CMIS会话GetObject-Apache化学中的NullPointer

Question

我在Apache Chemical OpenCmis0.10.0中执行会话getObject时遇到了一个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);

java.lang.NullPointerException

谢了！

我在使用logidoc社区版本时也遇到了类似的错误。错误是由于我从logidoc网站获得的服务url而发生的。如果您的用户名和密码是正确的，那么罪魁祸首可能是服务URL。
