the ejbRemove method is in the Bena class - you need to call remove() which is a method defined in the home class.
(it is in the super class so you do not see the method in your files).
Thanks for your help. I really works now.
For beginners this is a little bit confusing. In Monson-Haefels "Enterprise JavaBeans" the ejbRemove-method is used that's why I've tried it this way all the time...
