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
Mithun

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.

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 Applications Studio for ByDesign Partners

If a ByDesign Partner requires access to SAP Cloud Applications Studio for some development work for ByDesign can they request for the Studio for Free or do they have to pay for the use of it?

Any update by SAP on this? I'm unable to get to any help documentation via the SDK and links to API's and Web Services are all broken. The web site is not of much use right now to research any API capabilities, etc. ...

Extension fields in forms using Adobe LiveCycle Designer and SAP Cloud Application Studio.

Hello everyone,
I am new to using SAP Cloud Application Studio and am currently working on forms.
I have created some extension fields in the dunning letter form message type : FormDunning Notification.
Upon activating, the extension fields do show up in backend form data type structure.
However i am unable to find the fields in the front end form under Form Template Maintenance.
I have tried opening form with open editor as well as downloading template and opening in Adobe LiveCycle Designer .
After creating the data connection in adobe ,the first field (ProjNumDun ) do appear in correct place in data view.But i cant find the rest of the fields.
Any help,guidance and suggestion will be really appriciated.
Thanking in advance,
Kamakshi

Kamakshi,
First, any extension fields added must be explicitly assigned to appear on the forms. Through Front-end Adaptation, this would be via the "Further Usage" link. Within the SDK, you'd right-click the XBO and select "Enhance Forms" (which would take you to the same screen as you'd end up at in through front-end").
You must select "Add Field and Edit..." to actually assign it to the Form Template schema.
Once this step is done, re-download the Form Template, and make sure to reload the Data Connection within LiveCycle. Through there, you should see your fields. You'll likely have to dig for them - they appear at the very end of the child elements.
Note that, while fields added through the front-end have a long string appended to the end (for example, it would appear as "ExtensionField_1234AISU897234HJA" if added via front-end adaptation), the fields added via the SDK do NOT have the suffix (you'll be looking for an element with JUST the field name, i.e. "ExtensionField")

SAP Cloud Application Studio 1502 UI Designer proxy error

Hi,
When starting the UI Designer in SAP Cloud Application Studio 1502 I got the following error:

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.

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!

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

A couple of links that may be of help:
http://www.netbeans.org/servlets/ReadMsg?listName=nbj2ee&msgNo=1218
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 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.
Thanks

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!

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.

SAP Cloud Application Studio 'Save' on Tickets

Hello Experts,
I had attached an embedded component 'Batch Info' on the 'Ticket' Screen. For one of the section group, I want these fields (Claim Justified [dropdown], Status [dropdown], Comments [text]) should get Saved on 'Save' button of the Ticket.
I had created an association to the Service Request in my custom BO, added these fields in the extension object and in the script (BeforeSave) i want to save the values provided in these fields. Is this the right approach to achieve the desired result?
Any sort of information is welcome.
Thanks and Regards
Pragati

Hi Pragati,
I dont know exactly what you want to do, however you can use embedded component in Ticket screen to show data from custom BO. You approach is OK.
You can get lot of help from this portal, just goto content and search.
