Sorry, I can't find where Sosnoski says that minOccurs=1 by default for 
every kind of parameters is the best solution.
He said that it's the best to use minOccurs=1 for primitives (as I 
said), while he preferred to keep on using minOccurs=0 for object types, 
while I was saying it was preferrable to use nillable=true because of 
.NET compatibility.

Moreover, if you use minOccurs=1 always, generating a client with Axis2 
from the resulting WSDL, will then lead to the use of primitives that 
CANNOT let you specify a null value.

So, the actual result is:

=> starting from public Integer methodA(Integer a);
=> Java2WSDL generates a WSDL with both the return type and the 
parameter type as mandatory (minOccurs=1, not specified but inherited as 
XML Schema default)
=> if you generate a client with WSDL2Java you'll get:
public int methodA(int a);

So, a client would not be able to call the service speciying null as the 
input parameter and could not handle null as the return type.

That's not good at all!
