Creating Web services using JDeveloper for Pl/SQL package having ref cursor

Hi,
I am trying to create web services for PL/SQL package in JDeveloper. When I am trying to create this web service, the functions in the package which is returning referential cursor or record cursor are not visible. When I highlight the function and click "Why Not?", it displays the message "The following types used by the program unit do not have an XML schema mapping and/or serializer Specified: REF CURSOR". Could you please let me know, how I can create this web service?
I am getting similar error when I am trying to create web service for a package with overloaded functions also.
Thanks,

Ok so I played around with this some more. I created the same process in bpel using oracle bpel designer and here are the results.
1. Against 10g database running a synch process data is retutned without error.
2. Against 9i database running an asynch process data is retutned without error.
3. Against 9i database running a synch process data is retutned with error.
I'm definilty missing something.

Creating Web Services using Java Implementation

Hi,
This is quite a general question on how to create a Web Service using Java Implementation that needs to conform to a client XML schema.
Here are my Version specs,
I am using Jdeveloper 10.1.3.4.0 and deploying onto OAS 10.1.3.
I will be creating a J2ee 1.4 (JAX-RPC) Web Service using Document/Wrapped style.
I have been provided an XML schema from the client which is quite complex.
Using a top-down approach, I can create my WSDL file and import the XML Schema for my type definitions.
The Web service aim is to accept some parameters and return some data from the Oracle Database. The
XML response from the web service must conform to the element, attribute definitions in the provided XML schema.
From a Java implementation approach, what is the best (simplest or quickest) way to retrieve data from the Oracle
tables and map each fields/column to the required XML output (defined in the XML schema).
I'm not too concerned with using Java to retrieve data from the Database, more with how I can map the data returned
to the required output. Can this mapping task be controlled within the Java program?
Thanks in advance.

Adding Authentication to Web Service using JDeveloper

Hi Gurus,
I am new to weblogic 10.3 and Jdeveloper 11.1.3. Using Jdeveloper, I imported few packages from database , right clicked and published them as a webservice on a weblogic server. I did not select any WLS policies. The web service is working fine. Now i want to add some basic authorization (username/password) to this webservice.
Which policy should i use ?
Where should i configure this username\password so that all the webservices uses same user for authenctication ? Do i have to create this user on the weblogic server? If yes then how.
Thanks in Advance.
Jack

Hi,
If you are using JAXWS based WebService then you can give it a try:
http://weblogic-wonders.com/weblogic/2010/01/09/username-token-in-jaxws-webservice/
This sample demonstrates ..How we can use UserName/Password Authentication in JAXWS Service. This will be very Easy for you to develop using JDeveloper...U need to Just the add Following XML file as a Policy inside your Application.
Using the following Policy:
<font color=maroon>
<?xml version=”1.0″?>
<wsp:Policy
xmlns:wsp=”http://schemas.xmlsoap.org/ws/2004/09/policy”
xmlns:sp=”http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200512″>
<sp:SupportingTokens>
<wsp:Policy>
<sp:UsernameToken
sp:IncludeToken=”http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200512/IncludeToken/AlwaysToRecipient”>
<wsp:Policy>
<sp:WssUsernameToken10/>
</wsp:Policy>
</sp:UsernameToken>
</wsp:Policy>
</sp:SupportingTokens>
</wsp:Policy>

Hi,
I created the web service using java class then i deployed this web service in to the weblogic admin server.when i tested this process it is working fine.
when I tested The generated WSDL to this process in browser(IE). it is not working.
I need to to invoke this webservice from another BPEL but this WSDL is not working.

