wsdl2java generated client throws NumberFormatException on nil integer
----------------------------------------------------------------------
Key: AXIS2-1247
URL: http://issues.apache.org/jira/browse/AXIS2-1247
Project: Apache Axis 2.0 (Axis2)
Issue Type: Bug
Affects Versions: nightly
Environment: Java 1.4.2, Tomcat 4, Axis 2 Nightly Build
Reporter: Todd Doolittle
Priority: Critical
I used wsdl2java to create a client based on wsdl from a non-java service. The
wsdl specifies that one of the returned values is an integer and is nillable
like this...
<xsd:element name="ksn" nillable="true" type="xsd:int" />
When the service returns a null/nill value it looks like this in the SOAP body:
<fjs1:ksn xsi:nil="true"/>
The client code throws a number format exception while processing this...
Caused by: java.lang.NumberFormatException: For input string: ""
at java.lang.NumberFormatException.forInputString(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)

Here is the SOAP message my client sent (which looks fine):
POST /ws/r/poc?WSDL

SOAPAction: getinfo
