Error code:-2147467259 Error code name:failed Java desktop application

Hi guys,

I'm trying to run

Java_JRC_Desktop_View_Report_and_set_database_logon downloaded from this link:

http://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/d0d6f979-3e11-2c10-35a8-ac93994a30ed

but at runtime my java desktop application throws this Exception:

com.crystaldecisions.sdk.occa.report.lib.ReportSDKException: org/apache/log4j/Logger---- Error code:-2147467259 Error code name:failed

From what depends?

thx all.
