Can we create a Web Service from a Business Object??

Hello All,
Has anyone created a Web Service using a Business Object?
When I am trying to create a Web Service in TM box, I can see that couple of options like Business Objects, Process Agents are disabled and rest like Consumer Group, Service Provider are enabled. Any idea why this is happening. Is this related to some configuration setting.
Regards,
Abhishek

please elaborate in which environment or case you are creating Web Service from Business Object.As per my understanding we generally create web service through Wizard.
Thanks

SAP Cloud Application Studio Create Custom Web Service From Custom Business Object and Consume in External System

Hi Experts,
I have requirement to create custom business object and create Web Service for that and use in external system (SAP ECC / SAP CRM / Third Party).
1) Is it possible to create custom object web service and used in external system ?
2) When we create the Web service from custom business object what the necessary steps(action : Create , Read , Update) require?
3) Sample Scenario :
My Custom Business Object
businessobject Custom_Integration {
element EP_VAL1 : LANGUAGEINDEPENDENT_MEDIUM_Text;
element EP_VAL2 : LANGUAGEINDEPENDENT_MEDIUM_Text;
element IP_RES : LANGUAGEINDEPENDENT_MEDIUM_Text;
I have created the Web Service using this custom business object.
3) How i can use this web service in external system? what are the prerequisite steps in external system to consume this service in it?
Please anyone have idea about this how to do this and how to achieve this using SDK and custom business object.
Many Thanks

Hello Mithun,
Does this section in the documentation help you:
SAP Cloud Applications Studio Help -> Developers Desktop -> Web Services
The entry "Task -> Create a Web Service" describes how to create a Web Service on your own BO
The entry "Task -> Test a Web Service" helps you how you can use it in a foreign tool / application.

How can I create a web Service from my Web Dynpro Application ?

Hi,
Kindly let me know How I could create a "Web Service" with my Web Dynpro DC project.
Awaiting your responses.
Regards,
Mahesh

Hi Mahesh,
You can use the web services by creating the Model in web Dynpro
And if you want to publish your own web service then you have to create a EJB module and publish as a web service.

WLI: Can't call synchronous web services from async business process?

I have three web services, X, Y, and Z, that I want to call from a business process B. X is asynchronous, Y and Z are synchronous. Therefore, B must be asynchronous. B is called from another business process, A, that must be synchronous. So, I have A call B synchronously using the SyncAsync pattern described in "Best Practices for Oracle WebLogic Integration Application Life Cycle". This worked fine in earlier development when I was only calling X from B. However, when I try to add synchronous calls to Y or Z and run A, I get the following error message from B:
com.bea.control.classic.ServiceControlException: Attempting to perform the client
callback 'doY' while servicing a blocking request from the same client. This can
result in a deadlock condition. An @jws:message-buffer tag should be placed on
the synchronous operation or on this callback.This is obviously an old error message, since it recommends an annotation in the old style. Anyway, what can I do? Shouldn't it be possible to invoke web services synchronously from process B? If so, then how? I don't know what synchronous operation it's talking about -- is it A's call to B? As for the callback, I don't see a separate callback. Annotating the SBControl's method with weblogic.jws.MessageBuffer did no good, and I can't use com.bea.control.annotations.MessageBuffer because the method doesn't return void. Can I make this work without rewriting B, and if so, how? It'd be nice if I could call X, and then call Y and Z while waiting for X's callback.
Alternatively, I could rewrite my processes so that A calls a new process C synchronously, which in turn calls B (which calls X), Y, and Z. That should work, right? Thanks for any help y'all can give me.

Greetings everyone,
We have found a solution to this problem, and it is very much like one offered by Trinidad, except there was some confusion in my understanding.
http://sql-patch/B1WS/webreferences/LoginService.wsdl
Indeed, the url http://localhost/Service.asmx appears in the WSDL files, as well as the web.config.
I changed it to http://sql-patch/B1WS/webreferences/LoginService.wsdl in the WSDL files only. This did not work.
We then found it in the web.config file also, and changed it to http://sql-patch/B1WS/webreferences/LoginService.wsdl also.
The reason I was using this URL is because the files exist there. Looking at IIS, there is no Service.asmx anywhere in the B1WS path, and this confused me.
This got us one step further, but now a new error was showing itself -- 405 Method Not Allowed.
It turns out that the URL we needed to change it to is this:
http://sql-patch/B1WS/Service.asmx
That is, we replace localhost with the name of the machine, and NOTHING else.
This seems to have solved it for us, and is hopefully useful for you.
Thanks all,
Mike

Parse errors while creating a Web service from Java class!

