Today is my first day in this forum. I am a Windows Phone Developer, and want to know how can I start with SAP NetWeaver Gateway so that I can consume data from SAP Server in my Windows Phone Apps.
Thanks for your reply. Actually today is my first day in SAP community so probably I don't have a ready answer for your question like the middleware. But I can put some points which might help you connect and get your answer. We have a backend server(SAP) now the requirement is : 1. Build a Windows Phone app which will consume the data from the SAP server During discussion few terms which are heard is 1. Middleware 2. SAP NetWeaver Gateway. Which brings me to landed in the SAP community. The Service that we need to consume in our windows phone app looks like
As mentioned earlier , Netwerver gateway is used to develop Odata services . Odata is an open protocol where any platform can comsume it and develop applications on top of it.
Assuming you are developing for Windows Natively( amy be Windows 7, 7,1 / Windows 8 )
Applications can be developed Directly consuming Odata services (or) Via SMP
i.e Netweaver Gateway --> Odata Services --> Application development consuming services (C# visual Studio )
Yes, I am using OData, and trying to develop native app for Windows Phone 8 platform. Now should I use SMP or something else like " Microsoft OData Client for Windows Phone"
I am trying to access the below link, do I need to be in their network to access their server. Because with a GET web request I am getting "Remote server not found".
Is myserver.com associated with public IP or a private IP address ?
Are you able to connect to the system ? When you try from any browser with this url in address box ,are you able to fetch any data / prompted for credentials ?
When I try to put this url in desktop web browser I get the bellow message.
"
Unknown Host
Description: Unable to locate the server named "servername.com" --- the server does not have a DNS entry. Perhaps there is a misspelling in the server name, or the server no longer exists. Double-check the name and try again.
And when I try to request this URL from my mobile device I get "Remote server not found"
** Is this gateway services / URL generated in your local environment ?
This is something i would do if i face a similar error :
1) Ensure corporate/local firewall allows me to deploy and activate the application
2) If the Netweaver Gateway is in a local environment , then add the server IP in the host of the local system from where the system is to be accessed
To edit the hosts file
C:\Windows\system32\drivers\etc\hosts
in Windows 7, you need to run the editor (eg. notepad) as administrator, which you do by locating it through the Start menu and then right clicking on the editor's icon, then manually open and edit the hosts file.
Please check if you are able to connect to the remote server DNS which developed the OData Service . check if the port being used is unblocked and you are able to connect to the system.
What is 'Netweaver Gateway" Do I need to install any software in my local system to complete this task.
The odata URL you are using might be generated by Netweaver Gateway or any other applications like JAM / Enterpise Portal / any which has capabilities to generate Odata Services.
If Odata Services are generated from a remote location that does nt imply to install the software which helped to develop odata service.
But its important to make sure that you can connect to the server which has generated the Odata Service .
The above is a demo service offered as a sample-- > developed by some person from a remote location. Any developer can consume this service and develop an application consuming this service.
If this URL is opened from a browser , the data is displayed either in JSON/ XML format.
Its to be noted that the developer has access to the server and successfully connected with the server . (the sample servicein this case might be mapped with a public URL)
**please check if you are able to connect to their server DNS which has developed the odata service.
** Your network team / basis team might help you with a safe connection (VPN / proxy / some other means )
3. If I get the access to the remote server I am trying to connect, can I use Odata Client Tools for Windows Phone Apps for my development or I need some other tools as well.
The best thing about Netweaver Gateway is to generate OData services, and any newbie to SAP and knowledge in mobile application development can develop applications consuming these services.
If I get the access to the remote server I am trying to connect, can I use Odata Client Tools for Windows Phone Apps for my development or I need some other tools as well.
Once Odata Services are generated from SAP Netweaver Gateway, the consumption of the services to Windows Phone becomes a regular Windows Native development approach( using C# , VB) and you may not need any specific tools from SAP for this.
But for windows Mobile Application you may need to meet its prerequisites
Please check if expected data is obtained with these extensions before the development process.
Can I access the remote server using the Odata Client Tools for Windows Phone Apps like I did in
You may not need access over the complete remote server , but permissions to connect to the server , fetch the data. If you are performing any CRUD operations then these permissions are provided.
**Remote Server : Its the connection to Netweaver Gateway ( credentials and connection properties) which is needed but not the windows server in which netweaver gateway is installed.
There is also a demo system available from SAP for Gateway and consume sample OData services.
Are you using SUP/ SMP here ? (this is optional but recommended)
I appreciate your help, you have been trying to guide me in so many ways, but I think as I don't have the access to the SAP service so I am not able to get the data. by the way I have tried few steps.
GWPAM is an interoperability framework from SAP that leverages SAP NetWeaver Gateway and Microsoft technologies enabling customers and partners to easily and quickly compose solutions that consume and extend SAP throughout Microsoft technologies for on premise and on demand deployment.
