【问题描述】：
首先是积极的部分： 我正在尝试使用 OpenCMIS 连接到 Alfresco，这在直接运行 Java 代码时有效:)
现在是负面的： 但是，当尝试从 WSO2 Carbon 运行 Java 代码时，似乎存在类加载器问题，并且加载了错误的 Authenticator 类。
我目前使用的是OpenCMIS 0.10.0 版本，尽管我也尝试过使用 0.11.0 和 0.12.0（最新）版本。
这是 ws02carbon.log 中的错误：
ERROR - Authentication provider does not implement AuthenticationProvider! {org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver}

这是代码：
public class CmisTestClient {
public static final String ALFRESCO_ATOMPUB_URL = "http://cmis.alfresco.com/cmisatom";
private static final String ALFRESCO_USER = "admin";
private static final String ALFRESCO_PASSWORD = "admin";
public static void main(String[] args) {
test();
}
public static void test() {
Map<String, String> parameters = new HashMap<String, String>();
SessionFactory sessionFactory = SessionFactoryImpl.newInstance();
// User credentials.
parameters.put(SessionParameter.USER, ALFRESCO_USER);
parameters.put(SessionParameter.PASSWORD, ALFRESCO_PASSWORD);
// AtomPub Connection settings...
parameters.put(SessionParameter.ATOMPUB_URL, ALFRESCO_ATOMPUB_URL);
parameters.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());
//parameters.put(SessionParameter.AUTHENTICATION_PROVIDER_CLASS, CmisBindingFactory.STANDARD_AUTHENTICATION_PROVIDER); // = the default
parameters.put(SessionParameter.AUTH_HTTP_BASIC, "true" );
parameters.put(SessionParameter.COOKIES, "true" );
// Alfresco only provides ONE repository.
Repository repository = sessionFactory.getRepositories(parameters).get(0);
Session session = repository.createSession();
}
}
我真的迷失了如何解决它，我已经尝试过（包括重新启动网络服务器）：
- 将 OpenCMIS jar 移动到： -[WSO2 碳首页]\5.2.1\lib -[WSO2 Carbon Home]\5.2.1\repository\lib -[WSO2 Carbon Home]\5.2.1\repository\components\lib -[WSO2 Carbon Home]\5.2.1\repository\components\extensions
- 直接在 .aar 文件中包含 OpenCMIS jar，EnableChildFirstClassLoading=true（也尝试使用 false）
请帮忙！这不是第一次在 WSO2 Carbon 中使用第三方库时出现问题，我想了解我犯了什么错误:)