Can anybody tell me please, is it possible to create a Web Service from java class where the input from user is required ?
I have the following program, which is successfully compiled, but when I'm trying to make a web service in JDeveloper, the following error occurs:
"Validation failed.
The implementation class primePackage.isPrime ofport type MyWebService contains parse errors."
import java.io.*;
import java.util.*;
class isPrime
public static void main (String args[])
Scanner reader = new Scanner(System.in);
int n;
System.out.println ("Enter a number you want to know is it prime or not");
n=reader.nextInt();
if (isPrime(n))
System.out.println ("True");
else
System.out.println ("False");
static boolean isPrime (int n)
int i=2;
while (i<=n-1)
if (n%i==0)
return false;
i++;
return true;
}

Hi,
Can anybody tell me please, is it possible to create
a Web Service from java class where the input from
user is required ?Yes, the parameters of your method will be mapped in WSDL.
But i've some considerations about your code.
I suggest you change the name of isPrime do Prime, its a good code convention to put the name of class starting with Upper case. and isn't good the name of class equals to name of method.
I suggest you to change the "static boolean isPrime (int n)" to "public boolean isPrime(int n)" to publish a method as a WebService method it's must be public and not static. After this change try to generate your Web Service.
Regards.

Any difference in creating a web service from a java class or session bean?

Hi,
The JDeveloper tutorial at http://www.oracle.com/technology/obe/obe1013jdev/10131/devdepandmanagingws/devdepandmanagingws.htm demonstrates creating a web service from a plain java class. I'm wondering:
- Is it possible to create a web service from a stateless session bean instead of a java class? If so, what's the proper way to do this in JDeveloper? When I tried doing so in JDeveloper 10.1.3.0.4 (SU5) using the J2EE Web Service wizard, the wizard did not list the session bean in the Component To Publish dropdown (it does list any java classes available in the project). I can proceed by manually typing in the name of the session bean. After the wizard completes though, the @Stateless annotation that had been in my session bean class code is removed and replaced by a @WebService annotation. The end result is that it looks like it made no difference whether I had tried to create the web service from a session bean or plain java class as the annotations in the resulting web service code are the same (although if I had started from a session bean, the class for the web service still implements the Local/Remote EJB interface that the session bean originally implemented).
- Assuming it's possible to create a web service from a stateless session bean, is there any advantage/disadvantage creating a web service from a java class vs a stateless session bean? I'm creating the web service from scratch so I also need to either build the java class or stateless session bean the web service would be based on from scratch too.
Thanks for any ideas about this.

Hi,
EJB Session beans (EJB 3.0) are deployed as WebServices by annotating the class with @WebService and the methds with @WebMethod (both tags require you to add the JSR-181 library to your project (available in the JDeveloper list of libraries)). Unlike the J2E WebService, the EJB session bean service is turned into a WebService upon deployment. This means you obtain teh WSDL file after deployment
- Assuming it's possible to create a web service from a stateless session bean, is there any advantage/disadvantage creating a web service from a java class vs a stateless session bean?
The difference is that EJB Session bean based web services are integrated with the J2EE container, which means that they can leverage container services like transaction handling, data sources, security, JMS etc.

Guys,
You are asking about an issue that was a pain in the nick for me few months ago. The problem is that you won't find mych help here as I figured out that Apex geeks here either did not do much webservices or ended up hating it as i do :) . This is an error that can be due many different reason, let me ask you this:
1- Does your the other system you are trying to call through webservices using HTTPS ?
2- If yes, did you create a valid oracle wallet for that https connection ?
3- Make sure you are using the correct URL ( am sure you do, just double check )
4- If using a proxy, then you have to define that in the web service reference creation page
provide more info and I hope I can help you with this,
Sam
Please reward good answers by marking them correct or helpful!

Creating a Web Service From an existing Java Project

Hi folks,
I'm new to web services and SAP Netweaver so I need to know if I can use my exisiting Java codes (not EJB's though) for creating web services and the WSDL. I've already gotten the codes working and all and just need to make them into web services and deploy them (plus give my WSDL).
I've noticed in some samples that they used EJB's for creating new web services and I've been trying to find samples/steps on just creating webservices from exisitng java codes. I've been using AXIS but I've been told that creating web services using the Netweaver Developer Studio is rather easy.
Thanks in advance!

Hi Amol!
Thanks for the link
I was trying it out, but could you see if this was correct:
I just made one simple java project (with one class file) and using the link you sent me and did just the step for using the web service Creation Wizard. I made it say Test service and got into the Web Services Explorer but it says it couldn't open my wsdl:
IWAB0379E Unable to open http://localhost:50000/HelloBeanService/HelloBean?wsdl.
IWAB0135E An unexpected error has occurred.
WSDLException
WSDLException: faultCode=OTHER_ERROR: http://localhost:50000/HelloBeanService/HelloBean?wsdl
Did I miss a step?
Thanks again!

Create a web service from java bean and map exceptions to SOAP faults

Hi,
We have to expose our Session stateless EJB3 as web services. I've tried to use annotations and jdev wizard "java bean to web service" and it works fine.
Our problem now is that our methods can throw a business exception that contains a list of error message strings to be presented on the client.
I did not find any way to use annotations to make it build a wsdl with soap fault mapped to our exception class. Neither I could to make the wizard to create wsdl with faults.
As we are exposing already designed and implemented classes as web services, I think the bottom-top (java->wsdl) approach is better that top->botton (wsdl->java). Therefore, I'm looking for a possibility to generate the web services from the java beans and have the exception be mapped to a soap fault message.
We are using jdev 10.1.3.1 and OAS 10.1.3.1., is there a way to map exceptions to soap faults using bottom->top approach?
thank you

My last question concerning web services:
I have already written a session bean and I'd like to add some methods
as a web service to it, how do I do that?
Or I can only create another bean for a webservice and cannot modify the
original one?You might create web service with existing sources and select you bean. New web services with appropriate lookup method will be generated.
All web service method, that will be exposed in web service, you
should add itself (Pop-up menu Web Service -> Add operation)

How can we call a WEB SERVICE from an Oracle DB?

