【英文标题】：IBM Worklight 6.0 - Adapter authentication failure: "The server was unable to process the request from application"

【问题描述】：

环境配置：

Windows Server 2008 R2 企业版 WebSphere 应用服务器 v7 Worklight 服务器 v6 Derby 数据库（默认通过 Worklight 安装管理器安装）

在我的 Worklight 生产服务器上部署我的应用程序和适配器后，当我使用 Worklight Console 的 MBS（iPad 环境）测试我的应用程序时，我收到以下错误：

getNewsFeed_CallbackFailure 响应:: "status":500,"invocationContext":null,"errorCode":"UNEXPECTED_ERROR","errorMsg":"The 服务器无法处理来自应用程序的请求。请 请稍后再试。”

当我的 DB2Adapter 的过程 newsFeed 失败时调用 getNewFeed_CallbackFailure。

我的 Websphere SystemOut.log 中有这个错误：

日志文件的前 3 行来自我的自定义身份验证登录模块：

            ***Generic custom authentication code from worklight sample***

public class CustomAuthenticationModule implements WorkLightAuthenticator
    private static final Logger logger = Logger.getLogger(CustomAuthenticationModule.class.getName());

    private Map<String, Object> authenticationData = null;

    public void init(Map<String, String> options) throws MissingConfigurationOptionException 
        System.out.println("CustomAuthenticationModule");
        logger.info("CustomAuthenticationModule initialized");
    
     ............

---

                  ***My custom authentication code***

public class CustomLoginModule implements WorkLightAuthLoginModule 

    private String USERNAME;
    private String PASSWORD;

    public void init(Map<String, String> options) throws MissingConfigurationOptionException 
        System.out.println("init CustomLogi nModule");
    
        ............

除此之外，我在 Worklight 开发服务器上没有任何错误...适配器的工作原理非常棒。

【问题讨论】：

请尝试使用 6.0.0.1 或 6.1.0；我相信这不应该再发生了。

【参考方案1】：

这种类型的错误在 6.0.0.0 之后早就修复了；所以我建议至少升级到 Worklight 6.0.0.2，如果不升级到 6.1.0.1。

没有可采用的本地解决方法。 如果您是 IBM 客户或业务合作伙伴，您可以从 IBM Fix Central 下载上述版本。
