Hello Guys,

I use pentaho report designer 5.0.1 on windows server 2008 64 bits. when I run it and add a new connection to a database its ok. But when I add a query and I clik on "preview" he puts an error like "org.pentaho.reporting.engine.classic.core.models: Accessing to resultset failed"
I don't know why I have this error because when I run pentaho report designer on windows 7 , it's works but on windows server 2008 I don't know why I can't save my queries.

I need an help please !!!!
