Issues integrating AXIS Web Services with .NET

I have been integrating with ITIM 5.0 using the unsupported Web Services that use AXIS 1.3. All of the issues I have experienced were fixed in 1.4, and seeing as the product is over 5 years old, I don’t understand why they chose to stick with an older version. There are several issues I have found besides the well published one about how AXIS represents arrays by pointing to a centralized value store. One of those issues is namespacing. AXIS tends to generate WSDL with a namespace, but the return values do not have a namespace, .NET just fails to find the value during deserialization. It took me forever to find out why, but I solved it by manually removing the namespace requirement from the proxy code. The second issue I ran into was how the WSDL represents collections of items. The collection is named SomeCollection with the items underneath being named Item. When the service returns, the items are named the same as the collection (SomeCollection contains SomeCollection(s)). I had to manually rename all of these references in the proxy to be the same as the collection. These cost me countless hours. If I find anymore I will post them here. Obviously the solution is to upgrade to 1.4, but IBM won’t support it or turn over the source code to do so.

    Thank you very very much for your post:
    it really saved me ‘countless hours’.

    I was trying to call from .Net 3.5 an Axis 1.4 web service with this schema:

    and the request was OK, but with answer = null (genDocResponse=null).

    I did remove the namespace requirement from the proxy code:

    [return: System.Xml.Serialization.XmlElementAttribute(“genDocResponse”, Namespace=””)]

    and now I get the answer correctly.

      Hi Marco,

      It seems like I’m having the same problem; but I don’t know where I have to remove the namespace requirement from the proxy code.

      Can you help me? Which file do I have to change?

        Hi Marco,

        In my Reference.cs doesnt’ appears “System.Xml.Serialization.XmlElementAttribute” but I have something like that: “System.Xml.Serialization.SoapTypeAttribute” so I tried to remove de Namespace from there without success.

        Otherwise, I always get the same exception when call a method that return a Array of objects:
        “The specified type was not recognized: name = ‘ArrayOf_tns1_[Class_Name]'””

        I’m using .NET 3.5 SP1 Visual Studio 2008 and calling a WebService developed by a third party on Apache Axis version: 1.4.

        Any help?

        Thanks in advance.

    Try to add this web service in VS2008

    Just can’t…in firefox show the response…but in IE don’t work

    • Jeremy Mullinax-Hill

      The web server is throwing an error related to HTTPS/SSL. Here is the original error:

      Error 117 (net::ERR_BAD_SSL_CLIENT_AUTH_CERT): Unknown error.

      This can mean any number of things but probably means either the web server is not properly configured for HTTPS or is behind a firewall that is not passing the request through properly. I’ve seen this before with a mis-configured SSL accelerator. An SSL accelerator is a hardware device that handles all of the security ticket translation and sends the request back to the server as HTTP instead of HTTPS. If the server is expecting HTTPS it will fail. This is just one possibility.

      I get similar results no matter what browser I use. You need to contact the support person for that service and have them look into it.

    Thank you! It worked like a charm! You can also view the response with SOAPUI to compare the namespace retrieved
