Re: nullPointerException when accessing fields of an object

i have had a lot of the same types of problems in the different data bases i work with. not exactly the same product.

what we had to do was GET only objects, and then, something like,

   String sDataObject = String.valueOf(oDataObject);    if (sDataObject.equals("null")){sDataObject = "";}

i would get the null pointer error when, putting sql null's into hashtables as a value and not even a key. and sometimes into other Container Classes, but i didn't narrow this down.

we had problems with number's coming back as SQL null.