<h2>
What the methods available to call a WEB SERVICE from the DB. I.e. through a DB Stored Procedure?
I was given this article by a colleague, but since it’s a 2005 one, I feel it could be outdated?
http://www.oracle.com/technology/pub/articles/mensah_dws.html
Also, is it possible to write ONE “Common” DB stored procedure to call ANY WEB SERVICE?

<h2> No Girish, what I meant is, since it is 2005 article, the method it describes to call a WS is out of date.
Because I am quite sure in 2009, 4 years later Oracle must have added built-in packages and other methods to simplify it???
Also, I would be very grateful if you advice on the other issue: Is there a way to create a single DB stored procedure to call ANY WS?? i.e. a common routine to call any web service?

Creating a Web Service from EJB 3.0 - J2SE 5.0 Collection mapping problem

Hi,
Apologies if this is the wrong forum, I'm not quite sure where it fits in.
I have some Toplink JPA entity beans that I access through a session bean. I am then trying to create a web service based on the session bean by deploying it to a 10.1.3 application server. This is based on the documentation at http://download.oracle.com/docs/cd/B31017_01/core.1013/b28764/web_services002.htm#CHDJEDDH
The two entity beans are like:
public class Event {
private java.util.List<EventDetail> eventDetailList;
public Event() {
public void setEventDetails(java.util.List<EventDetail> eventDetailList) {
this.eventDetailList = eventDetailList;
public java.util.List<EventDetail> getEventDetails() {
return eventDetailList;
public void addEventDetail(EventDetail eventDetail) {
this.eventDetailList.add(eventDetail);
public class EventDetail {
public EventDetail() {
The session bean has a method like:
List<Event> listParents();
When this is deployed to the application server I expected a complex type like ListOfEventDetail to be generated in the WSDL, as shown in http://download.oracle.com/docs/cd/B32110_01/web.1013/b28975/apptypemapping.htm#sthref966, and the Event complex type would have an element of ListOfEventDetail. Instead the Event complex type looks like this:
<complexType name="Event">
<sequence>
<element name="eventDetails" type="ns1:list" nillable="true"/>
</sequence>
</complexType>
<complexType name="EventDetail">
<sequence/>
</complexType>
and ns1:list appears in a different schema:
<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap11-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="http://www.oracle.com/webservices/internal/literal" targetNamespace="http://www.oracle.com/webservices/internal/literal" elementFormDefault="qualified">
<import namespace="http://wsdl/"/>
<complexType name="list">
<complexContent>
<extension base="tns:collection">
<sequence/>
</extension>
</complexContent>
</complexType>
<complexType name="collection">
<sequence>
<element name="item" type="anyType" minOccurs="0" maxOccurs="unbounded"/>
</sequence>
</complexType>
</schema>
However, if I change the getters and setters for eventDetailList in Event to setDetails and getDetails like this:
public void setDetails(java.util.List<EventDetail> eventDetailList) {
this.eventDetailList = eventDetailList;
public java.util.List<EventDetail> getDetails() {
return eventDetailList;
the WSDL is generated as I expected:
<complexType name="EventDetail">
<sequence/>
</complexType>
<complexType name="Event">
<sequence>
<element name="details" type="tns:ListOfEventDetail" nillable="true"/>
</sequence>
</complexType>
<complexType name="ListOfEventDetail">
<sequence>
<element name="item" type="tns:EventDetail" minOccurs="0" maxOccurs="unbounded"/>
</sequence>
</complexType>
After messing around with various combinations of things, it seems that if the getters and setters have more than just the initial capital letter the (eg getTheThings instead of getThings) the WSDL gets messed up. Does anyone have any ideas what is going on here?

Using <autotype> and <source2wsdd> to generate what I need. Now WL seems happy.

How can I create a Web Service with several classes

Hello,
I developed an API which I want to use to create a webService that offer an acces to all the classes and use all their methods.I tried this with Netbeans but I view that I will have a WSDL file for each class.
But I have tested the yahoo api web service of the image search and it offer acces to several objects such us request and result.So I want to make a service that offer the use of several objects. Can I do this.If yes how ? Because I have read tutorials about WebServices and they mention that to create a webservice I must have an EndPoint class so only one class.
Please I juste began with webservices so I don't know how to do.
Thanks in advance.

I don't believe this is possible when starting from Java. I think you need to start with a WSDL to get this to work. I am curious as to why having multiple WSDLs is an issue, would you care to eloborate.
Thanks
