RE: Axis using wrong encoding for array in Doc/literal
Thank You Anne for your reply.
After this I tried out defining the array in the wsdl in the same way as
axis is sending the response on wire and the web service worked with .NET
But now axis generates wrong client stubs from the wsdl
My java Class is
-------------------------------------------------------------
service1.java
--------------------------------------------------------------
public class service1 {
public bean1 returnarr() {
bean1 a=new bean1();
int[] b=new int[3];
b[0]=1;
b[1]=2;
b[2]=3;
a.setMyArr(b);
a.setA(6);
return a;
}
public int[] echo() {
int[] a=new int[2];
a[0]=1;
a[1]=2;
return a;
}
}
My Wsdl that I send to .net is
In this wsdl I have fixed the echo method to have exactly the same signature as axis
sends arrays back on wire
-----------------------------------------------------------

And finally the .NET Client works
The problem now is that the client stubs generated with this wsdl for axis are incorrect

Subject: RE: Axis using wrong encoding for array in Doc/literal
.NET is throwing an error because the WSDL response message definition
doesn't match the structure of the returned message. The WSDL says that the
message looks like this:
<wsdl:message name="returnarrResponse">
<wsdl:part element="intf:returnarrResponse" name="parameters"/>
</wsdl:message>
where intf:returnResponse looks like this:
<element name="returnarrResponse">
<complexType>
<sequence>
<element name="returnarrReturn" type="impl:bean1"/>
</sequence>
</complexType>
</element>
and impl:bean1 looks like this:
<complexType name="bean1">
<sequence>
<element name="a" type="xsd:int"/>
<element name="myArr" nillable="true" type="xsd:int"
minOccurs="0" maxOccurs="unbounded"/>
</sequence>
</complexType>
This looks like a very nice doc/literal definition. Note that this
definition doesn't use the SOAP encoding-based ArrayOf_xsd_it datatype.
On the wire, though, Axis is in fact returning the ArrayOf_xsd_int type:
<complexType name="ArrayOf_xsd_int">
<complexContent>
<restriction base="soapenc:Array">
<attribute ref="soapenc:arrayType" wsdl:arrayType="xsd:int[]"/>
</restriction>
</complexContent>
</complexType>
