Oracle EBS 12.1.3

Jdeveloper 10.1.3.3.0

This is a custom application, where the contents of an advanced table is based on a VO. the requirement is to restrict the records by a search string on field "item".

so I created a search text field, and a button to execute the search. Captured the event in the controller which in turn calls a method in the AM.

// Search items within project lines
 public void srchLineItems(String headerID, String itemSrch)
    {
       System.out.println("inside AM : Method srchLineItems In + ");         if ( itemSrch == null || "null".equals(itemSrch) || itemSrch == "" )
            {
                throw new OAException("Please enter part of the item to search.", OAException.WARNING);
