Integer nillable property of input parameter bean cannot be null (NumberFormatException in
SimpleTypeMapper)
------------------------------------------------------------------------------------------------------------

                 Key: AXIS2-1883
                 URL: http://issues.apache.org/jira/browse/AXIS2-1883
             Project: Apache Axis 2.0 (Axis2)
          Issue Type: Bug
          Components: databinding
    Affects Versions: 1.1
            Reporter: David Garcia


A property of a complex type is defined like this:

<xs:complexType name="SomeBean">
  <xs:sequence>
    <xs:element name="someInt" nillable="true" type="xs:int"/>
    ...
  </xs:sequence>
</xs:complexType>

That complex type is used as the input parameter of a service´s operation and is defined
like this:

public class SomeBean {
   private Integer someInt;
   ...
   
   ...getters & setters...
}

Then, trying to set that property to "nil" is not allowed.
That is, if the input message is something like this:

<soapenv:Body>
  ...
    <someInt xmlns:nil="http://www.w3.org/2001/XMLSchema-instance" nil:nil="true"/>
</soapenv:Body>

then the following exception is thrown in the server:

java.lang.NumberFormatException: For input string: ""
        at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
        at java.lang.Integer.parseInt(Integer.java:489)
        at java.lang.Integer.<init>(Integer.java:609)

        at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
...

The only way to make it work is to change "someInt"´s type to "int" and pass "0" as default
value, although most time this workaround is not desirable as it breaks the operation´s semantics.

Thanks in advance.
