ABAP Class as web service

Hi All,
Is there any way to expose a ABAP class as a web service. I know we can create a FM or BAPI and expose them as web service.
Ex : If I have a SalesOrder class and this class has methods like getOrder(),getDetails(),getItems() etc etc
Now I would like to create a service where the above methods are methods inside the service.
(We don't have XI in our landscape)
Please correct me if my assumption is wrong.
Thanks ,Anilkumar

i think you need to embedd the class/methods in a rfc enabled fm to create a webservice.

Add java classes as Additional Classes to web service and JAXB 2.0 usage

Hi,
I start using JDeveloper 11g TP3 to create web service. I encounter two problems.
1. I created a schema file as the following,
<schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://FromWSDL/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://FromWSDL/">
<xsd:complexType name="sayHello">
<xsd:sequence>
<xsd:element name="arg0" type="xsd:string" default="Tommy"/>
<xsd:element name="arg1" type="tns:arg1Enum"/>
</xsd:sequence>
</xsd:complexType>
<xsd:simpleType name="arg1Enum">
 <xsd:restriction base="xsd:string">
 <xsd:enumeration value="preserve"/>
 <xsd:enumeration value="replace"/>
 <xsd:enumeration value="collapse"/>
 </xsd:restriction>
</xsd:simpleType>
<xsd:element name="sayHello" type="tns:sayHello"/>
<xsd:complexType name="sayHelloResponse">
<xsd:sequence>
<xsd:element name="return" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
<xsd:element name="sayHelloResponse" type="tns:sayHelloResponse"/>
</schema>
then I used TopLink/JPA-->JAXB 2.0 Content Model from Schema, I got four java files: Arg1Enum.java, ObjectFactory.java, SayHello.java, and SayHelloResponse.java.
After, I create a java class with @WebService and @WebMethod annotation. Right Click on the web service class,
select Web Service Properties-->Additional Classes, I added the four java classes. but there are error message for SayHello and Arg1Enum
"the type SayHello cannot be serialized into XML and no custom serilizer has been defined for it"
2. In JDeveloper, I create Java model from the above schema, then reverse the steps, create a new schema from Java Model, the original schema and the schema from Java Model are not same, especially for "defaultValue" and "required" fields for the custom element(SayHello and Arg1Enum).
Any help will be appreciated

First what you mean by "deploying classes as web services"? Chances are you
can do it with something like Glue from The Mind Electric ... but chances
are that you don't want to. What are you trying to accomplish?

Hi, can WebLogic deploy simple Java classes (not EJB's or JB's, just

The WebLogic installation has one measly web services example, and it's an

Exposing java class as web service

Best Practice for WSDL Generate Proxy Class for Web Service with Two Versions

Dear All
Thank you in advance for you help.
I would like to generate proxy classes for same function but with two versions.
Old version web service (v23.2) is used for stable modules in a project which is not going to modify.
However, enhancement is added in new version web service (v24) and is going to use in any future modules.
For example,
wsdl.exe -o="TestProxy.cs" -l:CS -n:Test -sharetypes https://community.workday.com/custom/developer/API/Notification/v23.2/Notification.wsdl https://community.workday.com/custom/developer/API/Notification/v24.0/Notification.wsdl
It generates similar classes with an '1' added at the end of the class name.
ublic partial class Event_TargetObjectType {
private Event_TargetObjectIDType[] idField;
public partial class Event_TargetObjectType1 {
private Event_TargetObjectIDType1[] idField; ...}
Since the function inside some class is the same, is it possible for WSDL.exe to generate proxy classes automatically that if the class is the same, then generate one class only (sameFunction()) but if it detects the class is different, then add '1'
to the end of class name (differentFunction() and differentFunction1())
i.e.
public class sameFunction()
public class differentFunction()
private int a;}
public class differentFunction1()
{ private int b;
Best Regards
mintssoul

Hi mintssoul,
As per this case, I have shared corresponding details below :
1.As far as I know, WCF doesn’t support method overloading directly
2.Because WSDL doesn’t support method overloading (not OOPs).
3.WCF generates WSDL which specifies the location of the service and the operation or methods the service exposes.
4.WCF use Document/Literal WSDL Style : Microsoft proposed this standard where the soap body element will contain the web method name.
5.By default all the WCF services conform to the document literal standard where the soap body should include the method name.
6.but you can differ the method in the same manually by using Name attribute like below
For example:
    [OperationContract(Name="Integers")]
    int Display(int a,int b)
    [OperationContract(Name="Doubles")]
double Display(double a,double b)
7. Or I suggest you that can use svcutil to map multiple namespaces for generating wcf service proxies .
    for more information about this, refer here :
http://stackoverflow.com/questions/1103686/use-svcutil-to-map-multiple-namespaces-for-generating-wcf-service-proxies

WSDL error during generation of ABAP proxy for web service

Hi friends,
I am getting error during the generation of ABAP proxy object for web service developed in .NET .
Error : Proxy generation terminated: WSDL error (<extension> not supported).
How to make this WSDL file compatible for ABAP proxy.
I have tried to edit WSDL file in XML Spy but did not get any option to replace/remove the tag <extention>.
If any one worked on this. Please help me its urgent.
Thanks and regards,

Does ABAP Proxy Generation support <extension> ?
Is there a list available of what is supported and what not (please consider I do not have access to sap notes)?

