Web Services Flow - Flow Diagram

Hi,
Can anyone let me know what is flow from a Client to Web Services to Server and back. (ie. I need a flow diagram when a client tries to access the Web Services, how does it respond)
Xpecting an early reply
Rgds,

sounds like a homework assignment.
Google is your friend. Aside from that...

Calling Siebel web service from BPEL flow

Hi,
I am using Jdeveloper 10.1.3 to build BPEL.
Does anyone have a sample to call Siebel web service from BPEL flow?
I cannot make web service call success by adding partner link from BPEL flow.
Error:
Error Code: 10944642 Error Message: Error: Inbound SOAP Message - Session Token is missing or invalid or has expired
My understanding is Siebel needs special soap header.
I can build webservice proxy to call siebel web service, it works fine by overwrite the soap header function. However, I cannot make it work from BPEL flow.
Does anyone have this experience?
Thanks

Anyone has insight on this? Is it possible to call a WCF service with NTLM authentication from SOA.
Thanks!

Using web services in Approval Work flow in OIM 11g

Hi All,
I am a new bie to OIM 11g. I have created an approval work flow and it is working fine.
Now my requirement is to use a web service in the approval work flow instead of directly embeding the java code in Java Embeding Activity. Can some body share me a document or url for the process of doing it.
Thanks in advance for the help.
Thanks,
Preeti

If you are using OIM 11gR2 please refer the below document. All steps are very clear with the screenshots.
http://docs.oracle.com/cd/E27559_01/dev.1112/e27150/request.htm#autoId27
See section 21.3.5.7 Configuring the Human Task and BPEL Mappings
Also see this OBE tutorial for getting idea on Java embedding activity and assigning and retrieving data from global variables in SOA

Creating a Web Service to handle flow between BPEL process and XML Gateway

I am new to Web Services. I have never created one, yet I have the task of designing the following for a project.
Any help as to what steps I need to take would be very very helpful. There is a lot of information on XML, SOA and WSDL out there that it can get very confusing, and sometimes you just need someone to point the way
What I need to do is create a Custom Send and a Custom Receive Program (both web services) handle the message flow between an Enterprise BPEL processes and a Deployed XML Gateway.
BPEL compresses this XML business object document (for faster transmission), and sends remotely to this Custom Receive web service, which in turn calls a decompress java program and then send the document to the XML gateway inbound web service.
The Custom Send web service does just the opposite. It needs to take the business object document from XML gateway, call the compress java program and then send to the Enterprise BPEL.
In a nutshell...these Custom Send/Receive Web services handle the message flow between the Enterprise BPEL process and the Deployed XML Gateway.
What I need help on...
-Creating this in JDeveloper- where do I get started?
-How does a web service receive a compressed file sent to me via BPEL? Does it just sit there waiting for it?
-Is this a synchronous or asynchronous design?
-Will this be 2 web services (Send and Receive) or do I make 1 with 2 functionalities
-How do I call the java compress/decompress program within the web service? (this java function is already created and ready to be called)
-Is this decompressed business object file an XML schema and an XML message? Or just a message?
-I need to send this to the XML Gateway Web Service to load. How does that work?
-I have a Generic XML Gateway WSDL file...I assume I need to take all the info I get and map it to this template? Is this true? How do I do that?
Like I said, any help would be appreciated. Links answers to my many questions would be fabulous.

If you are talking about simple XML transformation of the SOAP payload between the client calling your service and the final destination of the message you are routing, the ESB approach may be a better fit.
If you have more complex transformation in mind, with major processing and rework of the message in the intermediary, you may be better of with using the POJO approach. Write your service and embed a callout to the other service in your implementation. If the two services share the same Java Model, you may even be able to re-use the same Java Bean.
To get SOAP Element instead of Java bean, you just need to use the noDataBinding option with either genProxy and topDownAssemble (or assemble). See the WS-Guide [1] for details. Chapter 18 will give you all the details about the different WSA command line parameters.
Hope this helps,
-Eric

Web service data control based on SOA flow

Hello,
I have an ADF application developed with JDev 11.1.1.2.0. This application uses some web service data controls based on a SOA flow that receives a complex data type as an input parameter and also returns a collection of complex data type.
I have a page that has some comboboxes boundto the input parameters for the flow, a button that is bound to an operation exposed by the web service and a table binded to the return of the web service.
The problem is that when i press the button, multiple instances of the SOA web services are created.
Can you please help with this problem?
Thanks,
Daniela

Daniela,
Are you executing the method programatically from bean? Can elaborate on what you mean by
The problem is that when i press the button, multiple instances of the SOA web services are created. Also, check out this blog on executing the method programatically by constructing the parameters to be passed.

