Hibernate Code Generation don't works

I try to generate the Java domain objects from existing database, as it in this article: http://www.javamagazin.de/itr/online_ar ... id,11.html described. I use JBossIDE 1.5 Bundle. I can make all steps till Code Generation. It reads the database schema correctly. But, if I try to genarate the code, I get an error:

Code:

org.hibernate.console.HibernateConsoleRuntimeException: Could not create or find  with one argument delegate constructor
  java.lang.ClassNotFoundException:
 
    java.lang.ClassNotFoundException: 

this exception I get with any possible generation configuration. Only if I deactivate the checkbox "Reverse engineer from JDBC connection", it throws no errors. And, althought I turned the log level in the hibernate-log4j.properties to DEBUG, it tells me nothing about this error and this problem, I get no stack trace, I don't know even which class it missed!
The error log from the starting of the code generation till the cancelling through the error is following:

Code:

I have updated my Eclipse IDE with automatic updates manager to 1.6GA. The version of Hibernate Tools is 3.1.0 beta 3. This has not helped, I get the same error.

do you have the console configuraiton path set to the correct classpath for the reverse engineering stragy you have set ?

if you haven't set any reverse engineering strategy then i'm quite sure something is "screwed" in your eclipse/hibernate tools mix - try and run eclipse with the -clean argument and if that does not work try and do a clean install.
