Expose a Human Task as a web service, is posible ?

Hi everyone, is there a way to expose a human task as a web service using BPM Studio or other way ?

Hi Carlos
Human Task by itself do not have any significance or play any role. Its the Process or Sub Process where that Human Task is used is what is important. And you can Expose any BPM Process as a WebService. Infact by default it is already a WebService if you observer closely. We can generate a WebService client for any BPM Process.
So I am not clear on what exactly you are asking by exposing a Human Task as Web Service which I guess is NOT possible. This Human Task .TASK file do not have anything except for its definition.
Thanks

Display the status of parallel human tasks in ADF web page (BPM 11g)

Hi,
We create a BPMN process (BPM 11g) which splits into parallel branches. Each branch has its own user activity. We want to show the task status of ALL the parallel user activities (running or completed) in the ADF web page implemented for the user activity so the user would have the whole picture of the process.
In another words, we are able to check the status of the component instances associated with the process instance in the Oracle EM. We want to provide the similar information (in our case, we only want to show the status of the human task components) to the user when they access the human task page.
I wonder if the only solution is to write Java code with the API to lookup the BPMN process instance. We try to avoid Java coding if possible. Please advise. Also, so far, I have not found any complete instruction/document on how to access the BPMN process instance and check the tasks etc. through the API. Please help if you know where I could get such information.
Thanks a lot,
Helen

How to expose custom methods of servlet as web services

Can i know how to expose the custom methods of the servlet as web services. if it is not posssible then what alternate ways are possible other than ejbs?
regards

Hi
I want to know that whether the custom methods of servlet can be exposed as webservices or not?
Secondly is there init method like we have in servlets so that we can do all the one time loading in the init() method.

JWSC Ant task with JAXWS web services failed

Stateless EJB (exposed only one fn) as a web service - Error illegal public

I have a stateless EJB which has 3 methods.
I expose one of them only as a web service.
But when I test my web service I receive an error...
500 Internal Server Error
Servlet error: The class blah.blah.I_EmpRemote contains illegal public methods.
These methods do not conform to the
restrictions imposed by the web service implementation
Offending methods:
public abstract blah.blah.Employee blah.blah.I_EmpRemote.GetEmployee(java.lang.String) throws java.rmi.RemoteException
public abstract blah.blah.Operator blah.blah.I_EmpRemote.GetOperator(java.lang.String,int) throws java.rmi.RemoteException
So does this mean .. I should make sure all or none of my methods of an EJB are exposed in the Web Service ?
Or I can resolve this in any other way ?
Thanks,
Krishna

Or is it becoz the two methods that it objected to were returning user-defined objects and not String, void, Integer ... that a web service can recognize !
But still ... why cannot it just ignore the methods that are not exposed ?
Can someone throw some light on this.
Thanks,
Krishna

Follow up to web services question: How do I expose java components as web services on iPlanet 6.0 app server?

My task - my company has several legacy PowerBuilder applications that access a variety of Sybase and MS SQL databases. Rather than re-inventing the wheel by re-writing these applications in Java, we would like to enable these applications to call java components (EJBs) that will provide new functionality. I would need a piece of software called CSXtend (from www.cynergysystems.com) to allow PowerBuilder to call a web service. However, I am not sure how to expose my business functions (EJBs) as web services on the iPlanet 6.0 App server. Thanks for all previous responses! Any additional info would be greatly appreciated!

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.

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 Object Oriented Service code as Web Services?

Hello All,
I would appreciate for your insight on this matter!
Web Services are basically RPC (Procedure Oriented) over Soap. Each service invocation by a client results a procedure execution on the server side (In many case, a service class may need to be instantiated before the procedure can be called).
Suppose I have developed server-side logics in Object Oriented manners. How can I expose the OO server logics as Web Services? Does JDeveloper handle OO services any different from PO (procedure-oriented) services as far as the generated wrapper code/interface and WSDL?
Specifically, I have the following example in mind. Assume we are able to successfully expose an OO services. A client calls one of the OO service (let's say service1 in portType1) the 1st time, and establish some transit state (not committing into DB), the same client subsequently calls another service (service2) of the same server portType1. How would the server retrieve the transit state established earlier by service1 while executing service2? (note, this situation would not be resulted in a procedure-oriented case. since each RPC call is independent from the others)
I realize that "stateful" deployment may be of an option. However, stateful seems relying on client cooperation (e.g., via cookies) to establish context across multiple invocations. This may or may not be possible given an arbitrary client parties write its client code based on a WSDL.
Another option I can think about is for Jdeveloper to generated different code for PO services vs. OO services. However, it seems not the case in current Jdeveloper.
Thank you so much!