Hi,
when i created the webservice in jdeveloper by default it is connected to integrated weblogic server and generates this wsdl.
http://localhost:7101/helloApplication-javaexcel-context-root/MyWebService1Soap12HttpPort?WSDL
then I deployed this webservice in to the Adminserver.it gives the following URL.
http://192.168.56.1:7001/extracExcelToCSV-extractExcelToCSV-context-root/ExtractExcelToCSVSoap12HttpPort?wsdl

Books and resources teaching J2EE 5 (and creating web services using it)

Hi!
I'm starting a new job next week, developing a J2EE 5 system. I have a solid background in J2SE 1.4 and know most of the new syntactical and semantic stuff in J2SE 5.
What I need is a good book teaching J2SE 5 to someone inexperienced with J2SE in general. There isn't a need for me to study J2SE 1.4 as we won't be using it. Also, we will develop some web services using the platform. As time is of the essence I'd prioritize learning about those within the platform, at first.
I don't need to read the entire book in one week, of course. But I need something to study and also have as a reference by my side when programming.
As the offerings in J2SE 5 books seems quite low, I need some advice from you, more experienced people. What book or web resource do you recommend? Thank you for your time reading this post!
Best Regards,
Kent

Hello Kent!
I have found "Enterprise JavaBeans 3.0" by by Richard Monson-Haefel and Bill Burke really interesting. If you have some knowledge about Java EE in general go for it it's really good one!

Develop PLSQL web services using JDeveloper.

Dear Sir,
1. Must we use OC4J to generate PLSQL webservices? or we can use any other J2EE compliant app server?
2. Does it mean in Oracle environment, we can only use JAVA and not other language to wrap PLSQL stored procedures to create PLSQL web services?
Please advise.
Thank you.

You don't need OC4J - you can use JDeveloper to generate Web services from PL/SQL
You can manuall wrap PL/SQL into web services with any language - however JDeveloper uses Java to do this without the need for you to code anything.

Implementation of Asynchronous Web Services using JDeveloper

Various articles and tutorials, which I have read, are talking about asynchronous BPEL processes. These asynch BPEL processes are result of the orchestration of different synch and asynch atomic services (web services in specific). There are even tutorials as part of Oracle SOA Suite and JDeveloper explaining how to consume asynchronous services in a BPEL process. Well and good.
But unfortunately I haven’t seen any tutorial or article talks about the implementation of asynchronous web services (How to implement an asynchronous service?). All what they talk about is the consumption side of it and the applicability of WS-Addressing or Correlation ID for the consumption of the Service.
As part of my research, I delved further into the sample BPEL processes comes out with Oracle BPEL Process Manager. For example; I have had a look into the Asynchronous Loan Processor process, where it is orchestrating a Synch Credit Rating Service and three asynch services namely Star Loan, United Loan and American Loans. But as I delved down into those, I realized that these services are simply BPEL Processes where it is implemented as a sequence of Receive, Assign and Invoke activities, where each of the activities does the following.
Receive -- Receives the request from the client
Assign -- Does some manipulation on the Input variable and set the output variable
Invoke -- Invokes the client back (call back)
These kinds of asynch services are pretty fine to demonstrate theory.
But if we put ourselves more into practical scenarios, where we invoke a service from some application and the result of that invocation shall happen after some time (minutes to hours) in the form of a callback. In that case we WON’T be able to realize the service simply by a simple BPEL Process, rather we will have to implement as a Web Service with two port types implemented, where one port type is for the request and another one for the callback.
I do understand these kinds of services can be implemented using JAX-WS.
Question Here: How I do it using Oracle JDeveloper and Oracle Application Server???
If anyone have done it, the REAL implementation of ASYNCH Web Services *(NOT BY USING BPEL or BPEL Wrapper)* using JDeveloper to deploy on Oracle Application Server or on Oracle SOA Suite, please post the know-how. If someone else is interested in taking it forward, we can take it further together.
-Sudheer
P.S: I am NOT at all interested in theory, as I had enough. Here I don’t want to be Conceptual; rather I am talking about hands-on.

