    Unhappy Pentaho Report Designer 5.0.1 and windows server 2008 64 bits

    Hello Guys,
    I have a problem with pentaho report designer. I use :
    - windows server 2008 64 bits
    - ODBC 64 bits
    - pentaho report designer 5.0.1
    - pentaho bi server 5.0.1

    My problem is : where I want to design a new report , I add a new query, the connection to the database is ok. But when I clik on "preview" , it puts an error : invalid string or buffer length.

    I don't know why I am this error.
    Then when I try to publish on pentaho bi server any report I got this error in firefox : error parsing parameter info / report validation failed

    Sometimes I think it's a bug of pentaho tools? Or pentaho don't workson windows server 2008 64 bits?

    Please Guys Help me It's urgent !!! I don't know what do

    ODBC is notoriously fragile. If possible use a native JDBC driver (all major database vendors produce such drivers).

    If you use ODBC-32, you will have to make sure that your report-designer and BI-server use a 32-bit JDK. You cannot link 32-bit code in a 64-bit process.
