Help: Creating web service proxy using JAXB generated domains

Hi,
I'm currently doing some investigation considering the use of web services (BPEL) as a complete application backend.
The application should contain a pojo facade which communicates with some web service proxies. By making a datacontrol
of the pojo facade, I'm able to expose methods to the client layer.
I generated my domain objects by using the JAXB Compilation option in JDeveloper. By using that, a java class can be generated
based on an XSD. Disadvantage of this use, seems to be the fact that the ObjectFactory class, generated by JAXB, is overwritten
each time I create java classes from an XSD.
Q1: Is there a solution to prevent the ObjectFactory class to be overwritten? I also could decide not to use it.
After the domain objects are created, I want to call the actual webservice and receive the response by using the JAXB marshaller
and unmarshaller. Problem here is:
Q2: How do I (manually?) create a proxy which calls the web service, by using the domain objects generated by JAXB?
Q3: An important requirement is that it needs to be simple to switch from several environments (eg from development to test). How
can I fulfill this requirement in a nice, solid solution?
Any tips working with web services as the backend layer are welcome!

Errors creating a Web Service Proxy using Microsoft WSDL.exe tool

I have deployed a BPEL process using JDeveloper. This process can be invoked from the BPEL console and completes as expected. I am trying to create a Web Service Proxy using the Microsoft WSDL.exe tool so that the process can be invoked from a Microsoft Word document. This process is based on the AutoLoan example in the Developer's Guide for Microsoft Office Interoperability B25781-01.
WSDL.exe returns the following error message
Error: There was an error processing 'http://erp.template.co.uk:8889/orabpel/default/HonorariumSmartDoc/1.0/HonorariumSmartDoc?wsdl'.
- The document at the url http://erp.template.co.uk:8889/orabpel/default/HonorariumSmartDoc/1.0/HonorariumSmartDoc?wsdl was not recognized as a known document type. The error message from each known type may help you fix the problem:
- Report from 'WSDL Document' is 'There is an error in XML document (19, 7).'.
- A schema with the namespace '' has already been added.
- Report from 'DISCO Document' is 'Discovery document at the URL http://erp.template.co.uk:8889/orabpel/default/HonorariumSmartDoc/1.0/HonorariumSmartDoc?wsdl could not be found.'.
- The document format is not recognized.
- Report from 'XML Schema' is 'Expected Schema root. Make sure that the root element is <schema> and the namespace is 'http://www.w3.org/2001/XMLSchema' for an XSD schema or 'urn:schemas-microsoft-com:xml-data' for an XDR schema. An error occurred at , (2, 2).'.
How do I resolve this error?

The WSDL file is below.

Deployment is failing on creating web service proxy in portlet.

Hi All,
I am using a JDeveloper 11.1.1.2.0.
1) I have created a application (portlet producer application), which contains few jsf pages (not jspx).
2) I have added a web service proxy ( using New>Business tier>Web services>web service proxy, provided a wsdl) for accesing a service which is exposed on different server.
The above combination works perfectly fine.
But When I convert the JSF pages to portlet (right click on JSF page and select create portlet entry option), and tried to run it throws following error.
Note: soainvgpkg is the package which is generated when I create a web service proxy.
It is generated under application resources.

It works fine if I again remove the portlet entry and delete the portlet.xml and oracle-portlet.xml which were generated during portlet conversion time which is nothing but a normal JSf application.
Please help,

Hi,
It might be that the .net service which you have is not WS-I compliant. Can you first run WS-I Analyzer on the wsdl to see it the test passes.

How to create Web service proxy in Eclipse?

Hi,
I want to create web service proxy in Eclipse. Can someone tell me what all plug ins are needed for it and what is the detail procedure for the same?
Thanks in advance.

Proxy class is out of date now... proxy class only support stateful web service call... and stateful web service may became a big limitation in development.
Try to thinking about how to use stateless web service call, you may get an alternative solution.

