Dear all I am getting below error when i perform insert operation between two tables.
scenarion:
Table1:Category
Table2:categorycategoryrelation(one to many relationship with category table)
in category table i have a columns id,name and in categorycategoryrelation table i have columns parentcategoryId,childCategoryId and these two id are coming from category table(id)
i am using spring MVC with portlets
this is the error i am getting
Category.java
CategoryCategoryRelation.java
In my controller first I am inserting category into category table and then i am adding child to this category.In my Dao I am using SessionFactory.getCurrentSession() for CRUD oprations
can some one tell me how can i solve this
Database tables:
Category
id(pk)
name
description
CategoryCategoryRelation
parentCategoryId
childCategoryId
both are pk,fk which are refered to id column in category table
