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.

Can use PLSQL to develop PLSQL web services?

Hi,
I know we can use JDeveloper to create PLSQL web services.
How about if we want to develop plsql web services using PLSQL itself, is that possible?
Please advise.
Thank you.

I found the article on how to call web services from within database.
http://www.oracle.com/technology/tech/webservices/htdocs/samples/dbwebservice/DBWebServices_PLSQL.html?_template=/ocom/technology/content/print
The example is for oracle9iR2.
It's looks like it's quite a bit of work compare to use java to call web services. I wonder with Oracle10g database, is there any improvement that will simply the steps? Would appreciate some advice as i don't have oracle10g environment in my place.
Thank you.

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/>

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.

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

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

Need help developing web services on Jdeveloper

Hi,
I'm having some problems developing a particular web service using jdeveloper 10.1.2.1.0 (build 1913).
The web service is located on a remote computer (windows server 2003 SP1), deployed on a jboss3.2.5.
I got the following error:
java.lang.ClassCastException: oracle.xml.parser.v2.XMLText
at oracle.jdeveloper.webservices.runtime.WrappedDocLiteralStub.fromElement(WrappedDocLiteralStub.java:614)
at mypackage1.PdfGenStub.getConfigurationXML(PdfGenStub.java:189)
at mypackage1.PdfGenStub.convertDocumentToPdf(PdfGenStub.java:241)
at mypackage1.PdfGenStub.main(PdfGenStub.java:42)
The web service is from a product that we have that converts documents to pdf.
Any ideas ??
However, I will try to intall the product on another machine that has connection outside the company network to put the WSDL link here for anyone who wants to test it .
thanks

Hi,
Would really help if you could provide the wsdl and also steps to reproduce this exception, for us to try it out locally.
You could also try to install the latest JDev 10.1.3.1 available on OTN, to see if it works on it.

Issue with calling an external web service using web service proxy

Hi,
I've created several web services using JDeveloper succesfully in the past, however I'm getting an issue with one that was working ok previously. Have spoken to the developers of the external web service and they say they haven't changed anything. Also if I test the external web service through soapUI for example it seems fine so it would seem that the issue is with the autogenerated code created by JDeveloper.
Basically I get the following exception as it sends the request to the external service:
java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: Bad Authentication header format: 'Basic realm="Integration Server" encoding="UTF-8"'
Expected "," at position 33
The user name/password appear correct.
JDev version 10.1.3.42.70
Any ideas?
Many Thanks
Gary

Found the answer. Basically I had one proxy web service working and one not both linking to a middle tier written in web methods. THe issue actually ended up being with the web methods code in that the one web service (that was not working) was put together using a backwards compatability mode. Once this was switched back then started working again in JDev.

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!

How to access PL/SQL Web Services using java

New to Webservices. Created PL/SQL Web Service using JDeveloper. Vendor is not sure how to access it using java. Can anyone please help to point in the right direction or provide some sample ?

So if I'm correct you have already exposed a PL/SQL procedure or function as web service?
In that case you can generate a proxy (client) for the generated web service using JDeveloper. It will generate Java code which invokes the web service.
See the wizard in JDeveloper, it should be in the same category as the create PL/SQL web service wizard.

Web services with Jdeveloper using weblogic as server

Hi,
I try to test creating PL/SQL web services by using a connection hosted by weblogic server instead of OC4J. The problem is what I try to publish a package of the database in the second stage when it asks for the connection to use, in the list I don't found the connection I create to weblogic . It presents as choice only connections used the server OC4J.
I do not Know if it is possible to publish a package as web service by using weblogic server connection, and how to do it.
can anyone help me please .

Web services can only be published to BEA if you install Apache SOAP on BEA and use the Apache SOAP option of JDeveloper. The J2EE Web Services implementation framework is specific to Oracle9iAS.
The PL/SQL Web Services server implementation is based on the J2EE Web Services option and as a result is not really portable to BEA.
To publish a PL/SQL Web service on BEA with JDeveloper you would have to write the Java wrapper code to invoke the stored procedure using standard JDBC and then publish that Java class as a Web service using Apache SOAP. Then if you had Apache SOAP installed on BEA you would be set.
Portability of Web services implementations is a big feature coming with JAX-RPC - currently what most vendors have is interoperability between implementations because of things like SOAPBuilders and WS-I. When JAX-RPC becomes part of J2EE 1.4 roughly in June and vendors start putting out implementations on it you should get closer to portability.
In the meantime, the easiest way to get portability is to use the same SOAP server on both servers - Apache SOAP is a good example.
Hope this helps.

How to develop web service using Intellij Idea 6.0

How to develop web services using Intellij Idea 6.x. A sample web service and service client is needed with full procedure. Thanx in advance.

Web service is technology not a tools that bundle with IDE.
For example you can't say how can I develope object orented program with Eclipse.
1- You should get some general info about SOAP, WSDL and Web sevice usage
2- Start to implmenet a simple Hello world web service and deploy it on application(web service) server
3- Write Client code and test it.
for step 2,3 Apache Axis(2) could be a good solution for developement or you can use JAX-WS for sun

How to Create and Deploy Web Services Using Oracle 9i JDeveloper

Hi,
My Question is how to create and deploy Web Services using Oracle 9i JDeveloper.Anybody please give me a detailed Reply.Please Reply to [email protected]
Hopr to Hear From you,

You could use datasources. You should do this in your BC4J Configuration. Then when deploying your applicaiton use the command -installDataSource (from admin.jar) to create the right datasource.
You could probably use the name of your connection + "DS" so you can also use it locally in JDeveloper as JDev seesm to create this automaticly for your Connections.

Problem with CLOB in PLSQL Web Service.

Hi-
I have Oracle Package that accepts CLOB as IN parameter and another CLOB as an OUT parameter. I went thru the tutorial in how to publish a database
PLSQL package as a web service with out any problem. I was able to publish and call successfully my PLSQL web service thru a browser and thru a simple C# application. It's been working fine until I receive an XML file which is bigger than 32766:
java.sql.SQLException: setString can only process strings of less than 32766 chararacters at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:137)]
JDeveloper version: JDeveloper 10g (10.1.2.2.0) Build 1929
Oracle Application Server 10g
I'm newbie in JDeveloper so any help is greatly appreciated.
Thanks!

well Shay,
i've used JDev's tools to developer and to deploy the web service: the war and ear files are automatically generates you to the end of the process.
I have included all the files java and the compiled classes, but I do not have files jar.
But don't works: if i create only one java class with all code inside then it works fine!!
