Expose a class method as web service

hi ABAPers,
is it possibile to expose a class method as web service? I would like to write a base class with common code, while derived classes implement specific application logic.
I have both R/3 6.40 and Netweaver 7.0 kernels, so I'm interested in both.
thank you.

No, it is not yet possible.
You can only create a web service for an RFC Function Module, Function Group or Business Object.
You may create a RFC FM as a wrapper to your Class methods and create a web service on the RFC FM.

Exception while exposing Application Module Methods as Web Service

Hello Everyone,
I am working on Jdeveloper 11.1.1.3.0 version and tried to expose one method of application module as web service. To do this, i used "Service Interface" tab of Application module within Jdeveloper and Jdeveloper had generated all interfaces, stubs, code for the Session bean required for web service. I am now trying to "Test Web Service" from the implementation class generated then i am getting this error in Weblogic deployment. Any help/pointers would be highly appreciated.
I used another installation of Jdeveloper same version at my collegues desktop but getting the same error. Not sure, if this version of Jdeveloper is having issue in exposing application module as web service. I think that database related exception can be ignored as no database call is being made by the application.

How to call ABAP function module/ class method through web service?

Hi Colleagues,
I need to write an iphone version of current ABAP program. I want to call ABAP method and function module through my iphone so that I can re-use the ABAP APIs.So I choose web service. Can you give me any details information about how to do that?
Thank you very much

Hi,
you need to create webservice out of FM. goto SE80 and follow the webservice creation wizard. Finally use webservice url for calling FM (remote enabled) from your iPhone.

Expose AM methods as web services

Hi All,
As searched results from the forum, most of posts talking about how to consume WS by generating java file from wsdl. My question is, can we expose an AM method as web services? If answer is yes, may I have some high level steps for following up?
If we expose AM method as an web service, does that mean we have to pack all FND/OA classes in war file then deploy it into OC4J container?
We are using an old AS and even don't have standalone OC4J server installed. Even I can install a standalone OC4J but I still don't know how to resolve above question.
Thanks & Regards,
KJ

I have used Glue (http://www.themindelectric.com/products/glue/glue.html) to expose some of our stuff as Web Services. I recently found this on serverside. It's pretty good.
http://www.theserverside.com/resources/article.jsp?l=Systinet-web-services-part-1
I believe that the middleware they use can be plugged into IPlanet. There is also an article in the knowledge base on the IPlanet site.

Expose C based system as Web Service

hi,
I have a C based MES which is storing data in non-relational file based DB from Stratus.
I need to integrate this system with SOA.
Not sure how do I expose this system as a web service.
Any thoughts, any links are most welcomed.
Thanks in advance.

No, it is not yet possible.
You can only create a web service for an RFC Function Module, Function Group or Business Object.
You may create a RFC FM as a wrapper to your Class methods and create a web service on the RFC FM.

Exposing Java method as Web service

Hello,
I would like to know how can I make a Java Method expose as a webservice using BPEL.
I have created a java class To do some processing. I want to make this as a service. Is there any sample code to do this? Please provide any links..

If you used the Web Service Wizard the easiest thing to do is:
1. Delete the WS class - when prompted also delete all artifacts - you should now see your original class files. *
2. Add extra methods.
3. Regenerate web service using same parameters as previously (make sure you use the same namespaces).
(4. Apply any customisations you made)
*Occasionally this will not work and will not remove the references to the WS artifacts from the project file, in this case you will need to manually remove them from the project xml file.
You can also edit the project to make the classes visible (can't remember the exact steps for this, it's been a while), change the classes and regenerate services, however this will overwrite any customisations you have made, so is little different to removing the artifacts and regenerating.
Finally you can make the classes visible as above, updatethem and then manually edit the other web service artefacts (<name>-java-wsdl-mapping.xml,webservices.xml, oracle-webservices .xml, Interface, etc). This is a lot more tedious than using autogeneration.

Unable to expose a method in web service

Hi,
My scenario is to expose a method in service. This method will take date as input & should return all the rows.
To Implement this, I took employeeVO of HR DB(Employees Table) & created a ViewCriteria "GetEmpbyHireDate" with Hiredate as input param.
& in AMImpl the code is
public BaseEmployeeVOImpl getEmployeesByHireDate(Date hiredate){
BaseEmployeeVOImpl baseEmployeeVO = (BaseEmployeeVOImpl) findViewObject("BaseEmployee1");
baseEmployeeVO.setApplyViewCriteriaName("GetEmpbyHireDate");
baseEmployeeVO.setNamedWhereClauseParam("pHireDate", hiredate);
baseEmployeeVO.executeQuery();
return baseEmployeeVO;
The issue is I'm not able to see this method in "Available" list of Web Service Wizard.
Help me in understanding what is missing ?
Thanks in advance.
P.S. from Jdev Help I understood that "Only methods with simple attributes as parameters and return types that are either void or view rows will appear in the list." & my method is returning rows of a EmployeeVO.

Hi,
2 comments:
1) View Criteria can be directly exposed as find methods. Its on the last wizard page (just click the View Criteria tab). So no need for an Impl method
2) If you wanted to expose a method, then the documentation I think is crystal clear: "oracle.jbo.server.ViewRowImpl or any subtype" Your method returns BaseEmployeeVOImpl (see the difference ?)

