===

I am have followed the following link to integrate GWT  with Hibernate. 
<https://developers.google.com/web-toolkit/articles/using_gwt_with_hibernate>

i have downloaded the sample code of GWT-Hibernate integration using gilead.
When i have tried to save the record, get the following error 

>Parameter 0 of is of an unknown type 'com.google.musicstore.domain.Account/3669536145'

But when i have checked the command line,found the following trace,
