistaNrsOS()。
应该是：
getPesquisaOS()
getListaNrsOS().
