Take a look at the source code. I found out the problem is that wsdl2ksoap 
doesn't support namespaces well. They are hardcoded, for example 
(WSDLParser.java:52):

NodeList nodes = doc.getElementsByTagName("wsdl:service");

I tried to process wsdl (https://webapi.allegro.pl/uploader.php?wsdl) that 
doesn't use "wsdl" prefix for element "service", because it's defined as the 
default (unqualified) xmlns. Unfortunately that causes NullPointerException at 
line 55.

I guess your problem is pretty much the same.

As I mentioned in my previous comment, fixing namespaces and rebuilding sources 
fixed the issue. But another problem appeared - classes aren't generated at 
all. After digging through the source code with debugger I found that 
wsdl2ksoap simply does not support complexContent and schema restrictions. It 
only generates code for complexType with elements in it. So don't bother trying 
to parse heavy WSDLs.
