Jdev web service and SOAP header

Hello,
How can I implement a web service in jdev that extracts some elements from the SOAP header ?
How can I implement a web service proxy in jdev so that it inserts elements in SOAP header?
Thank you.
The operation WSDL looks approx like this:
          <operation name="SoapDDXML">
               <soap:operation soapAction="someaction"/>
               <input>
                    <soap:body
                         use="encoded"
                         namespace="ns"
                         encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
                         parts="psXML"/>
               </input>
               <output>
<soap:Header>
<OurCredentials xmlns="ns">
<UserName>string</UserName>
<Password>string</Password>
</OurCredentials>
</soap:Header>
                    <soap:body
                         use="encoded"
                         namespace="ns"
                         encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
                         parts="Result"/>
               </output>
          </operation>

Hello,
When using OracleAS/JDeveloper 10.1.3.x you are creating Web Service using the standard JAX-RPC API. This API uses the SOAP with Attachments API for Java (SAAJ) to manipulate SOAP messages.
When dealing with SOAP Header, it is common usage to use the notion of "handler" to set/read header from the messages.
The chapter "Using JAX-RPC Handler" is a good point to start to see how do deal with this requirement,
When manipulating the header in the handler, the code will look like:
SOAPHeader header = message.getSOAPHeader();
Name headerName = soapFactory.createName("OurCredentials", "ns", "http://schemas.xmlsoap.org/soap/encoding/");
.. // add sub element
SOAPHeaderElement headerElement = header.addHeaderElement(headerName);also..
Could you specify the version of JDeveloper and the type of Web Service that you are using when ascking a question on the forum it help community member to provide a better answer.

  • Generating Web Service with SOAP Header

    Hello,
    I have a WSDL for a web Service using document encoding and with a soap header.
    I generate a jws file using WL Workshop 81.SP4 but I always have this error message :
    ERROR: AjoutContactService.jws:13: The binding for AjoutContact does not declare one part.
    ERROR:      SUGGESTION: A document literal binding must have at most one part. Make sure you have a WSDL that declares just one part for each message with a document literal binding.
    The header is a recent adding on an existing Web Service, and I can't change the wsdl definition. I also need to use data contained by the header in conjunction with data in the body.
    Is it a limitation with workshop or a problem with with my binding file ?
    I give sample of my two wsdl files.
    Given wsdl file
         <wsdl:message name="inputAjoutContact">

    Hi,
    This appears to be a known limitation and is addressed by CR227689
    which has a workaround that needs the wsdl to be modified.
    I am not sure if this is possible given that we don't control the wsdl most times.
    Could you please open a BEA support case and refer to CR227689?
    Vimala-
    p.s:
    I found some info on the issue which could help:
    1) Refer to <http://lists.oasis-open.org/archives/regrep/200306/msg00071.html>
    you will see that only one part is allowed in the message part for doc/literal webservices Snippet from the above link
    "Also, keep in mind that WS-I BP permits only one <part> on document/literal messages, so to be WS-I compliant, you would have to include it in the message structure. "
    2) Refer to http://www.ws-i.org/Profiles/Basic/2003-08/BasicProfile-1.0a.html#refinement35722968 <http://www.ws-i.org/Profiles/Basic/2003-08/BasicProfile-1.0a.html>
    below R2208)
    "For document-literal bindings, the Profile requires that at most one part, abstractly defined with the element attribute, be serialized into the soap:Body element."
    This implies Soap body contains message which contains a at most one part.

  • Calling Web Service with SOAP header from BPEL

    Hi,
    I am calling a web service (with header information) from BPEL. In the Invoke activity, i created a header variable to pass the header information.
    But, when i test the BPEL service, invoke activity fails because the header information is not being passed.

  • Split/Join, Invoke Service and SOAP Header in osb10.3 wls10.3

    Hi gurus,
    Are Split/Join able to invoke external services with a custom SOAP header?
    I have a split join to call 2 external business services in parallel. Those 2 external services requires a custom SOAP Header
    <soapenv:Header>
    <v1:ConsumerRequestHeader>
    <v1:requestSessionID>TEST_1</v1:requestSessionID>
    <v1:requestTimestamp>2011-06-16T16:57:54.943+02:00</v1:requestTimestamp>
    </v1:ConsumerRequestHeader>
    </soapenv:Header>
    All WSDLs were configured by the instructions of this link : http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/eclipsehelp/tasks.html#wp1150628, but in my debuging, the SOAP header is disappeared when calling those external services from the splitjoin. (No problem if designing and testing with the ProxyService. but Proxyservice is useless here because of parallel processing)
    When designing with OSB Workshop IDE, there is no way to pass the custom SOAP header to the "Invoke Service", only the body request/response message.
    My question is, Split/Join automatically uses its header to pass it into the invoke call ?
    Please advise...
    Thanks,

    see this :https://forums.oracle.com/thread/951618
    not the most fancy way, but you can create some sort of  wrapper proxyservice in front of your business service to make it work

  • Java Web Service Access SOP Header and SOAP Body

    Hi
    I am newbie to Web Service. I had a Java class and I converted it to Web Service(LoginWebService has methods login, register).
    Now my client is accessing my web services and calling methods login and register.
    Now I want to add few values in SOAP header in client side.
    My Questions:
    1. How can I access the SOAP headers and SOAP Body in my Server Web Service method implementations?
    2. Is there any API that I have to use?
    3. Does anyone have any sample code for these things?

