Web services and message ordering

i am a newbie to Rest services and camel. please help me. message(xml)will be sent from services at endpoint 1 to services exposed @ endpoint 2. i am not going to use queue or anything in between. but i want message ordering for few instances. so how is it possible. is there any option available. thanks

thanks for the response.
I dont wait for response 1 before sending request 2 and thats why am asking qn on how to preserve order. communication is not synchronous. i send multiple messages to different threads and i will not know the order across the whole message stream as each thread will process messages concurrently.
For example i will be sending message 1 and message 2 which should go in order. For some reason if message 2 goes before message 1 my whole requirement will fail. if i use queue in between i can preserve the order but am not going to use queue. so is there anything i can do to ensure that message 1 goes before message 2?

Need info on Standard Web services to pull Order data in CRM from external applications

Hi Gurus,
I have a requirement to pull Order data in CRM from external non-sap application using Web services. Are there any standard SAP provided web services to pull order data based on some input? If yes, can you provide me any kind of documentation related to this?
Appreciate your help on this.
Thanks

Diff b/w Web service and window service

What is the difference between web service and window service, whether the both are same or not, Give some explain about that each one and give some examples also.

An XML Web service is a component that implements program
logic and provides functionality for diseparate
applications. These applications use standard protocols,
such as HTTP, XML, and SOAP, to access the functionality.
XML Web services use XML-based messaging to send and
receive data, which enables heterogeneous applications to
interoperate with each other. You can use XML Web services
to integrate applications that are written in different
programming languages and deployed on different platforms.
In addition, you can deploy XML Web services within an
intranet as well as on the Internet. While the Internet
brings users closer to organizations, XML Web services
allow organizations to integrate their applications.
A Windows service starts much before any user logs in to
the system (if it has been setup to start at boot up
process). A Windows service can also be setup in such a way
that it requires a user to start it manually ? the ultimate
customization!
Windows services run as background processes. These
applications do not have a user interface, which makes them
ideal for tasks that do not require any user interaction.
You can install a Windows service on any server or computer
that is running Windows 2000, Windows XP, or Windows NT.
You can also specify a Windows service to run in the
security context of a specific user account that is
different from the logged on user account or the default
computer account. For example, you can create a Windows
service to monitor performance counter data and react to
threshold values in a database.

Hi Mou,
I just tried your win app code about calling web service, but failed. I got the 500 error after I called your service:
The error message I quoted from Fiddler:
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><faultcode>soap:Client</faultcode><faultstring>System.Web.Services.Protocols.SoapException: Failed : Invalid credentials ---> System.Exception: Invalid credentials

I am not totally sure that error occurred by the authentication. But I suggest you can try to add this service into your project using this method below:
1.right click the Reference and select Add Service Reference
2.input your service link and click "Go"
And you can use this service as the following:
private async void callService()
ServiceReference1.SearchDataIndexSoapClient client =new ServiceReference1.SearchDataIndexSoapClient();
var Str= await client.StartIndexAsync(new ServiceReference1.AuthHeader { Username = "Admin", Password = "Admin" });
Please try it.

SQL Server 2008 Reporting Project - Invoke/Consume Web Service and Return Dataset in C# Code-Behind

Hello,
I have a Visual Studio 2010 C# class with a method that invokes/consumes a web service and returns an XML dataset. I am traversing through the parent/child nodes and parsing out the data then inserting it into a SQL Server 2008 R2 table for a join within
another stored procedure.
Instead of using a 3rd party API to generate the PDF for this data, I am creating an SSRS report. The formatting will be easier and I can do a RenderFormat directly to PDF.
Can I expect to be able to transfer the code-behind method to this report and have it be able to work with the web service the same way? It is a SOAP-based web service returning parent nodes and two levels of nested child nodes.
I have also been researching the approach of calling the web service in the same stored procedure that is currently querying the physical tables (which is used to populate a gridview and PDF) but it looks like it may only be possible with a CLR stored procedure.
Is it possible to implement a CLR stored procedure within an SSRS report?
Hope this makes sense. Any help, suggestion or point in the right direction would be greatly appreciated.
Thanks,
Buster

Hi Buster,
SSRS supports web service data source, we can call the SOAP-based web service in SSRS report directly. Then, we can use custom code in SSRS to parse the XML data. However, we won’t be able to join another data in SQL Server database.
Reference:http://technet.microsoft.com/en-us/library/aa964129(v=sql.90).aspx#repservxmlds_topic3
We cannot implement a CLR stored procedure within an SSRS report directly. In order to execute the CLR store procedure in a SSRS report, we have to execute it as text using the following code:
Exec <stored procedure name>
Reference:

Web services and control characters

Hi,
We are using JAXWS and JAXB to create web services. We have a problem with our current data because it sometimes contains "bad" characters, such as control characters. Is there a nice way for us to remove these characters when creating the messages or when retrieving the data from the database? We use java persistence / hibernate to retrieve the data from the database.
I would prefer a method that doesn't include having to "clean" each string manually...
Thanks!

