There is an error in your error page (Seam had an error and forwarded to an error page, which also uses Seam).
You will have to solve the basic error first (get Seam running in general, checking that you have a version that works on AS7, check that you use JSF1.2 libs correctly etc)
Thanks for reply Nicklas:)
