Problem with WSIF-AXIS server deserialization with int types

[Susana Alejandro]

I am developing the access to a Web Service using WSIF, JROM as schema and 
two providers Apache SOAP and Apache AXIS.

The web service is a simple calculator where two numbers are added. I have 
two different methods, one with int parameters and the other one with String 
parameters.

When I use Apache Soap provider the execution goes ok in both cases, with 
int parameters and with String parameters, but if I use Apache AXIS then the 
execution with the String parameters goes ok but with int parameters I have 
got an error when the deserialization begin at the server side. The 
exception is

JAXRPC.TIE.01: caught exception while handling request: deserialization 
error: java.lang.NumberFormatException: For input string: ""

Anybody knows where is the problem? I can attach the source of my code if it 
is necessary.

Thanks in advance.
Susana.