Best way to call web service from Message Driven Bean

I'm q'ing msgs up and would like to use a message driven bean to forward them to
an external web service. Weblogic workshop does not seem to support web service
controls in an EJB project. Any suggestions?
Thanks,
Paul

Paul,
A non-trivial alternative, since you have the WSDL, would be to forget about trying
to use generated client code and just use JAX-RPC dynamic invocation instead.
That's how I call external web services from within an EJB in situations in which
generated client code cannot be incorporated prior to deployment. Minimally all
that is required is the WSDL and the service name, port name, and operation name,
although if non-builtin parameter types are used then you will have to manipulate
the service's type mapping registry.

Could you not first use clientgen on the external webservice, then take

Web Services and JHS

My company is exploring the use of JHeadstart and we are very impressed with its capabilities. The enterprise environment into which our system will be deployed requires separation between the View Layer, and the Model Layer, with a SOAP-based messaging agent as the go-between (it's MQ series-based). We have been able to get a prototype plain-old UIX application to work where we deploy the Application Module in the Model project as a web service, and then create a data control from the stub to consume in the UIX ViewController project. We can then simply drag and drop the Web Service call result sets onto the UIX pages. However, when trying to do this with JHeadstart, the Wizard for creating Application Structure Files requests an Application Module on one of the first screens. In our environment, we won't be able to allow the ViewController project to see the Model project. Is there any way to use a web service instead of the Application Module? If not, is there any plan to support this type of activity in a future JHS release?
Thanks in advance,
Dan Schiff

Dan,
Currently JHeadstart only supports ADF Business Components as the Business Service layer (directly accessed, not through a Web Service wrapper). As you found out, ADF supports other Business Services as well, not only Web Services but also TopLink, EJB, etc.
JHeadstart is primarily intended for data manipulation (select, insert, update, delete) and our philosophy is that that type of functionality (that part of your application) is most efficiently handled directly by ADF Business Components. Also, this is the most productive technique for application developers. Of course, the end result of generating an application with JHeadstart is that you have a "normal" ADF application, to which you can add Web Service functionality with the normal JDeveloper visual editors and drag-and-drop features.
So you could generate efficient data manipulation screens using JHeadstart and direct ADF Business Components, and then add interoperability with other Business Services to your application using Web Services. The latter part is not JHeadstart-generated.
The next JHeadstart release (10.1.3) will be focused on supporting JSF (JavaServer Faces). We are also looking into support for other Business Services like TopLink, but we don't have any schedule for that yet.

SOAP Reliable Messaging (8.1) vs. Web Service Reliable Messaging (9.0)

I am looking for the differences in implementation and user experience for two Reliable Messaging solutions ( besides that WL 9.0 implemented WS-RM Spec. ). In particular, when a Reliable Messaging transaction is committed and successfully complete, which consumer element/component on the receiver side gets the message and how ( I mean a run-time component which is not implemented by WL on the receiver side) ? Does the message stay in receiver side persistent storage until it is taken by the consumer element/component or it sits in memory only ?
Docs in 8.1 version detailed how the SOAP RM worked while in 9.0 version such description is absent.
Please, send your response to [email protected]
Thank you in advance,
- Michael

Hi,
i think its not possible to get the response of the return type as void. you just think in normal core java also, its not possible that. i think you must change in the web service. and one more thing are you developing the web service in java or .NET? if it in java its easy to change the return type. i am also new to java web service. i am giving what i know.
Thanks

Interfacing web services and RT applications

[First, sorry to the NI guys who helped me with this over the phone. It's not that I don't trust your input but in the multitude of counselors there is wisdom.]
If I want to interface my cRIO real-time control loop with the outside world using web services, how do you implement the interface between the web service and the RT app? If the RT app is included as part of the web service, will it start running at target boot time or must it be invoked using the web service?