Start ABAP Debug in Web Services Application - won't take non-Dialog user

Hello all. We are trying to Replicate Employees from SuccessFactors to SAP ECP/ERP with a delivered integration from SAP, but we''re having trouble interpreting some of the errors we're getting in the Application Log
As shown in the Web Services Utilities Message Monitor - our message is successfully Delivered - we would like to set a break-point in Class CL_PAOCF_EC_EE_MDR_IMPL and run our test. Unfortunately we have to use a Technical User in our middleware connector to consume the Service (to connect to the Java Application Server?) and setting External Breakpoints or enabling Debugging in SICF will only permit Dialog users. Does anyone know how we can run our Web Service and invoke an External Breakpoint in our application posting Class?

Hello Keith,
What is the "user type" for this user? In our system we have the user for the middleware defined as "Service type" and external debugging is possible with that user.

Suhas

Abap Class for Enterprise Service

Hi guys.
I've published as webservice in SAP ECC as enterprise service get it in Enterprise Service Workplace.
I have two questions:
1- How can I know the abap class associated to this enterprise service.
2- Could I extend the functionality of this enterprise service? For instance I'd like to response with one more field. Is that possible or I have to create a new one?
Thaks a lot.

Examples about ABAP Proxies and Web Services creation

Hi everybody.
I have been reading SAP NW PI 7.1 help about Web Service creation and sincerely, I am a bit confused. Also I have searched SDN forums, blogs and documents but my confusion persist.
I will try to depict my integration scenario below.
SLD are conformed by two machines: SAP ECC 6.0 system, client 100 and SAP PI 7.1 system, client 001.
There are two integration scenarios.
1. ABAP Client Proxy -> PI -> Web Service
I need to consume a Web Service provided by a third part. They provided me with WSDL files and I imported them into ESR. I already construted all other objects (data types, message types, etc.). In the examples I found I cann't see what to do with those definitions, I don't find any suitable example. This is an asynchronous scenario. The Web Service will be consumed from SAP ECC 6.0 system through an ABAP Cliente Proxy.
2. Web Service -> PI -> ABAP Server Proxy
I need to provide a Web Service for others to consume it. I already have created the WSDL for Service Interface I created in ESR using the respective wizard in Integration Builder. This is an asynchronous scenario. The Web Service will be consumed by others outside landscape configuration. When the Web Service is consumed must run an ABAP Server Proxy.
In spite of my investigation about Web Services building in SAP NW PI 7.1 I cann't finish my work successfully.
I just need a good example, any suitable example for each integration scenario.
Thanks in advance.
Rafael Rojas.

Hi,
1. ABAP Client Proxy -> PI -> Web Service
1. Create all necessary objects in ESR
2. Create integration scenario objects with PROXY as sender SOAP or WS adapter as receiver
3. Create client proxy in your SAP backend using SPROXY
4. Create ABAP client proxy to execute the proxy which then will call your PI runtime to execute the webservice.
2. Web Service -> PI -> ABAP Server Proxy
1. Create your necessary objects in ESR
2. Generate server proxy in your back end system
3. Create integration scenario objects with PROXY as receiver and SOAP or WS adapter as sender
4. Generate WSDL from integration scenario and pass it to your partner.
You can find many blogs which discuss these steps in more detail.

User defined class for Web Services

I am trying to use the Web Service Publishing Wizard to publish
a class as a web service. The wizard will not allow me to select
the method I wish to publish. When I click on the "Why Not?"
button the message says:
"One or more parameters did not have an XML Schema mapping
and/or serializer specified"
I use user defined classes as parameters of the methods of the service web.
How cam i install this web service on "Oracle J2EE Web services"?

If you use Java Beans (or single dimension arrays of Java Beans) that implement the java.io.serializable interface as per this article:
http://otn.oracle.com/tech/webservices/htdocs/samples/customtype/content.html
then Oracle9iAS will handle the publishing process of custom data types. The publishing wizard in Oracle9i JDeveloper 9.0.2 doesn't support this yet, but the link in the article to the JDeveloper help gives a fairly straightforward workaround. This workaround will be eliminated in Oracle9i JDeveloper 9.0.3 (due late August).
Does representing your parameters as Java Beans work for your problem?

Contivo Java class as web service

Hai,
We used the contivo mapping and from that generated one java class. We need to use it as webserivce.
With the help of Eclipse and AXIS( 1.4 ) made a try, and while making it as webservice , getting warning as The service class "Transform_source1_to_dest1" does not comply to one or more requirements of the JAX-RPC 1.1 specification, and may not deploy or function correctly.
In wsdl file also some errors are getting in namespace imports.
So please help me to solve this problem.
Can we use the Contivo generated java class directly as a web service ? for that which web service engine can be used?
Apache AXIS 1.4
JDK 1.5
Contivo Analyst 3.11.2.1.5
Thanks in advance.
Rgds,
Rajeev

Rajeev,
Contivo transforms can be invoked indirectly through two APIs, which have often been used for invoking transforms from web services. One API is called Transform and the other is called TransformAny. The Javadoc for both is distributed with Analyst, and the "Runtime Guide" is also distributed with Analyst.
Does this get you closer?

Error converting CFML arguments to Java classes for web service invocation.

Hello all.
I am working on writting a small application that will use a web service that is provided by our IVR (Angel.com). I am able to login, however when I attempt to do anything with complex objects, I get the error stated in the title.
It seems to be having a problem with the array, because when I remove it, or turn it into a simple string, i get errors about the function not being found. I am fairly new to web services, and especially dealing with complex data types, so any help would be much appreciated.
You can see my testing page at
http://webservices.fpitesters.com/AngelCalls.cfm
The WSDL I am using can be found at
http://www.angel.com/outbound/wsdl/OutboundCallService.wsdl
Here is sample code that does what I want it to do in Java / Apache Axis
http://www.socialtext.net/ivrwiki/index.cgi?java_sample_code
Here is a description of the function I am having problems with
http://www.socialtext.net/ivrwiki/index.cgi?placecall
And attached is my code.
 <cfset email = "xxxxxxxxxxxxxxxxxx">
 <cfset pin = "xxxxxxxxxxxx">
 <cfinvoke webservice="http://www.angel.com/outbound/wsdl/OutboundCallService.wsdl" method="login" returnvariable="login">
 <cfinvokeargument name="email" value="#email#"/>
 <cfinvokeargument name="pin" value="#pin#"/>
 </cfinvoke>
 <cfdump var="#login#">
 <cfset Token = login.getToken()>
 <cfdump var="#token#">
 <cfset CallItem.maxWaitTime = 100>
 <cfset CallItem.phoneNumbers[1] = "7632344306">
 <cfset CallItem.siteNumber = 100041>
 <cfinvoke webservice="http://www.angel.com/outbound/wsdl/OutboundCallService.wsdl" method="placeCall" returnvariable="call">
 <cfinvokeargument name="Token" value="#Token#"/>
 <cfinvokeargument name="CallItem" value="#CallItem#"/>
 </cfinvoke>
 <cfdump var="#call#">

If you are not initializing phoneNumbers as an array before setting
<cfset CallItem.phoneNumbers[1] = "7632344306">
it will be passed as a struct with a key of 1. This could cause your argument conversion error.
So:
<cfset CallItem.maxWaitTime = 100>
<cfset CallItem.phoneNumbers[1] = "7632344306">
<cfset CallItem.siteNumber = 100041>
Will result in
struct
MAXWAITTIME
100
PHONENUMBERS
struct
1
7632344306
SITENUMBER
100041
<cfset CallItem = StructNew() > 
<cfset CallItem.maxWaitTime = 100 >
<cfset CallItem.phoneNumbers = arrayNew(1) /> 
<cfset CallItem.phoneNumbers[1] = "7632344306">
<cfset CallItem.siteNumber = 100041>
Will result in
struct
MAXWAITTIME
100
PHONENUMBERS
array
1
7632344306
SITENUMBER
100041

Consuming a Web service thru XI with Web Dynpro for ABAP

Hi all,
Does anyone know how to call a web service thru XI from Web Dynpro ABAP. The web service will call an RFC and bring back some data.
Some guidelines on how to achieve this will be very much appreciated.
Thanks
KG.

Hi Kunal,
Do you want to use XI at the runtime of the service ? Usually for a synchronous call, XI is used only at the design time to design the message interface. Using this message interface the proxy class in ur ABAP system can be generated. In the interface method of your proxy class you can call your RFC. Finally generate a webservice out of this proxy class via SPROXY tsn.
Get the WSDL url of this webservice in tsn WSADMIN . Using this url you can call the service (peer-to-peer, no XI involved at runtime) with Webdynpro.
I hope this answers your question.
Regards,Girish