  • Diff b/w Web service and window service

    What is the difference between web service and window service, whether the both are same or not, Give some explain about that each one and give some examples also.

    An XML Web service is a component that implements program
    logic and provides functionality for diseparate
    applications. These applications use standard protocols,
    such as HTTP, XML, and SOAP, to access the functionality.
    XML Web services use XML-based messaging to send and
    receive data, which enables heterogeneous applications to
    interoperate with each other. You can use XML Web services
    to integrate applications that are written in different
    programming languages and deployed on different platforms.
    In addition, you can deploy XML Web services within an
    intranet as well as on the Internet. While the Internet
    brings users closer to organizations, XML Web services
    allow organizations to integrate their applications.
    A Windows service starts much before any user logs in to
    the system (if it has been setup to start at boot up
    process). A Windows service can also be setup in such a way
    that it requires a user to start it manually ? the ultimate
    customization!
    Windows services run as background processes. These
    applications do not have a user interface, which makes them
    ideal for tasks that do not require any user interaction.
    You can install a Windows service on any server or computer
    that is running Windows 2000, Windows XP, or Windows NT.
    You can also specify a Windows service to run in the
    security context of a specific user account that is
    different from the logged on user account or the default
    computer account. For example, you can create a Windows
    service to monitor performance counter data and react to
    threshold values in a database.

    Hi Mou,

    The error message I quoted from Fiddler:

    I am not totally sure that error occurred by the authentication. But I suggest you can try to add this service into your project using this method below:
    1.right click the Reference and select Add Service Reference
    2.input your service link and click "Go"
    And you can use this service as the following:
    private async void callService()
    ServiceReference1.SearchDataIndexSoapClient client =new ServiceReference1.SearchDataIndexSoapClient();
    var Str= await client.StartIndexAsync(new ServiceReference1.AuthHeader { Username = "Admin", Password = "Admin" });
    Please try it.

  • SQL Server 2008 Reporting Project - Invoke/Consume Web Service and Return Dataset in C# Code-Behind

    Hello,
    I have a Visual Studio 2010 C# class with a method that invokes/consumes a web service and returns an XML dataset. I am traversing through the parent/child nodes and parsing out the data then inserting it into a SQL Server 2008 R2 table for a join within
    another stored procedure. 
    Instead of using a 3rd party API to generate the PDF for this data, I am creating an SSRS report. The formatting will be easier and I can do a RenderFormat directly to PDF.
    Can I expect to be able to transfer the code-behind method to this report and have it be able to work with the web service the same way? It is a SOAP-based web service returning parent nodes and two levels of nested child nodes.
    I have also been researching the approach of calling the web service in the same stored procedure that is currently querying the physical tables (which is used to populate a gridview and PDF) but it looks like it may only be possible with a CLR stored procedure.
    Is it possible to implement a CLR stored procedure within an SSRS report? 
    Hope this makes sense. Any help, suggestion or point in the right direction would be greatly appreciated.
    Thanks,
    Buster

    Hi Buster,
    SSRS supports web service data source, we can call the SOAP-based web service in SSRS report directly. Then, we can use custom code in SSRS to parse the XML data. However, we won’t be able to join another data in SQL Server database.
    Reference:http://technet.microsoft.com/en-us/library/aa964129(v=sql.90).aspx#repservxmlds_topic3
    We cannot implement a CLR stored procedure within an SSRS report directly. In order to execute the CLR store procedure in a SSRS report, we have to execute it as text using the following code:
    Exec <stored procedure name>
    Reference:
    http://dotnetslackers.com/Community/blogs/bmains/archive/2009/01/15/executing-a-clr-stored-procedure-in-reporting-services.aspx

  • Deploying a VB dll using some web service and accessing it through java

    I'm new to Web Services Based Programming. I would like to know whether this is possible and if so has anyone tried it. I want to create a vb dll that contains the remote methods that the client will access from a java program. After going thru a lot of articles, I'm still unsure on how to do this. I found one method was to Create a VB program/dll, deploy it in a web service and create the java program that accesses by another web service.
    I'm doing this as part of my lab syllabus. The thing is My lab exercises do not state anything about the technologies that I can use to do this.
    This is all that is stated there:-
    Creation Of DLL Using VB And Deploy it in Java
    I just cant get any ideas other than deploying both the parts as web services. If anyone has Better ideas for this, I would really appreciate it.
    I dont know anything about CORBA for languages other than Java and I'm already using the servlets and EJB's in my normal life. I'm also learning the ORB based programming in java. Therefore your help will probably help me learn something new then what I know.

