环境配置：
- Windows Server 2008 R2企业版
- WebSphere应用程序服务器v7
- Worklight Server v6
- Derby数据库（通过Worklight Installation Mananger进行默认安装）
在工作灯生产服务器上部署应用程序和适配器后，当我使用worklight Console的MBS（iPad环境）测试应用程序时，我会收到以下错误：
getNewsFeed_Callback失败响应：：｛"status"：500，"invocationContext"：null，"errorCode"："UNEXPECTED_ERROR"，"errorMsg"："服务器无法处理来自应用程序的请求。请请稍后再试。"｝
其中，当DB2Adapter的过程newsFeed失败时调用getNewFeed_CallbackFailure。
我在我的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。。。适配器的工作原理很有魅力。
这种类型的错误在6.0.0.0之后已经被长期修复；因此，如果不是升级到6.1.0.1，我建议至少升级到Worklight 6.0.0.2。
当地没有变通办法
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。
