hi ,
  i'm using finder meathod ... suppose findxxx(), and i'm searching in the database on the basis of follwing keyword which i'm passing as a argument in the finder meathod .. but suppose if the keyword dosent exist in the database .... thats what is happening in my case ... whenever i used to execute that query that funtions dosent returns anything and the control finishes from there ....
but i want is that if the keyword dosent exist then it should return null to me .... can u tell me how can i do this that if the keyword dosent exist in the database then it should return null....

regards
Raj.......

Hi Raj,
You can try checking number of records in the ResultSet if they are 0 then return null else the results

Write a finder that returns a collection of keywords. Then, if the keyword is not in the database, the finder can return an empty collection.

As a rule, nulls are evil and should be avoided if possible.
