    Default Sealing violation loading derby

    I'm trying to install the mondrian-embedded package. I deployed the application
    in tomcat 5.5 ( I use java 1.5.x )
    Here is the error when I try to click on "JPivot pivot table" (from catalina.out
    Do you know how to circumvent this?

    Best Regards,

    Caused by: java.lang.SecurityException: Sealing violation loading org.apache.derby.jdbc.InternalDriver : Package org.apache.derby.jdbc is sealed.

    Default Solution / hack

    Uncompressing the derby.jar file in WEB-INF/classes it works..
    Are there cleaner solutions?
