What happened to the Business Objects knowledge base?

Hi,

The PDF document referred to by this article mentions some knowledge base articles on the Business Objects support site:

http://scn.sap.com/docs/DOC-21828

For example:

c2017726 - Error: "Failed to retrieve data from database" passing parameters to a JavaBean

c2011506 - Configuring Crystal Reports 10 to use Java Bean classes as data sources

c2011653 - Limitations when using crdb_javabeans.dll to report on Java Beans

...

However, I can't find a reference to these articles (or the knowledge base) anywhere. Have they been relocated or renamed, or do they simply no longer exist?

FWIW, the problem I'm experiencing is described in this (unanswered) thread:

Thanks,

Greg
