Document/literal web service with WSDL

Hi
I is so hard to get an easily written example of how to do a Document/literal web service in java, to generate a WSDL descripbing it and then deploying it on Apache.
I first belived that I should use JAXM. But I think it is just SOAP and there is no way to generate a WSDL file for the JAXM service, or??
It seems that u can to document/literal style using JAX-RPC, but this is VERY strange since RPC style is the direct opposite of Document style.
well, well
I would be very greatful for information here.

JWSDP 1.2 includes the WS-I sample application in JWSDP_HOME/wsi-sampleapp. Several components of
this application use document-literal operations. The architecture of the application is described
here http://ws-i.org/SampleApplications/SupplyChainManagement/2003-04/SCMArchitecture1.0-BdAD.pdf
The WSDL for the services is availabe from URLs in the document.
As you say, the trick is generating the WSDL for a new service. You have two options: 1. Modify
existing WSDL yourself. This might be fairly easy, since the only major changes will be in the
schema. Then use a tool to generate Java source code from the WSDL. 2. Use a tool to generate WSDL
from source files.
I prefer option 1 myself, since that gives me total control over the schema. It allows me to
serialize certain parts of the SOAP message as body elements, others as attributes, and others as
header elements. Then I use the Apache Axis tool WSDL2Java with the "-s" option to generate skeleton
service files. One big advantage to this approach is that WSDL2Java generates JavaBean class for the
types in the WSDL schema, so I don't need to build the SOAP message with SAAJ. A service client
generates stubs and calls the service exactly as it would for an rpc/encoded service.
wscompile also generates service files from WSDL if you give the "-gen:server" option, but I've only
used Axis for my services.
Here's a sample WSDL for a document/literal service you can modify as you need. I checked it with
the WS-I testing tools to be sure it conforms to the WS-I Basic Profile 1.0a (available at www.ws-
i.org). Notice that the processPo operation is a request-response type operation, even though it has
a document/literal style. This follows the recommendations in the Basic Profile.
Cheers,
Mike

    Hi Dave,
    One reason to have the SeiValidationException is when you do not follow the java bean convention for getter/setter or some of the public methods you want to expose are not throwing the right execption.
    Using the command line utility genProxy [or the ant task] with the debug flag may give you some informations about the WSDL constructs WSA do not understand. Look at the following how-to to get started:
    http://www.oracle.com/technology/tech/java/oc4j/1013/howtos/how-to-ws-bottomup/doc/how-to-ws-bottomup.html
    If this does not help, can you share your WSDL with us ?
    Thanks,
    Eric

  • Leverage Inheritance Benefits in 'document/literal' Web Services

    Greetings,
    I have developed a document/literal web service that receives an object I created, say ParentObject.
    I developed it under the assumption that once I create a web service for ParentObject, I'll be able to use the same web service for ChildObject as well, which is a sub-class from ParentObject. Unfortunately, it did not work.
    Please correct me if I'm wrong; is it really not possible to leverage inheritance capabilities web services? And if it's not possible, what workaround(s) do you use in such scenarios when you don't want to create a new web service for each object type despite that they all have the same logic?
    Your thoughts are highly appreciated.
    Thanks in advance,
    Ahmed Motaz

    Jason, have you made any progress with CF7 and WS Security?

  • Question about document/literal web service

    Hello every body.
    I have some question about document/literal web service.
    I’ve been working with Axis before.
    Axis has four valid signatures for your message-style service methods:
    public Element [] method(Element [] bodies);
    public SOAPBodyElement [] method (SOAPBodyElement [] bodies);
    public Document method(Document body);
    public void method(SOAPEnvelope req, SOAPEnvelope resp);
    The same I am trying to do with WebLogic API for webservices.
    But when I am trying to test web service (public Document method (Document body); )
    I have serialized exceptions for org.w3c.dom.Document.
    Do I have to write a custom class for org.w3c.dom.Document serialization?
    If yes can you give me some idea or example?
    The all idea behind this web service is. I have just one web service and mane classes for XML processing. Depends what xml document will be during runtime, web service will be using different class for xml processing. It works fine with Axis, but in case of WebLogic I have some problem.
    One more question… How I have to call this web service from java client?
    I have seen this example http://www.manojc.com/?sample31 ,
    but this web service looks like (Document helloDom()). I need to send Document.
    This example works for Dynamic Proxy, but does not work for static call.
    Any ideas?? Thank in advance.

  • Future of Document/Literal Web Services in CF

    I would like some clarification on the future of web services
    in CF. Right now I use CF 7 RPC/encoded CFCs which communicates
    with a Java client product currently using the older JWSDP 1.6 for
    web services. However the new Java SOA with WS-Security has been
    out for a while but I cannot convert to it because it doesn't
    support the outdated RPC/encoded format and CF 7 does not handle
    Document/Literal properly. CF 7 does not properly handle cfproperty
    element arrays in publishing Document/Literal web services (well
    documented problem with CF and the current Axis engine).
    However JavaSE 6 is nearing a release and it too will not
    support RPC/encoded or xsd_AnyType, nor will it support the current
    Document/Literal produced by CF 7 which does not properly handle
    arrays for cfproperty elements. This may become a major problem for
    my application as all the Java environments are upgraded.
    Therefore is this issue being addressed in the upcoming CF 8
    release?
    Will CF 8 be upgraded to Axis2 and properly support
    Document/Literal arrays for cfproperty elements?
    When might we expect a release of CF 8?
    Is it possible for CF 7 to use Axis2?
    CF has been a great product but I do need to assess some
    options if CF can not handle Document/Literal arrays for cfproperty
    elements within the near future.

  • Problem with document/literal web services

    Hi,
    I need to publish a document\literal WSDL for a web service on my OC4J 10.1.2.2 because my app has an interface with a .NET system.

    The deployment worked fine but when I'm trying to access the web service with the generated stub I'm getting the following message:
    "These methods do not conform to the restrictions imposed by the web service implementation"
    and then a list of these methods.
    Later I tried to remove the parameters from the methods and regenerated the WSDL and it worked fine, but I need the methods with the parameters.

  • Complex schemas using Document Literal Web Services

    I am trying to use document style web services and top down approach. I prepared a request, response and fault schema. In those schemas i have attributes defined. When i use WSCOMPILE, it does not generate proper classes, if the schema is too complex. It has worked only for simple schemas. Is there any other way of doing it?

    Hi!
    If you are using jwsdp 1.6 or earlier and I remember correctly this uses JAXB 1.0 for databinding, which doesnt support all schema constructs.. Even if I'm wrong on that, you could use the -f:nodatabinding option with wscompile and do your own databinding with for example xmlbeans, which supports all schema constructs and is far more flexible than jaxb 1.0 (= personal opinion ;-)
    good luck!

    Hello,
    We do not support any tool in 10.1.2 to create Document Literal WS. you can do it by modifying manually the WSDL and the implementation of the service.
    Another solution would be to use Apache Axis deployed in OracleAS 10.1.2, and when moving to 10.1.3/J2EE 1.4 you can use the WSDL to move the implementation to JAX-RPC using a top down generation.

  • Document/literal web service

    The bets place I would suggest you begin is at http://java.sun.com/webservices/docs/1.6/tutorial/doc/index.html. It's got plenty of information.
    The WSDL would list all the methods available to be used from the Web Service. Once you create an object of the Web Service, you could invoke all the methods provided by the WebService.
