XML DB as a web service provider

Does anyone know where I can find some info/sample programs that use XML DB as a web service provider. I'd like to start publishing PL/SQL packages as web services and can't seem to find anything other than high-level info.
Thanks for any responses.

Just to note, I'm on 10.2.0.1.

ABAP calling web service provided by AXIS -error

Hello expert,
I am calling web service provided by AXIS in ABAP but error occur when processing response part.
The web service is used to create material master in JAVA AXIS system.
After setting up the LP in soamanager then make a call, we got an error saying
"GENERAL_ERROR Error duing proxy processing (PART

I looked at the full trace in soamanger, the call is executed successful, and the data are inserted in the remote system.

For me it looks it is an issue in the response payload that ABAP proxy can not process it.
such as, the response payload NS prefix is soapenv, other than soap-env in request payload...
but i am not sure, whether this is the root cause.
Could you help me to find out what is going wrong here?

Cai Lin

the response payload NS prefix is soapenv, other than soap-env in request payload
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" is equivalent to xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/" . Namespace defined correctly.
I can also see that response is correct (assuming "S" denote success):
<CreateITEMReturn>S</CreateITEMReturn>
Also check type of WSDL style usually this error occurs if you are using RPC/Encoded style WSDL, modify wsdl for Document/Literal style (as RPC style WSDL not supported by ABAP proxy), see this discussion here: Cleint Proxy error

Database as Web Services Provider?

Hello!
Would you please forgive me my silly question but...
My customer has purchased and is using Oracle RDBMS 10g.
Now the customer wants the database to be accessible by web services clients.
The customer thinks that this can be done with already purchased RDBMS (without Oracle's Application Server). The customer cites Oracle: "Database as Web Services Provider: Database operations and data retrieval are executed through Web Services mechanisms" (http://www.oracle.com/technology/tech/webservices/database.html).
However, in my honest opinion the customer MUST install some web server. if the customer is especially insterested in Oracle's solutions, then it has to (additionally to already purchased RDBMS) buy either Oracle Application Server or WebLogic.
Who is right?
Sincerely Yours,
Michail

Michail,
For DB 10g, you are right - the solution is to use PL/SQL Web Services for which an OracleAS/OC4J server is essential.
For DB 11g, both you & your customer are right. In addition to the above like 10g, there is a new feature in 11g called Native XML DB Web Services within the DB which does not require any Web Server or AS. See http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28369/xdb_web_services.htm

Is crossdomain.xml Needed for SOAP Web Services?

A Flash developer who is attempting to use Flash to access a
SOAP web service provided on one of our servers says we need to add
a crossdomain.xml file to our server listing their domain as an
acceptable source. The SOAP service simply accepts some data and
returns a status. It doesn't make sense to me that we would need to
provide a crossdomain.xml file. If we did, all web services all
over the Internet would have to do the same to allow Flash to call
them.
If I am correct and the file is not necessary, then what else
in FlashPlayer might be blocking their attempts to access our
server? I don't know much about Flash, but I do know some sort of
security configuration files are necessary to allow SWF files to
access the Internet. Could this be what they are missing?

Yes, you need a crossdomain.xml file in place. When I do SOAP
calls to
a service not under my control I just write a proxy for it,
then I don't
need to have anyone add the crossdomain policy file.

The format of XML file returned from web service

Hi everyone,
My web service (build in asp.net 2.0 with C#) returns the
following xml file which is not what I want.
<Root>
<Root2>
<Person> .... </Person>
<Person> .... </Person>
<Person> .... </Person>
</Root2>
</Root>
But I want my web service to return the following xml file.
How can I get the following xml file instead of the above xml file
? Thanks.
<Root>
<Person> .... </Person>
<Person> .... </Person>
<Person> .... </Person>
</Root>

Thanks for everyone's reply!
Sorry, I don't know where to set resultFormat="e4x". Below is
my code. And LINE 111 gives error. And the error message is below.
And the xml returned from the web service is below.

SOAP vs. XML-RPC for synchronous Web Services applications

Using existing Application Modules Entities in web service provider

Hi, I want to implement a web service provider having a WSDL file and using JAXWS.
Is it possible to use in input methods of the service, an Application Module or Entities or View Objects that exist in a separate project.
I want to perform database operations and facilitate transactions using existing ORM mapping of ADF.
Thanks,
Ilias Stavrakis

Yes, it is possible, but you have to checkout and release the ApplicationModules manually. Use the method <tt>Configuration.createRootApplicationModule(...)</tt> of the class <tt>oracle.jbo.client.Configuration</tt> to checkout modules, and use the method <tt>Configuration.releaseRootApplicationModule(...)</tt> to release it back to the AM pool at the end of processing.
See this blog entry http://jobinesh.blogspot.com/2010/04/invoking-applicationmodule-from-servlet.html despite the fact that it is not directly related to Web services.

