Hibernate plugin for Eclipse

HIberclipse supports only hibernate2.0 package
structure for example when i tried to generate code
using the hbm2java it gave the the following exception

java.lang.NoClassDefFoundError:
net/sf/hibernate/tool/hbm2java/CodeGenerator
Exception in thread "main"

This shows that hiberclipse is still using
net.sf.hibernate.tool package structure.
