ARRAY object creation problem in Java

Question

Hi I am encountring when trying to create ARRAY in one case
while the same code works perfectly in other case.
The following code works fine:
Connection con=getConnection();
String[][] elements = new String[1][2];
elements[0][0] =new Long(1111).toString();
elements[0][1] =new Long(2222).toString();
ArrayDescriptor desc = ArrayDescriptor.createDescriptor("TYPE1",con);
toReturn = new ARRAY(desc,con,elements);
The following CODE GIVES ERROR :
Connection con=getConnection();
String[] elements = new String[1];
elements[0] =new Long(1111).toString();
ArrayDescriptor desc = ArrayDescriptor.createDescriptor("TYPE2",con);
toReturn = new ARRAY(desc,con,elements);
Please help.
FYI :
type TYPE1 is table of OBJECT : (ID NUMBER, Name VARCHAR2(50));
type TYPE2 is table of OBJECT : (ID NUMBER);
I tried to pass array of long ,int etc in case of TYPE2 but with no advantage.
