Re: "is it always so hard for SOAP interop?" The answer is that it is easy if someone has already done the interop coding. In this case, you are using Apache SOAP as the client. Development of Apache SOAP has mostly stopped, with effort being applied to the "next generation", which is Axis. Interop with the SOAP Toolkit is pretty well understood, since the SOAP Toolkit (version 2.0, at least) was available last Spring while Apache SOAP development was still very active. As .NET got to later betas and people were using it more, Apache SOAP development was less active, and less interop work was done (or at least "published"). Anyway, I better stop now, because I am not an interop expert by any means. I have worked with Apache SOAP, SOAP Toolkit 2 and SOAP::Lite (perl), but that's it.
I think the thing to focus on is the point made by Simon Fell, which I take to ultimately mean that the problem lies in the encodingStyle attribute. When I look at "The SOAPBuilders Interoperability Lab" (http://www.xmethods.net/ilab/) and click the link for the .NET beta 2 client, what strikes me about the wire dumps of the client is that the encodingStyle attribute *is* present, and it is SOAP encoding. I do not know whether this means Microsoft switched the default encoding, or whether for interop testing the .NET client forced the encoding. While I understand you are using a .NET server with an Apache client, the presence of the encodingStyle is interesting nonetheless, and I am wondering whether a small change to your server code would make your .NET server accept messages from Apache SOAP. An excerpt from the .NET interop server code is: namespace Simple { using System; using System.Xml; using System.Web.Services; using System.Web.Services.Protocols; using System.Xml.Serialization; using System.IO; using System.Web; [WebService(Description="These operations implement some simple Section 5, rpc-style SOAP operations, for interop testing. Please email [EMAIL PROTECTED] with any questions.", Namespace="http://soapinterop.org/";)] [SoapRpcService(RoutingStyle=SoapServiceRoutingStyle.RequestElement)] public class SimpleTest { [WebMethod] [TraceExtension(Filename=@"C:\interop.log")] [System.Web.Services.Protocols.SoapRpcMethodAttribute("http://soapinterop.or g/", RequestNamespace="http://soapinterop.org/";, ResponseNamespace="http://soapinterop.org/";)] [return: SoapElement("return")] public string echoString(string inputString) { return inputString; } } Are there any attributes in this code that you do not use? The WSDL for this service is available at http://www.mssoapinterop.org/asmx/simple.asmx?WSDL. This appears to use SOAP encoding.

I notice that .NET does not specify SOAP-ENV:encodingStyle for either the request or response. This may be what Simon means by "doc/literal", but I am not sure. In Apache SOAP, the encoding style is set on the Call object (call.setEncodingStyleURI), each parameter constructor (the final argument, null in your case) and each mapping for complex types (smr.mapTypes). The value is used both for the attributes placed into XML and to locate the proper serializer or deserializer. Without testing this myself, I would suggest you could try using an empty string for call.setEncodingStyleURI, and add an type mapping for an empty encoding URI: Serializer cleanSer = new Serializer() { public void marshall(String inScopeEncStyle, Class javaType, Object src, Object context, Writer sink, NSStack nsStack, XMLJavaMappingRegistry xjmr, SOAPContext ctx) throws IllegalArgumentException, IOException { nsStack.pushScope(); SoapEncUtils.generateStructureHeader(inScopeEncStyle, javaType, context, sink, nsStack, xjmr); sink.write(Utils.cleanString(src.toString()) + "</" + context + '>'); nsStack.popScope(); } }; smr.mapTypes("", null, String.class, cleanSer, null); call.setEncodingStyleURI(""); Scott Nichol ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, February 22, 2002 11:57 AM Subject: Re: java client for .NET - what do i ignore ? right, i can test it, but how do you specify that you send a doc/literal request ?? shall i change the strange parameter : Constants.NS_URI_SOAP_ENC to something else ??

That correct for calling MS Toolkit 2.0 services, but not for .NET. .NET by default does doc/literal SOAP, not rpc/encoded, you're sending an rpc/encoded message, which .NET will largely ignore. You need to send a doc/literal request. Not sure how you cook those up with the 2.2 code.