Hi Sudheer,
I am not sure if this will help you
If you take Oracle SOA Suite Order Booking Tutorial and go to Chapter 5 Creating the CreditService Project ( http://download.oracle.com/docs/cd/B31017_01/core.1013/b28937/creditservice.htm ), you learn how to create a synchronous Web service from a WSDL file.
If you take the wsdl and delete output and fault tags (you can see it below) and follow the steps you'll generate an asynchronous web service.
The generated Java method will be a void method
public class ValidateCreditCardImpl {
public void verifyCC(CreditCard creditCard) {
Inside this void method you can try to call to a Receive BPEL Activity.
I hope this will be useful . Regards,
J

Creating Web Services using Netbeans GUI only

Hi all,
Creating, deploying & testing simple web-services through Netbeans point-n-click interface is quite simple (demo at: http://download.java.net/javaee5/screencasts/hello-simple-glassfish/). The demo shows a very simple service creation scenario, accepting and returning String types only. The service can easily be tested using the GUI option 'Test Web Service', which simply test the service through a simple web page at http://localhost:8080/MyWebApplication/MyWebService?Tester
In a similar manner, I am trying to implement a web service (a little complex one, accepting and returning custom types) using Netbeans GUI only. Versioning information I am using are as follows:
NetBeans IDE 6.1
Sun Java System Application Server 9.1_02 (build b04-fcs)
JAX-WS 2.1.3.1
Roughly speaking, the service's method signature I am using is shown below:
public abstract myclass.X MyService.serviceMethod( myclass.X )
Since it uses a custom type in parameter and return-types, the web-based test doesn't work any more. I wrote a separate client class to invoke the service using client-side stub classes (suppose to be generated by JAX-WS generated classes). The client code looks like as follows:
public class ServiceClient {
     public static void main(String[] args) {
          MyService srv = new MyService ().getMyServicePort();
          X xin= new X();
          X xout= srv.serviceMethod( xin );
          System.out.println( "Result: "+ xout.toString());
Netbeans shows a compiler error on "MyService srv = new MyService ().getMyServicePort();
Is it possible to get it resolved without making use of ant scripts for generating client-side artifacts (stubs etc.)?
Thanks,
irfan

Hello Sandy,
Have you installed the Sun Java System App Server or JWSDP? If so, please make sure that one of the libraries in your Netbeans project contains the jaxrpc-api and jaxrpc-impl jars (which seem to be necessary to run wscompile).
Netbeans ("standalone") doesn't seem to install the jaxrpx libraries and other jars required to compile and run webservices.

Jonatan

Creating web services using WAS 6.40

Hello All,
When I try to create one in my WAS 6.40, I always get stuck @ the entry that prompts for the package. The error messgae that I received is "Test objects cannot be created in foreign namespaces". Can someone advise what could be the problem ? Am I missing something here ? My apologies if the questions is too trivial but I am totally new to all this R/3 / ABAP thingy. Thank you.
from
Kwok Wei

Hi Kwok,
There are two solutions for your problem.
first, if you want to make it transportable then create a
package and asign your object to that package, you'll get
Request Number for package and object assigned.
Secondly you can also save it as Local Object.
To read about web services in details visit <a href="http://help.sap.com/saphelp_nw04/helpdata/en/9b/dad1ae3908ee44a5caf57e10918be9/frameset.htm">this</a> and <a href="http://help.sap.com/saphelp_nw04/helpdata/en/D6/F9BC3D52F39D33E10000000A11405A/frameset.htm">this</a>

Integrating Windows Live web service using Jdeveloper

Hi,
We are integrating windows live web service in our oracle portal application. We are trying to create a web service proxy using the URL https://domains.live.com/service/managedomain2.asmx?wsdl. But, we just get an error saying "No WSDL document could be found". Please let me know how to access this web service.
Please note that we are able to access this web service through the browser.
Regards,
MJ

When building the service, there is an option to deploy a stateful service: check the stateful checkbox, in the step 2 of the wizard - Methods definition.
On the client side, you will have to enable HTTP based cookie, so that the client remember the JSESSION cookie.
Hope this helps,
Eric
