Error accessing NewEntity from Admin
Posted: Fri Oct 23, 2015 11:11 pm
SOLVED, ManufacturerImpl should implement Serializable interface
Hello
I followed the tutorials
http://www.broadleafcommerce.com/docs/c ... new-entity for adding a new Entity
and
http://www.broadleafcommerce.com/docs/c ... m-entities
for creating a new Entity called Manufacturer and accessing it from admin panel.
The problem is that at the panel a receive the message
...java.lang.ClassCastException: com.mycompany.sample.domain.ManufacturerImpl cannot be cast to java.io.Serializable...
I have spend hours and hours but i didn't manage to make it work, so any help would be mauch appreciated. My code is
Manufacturer Class
Manufacturerimpl Class
the db table is EVS_MANUF with 2 columns MANUF_ID and MANUF_NAME.
Also i modified all the files mentioned in the tutorial (persistence.xml, applicationContext.xml)
Am i missing something?
