Hi ,

I have an entity class which has 15 columns

I am writing a query in my java class to retrieve 2 columns from the table related.

This particular table has huge amount of records in the table say 1,00,000 records

All the settings in the persistence.xml file are same when it was generated

When i start to run my java program , i was seeing the records fetching in my console but after some time say 2min , the connection with the hibernate is lost and i am receiving null pointer exception ?

Do we have any way so that we can extend the hibernate connection so as to the data is not lost ?

Thanks
Mahi
