Re: [Wrapper-user] WrapperSimpleApp can not access a member of class myClass with modifiers "public static"

[Leif M. <lei...@ta...>]

Andy,
Sorry for the delay getting back to you.  Yes that would do it.  See
the error message:

java.lang.IllegalAccessException: Class
org.tanukisoftware.wrapper.WrapperSimpleApp can not access a member of
class xml2db.ExcelDataImporter with modifiers "public static"

I will think about how to make the meaning of the error a bit clearer.

Please let me know if oyu have any other questions.

Cheers,
Leif
