New to Hibernate. Working on a sample. I am getting
"net.sf.hibernate.MappingException: Bad identifier type: net.sf.hibernate.type.ComponentType" - error. I tried my best to find out from this forum to resolve it but not succeeded. The mapping files are generated through Hibernate tools
Please help me. The details are as follows:
