Blackberry push notification implementation

How does one implement a push notification for a bl开发者_开发技巧ackberry app?

I heard that in order to do so I need to purchase a Blackberry Enterprise Server which costs me 1400 per year. Is this true? Where is a good starting point in implementing push notifications?

I am experienced with iPhone push development, but cannot find the equivalent for blackberries.

Earlier this year Blackberry launched a push service that does not require a BES, similar to Apple's offering. The have a Java SDK for it. You can find more information here: http://na.blackberry.com/eng/developers/javaappdev/pushapi.jsp#tab_tab_overview

Well, its true that you need a BES for Blackberry push services.

AFAIK,In a "non BES environment", you can use a number of other methods such as email, SMS or polling to do the 'push'.
