***UDF not working

Question

Hi all,
My requirement is ,if if the ownership = "", 0, or "O" then don't send else send the original value.
                           Source value              Target
Suppose ownership is 0----
Blank
                                 O----
Blank
Blank
                               Test----
Test
If I pass any other value other than O ,0,"",it should be populated.
For this I wrote a UDF as below.
if ( ! ( inValue[ 0 ].equals("") || inValue[0].equals("O") || inValue[0].equals("0") ) )
  result.addValue(inValue[0]);
else
  result.addValue("");
When I Test this in Test tab ,it is working fine But it is Populating even O ,0 in the database table.
                  Source             Target
this is if I pass O -
>O
                      0----
>0        
This should not happen.
Can any one help me out in this regard.
Thanks,
Srinivasa

I am using graphical mapping as below.
Ws(fileld name) same for both source and target.
ws-               equals(test function)---
                                                            OR
                    Constant O----
                     equals(test function)---
                                                            OR
                    Constant 0----
                      equals(test function)---
                                                            OR
                    Constant ""----
ie if equals=0 or O or" " then poplulate constant []
esle populate WS
error
Cannot insert null in to ws.
then I tried this way:
e if equals=0 or O or" " then poplulate constant ['']
esle populate WS
now error.
