Invoking axis 1.2rc3 webservice returning an array from .NET framework 1.1
Hi,
I have been struggling to invoke a webservice method which returns any
type of array from .Net. Whenever I call a method for eg.
string[] list() found in http://127.0.0.1:8080/axis/EchoHeaders.jws
i get an error saying Unhandled Exception:
System.InvalidOperationException: There is an error in
XML document (1, 308). ---> System.InvalidOperationException: The
specified type was not recognized: name='string',
namespace='http://schemas.xmlsoap.org/soap/encoding/', at
<whoamiReturn xmlns=''>.
What am I doing wrong here? is there a work around for this problem?
really appreciate if someone could help me out.
thanks.
Harsha
Re: Invoking axis 1.2rc3 webservice returning an array from .NET framework 1.1
Posted by Anne Thomas Manes <at...@gmail.com>.
Because the schema says elementFormDefault="qualified" then the <item>
elements should be qualified, so I don't understand why the client is
producing unqualified <item> elements.
What version of Axis are you using?
Can you wait for the final release of 1.2? (Dims says it should be
available in a couple of weeks.)
If not, then you might try Sun's JAX-RPC RI in the JWSDP. (Check the
license carefully to make sure that you may redistribute it.) My
experience with the JAX-RPC RI, though, has proven to be less
interoperable with .NET than Axis is.

Fwd: Invoking axis 1.2rc3 webservice returning an array from .NET framework 1.1
Posted by harsha senanayake <ha...@gmail.com>.
Hi Anne,
After you mentioned that Axis gives a wrapped array no matter what, I
tried changing the encoding the document/literal. With
document/literal the WSDL is generated properly :
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions targetNamespace="http://integration"
xmlns:impl="http://integration" xmlns:intf="http://integration"
xmlns:apachesoap="http://xml.apache.org/xml-soap"
xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">
<!--WSDL created by Apache Axis version: 1.2RC3
Built on Feb 28, 2005 (10:15:14 EST)-->
<wsdl:types>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://integration" elementFormDefault="qualified">
<element name="in0" type="xsd:string" />
<complexType name="ArrayOf_xsd_string">
<sequence>
<element name="item" type="xsd:string" minOccurs="0"
maxOccurs="unbounded" />
</sequence>
</complexType>
<element name="getArrayOfStringReturn"
type="impl:ArrayOf_xsd_string" />
</schema>
</wsdl:types>
<wsdl:message name="getArrayOfStringResponse">
<wsdl:part name="getArrayOfStringReturn"
element="impl:getArrayOfStringReturn" />
</wsdl:message>
<wsdl:message name="getArrayOfStringRequest">
<wsdl:part name="in0" element="impl:in0" />
</wsdl:message>
<wsdl:portType name="SapumoPort">
<wsdl:operation name="getArrayOfString" parameterOrder="in0">
<wsdl:input name="getArrayOfStringRequest"
message="impl:getArrayOfStringRequest" />
<wsdl:output name="getArrayOfStringResponse"
message="impl:getArrayOfStringResponse" />
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="sapSoapBinding" type="impl:SapumoPort">
<wsdlsoap:binding style="document"
transport="http://schemas.xmlsoap.org/soap/http" />
<wsdl:operation name="getArrayOfString">
<wsdlsoap:operation soapAction="" />
<wsdl:input name="getArrayOfStringRequest">
<wsdlsoap:body use="literal" />
</wsdl:input>
<wsdl:output name="getArrayOfStringResponse">
<wsdlsoap:body use="literal" />
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="SapumoService">
<wsdl:port name="sap" binding="impl:sapSoapBinding">
<wsdlsoap:address location="http://localhost:801/services/sap" />
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
with the exception of <element name="getArrayOfStringReturn"
maxOccurs="unbounded" type="impl:ArrayOf_xsd_string" /> where I had to
take out maxOccurs="unbounded" attribute as .net complained about it.
I think this must be another bug in java2wsdl as maxOccurs="unbound"
should only be present in the wrapped array type. Anyways now Axis
gives the following SOAP message :
- <soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
- <soapenv:Body>
- <getArrayOfStringReturn xmlns="http://integration">
<item xsi:type="xsd:string" xmlns="">Harsha</item>
<item xsi:type="xsd:string" xmlns="">Prabath</item>
<item xsi:type="xsd:string" xmlns="">Senanayake</item>
</getArrayOfStringReturn>
</soapenv:Body>
</soapenv:Envelope>
which seems to conform to the WSDL. I am not sure if xmlns="" must be
causing an issue, but even when i forced that in still .net client
gives an NPE.
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("",
Use=System.Web.Services.Description.SoapBindingUse.Literal,
ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Bare)]
[return: System.Xml.Serialization.XmlArrayAttribute("getArrayOfStringReturn",
Namespace="http://integration")]
[return: System.Xml.Serialization.XmlArrayItemAttribute("item",
Namespace="http://integration", IsNullable=false)]
public string[]
getArrayOfString([System.Xml.Serialization.XmlElementAttribute(Namespace="http://integration")]
string in0) {
object[] results = this.Invoke("getArrayOfString", new object[] {
in0});
return ((string[])(results[0]));
}
Is there anything I can do to fix this? or is there any other
opensource SOAP engine I can use?
thanks,
Harsha.

Re: Invoking axis 1.2rc3 webservice returning an array from .NET framework 1.1
Posted by harsha senanayake <ha...@gmail.com>.
Hello Anne,
I am sorry for raising a question without thoroughly going through the
wiki & the mailing list. I am new to the webservices business, and I
realized the main reason for that error was using the default rpc
encoding -- and after i changed it to wrapped/literal .net client
stopped throwing the exception. I know this should have been the first
thing i should have tried, but i was not aware of different styles of
encoding SOAP messages. But even after I switched to wrapped/literal I
had this issue where .net client just returning the 1st element of the
array. Dino suggests to use the write WSDL first approach, but this is
not possible as I am using Mule (muleumo.org) for exposing components
via SOAP and other mediums. I applied the Eric's patch but the problem
didnt go away.

This is a code extract from the C# proxy class :
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("",
RequestNamespace="http://DefaultNamespace",
ResponseNamespace="http://DefaultNamespace",
Use=System.Web.Services.Description.SoapBindingUse.Literal,
ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
[return:
System.Xml.Serialization.XmlElementAttribute("getArrayOfStringReturn")]
public string[] getArrayOfString(string in0) {
object[] results = this.Invoke("getArrayOfString", new object[] {
in0});
return ((string[])(results[0]));
}
and yes I tried changing the above to
System.Xml.Serialization.XmlArrayItemAttribute("getArrayOfString")]
which resulted in a NPE. I also noticed that after applying Eric's
patch the only change in the SOAP message was -
<ns1:getArrayOfStringReturn xmlns:ns1="http://integration"> tag.
I also went through Dino's excellent writeup -
http://wiki.apache.org/ws/FrontPage/Axis/DotNetInterop but i am
confused how he got the array samples to work, may be because he used
the write WSDL first approach. What am i still doing wrong? I will
really appreciate any suggestions to overcome this issue.
thanks,
Harsha.

Please see Dino's extremely informative wiki on Axis/.NET array interop:
http://wiki.apache.org/ws/DotNetInteropArrays
You also may need to install Eric's famous patch. See:
