Connect to SAP Netweaver Gateway in SpagoBI

Create reports featuring live SAP Netweaver Gateway data in SpagoBI Studio. Host SAP Netweaver Gateway reports on SpagoBI Server.

The CData JDBC Driver for SAP Netweaver Gateway enables you to connect to live SAP Netweaver Gateway data from business intelligence and data mining tools that support the JDBC standard. This article shows how to integrate SAP Netweaver Gateway data into a report in SpagoBI Studio and host it on SpagoBI Server.

Deploy the JDBC Driver in SpagoBI Server

Follow the steps to create a JDBC data source for SAP Netweaver Gateway in SpagoBI Server.

  1. Copy the driver JAR into %CATALINA_BASE%/lib. These files are located in the lib subfolder of the installation directory.
  2. Add a SAP Netweaver Gateway driver resource to the context. The following resource definition can be added to the GlobalNamingResources element in server.xml: <Resource name="jdbc/sapgateway" auth="Container" type="javax.sql.DataSource" driverclassname="cdata.jdbc.sapgateway.SAPGatewayDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" maxactive="20" maxidle="10" maxwait="-1"/>

  3. Add the following resource link to give access to Web applications. For this article, add the following line to META-INF\context.xml for SpagoBI. <ResourceLink global="jdbc/sapgateway" name="jdbc/sapgateway" type="javax.sql.DataSource"/>
  4. Restart the server.

After adding the driver to the resources for the SpagoBI server, add the data source: In SpagoBI, click Resources -> Data Source -> Add and enter the following information:

  • Label: Enter a unique identifier for the driver.
  • Description: Enter a description for the driver.
  • Dialect: Select Default Dialect.
  • Read Only: Select the read-only option. This option determines whether the data source is the default database to save datasets created by the end user.
  • Type: Select JDBC.
  • URL: Enter the JDBC URL using the required connection string 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.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the SAP Netweaver Gateway JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.sapgateway.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    A typical JDBC URL is below:

    jdbc:sapgateway:User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/;InitiateOAuth=GETANDREFRESH
  • Driver: Enter the class name for the driver: cdata.jdbc.sapgateway.SAPGatewayDriver

Create Reports in SpagoBI Studio

Follow the steps below to populate reports based on SAP Netweaver Gateway data in SpagoBI Studio. You will create a dataset that populates a chart with the results of an SQL query. In the next section, you will host this report on SpagoBI Server.

First, you will need to connect to SAP Netweaver Gateway data from a report in SpagoBI Studio:

  1. In SpagoBI Studio, click File -> New -> Project and select Report Project in the Business Intelligence and Reporting Tools folder.
  2. Click File -> New -> Report and select Blank Report.
  3. In the Data Explorer view, right-click Data Sources and click New Data Source.
  4. Select JDBC Data Source and enter a name for the data source.
  5. Click Manage Drivers and click Add to add the driver JAR, cdata.jdbc.sapgateway.jar. The driver JAR is located in the lib subfolder of the installation directory.
  6. In the Driver Class menu, select the driver class, cdata.jdbc.sapgateway.SAPGatewayDriver.
  7. In the Database URL box, enter the JDBC URL. A typical JDBC URL is below: jdbc:sapgateway:User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/;InitiateOAuth=GETANDREFRESH See the "Getting Started" chapter of the driver help for a guide to obtaining the required connection properties.

After you have connected to SAP Netweaver Gateway data, create a dataset that contains the results of an SQL query:

  1. Right-click the DataSet folder and click New Data Set. Select the JDBC data source for SAP Netweaver Gateway and enter a name for the dataset.
  2. Build the SQL query. In this example, this query will be used to add a chart to the dashboard. For example: SELECT ProductID, Quantity FROM SalesOrderLineItems WHERE Quantity < 15

You can use the dataset to populate report objects. Follow the steps below to create a chart.

  1. In the Palette view, drag a chart onto the canvas.
  2. In the Select Chart Type tab, select a bar chart.
  3. In the Select Data tab, click the Use Data From option and select the SAP Netweaver Gateway data set from the menu.
  4. Drag ProductID from the table to the series for the x-axis.
  5. Drag Quantity from the table to the series for the y-axis.

Host SAP Netweaver Gateway Reports on SpagoBI Server

Follow the steps below to host documents based on live SAP Netweaver Gateway data on SpagoBI Server. You will use the report you created in the previous section as a template. To enable report users to access the live data, create placeholder parameters to be replaced by the SAP Netweaver Gateway JDBC data source on the server:

  1. If you have not already done so, open the Report Design perspective in SpagoBI Studio.
  2. In the Data Explorer view, right-click the Report Parameters folder and click New Parameter. Add the url parameter and assign an empty value to it. This parameter is a placeholder for the JDBC data source on the SpagoBI Server.
  3. Right-click the SAP Netweaver Gateway data source and click Edit.
  4. In the Property Binding node, set the JDBC Driver URL binding property to the url parameter: Click the box for the property. In the Category section, select Report Parameters. Select All in the Subcategory section and double-click the parameter.

    You can also enter the following in the JavaScript syntax:

    params["url"].value

Next, create a new document for the report on SpagoBI Server.

  1. In SpagoBI Server, click Documents Development -> Create Document -> Generic Document. The Document Details page is displayed.
  2. To create the document, enter the following:
    • Label: Enter a unique identifier for the document.
    • Name: Enter a user-friendly name for the document.
    • Type: Select Report from the menu.
    • Engine: Select BIRT Report Engine.
    • Data Source: Select the SAP Netweaver Gateway Data Source you created in Create a JDBC Data Source for SAP Netweaver Gateway in SpagoBI Server.
  3. In the Show Document Templates section, select the folder where you want the document to be stored.
  4. In the Template section, click Choose File. Navigate to the folder containing your report project. Select the .rptdesign file.

    Note: You can find the path to the project in the project properties.

  5. Click the Save button.

When you run the report on the server, the placeholder url parameter is replaced with the JDBC URL defined on the server.