Web services in general have two styles of invocation: RPC style and Doc style. RPC maps as you say directly to methods on Java class (or if a DB PL/SQL package to procedures and functions).
The alternative, DOC, generally (though not all the time) maps to a message oriented interface. Often DOC style Web services map to messaging infrastructure such as Java Message Service Queues and Topics.
That said RPC works well with EJB's, the component model for J2EE.
Often what folks will do is build a service layer that is very coarse grained when exposing backend infrastructure as Web services. This abstraction typically hides a more OO underpinning (or quite often hides a very procedural backend too).
The bottom line is the Web services do not force an OO paradigm but nor do they hinder you in any way from adopting an OO paradigm.
In terms of JDeveloper currently it supports RPC and supports DOC only with some tweaking. On the server side, the Oracle9iAS infrastructure supports both DOC and RPC.
Hope this is a start to answering what I think is a hard question to answer!

Proxy exposed as a web service but cannot be reached

Hello,
I've exposed a server proxy as a web service and it looks OK in WSADMIN and WSCONFIG, also a service is created in ICM. But when I test the service, the browser page that opens cannot be reached and if I try to send a message to the service, I get the error HTTP Error: Could not POST file.
What might be the cause?
Thanks,

Web Service exposing Java Collaborations vs designing with eInsight

Hello
I have relatively little experience in designing and implementing web services. We are now looking at implementing some minor services with JCAPS.
I would like to have some input on above subject. what are the pros and cons using either of the strategies. Today we do not use eInsight.
I have understood that you do not have access to the SOAP message when exposing a java collaboration as a web service. I can also understand some of the drawbacks if you develop a ws consumer and you want to manipulate the SOAP message. But if you develop a server service implementation, when do you need access to the SOAP message?
Other issues that might arise:
Security
Distributed transactions
Any references to best practice resources, biased towards JCAPS would be highly appreciated.
TIA

Hi again
We are also interested in in using attachments in the SOAP message. I have googled a bit and from what I have found it seams that it is "not supported out of the box"
Can anyone enlighten me in this area?
A general comment, I find it very hard to get information from the documentation of JCAPS, maybe I have missed something so please direct me to the right source if you find my ?? to much "newbie like". Things like, specification of packages, classes, methods, parameters with data types, Exceptions etc where can I find it in JCAPS?
As an example, The SAAJ package throws an exception in the log in 5.1.3, so it must be there. Where can I find information about that implementation in JCASP?
TIA and Br,

Exposing Business Object as Web Service

Hi,
I've designed a Business Object and would like to expose its findAll Operation as a web service. The wizard tells that the operation has Improper operation message cardinality". While browsing through saphelp I found this: http://help.sap.com/saphelp_nwce10/helpdata/en/44/24128b347c1c9fe10000000a11466f/content.htm
Thats nice to know but doesn't solve my problem. How do I create a web service that returns ALL objects?
Thanks in advance for your help.
Bastian
edit:
this on solved it:
CE/CAF: Expose service as Webservice

Hi,
you need to create wrapper method of findAll,
The reason you are not able to expose it as service because findAll resturning array of values instead of one response (or candinality of return is 0..n). So create one wrapper complex type add your BO as datatype of that complex type with multiple cardinality,
In new method add this complex type as response (with cardinality 0..1) and within code call standard findAll and mapp return value to complext type.
It will work.

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,

Expose Existing EJB as Web Service

Hello,
I've recently installed studio enterprise. I've written and deployed the requisite "Hello, World!" stateless ejb. Now, I would like to expose that existing bean as a web service. I know that it simply requires a new interface and some new xml. When I try to expose it with the studio 8 ide, it seems to want to generate a new class file for the web service. Is there a clear tutorial on how to expose an existing bean as a web service without generating unnecessary classes?
All suggestions much appreciated!

Thanks for the quick reply! I took a look, and they are similar to what I am familiar with. I think what I am looking for is specific to the Java Studio IDE. I know that all I need to do is add an interface. The IDE should ( optimally ) genereate all the additional xml, wsdl, etc. This is all easy to do in WebSphere through RAD. I am looking for the equivalent in the Studio Enterprise IDE. The only tutorials I have found have been muddled at best.
I don't want the IDE to generate a new bean class. I just need a new interface to expose the bean as a Web Service. The IDE should be able to incorporate the interface into the existing jar and provide the wsdl.

