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 throwing a 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.

  • Method Details

    • getDestinationInstance

      protected abstract JCoDestination getDestinationInstance(String destinationName, String scopeType) throws JCoException
      Do not use this method. Reserved for internal use. Use getDestination(String) or getDestination(String, String) instead.
      Parameters:
      destinationName - the name of the destination for which a JCoDestination instance shall be returned
      scopeType - the name of the scope to which the destination shall belong to
      Returns:
      a JCoDestination instance that matches the destination name
      Throws:
      JCoException - if the specified destination does not exist or could not be created
    • 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 shall be returned
      Returns:
      a JCoDestination that matches the destination name.
      Throws:
      JCoException - if the specified destination does not exist or could not be created
    • 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 shall be returned
      scopeType - the name of the scope to which the destination shall belong to
      Returns:
      a JCoDestination instance that matches the destination name.
      Throws:
      JCoException - if the specified destination does not exist or could not be created
