Connect to R/3 with the connector framework

Hi,

Sure...

public static IConnection getConnection(String sapSystemAlias,

IPortalComponentRequest componentRequest)

throws IllegalArgumentException {

// check if passed attributes are null

if (componentRequest == null) { throw new IllegalArgumentException(

"IComponentRequest object can not be null!"); }

if (sapSystemAlias == null) {

// use default system alias

//sapSystemAlias = defaultSAPSystemAlias;

}

ILogger logger = PortalLog.getLogger();

com.sap.security.api.IPrincipal user = componentRequest.getUser();

Locale locale = componentRequest.getLocale();

ConnectionProperties properties = new ConnectionProperties(locale, user);

IConnection connection = null;

try {

IConnectorGatewayService connectorGatewayService = (IConnectorGatewayService) PortalRuntime

.getRuntimeResources().getService(IConnectorService.KEY);

connection = connectorGatewayService.getConnection(sapSystemAlias,

properties);

} catch (Exception e) {

logger.severe(e, "Exception while creating a connection.");

}

return connection;

}

It makes also sense to have a central method to close connections...

public static boolean closeConnection(IConnection connection) {

boolean succesful = false;

if (connection != null) {

try {

connection.close();

succesful = true;

} catch (ResourceException re) {

PortalLog.getLogger().severe(re,

"Connection to SAP could not be closed!");

}

}

return succesful;

}

and interactions...

public static boolean closeInteraction(IInteraction interaction) {

boolean success = false;

if (interaction != null) {

try {

interaction.close(); // close interaction

success = true;

} catch (Exception e) {

String message = "Exception closing interaction.";

PortalLog.getLogger().severe(e, message);

}

}

return success;

}

Regards,

Kai
