public ConfigBasedEJBClientContextSelector(EJBClientConfiguration ejbClientConfiguration)

Creates a ConfigBasedEJBClientContextSelector using the passed ejbClientConfiguration.

This constructor creates a EJBClientContext and uses the passed ejbClientConfiguration to create and associated EJB receivers to that context. If the passed ejbClientConfiguration is null, then this selector will create a EJBClientContext without any associated EJB receivers.

Parameters:

ejbClientConfiguration - The EJB client configuration to use

Creates a ConfigBasedEJBClientContextSelector using the passed ejbClientConfiguration.

This constructor creates a EJBClientContext and uses the passed ejbClientConfiguration to create and associated EJB receivers to that context. If the passed ejbClientConfiguration is null, then this selector will create a EJBClientContext without any associated EJB receivers.

Parameters:
