Method Detail

getService

public TranscodingService getService(java.util.Properties config)
                              throws javax.naming.ServiceUnavailableException

Returns the remote or local EJB service looked up with the given JNDI properties. Actually only the properties prefixed with ejb. will be taken into account (with the prefix removed).

If EJB_LOCAL_PARAM is present and set to true the local EJB service will be retrieved. Otherwise the method looks up the remote EJB service and wraps it with a proxy, which attempts to reconnect the transcoding server is case of a connection breakdown (tested on Glassfish v2 & JBoss 4.2.X).

Specified by:

getService in interface TranscodingServiceLocator

Parameters:

config - JNDI and configuration properties

Returns:

service's EJB stub

Throws:

javax.naming.ServiceUnavailableException - if the service cannot be contacted
