This example uses a portal component which opens a connection to a repository running on MDM Server,
retrieves data from the repository, and closes the connection.
There are 5 steps we will implement:

  1. Set the connector libraries in the deployment descriptor file portalapp.xml
  2. Open a connection to a repository
  3. Get the physical connection via the native interface
  4. Get data from a repository
  5. Close the connection

Step 1: configure the potalapp.xml file
The MDME Connector uses the SAP Connector Framework and MDME4J libraries as a shared library.
You need to add these libraries into portalapp.xml.

&ltapplication>
&ltapplication-config>
&ltproperty name="SharingReference"
value="com.sap.portal.pcd.glservice, com.sap.portal.ivs.connectorservice,
SAPJ2EE::library:MDME4J"/>
</application-config>
</application>

Step 2 : Open a connection to a repository (using the connector gatway service)

The useful EP6 features of system object aliases and single=sign-on user mapping are available

only by using the Connector Gatway Services approach.

// Get the Connector Gateway Service 
IConnectorGatewayService cgService = (IConnectorGatewayService)
PortalRuntime.getRuntimeResources().getService( IConnectorService.KEY);

// Create ConnectionProperties for portal user
ConnectionProperties prop =
new ConnectionProperties(request.getLocale(), request.getUser());

// Get a connection
IConnection connection =
cgService.getConnection("MDME_SYSTEM_ALIAS_NAME", prop);

Step 3: Get the physical connection via the native interface

Retrieve the native interface from the connection, and invoke getNative method.

// Retrieve Native inteface
INative nativeInterface = connection.retrieveNative();

// Get the CatalogData the physical connection
CatalogData catalog = (CatalogData)
nativeInterface.getNative(CatalogData.class.getName());

Step 4: Get data from a repository

All methods of the CatalogData object are available for retrieving data.

The following code uses the GetResultSet method as an example.

// Create ResultSetDefinition for products table
ResultSetDefinition rsd = new ResultSetDefinition("Products");
rsd.AddField("Name");

// Create Search for products table
Search search = new Search("Products");

// Get Data from table
A2iResultSet rs = catalog.GetResultSet(search, rsd, "Name", true, 0);

Step 5:Close the connection

connection.close();