Web Service triggering a Process Flow

Hi
I am a newbie to Oracle10g BPM. I am building a web application using Google Maps that would inturn invoke a BPM process.
From the Google Maps JSF web application i want to invoke a web service which in turn should do the required set of tasks(i.e geocoding and subsequent processing).
As such this is an application calling another BPM application.
The business logic is embedded in a web service(which forms the FIRST STEP) in the process. The web service is in turn expected to do a series of tasks which do not require any human intervention.
What i am NOT clear about is how to setup a Process flow that exposes a web service (at the first step) that can be consumed by external applications.
Can anyone give me broad guidelines on how i should be implementing this in BPM.
Thanks and Regards
Govind

This thread goes through step-by-step instructions on how to expose a process as a web service (PAPI-WS) working on both Studio and Enterprise:

Human task flow call back events with external web service

Hi All,
I have a requirement to call webservice inside human task flow. I have three participant in my human task flow. Let suppose A, B and C. When A approves then task will be assigned to B and when B approves it will go for C.
My requirement is that, when A approves , then i need to call one external webservice to update database. For this i have enabled call back events from human task flow.
In this way i got while loop inside my BPEL. In onTaskAssigned operation i am now trying to call external web service. My requriment is to call external service and get data from service. After getting response from the webservice, i want to assign it to next participant.
But in this case, when user B approves, it goes to onTaskAssigned block and i am able to make external web service also but mean time, it has been assigned to User C which i do not want.
I want Human task flow to wait for the web service response then only assign it to next participant.
Please help.
Regards,
Sunil

Hi Sunil
Have you tried using WebServices Adapter. The usecase seems pretty straight forward. You have a WebService that has some code and some Operations to update some Database. First thing, I hope you have methods/Operations defined with request and response xsd for each operation.
Now you define the main master payload, that should have all elements specific to your process and also few elements to store the output coming from each operation. Because response of each operation may need to go to other Task and get saved in the Payload also.
You have like 3 Tasks. To complicate, I will assume that each Task can either Approve or Reject. And last 2 Tasks gets data from payload, previous task and also output from the WebService Operation (method).
Task A -> Xor Gateway (Approve/Reject) -> If Approve -> Call WebServices Adapter -> Task B -> Xor Gateway(...) -> ......
At each intersection, you can map the attributes for incoming and outgoing. Based on WebServices output also, you can have Another XOR Gateway and decide to send to Task B or do something else. So combinations of outputs of each service (task or webservice adapter) and XOR gateways, you can have a decent control on the overall flow.
Note: I am hoping the webservices is Synchronous where you get the response immediately.
Let me know if I am missing something.
Thanks

Calling an External Web-Service Inside an Exception Flow

Hi all,
Is it a good practice in OBPM to call an External Web-Service when the process enters inside a System Exception Flow?

Your challenge will be when you throw an exception inside the Exception handler chain. You can't catch an exception (other than in a try/catch block in the logic of an Automatic activity) inside an Exception handler chain.
Sorry - not a good practice.

Web Services and data flow on Multicast

Need to find out a few options for how a Web Service application could send data (XML) to a multicast configuration (PIM).
I first thought about SOAP over some protocol like HTTP but wanted to get more input and ideas based on other experiences.
Also, what happens at the receiving end? Do I need a listening socket or something?
Any ideas or real-life experiences (even if not in a Multicast environment) are greatly appreciated!
Regards,
Arie.

Are you binding the data table component to the SearchResult[] array? Did you create a property for it in your page bean (.java file)?
Are you binding the different columns' components with the various getters from SearchResult[]?
For example, the binding should be of the form
#{currentRow.bookText} or #{currentRow.verseText}
etc.

Flow diagrams

Hi, I know that this question shoudn' t be on this forum but there are many people who can help me so please understand me.
I have developed an app for java and now I have to amke some flow diagrams like data flow diagrams (from level 0 to 2) system flow diagrams, state diagrams, transition diagrams (sorry if the name isn't correct in English).
What Im looking for is a web page or someting with information on how to do these diagrams (tutorials, examples, etc).
Thanks for your help. Bye!

UML 2.0 (Unified Modeling Language) is what you are looking for. Googling UML and/or the types of diagrams you need
should give you more hits than you can handle.
You can also check Safari, Amazon, etc. for many UML specific books, beginner and beyond.
Your forum transgression could be forgiven since it can be argued that being able to model the system you are trying
to design is a necessary skill for any programmer/engineer - Java or otherwise.
But in this case, I think it is especially relevant to Java since it is such a strongly object oriented language.
The only thing I would note is that the diagrams you are tasked with making should have been done before writing the app.

I can't find it either. Pratgeek, what was the name of the application you used in Ubuntu? Is there a website for it?
probably a kind of necrobump, but i've been searching for flowchart drawing software, and found this topic.
well, mentioned tdfd is the part of software suite called TCM available at least in debian/ubuntu.
it appears to be really old, i could found only user guide and ubuntu/debian package pages on the web, but it appears to be working quite well.
i've installed it on my ubuntu machine just half an hour ago, but it seems to be at least worth to play with, and i'd even make a PKGBUILD if i like it.

Remote BPEL Flow Diagram

Is there a way to show the BPEL Instance Flow diagram that is shown on BPEL Console , on my custom web application using some sort of API (if available)?
Thanks,

Hi,
ADF does not provide a component to draw diagrams at runtime. There will be a diagrammer component in a future version, but this also will be data driven. So the suggestion is to search for a web component that can do it ans embed it in ADF as an inlineFrame

How Can I include a logical data model in a Data Flow Diagram?

Hi,
I have done a logical data model and now, I want to include it in a data flow diagram. I do not know which element I should use to make this relation.
Thanks,

Hi,
you need to create "Information structure" in the flow properties dialog and then can assign attributes to that information structure in its properties dialog
