Access Live SAP Netweaver Gateway Data in TIBCO Data Virtualization

TIBCO Data Virtualization (TDV) is an enterprise data virtualization solution that orchestrates access to multiple and varied data sources. When paired with the CData TIBCO DV Adapter for SAP Netweaver Gateway, you get federated access to live SAP Netweaver Gateway data directly within TIBCO Data Virtualization. This article walks through deploying an adapter and creating a new data source based on SAP Netweaver Gateway.

With built-in optimized data processing, the CData TIBCO DV Adapter offers unmatched performance for interacting with live SAP Netweaver Gateway data. When you issue complex SQL queries to SAP Netweaver Gateway, the adapter pushes supported SQL operations, like filters and aggregations, directly to SAP Netweaver Gateway. Its built-in dynamic metadata querying allows you to work with and analyze SAP Netweaver Gateway data using native data types.

Deploy the SAP Netweaver Gateway TIBCO DV Adapter

1. In a console, navigate to the bin folder in the TDV Server installation directory. If there is a current version of the adapter installed, you will need to undeploy it.

   .\server_util.bat -server localhost -user admin -password ******** -undeploy -version 1 -name SAPGateway
   

2. Extract the CData TIBCO DV Adapter to a local folder and deploy the JAR file (tdv.sapgateway.jar) to the server from the extract location.

   .\server_util.bat -server localhost -user admin -password ******** -deploy -package /PATH/TO/tdv.sapgateway.jar
   

You may need to restart the server to ensure the new JAR file is loaded properly, which can be accomplished by running the composite.bat script located at: C:\Program Files\TIBCO\TDV Server <version>\bin. Note that reauthenticating to the TDV Studio is required after restarting the server.

Sample Restart Call

.\composite.bat monitor restart

Authenticate with SAP Netweaver Gateway Using OAuth

Since SAP Netweaver Gateway authenticates using the OAuth protocol and TDV Studio does not support browser-based authentication internally, you will need to create and run a simple Java application to retrieve the OAuth tokens. Once retrieved, the tokens are used to connect to SAP Netweaver Gateway directly from the adapter.

The following code sample shows how to authenticate with SAP Netweaver Gateway. You will simply need to execute the Java application with the tdv.sapgateway.jar file in the class path.

SAPGatewayOAuth oauth = new SAPGatewayOAuth();  
oauth.generateOAuthSettingsFile("InitiateOAuth=GETANDREFRESH;" + 
                                  "User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/;" + 
                                  "OAuthSettingsLocation=C:\sapgateway\OAuthSettings.txt;");

Once you deploy the adapter and authenticate, you can create a new data source for SAP Netweaver Gateway in TDV Studio.

Create a SAP Netweaver Gateway Data Source in TDV Studio

With the CData TIBCO DV Adapter for SAP Netweaver Gateway, you can easily create a data source for SAP Netweaver Gateway and introspect the data source to add resources to TDV.

Create the Data Source

1. Right-click on the folder you wish to add the data source to and select New -> New Data Source.
2. Scroll until you find the adapter (e.g. SAP Netweaver Gateway) and click Next.
3. Name the data source (e.g. CData SAP Netweaver Gateway Source).

4. Fill in the required connection properties.

   SAP Gateway allows both basic and OAuth 2.0 authentication. You can use basic authentication to connect to your own account, or you can use OAuth to enable other users to retrieve data from your service with their accounts. In addition to authenticating, set the following connection properties to access SAP Gateway tables.

   • Url: Set this to the URL of your environment, or to the full URL of the service. For example, the full URL might appear as: https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/. In this example, the environment URL would just be: https://sapes5.sapdevcenter.com.
   • Namespace: Set the appropriate Service Namespace. In the example above, IWBEP is the namespace. It is optional if the full URL to the service is specified.
   • Service: Set this to the service you want to retrieve data from. In the example above, the service is GWSAMPLE_BASIC. It is not required if the full URL is specified.

   Authenticate via Basic Authentication

   In basic authentication, you use your login credentials to connect. Set the following properties:

   • User: This is the username you use to log in to SAP Gateway.
   • Password: This is the password you use to log in to SAP Gateway.

   Authenticate via OAuth Authentication

   You can connect to SAP Gateway using the embedded OAuth connectivity (without setting any additional authentication connection properties). When you connect, the OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

   NOTE: Set the OAuthSettingsLocation property in the DV Adapter to the same value you used when performing the OAuth authentication (see above).

5. Click Create & Close.

Introspect the Data Source

Once the data source is created, you can introspect the data source by right-clicking and selecting Open. In the dashboard, click Add/Remove Resources and select the Tables, Views, and Stored Procedures to include as part of the data source. Click Next and Finish to add the selected SAP Netweaver Gateway tables, views, and stored procedures as resources.

After creating and introspecting the data source, you are ready to work with SAP Netweaver Gateway data in TIBCO Data Virtualization just like you would any other relational data source. You can create views, query using SQL, publish the data source, and more.
