Question about webservice returning array with nillable=fals

[fheldt]

I've got a problem with a webservice and no idea how to solve this. Maybe someone can give me a hint:

Java Webservice snippet:

@WebMethod
public Integer[] GetSteps(String ugid) {
 Session session = (Session) em.getDelegate();
 List<?> list = session.createSQLQuery("SELECT QVZAHL FROM MQVAL WHERE QVUGRP=:ugid AND QVSTAT<>'*'")
 .addScalar("QVZAHL", Hibernate.INTEGER)
 .setString("ugid", ugid)
 .list();
 return list.toArray(new Integer[list.size()]);
}

Now i want to use this in a C# .NET project, it generates this

public System.Nullable<int>[] GetSteps(string arg0) {
 object[] results = this.Invoke("GetSteps", new object[] {arg0});
 return ((System.Nullable<int>[])(results[0]));
}

As you see, it generates a function returning an array of nullable ints.

The question is: how can i change the Java webservice so that the elemnets of the array are nillable=false. Is there any annotation to do this?

Thanks in advance for any help.

Hi,

let JBossWS generate your WSDL first. Then copy it somewhere and modify its schema. Then update your Webservice java code (using appropriate annotation) to use your modified WSDL file instead of generated one.

In particular I guess you get non-nillable elements using an array of primitive int instead of an array of Integer.
However generally speaking, what Richard suggest you is the best solution whenever you need to force some constraints on the service contract (see the top-down approach in the documentation).

I changed the wsdl by hand and it works now, but i also investigated this topic a little further. No matter what i change the return type to, JBossWS always generates the same result (and that's a bug imho):

@WebMethod
public Integer[] GetSteps(String ugid) {
...
}

or

@WebMethod
public int[] GetSteps(String ugid) {
...
}

give both

...
 <xs:schema targetNamespace="http://jaxb.dev.java.net/array" version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema">
 <xs:complexType final="#all" name="intArray">
 <xs:sequence>
 <xs:element maxOccurs="unbounded" minOccurs="0" name="item" nillable="true" type="xs:int"/>
 </xs:sequence>
 </xs:complexType>
 </xs:schema>
...
 <message name="QMWebService_GetStepsResponse">
 <part name="return" type="ns1:intArray">
 </part>
 </message>

in the int[] case i would suppose nillable="false", else nillable="true", right?

Hi,

yes, you're right:

This is the JAXB related issue.
