what are the hibernate relationships ?how it connect to mapping file?

October 18 2012

There are one-to-one, one-to-many, many-to-one and many-to-many relationship in hibernate.

For one-to many relationship, you can mention like below in mapping file-

from single mapping side-

<one-to-many class="ClassNameOfManyRelation"/>

from multiple mapping side-

<many-to-one name="single" class="SingleClassName" fetch="select"

</many-to-one>

I am using Struts2,Hibernte 3.3,Display 1.2 in our application.

When we fetching data thorugh hibernate and display data in jsp page using display tag then he retreive data randomly.

Randomly means sometime give old data and sometime give new data. It's not fix what will come result.

Actually Problem is , when we display data in jsp page and user update the record through jsp page and user must show updated record but it's not come properly sometime show old record and new record
