I've had simmilar problems.
I had something like this...
String blah = myResultSet.getString("BLAHBLAH");
if(!myResultSet.wasNull()){
if(blah.equals("something)){ ...boom nullPointer exception
I'm not sure why the null value wasn't caught by wasNull(). Anyway I
worked around it by adding an if(blah!=null){ before I used any string
methods such as the equals(). Hope this helps. If anyone else can
provide an explaination I would be grateful.

I don't know why you're getting a null pointer exception, but your
second query should be just:
SELECT LAST_INSERT_ID()
And maybe you want to invoke getInt() instead of getString()?
