*And I checked that class not founded is in my classpath (is reachable from source code)
*Triying to avoid conflicts, i removed all possible conflicts, using a minimal configuration (keeping only essentials lib in my classpath: hibernate core and mysql driver ) Neither worked

• Also installing complete version of last JBoss Tools (with all its features -not only Hibernate Tools) via Elcipse MarketPlace. Neither worked
