Am trying to write a method that fetches records from DB and prepares a tree. I have uniqueID and parentID fields in records. Am trying to find a parent from the already built tree to insert new records using recursion. But my tree only builds upto level 2. After that it fails to return proper parent nodes. Below is my code
//Code calling the recursive code :


In recursive method i have to return the previous parent node to continue iteration of while loop. But am not able to figure out what i should return. Please help asap.
 
It is sorta covered in the JavaRanch Style Guide.
