Question

我正面临在Apache Chemistry OpenCmis 0.10.0中执行Session getObject的NullPointerException。我也在使用Alfresco OpenCmis扩展0.6。

这是使用的代码：

OperationContext context = getSessionManager().getSession().createOperationContext();
context.setCacheEnabled(true);
context.setIncludeRelationships(IncludeRelationships.NONE);
CmisObject object = getSessionManager().getSession().getObject(uuid, context);

这是堆栈跟踪：

    at org.apache.chemistry.opencmis.client.runtime.SessionImpl.getObject(SessionImpl.java:414)

似乎null指针发生在CMIS缓存中，你见过这个错误吗？我在论坛上搜索过，但我还没有看到这个错误。

谢谢！

使用logidoc社区版时我遇到了类似的错误。由于我从logidoc网站获得的服务URL发生错误。如果你的用户名和密码没问题，那么罪魁祸首可能就是服务网址。
