Web Services and the Portal

Are there any versions of the portal that have native support for communications to Web Services? Is it going to be eventually possible to dynamically discover channels via a discovery method like UDDI?

Currently no, in the next release we have preliminary support for web services and there might be web services provider but eventually no time frame yet we do plan to support UDDI ..

Creating Web Services in the Portal

Hi Experts,
I'm trying to create a Web Service in the portal based on a URL. However I am having some issues with the User Management settings. I've explained below the steps I've followed in order to setup the Web Service and the issue I am having.
I go to System Administration -> System Configuration -> System Landscape then I select my folder and right click. I then select New -> System (from template).
I then select "Web Service System using WSDL URL" and insert the URL for my Web Service. The issue I am then having is that when I access the User Management page I can only choose "NONE" or "UIDPW" as the Logon Method. However, I need to choose SAPLOGONTICKET which should be one of the options but isn't.
Does anyone know why this last option is not being displayed and how to fix this issue?
Thank you,
Kind Regards,
Ale

Create Web Service within the Portal

Hi, all.
I want to use SAP Portal for generating Portal web services on a base of some external procedures.
But to use NWDS in such way as to implement this procedure in EJB and create a web service for it seems not the best solution for me.
Are there any other ways to do it? For example, are there any utilities that can help me to generate a web service within the Portal?
Regards, Sergey.

MDM web services and the MDM BP services

Hi *,
I need to know what is the difference between the standard MDM web services and the MDM BP services. How do I decide which set to use?
- Kris

Sorry but what are BP services? Do you mean Business package?
If yes the approaches are completely different - you use Web Services when you have to customise the application and build your logic/functionality into the app. CRUD operations are procided by Web Services - you need to form your wrapper application from scratch and develop!
With BP - it involves least development effort bearing in mind that its all standard content and not yet completely customizable. So based on your requirements plan whether to go for Business Package or Web Services or Java API completely...

not being able to understand where i made the mistake. mistake is in the code of web service end or in calling code?
help me to fix this issue. thanks

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.

Web Services and the Developer Mindset

"Web Services has all the makings of a home run. As a powerful integration platform, it moves the procedural-heavy complexities of building distributed apps into the realm of simple declarative transactions, while supporting location transparency. It is a powerful that removes the barriers erected by the discontinuity of geographic distance and cross-platform technical mismatches that have until now constrained the plumbing between heterogeneous networked applications.
Developers who feel lost in the labyrinth of hype they can turn to a new site http://www.webservicesfaq.com devoted to UDDI, WSDL,SOAP, ebXML, and so on.
Here they'll learn how, while Web Services complements J2EE superbly, it is also an excellent integration platform for .NET technologies, and in fact for the transparent interoperability between the two, and between any other architectures that support the new Web Services standards.

What is your question?

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

Transport Webi Reports and Web services as the backend of dashboards from BO Production to BO Development system

Hello Experts,
I am working on SAP BO 4.1. I have made several dashboards on top of web services ie;Web Service Method. I have 2 systems in BO ie; Development and Production Systems.The BW production system is connected to BO Development and Production both.
The Webi reports are made on top of BI BEx Query. From the webi reports, BI Web Services are made on top of which the dashboards are made further.
The Webi Reports, Web Services and the Dashboards everything is made directly in BO Production.
My question is, Can I transport the Webi Reports and the Web Services from BO Production to BO Development?
And If yes, will it have any other impact on webi reports, web services or dashboards?
Thanks & Regards,
Alfred Thomas

Hi Gill,
As per your reply,with the promotion managament i have make the web services again manually in Dev system...Right?
Is there any way possible that i can transport the webservices and the webi reports usind Query AS A Web Service Designer. And if yes, through this QAAWS will the WSDL or the URL required for the web services in the connection button in dashboards will automatically updated or changed as per the Development System?
But i am not able to enable the "Deploy to Other servers Option" in QAAWS.
Can you please help?

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,
kc64

Web Services and Portal v1

Can 9iAS Portal v1 support Webservices just like Portal v2 can?

Yes ... I doubt the PDK samples built in V1 are backwards compatible because V1 used Apache JServ and V2 uses OC4J. I did build a demo for Oracle OpenWorld 2001 that showed this by building a stub in JDeveloper consuming the Web service and then building a portlet using the JPDK that used that Java stub to call a Web service. I did it on 9iAS Portal 1.0.2.2 and it worked fine. Not sure if that's all you're looking for ... I could send you the basic stuff offline but it is a little old and folks familiar with it are probably not so many now. So bear that in mind - [email protected]

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
Philippe

Are there any shortcuts to connecting the printer with web services and/or the eprint server?

(HP Officejet Pro 8600 Plus, IE, Windows 7)
As I am unable to execute the instructions given by
by Ryamond 1411, I'm looking for other avenues to connect my printer to web services and/or
the eprint server so I can release 4 emails for printout now stuck in que.

Hello MurrayJ,
The first thing I would do is follow step six in this document to set a static IP: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02817031&cc=us&dlc=en&lc=en&product=4023246&tmp...
When it askes for DNS information, enter in Google's DNS. Preferred DNS = 8.8.8.8 Alt DNS = 8.8.4.4
If that does not help, if you could provide me with the following information it would help me out. First, who is your ISP( Internet Service Provider, i.e. Comcast, AT&T, Verizon, ect.)? Second, who is the maker of your router? Lastly, what is the model number and firmware version of your router?
-------------How do I give Kudos? | How do I mark a post as Solved? --------------------------------------------------------

My envy 110 works but the web services and eprint services give "connection error". what to do?

My family use Macs and Apple Deskbook and a BT Homehub network. The HP troubleshooting instructions do not always match what is on computer screen. The menu paths that HP gives sometimes do not exist.
The Envy 110 printer was working fine but it often could not be found by the computers so I followed HP instructions to set a Static IP Address on the Printer. But now the Web Service and ePrint Service give a "connection error". Any suggestions? I am annoyed that HP don't give a phone number to help.

When you set that static IP on the printer, make sure of 2 things:
1. The IP address is outside the DHCP range of the router.
2. Use an external DNS, like Google DNS: 8.8.8.8 and 8.8.4.4
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.
I am employed by HP
