java - 基于 OIM 自定义 ICF 的连接器抛出运行时异常

Question

我创建了一个基于 ICF 的平面文件连接器，它使用 REST Web 服务从文件中读取/写入数据。我使用 jersey 实现 1.6 来编写 Web 服务和将调用该 Web 服务的 java 客户端。

我正在使用独立的java代码来测试CRUD功能。它在我初始化 Jersey 客户端的第一行给出了异常。

Client flatFileRestClient = Client.create();

我知道该错误是因为连接器服务器无法识别 Jersey 实现 jar。因此，根据 ICF 连接器的文档，我已将 Jersey bundle 放入 连接器服务器/lib 文件夹。我已重新启动连接器服务器并调用创建操作，但问题仍然存在。

我还在ConnectorServer.bat中添加了自定义jar的类路径文件位于 CONNECTOR_SERVER_HOME/bin 中。但问题仍然存在。

请找到 Eclipse 控制台上抛出的异常的完整堆栈跟踪:

问题是由于我正在使用的 REST API jar 造成的。我已经反编译了 jersey-bundle-1.6.jar 并发现该 jar 中不存在 javax.ws.rs.ext.Providers.class 。所以我下载了Jersey-bundler-1.16.jar的Java 6编译版本