Expose Stored Proc as a Web Service

Hi,
I'm fairly new to this environment, but I'd like to expose a stored procedure as a Web Service... my client is going to be either a browser/.NET client and we are trying to be independent from ODP.NET. We are testing the performance of Web Services. (our app just stores config info in the db, and we'd like to hit it, get the config and then carry out our function.)
What has to be enabled on my DB for this to occur? Any samples? Is there a FAQ somewhere that describes how to do this?
Thanks,

Hello,
No you do not, the feature is an Application Server feature, and it was supported in OracleAS/Jdeveloper 904 too.
I do not about VS supporting such feature, I doubt it, but what you can do if you are not interested by created a Java (Oracle) Web Service, is to manually code the DB access using C# and expose this class as WS using .Net framework.
What Oracle is doing when publishing DB as WS is facilitating the generation of Web Services and support of complex Oracle Types.
However, I would keep in mind that WS are implementation agnostic so even if you mail platform is .Net it makes sense, to me, to publish some of your DB Object using Java (Oracle) WS then you can consume with any application ...

Serialization error in SAP Web Service.

Hi all,
I have exposed a custom RFC as a Web Service. This is a simple web service that returns Customer Data (from kna1) based on the Customer ID which we provide as input.
In the RFC, I have declared an internal table (G_RET) in the tables section of the RFC.
Now, while testing the web service, I can see a check box with NULL option beside the G_RET. If i check the NULL option for G_RET, I get an error.
XML Serialization Error. Array Property [Item] in class [none] must not have NULL elements. This is restricted by schema description.
This is a high priority task. Please reply to me with any solution that you may have.
Regards,

Your problem has nothing to do with SAP web service. When you expose a RFC function as a web service, you are defining a service contract using WSDL technologies and XML message format enforced by the schema definition associated with the data source.
When a system consume a web service it is upto that system to provide a client framework so that it can provide an implementation enforces by the WSDL contract. Contract terms in WSDL is only applicable to data types, message types, access style and ecoding.
It is upto the client framework to provide a mechanism to send and receive the data as per the contract.
In your case, you are using a Microsoft client, so MS implementation of web service technology play a big role here.
C# XML serialization class from the MS client program you are using to call the program, read the WSDL contract and try to understand the definition and terms and conditions of the messages, types, binding.
In your WSDL you may have constraints applied at each field level of the schemas associated with the input and output messages of the web service methods.
Unfortunatly the way C# XML serialization class understand the terms and condition is confusing and it create a rum time error.
Having said this all stories now let us get into practical way.
1. Test ur web service using a non MS client
2. Make sure it is working, this isolate your issues to the way client understanding the WSDL contracts.
3. Then work with some MS guys in your shop to address this issue.
From your post I hope you are a candidate having experience in working with SAP customization project. However when ever you deal with open technologies such as JAVA, Web Services, it is highly recomended to think outside the BUNN.
AS SAP move towards more open technologies such as JAVA, WSDL, SOAP, WS, XML, XSD it is very important to elaborate your knowledge beyond the scope of a customization project.

Publish XDB web service on apex application

Could any one please help me out to use native oracle XML DB web service on apex application.
In apex application, basically i need to have a report that displays all PO requests with links to each request # to drill down to the form page where the vendor are allowed to submit some corresponding data to th PO request.
All i need is to know how do i use the native oracle XML DB web service to show the report to the vendors with drill down links and capture the data, the vendor submits through the form.
Thanks in advance!!

I think you might be on the wrong track. Web services don't "show" anything really. They take in either XML in the case of SOAP-style web services or an HTTP request in the case of restful web services. They typically return XML, but can return JSON or other machine readable formats. Web services don't have forms and reports. More information here: http://en.wikipedia.org/wiki/Web_service . To have a human interact with a web service, you typically have a UI layer. For instance, in APEX you can build a form or a report on a web service (the same is true for most popular web technologies).
In APEX 4.0+ you can expose a report as a restful web service, but I really don't think that is what you want to do. There's no way that I can think of to use the XDB web services to expose any component of APEX.
In short, people interact with web applications, such as APEX apps. Machines, such as databases or application servers, interact with web services.
So, do you need to expose some component of your application as an API (web service) that vendors can call programmatically from some other technology such as Java or PHP? Or do you want to build a web application that people can interact with?
