A polling inbound endpoint polls periodically for data and when data is available the data is injected to a given sequence. For example,  the JMS inbound endpoint checks the JMS queue periodically for messages and when a message is available that message is injected to a specified sequence. Polling inbound endpoints support one way operations and are asynchronous.