    Sorry I wasn't too specific in my last question.
    This is my java class calling the native method print
    //HeyWorld.java
    class HeyWorld {
    private native void print();
    public static void main(String[] args) {
    new HeyWorld().print();
    static {
    System.loadLibrary("HeyWorld");
    In this case, my C method for calling a C++ method: HelloWorld.cpp
    #include "jni.h"
    #include "stdio.h"
    #include "stdafx.h"
    #Include "HeyWorld.h" //this is where i get my function prototype
    #include "Test.h" //this is the C++ header where the print method and the Test class is
    JNIEXPORT void JNICALL
    Java_HeyWorld_print(JNIEnv *env, jobject obj)
    CTest a; //CTest is the print class I created
    a.print();
    //This is the header for Test.h
    class CTest: public CWinApp
    public:
         CTest(); //constructor
         void print(); //our method
    //And this is the implementation of the class Test.cpp
    void CTest::print()
         printf("Hey World!\n");
         return ;
    I could compile the Test.cpp, HeyWorld.cpp successfully. However when I tried to compile HeyWorld.cpp using
    cl -I<path of jdk include> -I<path of jdk include win32> -LD HeyWorld.cpp -FeHeyWorld.dll,
    the VC++ 6.0 compiler gave me this error:
    HeyWorld.obj:error LNK2001: unresolved external symbol "public:_thiscall CTest::CTest(void)"
    HeyWorld.obj:error LNK2001: unresolved external symbol "public:_thiscall CTest::print(void)"
    Thanks for the help.

  • Web Services and JHS

    My company is exploring the use of JHeadstart and we are very impressed with its capabilities. The enterprise environment into which our system will be deployed requires separation between the View Layer, and the Model Layer, with a SOAP-based messaging agent as the go-between (it's MQ series-based). We have been able to get a prototype plain-old UIX application to work where we deploy the Application Module in the Model project as a web service, and then create a data control from the stub to consume in the UIX ViewController project. We can then simply drag and drop the Web Service call result sets onto the UIX pages. However, when trying to do this with JHeadstart, the Wizard for creating Application Structure Files requests an Application Module on one of the first screens. In our environment, we won't be able to allow the ViewController project to see the Model project. Is there any way to use a web service instead of the Application Module? If not, is there any plan to support this type of activity in a future JHS release?
    Thanks in advance,
    Dan Schiff

    Dan,
    Currently JHeadstart only supports ADF Business Components as the Business Service layer (directly accessed, not through a Web Service wrapper). As you found out, ADF supports other Business Services as well, not only Web Services but also TopLink, EJB, etc.
    JHeadstart is primarily intended for data manipulation (select, insert, update, delete) and our philosophy is that that type of functionality (that part of your application) is most efficiently handled directly by ADF Business Components. Also, this is the most productive technique for application developers. Of course, the end result of generating an application with JHeadstart is that you have a "normal" ADF application, to which you can add Web Service functionality with the normal JDeveloper visual editors and drag-and-drop features.
    So you could generate efficient data manipulation screens using JHeadstart and direct ADF Business Components, and then add interoperability with other Business Services to your application using Web Services. The latter part is not JHeadstart-generated.
    The next JHeadstart release (10.1.3) will be focused on supporting JSF (JavaServer Faces). We are also looking into support for other Business Services like TopLink, but we don't have any schedule for that yet.
    kind regards,

  • Web services and EJB3 @resource annotation

    This block of code works fine when NetworkViewBean is left as a @Stateless session bean.
    Once I have JDeveloper 10.1.3 production expose it as a web service, I can no longer call the Entity Manager @Resource.
    I always get a java.lang.NullPointerException returned.
    Any ideas?? thanks for your help!
    @WebService(name = "NetworkViewWS", serviceName = "NetworkViewWS")
    public class NetworkViewBean {
    @Resource
    private EntityManager em;
    public NetworkViewBean() { }
    public String getDeviceVendorModel(String name) {
    if (name == null || name.length()== 0) return "Null Input Parameter Specified";
    NetDevice N= null;
    try {
    N= (NetDevice)em.createNamedQuery("findByDeviceName").setParameter(0, name).getSingleResult();
    catch(Exception E) { E.printStackTrace();  return null; }
    return "Vendor= "+ N.getVendor()+ ", Model= "+ N.getModelNumber();

    Hi Joshua,
    The problem is that you are using a regular Java web service and in 10.1.3.0.0 we do not have support for dependency injection in the container in the web container i.e. you cannot use annotations such as EJB, Resource in any classes in the web container.
    You have two options:
    1. Lookup an EJB from regular Java web service (JSR-181)
    or
    2. Make your Web service as a EJB 3.0 web service
    Here what you can do to create an EJB 3.0 web service from JDev
    1. Create an EJB 3.0 Session bean with remote interface
    2. Change your remote interface to a web service end-point change @Remote to @WebService (import javax.jws.WebService)
    3. You do not have to use @WebMethod, we automatically expose all methods in the end-point interface in the web service
    4. You can inject EJB using @EJB
    5. Create a deployment profile for the EJB-jar and deploy the ejb-jar and the EJB will be exposed as a web service. The context-uri for the web service will be /ejb-jarName
    Hope this helps!
