Well I´m using Seam 2.0 with tomcat 6 and MySQL 5. I have the following configuration files:

When I tried to the ConfigList.xhtml(this is a generated Seam file) I got the following errors:

Please, any idea about this error will be accepted gratefully!

1. Re: Error reading 'resultList' on type

genman Apr 1, 2009 1:45 AM (in response to mhdez)

I'm guessing it's failing because the call to configList.getResultList() is failing. You could try to add more debugging to your own class.

I think is a configuration problem because ConfigList.xhtml and others files are created by the seam-gen. Something about the database handling is missing I think...well thanks for answer me...I will be open to any suggestion!