Aaron--
What I have now is a web service only application--I only have one Build Specification and it is for the RESTful web service. I placed what typically would be my RT application code in the web service Source Files section without any URL mappings to go with it. Then I simply call the top level RT executable code from the web service by static reference and have it return without waiting for code execution to complete. At this point, my "RT app" is running on the cRIO and can communicate with the web service via functional globals.
The fact that my "RT app" does not run at boot time is not an issue in this application so I feel like I'm getting by on a special case. If I needed to run the RT application at boot time with headless operation, I think I would still be having a problem. I just find it a bit quirky that NI's web services put the developer in the situation that, in order to communicate with an RT executable, they must use shared variables (yuck) or implement a mini virtual network. Why not put the web service and the RT app into the same application space and be done with it?
Thanks,

Siebel OnDemand Web Services and BPEL II

We are trying to do a POC for a given client that is trying to decide between SOD and another on demand CRM product.
Our POC is to integrate SOD using bpel and sending data to a back end system with SOD as the originator and instigator of the flow.
We intend to take data from an integration event pull it into bpel do a transformation to add data to it and update SOD to complete the circuit.
We are having a few issues and was wondering if you can provide some insight since we would like to put SOD at this site.
Our issues are :)
Issue 1
When we import the WSDL for the Integration event the scheema's are not resolved.
Issue 2. When we import more than one WSDL in our flow it has issues with duplicates between the 2 wsdls..
issue 3.
We have succesfully used the example application to do our login and faked out the endpoint but have not been able to automate this step.
We found an example online at oracle ( http://www.oracle.com/technology/tech/fmw4apps/siebel/ofm-siebel-blog-postings.html)
(We got that link from the other BPEL post: Siebel OnDemand Web Services and BPEL
But when we copy the code into our embeded java object it doesn't work. I think that we may be missing some of the code to use.
Do we have the full copy of this java object?
here is hte error that we get from bpel
Exception reported is: Siebel_On_Demand.bpel:33: Class bpel.p0.URL not found.

I'm also trying to do this.
Some info from the Siebel web services guide:-
"The login request is an HTTPS request to instantiate a session and obtain a session ID. A client invokes login by sending an HTTP GET request to a URL like the following:
https://secure.crmondemand.com/Services/Integration?command=login
NOTE: The login parameter value is case sensitive.
■ Login input. The input to login is provided in the URL parameters and the HTTP headers, as follows:
■ The only URL parameter to be set is command. This parameter value is login.
Two HTTP headers, UserName and Password, must be set with the appropriate values for your system. For example:
❏ UserName: [email protected]
❏ Password: mypass
■ Login output. The login command returns the following items:
■ A session cookie, jsessionid. The client must use this cookie when submitting subsequent requests, including logoff requests.
■ A status code of 200, if the session does not encounter any errors. This indicates that the request succeeded.
Then to get data out ....
Integration request input. The jsessionid returned to the client during login must be included with the request. The request must contain the jsessionid either as a cookie or as a URL parameter, as follows:
https://secure.crmondemand.com/Services/Integration/object;jsessionid=xyZ12489w3482413
Does anyone have any ideas on how we might do this using the Oracle BPEL PM?
Thanks in advance.

Web service and servlets in the same project...web.xml?

Hello, I have a problem with my web service.
I have a server, which displays a web service. I programmed this service with JAXRPC.
I have a client, in another directory. I succeded in compiling, deploying and running the web service.
The problem is that after I tried to integrate this service in an existing project. This project contains servlets. In these servlets, I'm using sessions.
These servlets are on the same side as the server of the web service. Because of the implementation of my code, I'd like to use in the class that represents the server of the service, the same session as the one I'm using in the servlets.
But of course, it's not working by itself. I know there's something to do with the web.xml files.
The thing is that I created a web.xml file for the service, and another for the servlets.
I was thinking of joining both of them in one xml file, but everything crashes then...
Could someone tell me how to create a project with a web service and servlets, and mostly how to configure the xml file??
Thanks for any help

Quick questions on the topic of Web Services and EJB POJOs

I have been reading about Web Services and the data types that are aloud as operation parameters and return types. I was wondering what the standard practice for return types; is it to use the Entity classes straight and customize the WSDL instead of letting the EE container do it (avoid cyclic problems in the schema that can occur when using entity 1-to-many and many-to-1 mappings) or; is it to off load the data into a DTO/VO/Bean and let the EE container take care of all the schema mapping for the WSDL? I look at the EE tutorial and bought a EE book both use very basic examples that do not include connecting to a database or using EJB3 for the data store.
Thanks for any information