Error creating web service proxy for bpel process in jdev 10.1.3

Hi,
I am trying to create a web service proxy in Jdeveloper 10.1.3, and get the following error:
Element type "fault" is missing required attribute "name"
I have created a fault on one of the operations, and in the .wsdl file there is a name attribute:
<operation name="process">
<fault name="TestError" message="client:TestErrorMessage"/>
</operation>
The fault definition in the .wsdl obtained from the process when you access it over http is somewhat different:
<fault>
<soap:fault name="TestError" use="literal" encodingStyle="" />
</fault>
Any ideas how to workaround this problem?

Hi Yatan
The error is mostly there may be some Duplicate variable/schema element decalared in the wsdl or the xsd referred in the wsdl. Like in WSDL for any Operations, most of the times, we use input and outputs as complex xsd element. We declare these xsd in the same file or in another file and import that in the .wsdl file. So check or validate your XSD file for any Duplicates.
In JDeveloper itself, I think, you can open XSD or WSDL and validate it from right click menu options like that.
Thanks

Creating Web Service Proxy From WSDL - Error SPRX046

We are attempting to create some Web Service proxy objects from some WSDL files. Some of the WSDL files contain message definitions with multiple parts such as
<i><wsdl:message name="GetNewSubmissionsResponse">
      <wsdl:part element="impl:Count" name="Count"/>
      <wsdl:part element="impl:MoreAvailable"       name="MoreAvailable"/>
      <wsdl:part element="impl:IRSData" name="IRSData"/>
      <wsdl:part element="impl:StateSubmissions" name="StateSubmissions"/>
   </wsdl:message></i>
This always generates the error message <b>SPRX046 - "
Msg Proxy generation terminated: Message must have exactly one part".</b>
Is this just a limitation with SAP Web AS? Has anyone dealt with this before? These WSDLs work in other environments (AXIS Java, XML Spy etc).
Thanks

It seems ABAP proxy only supports Document-Literal style WSDL. Document-literal style is supported by most Web services platforms, and is supposed to be most interoperable.
Per WS-I Basic Profile 1.0 (see [1])which provides interoperability guidance of using WSDL1.1, when the message part is defined using the @element attribute, the message can only be bound to so-called "document-Literal" style which in turn requires that the message contains only one part.The WSDL you provided violated the document-literal rules.
Have you tried to change the message definition a bit so it's BP conformant? Try defining a complex type for the subelements, then define an wrapper element to use that complex type, and finally let the message part to refer to the wrapper element. Something like,
<wsdl:message name="GetNewSubmissionsResponse">
<wsdl:part element="impl:GetNewSubmissionsResponseWrapper" name="myResponse"/>
</wsdl:message>

Issue with creating Web Service Client using Oracle JDeveloper

Hi All,
I am trying to create a Web Service Client using Oracle JDeveloper. I set the Project compiler property to JRE 1.4
When I run the web service client, it throws me bunch of errors saying:
'Error(32,2): annotations are not supported in -source 1.4'
I am wondering why JDeveloper is using annotations even after I set the compiler property to 1.4
I am following this link to create the webservice client:
http://www.oracle.com/technetwork/developer-tools/forms/webservices-forms-11g-094111.html
Any help in this regard would be greatly appreciated.
Thanks,
Scott.

Dear Shay,
Thanks for your prompt response.
You are right. JDeveloper 11g uses JDK 6 style annotations for the clients it creates. But you can change the JRE Version used at compile time by following these steps:
1. In the Applications Navigator, right-click the Project Nanem node and select Project Properties... from the context menu.
2. Select the Compiler node and check the Source Files and Generated Class Files dropdown lists. You may change these versions depending on the version of the JRE you are using with Forms to ensure that the compiled
classes from JDeveloper can be read by the JRE used by Form.
So I selected JDK version 1.4 there.
Sorry that I did not mention that we are using Oracle Forms 10g. That is the reason I selected JDK 1.4
Thank you.
Scott.
