Class JCoDestinationManager

java.lang.Object
  com.sap.conn.jco.JCoDestinationManager

public abstract class JCoDestinationManager
extends Object

The JCoDestinationManager creates and manages the destinations used by JCo applications. The APIs are static and can be invoked directly.

Note: A destination instance may become invalid if the destination configuration is changed or removed. In such cases the running operation will be finished but the further usage of the invalidated destination will be blocked by JCoException with the key JCO_ERROR_DESTINATION_DATA_INVALID. The application may fetch an updated destination instance from JCoDestinationManager if it is suitable for the application scenario.

Constructor Summary

static JCoDestination	getDestination(String destinationName) Call this method to get an instance of a destination, on which you need to execute a function module.
static JCoDestination	getDestination(String destinationName, String scopeType) Call this method to get an instance of a destination, on which you need to execute a function module.

Method Detail

getDestinationInstance

protected abstract JCoDestination getDestinationInstance(String destinationName,
                                                         String scopeType)
                                                  throws JCoException

Reserved for internal use. Use getDestination(String) or getDestination(String, String) instead.

Throws:

JCoException

getDestination

public static JCoDestination getDestination(String destinationName)
                                     throws JCoException

Call this method to get an instance of a destination, on which you need to execute a function module.

Parameters:

destinationName - the name of the destination for which a JCoDestination instance will be returned

Returns:

a JCoDestination that matches the destination name.

Throws:

JCoException - with the key JCoException.JCO_ERROR_RESOURCE, if the specified destination does not exist

JCoRuntimeException -

• with the key JCoException.JCO_ERROR_CONFIGURATION, if the destination configuration or environment is not configured properly.
• with the key JCoException.JCO_ERROR_DATA_PROVIDER_ERROR, if the destination data provider was not able to lookup the destination configuration

getDestination

public static JCoDestination getDestination(String destinationName,
                                            String scopeType)
                                     throws JCoException

Call this method to get an instance of a destination, on which you need to execute a function module. The scopeType parameter allows to assign all stateful operations done on this destination to a certain scope in runtime environments that differentiate between several scopes within a session. Whether the runtime environment really supports scopeTypes, depends on the session and/or scope management. Actually, it defines whether scopeTypes are actually needed, and will reflect that in the implementation of the SessionReferenceProvider. If scopeTypes are not supported the parameter scopeType will be ignored and you could always use the method getDestination(String destinationName). If scopeTypes are supported, the valid scopeTypes are defined by the session management of the runtime environment.

Parameters:

destinationName - the name of the destination for which a JCoDestination instance will be returned

scopeType - the name of the scope to which the destination should belong to

Returns:

a JCoDestination that matches the destination name.

Throws:

JCoException - with the key JCoException.JCO_ERROR_RESOURCE, if the specified destination does not exist or contains invalid values