Expose ADF Business Components as Web Service

Hi,
In order to expose ADF BC as Web Services, and return a set a rows from a table, I have followed the tutorial on this page :
http://www.oracle.com/technology/tech/webservices/htdocs/series/pattern/
However, the set of rows returned are un-typed XML elements, because the method is :
public Element getEmp(int empNo)
getEmpView1().setWhereClause("empno = ?");
getEmpView1().setWhereClauseParam(0, new Number(empNo));
return (Element)getEmpView1().writeXML(1,Row.XML_OPT_ALL_ROWS);
As a consequence, in the WSDL the response port is returning a complex type with an "<any />" element. Instead, I would like the response complex type to be an Employee type.
How can I get the AppModule method to be something like :
public Employee getEmp(int empNo)
< what is here ? >
Can I generate the Employee class automatically with ADF BC and serialize it to expose the method as a Web Service ?
Thanks.

How to expose sort attributes in a web service created on a AM 11g TP4

I'm using Jdeveloper 11g TP4 to create a web service on the application module.
When I run the web service, it is working fine. Can someone tell me how to expose the sort attributes for the user to choose?
How do I expose the sort Order for the user to select?
These are the steps I followed:
1) Created a new application.
2) Created a view object in the Model project.
Created one bind variable.
Created new view Criteria and used the bind variable.
3) Created a new jspx page.
From the Data control dragged and dropped the Named Criteria on to the page and used "ADF Query Panel with Table..."
4) Ran the Jspx page. It works fine.
Double Click Application Module.
Click on tab Service Interface.
Hit New, this will open the Wizard to Create a new Service Interface.
Followed instructions and selected all the applicable methods to expose as web service.
At the end of the process, wsdl, xsd, java files are created.
I'm able to run this web service.
The field to query the data is exposed in the Web Service.
Is there a way to expose the sorting attributes to be selected by the user? i.e. I want to expose the fields to the user.
Thanks,
Jagadish.

Why bother with TP 4? JDev 11g is already production.

How to overload method in web services ?

hi all !
how can i overload a web services method ? , i hear about using javax.xml.ws.RequestWrapper , but when i try to use wsimport , it say : error dupplicate method.
this is the sample from forum :
package my.ws;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;
@WebService
//(name="HelloWS", serviceName="HelloWSService")
public class Hello {
      * Web service operation
     @WebMethod
     @RequestWrapper(className = "com.veera.Clac.CalculatorRequest", targetNamespace = "http://Calc.veera.com/")
     @ResponseWrapper(className = "com.veera.Clac.CalculatorResponse", targetNamespace = "http://Calc.veera.com/")
     public int add(@WebParam(name = "a")
     int a, @WebParam(name = "b")
     int b) {
          // TODO implement operation
          return 0;
      * Web service operation
     @WebMethod
     @RequestWrapper(className = "com.veera.Clac.CalculatorOverloadRequest", targetNamespace = "http://CalcOverLoad.veera.com/")
     @ResponseWrapper(className = "com.veera.Clac.CalculatorOverloadResponse", targetNamespace = "http://CalcOverLoad.veera.com/")
     public String add(@WebParam(name = "v")
     String v) {
          // TODO implement operation
          return "Veera";

Hi, Eric,
Thank you for your quick reply.
The web service I am trying to develop is basically a generic Data Access Component to bridge between SQL server and a desktop .Net application. The application will have about 3000 users from WAN, therefore we want to have a server side component to handle connection pooling etc. Because of limitation of current servers, we are asked to develop a Java Web Service, instead of MS WS.
To make the component more reusable, I am thinking to have methods like this in the service:
RunQueryReturnRS(String Sql, WebRowSet, rs)
RunQueryReturnInt(String Sql, int NumRecdImpacted)
RunStoredProcedureReturnRS(â¦.)
RunStoredProcedureReturnInt(â¦.)
â¦â¦
You see, I would like to get whole resultset back to client, including both metadata and data in a format of generic resultset. When I paged through the Sunâs document, finding WebRowSet is claimed to be seariable, and ready for Web Service. I thought if I can use WebRowSet that will save me time to write new classes to hold resultset info and pass back to client.
Could you please tell me if it is a feasible approach?
Thank you.

Overloaded ejb methods as web service

I implemented an ejb as a web service. The ejb has 4 overloaded methods. When I looked at the generated wsdl, only one signature was exposed as a web service. Is there a way to make all 4 overloaded methods available to the web service ?

Hi Sandy,
The WLS 6.1 docs clear states that method overloading is not supported with WebLogic
Web Services:
http://e-docs.bea.com/wls/docs61/webServices/develop.html#1034539
However, you might be able to simulate something similar by passing a org.w3c.dom.DocumentFragment
to the method. For example,
public org.w3c.dom.DocumentFragment overloadedMethod(org.w3c.dom.DocumentFragment
variableArgs)
This allows you to use the flexibility of XML to provide various input and output
parameters for the method. In the method's implementation, you determine which
arguments have been passed by parsing the variableArgs node. For quasi type safety,
you could use the xsi:type attribute to associate data types with fragment elements.
Note that you will need to use literal XML encoding to do this.