How to consume a web service provided by third party system from SAP system

Hi Friends,
Could any of you provide me a clear picture on how to consume a web service from SAP system and is provided by a third party system?
Do we get an URL to create a client proxy for consuming the web service?
Thanx in advance,
Ram

Hi Ram,
of course you cannot supply the WSDL URL. Inside the WSDL (just view it in your browser) you find (usually but not necessary) towards the end something like
<soap:address location="http://www.weather.gov/forecasts/xml/SOAP_server/ndfdXMLserver.php"/>
which is the actual adress of the service.
An example service can be found here:
<a href="http://www.weather.gov/xml/">National Digital Forecast Database</a>
containing the WSDL URL at
<a href="http://www.weather.gov/forecasts/xml/DWMLgen/wsdl/ndfdXML.wsdl">this address</a>.
You might also want to browse for the amazon webservices which allow you to embed queries against amazon into your application.
have fun,
anton

How to use RESTful Web Services provided from BO Enterprise

Hi Experts,
i am trying to use the Web Service "BIPLATFORM" provided by BusinessObjects Enterprise. As I have trouble reading the WSDL i tried to use the REST interface.
Unfortunatally I cannot find any Docu about that in the internet.
Does anybody have experience in using the BIPLATFORM web service?
Thank you in advance

Thank you very much for your instant answer and help!
I got it now: "no rest in biplatform service"
What made me think REST is possible was only the following entry in ...\webapps\dswsbobje\WEB-INF\conf\axis2.xml
"
- 
- 
- 
- 
- 
<parameter name="disableREST" locked="true">false</parameter>
- 
Anyway I was only hoping to get REST work as the WSDL provided by BusinessObjects Enterprise is not valid to be parsed by SAP Netweaver ABAP SOAP Runtime...
I regret but i have to add: The fact that the web service is only meant to work with certain consumers shows that the people responsible have little to no understanding what the idea of SOAP, SOA and WSDL really is. On the one hand SAP was always pushing their ESOA idea but on the other hand we got this strange limitations like "only for these clients..."
This is exactly the opposite of the SOAP-idea:
"The framework has been designed to be independent of any particular programming model and other implementation specific semantics." - http://www.w3.org/TR/2007/REC-soap12-part1-20070427/

Get xml data from a web service into Forms?

Hello folks! I am reading active directory info from a web service into forms via imported java classes. I can read from functions that return strings just fine, but I have to get the output from getGroupUsers which returns an XmlDataDocument. How do I read this in and parse it in Forms?
I will be grateful if y'all could point me to an example.
Thank you,
Gary
P.S. Here is a snippet of how I get the full name by passing an ID:
DECLARE
jo ora_java.jobject;
rv varchar2(100);
BEGIN
jo := ADSoapClient.new;
rv := ADSoapClient.getUserName(jo, 'user_ID');
:block3.fullname := rv;

Hello,
Since you are already dealing with server-side JAVA, I would suggest you create a method that would do the parsing server-side and what your PL/SQL will be dealing with is just the return string.
Here is a method I use to read an XML file (actually, it is an Oracle Reports file converted to XML) and from the string version, I will do search, replace and other things.
So, from getGroupUsers which returns an XmlDataDocument, you can adapt this method to get your data server-side and let the form module read the output data.
<blockquote>
private String processFileXml(String fileName, int iFile) throws ParserConfigurationException, SAXException,
IOException, XPathExpressionException{
try{
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
domFactory.setNamespaceAware(true);
InputStream inputStream = new FileInputStream(new File(fileName));
DocumentBuilder builder = domFactory.newDocumentBuilder();
Document doc = builder.parse(inputStream);
StringWriter stw = new StringWriter();
Transformer serializer = TransformerFactory.newInstance().newTransformer();
serializer.transform(new DOMSource(doc), new StreamResult(stw));
return stw.toString();
catch (Exception e){
System.err.println(e);
System.exit(0);
return "OK";
</blockquote>
Let me know if this is of nay help.
Thanks.

Reading an xml file in the web services java file

I want to read some data in the webservices file.so i am writing my own xml file through which i want to read data.but i am not able to read xml file from web services file.also , i am not able to put xml file in the .ear file,as there is no such tag in servicegen script through which i can add xml file in the .ear file.
i know in case of servlets,i will specify context-param attributes in web.xml,and i can access those in my servlet.can i do anything like this for webservices,and i am not using any servlets for web services.
kindly tell any solution.

One possible option to parse an xml-file to a flex XML object:
public function parseConXML(source:String):void
                xmlLoader = new URLLoader();
                xmlLoader.load(new URLRequest(source));
                  // Eventlistener: if URL loaded --> onLoadComplete function
                  xmlLoader.addEventListener(Event.COMPLETE, xmlLoadComplete);
            public function xmlLoadComplete(evt:Event):void{
                var xml:XML = new XML();
                 // ignore comments in XML-File
                XML.ignoreComments = true;
                   //ignore whitespaces in XML-File
                 XML.ignoreWhitespace = true;
                // XML-Objekt erstellen
                xml = new XML(evt.target.data);
               //AFTERWARDS use your xml as your wish

I didn't quite get what the problem is but if the the desired file is in custom directory why don't you just use absolute path to reference it?
Like: "/home/my/OSconfig/MConfig.xml"

Client proxy consuming web service provider using logical port issue

Hi All,
I have a proxy client having a logical port (configured using NWDS) to consume a web service in the provider system.
In the logical port, I have given target address, and logical port name. While moving this client proxy NWDI dev track to Q and prod,
how do I change this target address to point to Q and prod respectively. In other words, even though I am using Visual admin to configure the destination url for the logical port, to point to Q and prod, its still referring to the dev environment provider service after moving the proxy client to Q and prod. What is the suggested approach to take care of this issue
Thx
mike

Hi Michael,
I can only help from that point of view that I believe this question belongs to the forum
Service-Oriented Architecture (SOA) and SAP
Please try to raise this question there.
