15: Creating push applications
Code sample: Pushing data to an application that listens on a
BlackBerry device
The HTTPPush.java sample application, which uses standard Java™, sends a string of text to a listening client
application on the BlackBerry® device using either a RIM push or a PAP push. The application pushes data based
on an
email address. To test push applications with the BlackBerry device simulator, define a mapping between
the
email address and the BlackBerry device simulator PIN (2100000A).
The following code sample compiles using J2SE 1.4.2.
Example: HTTPPushServer.java

/**
* <p>The HTTPPushServer class provides a simple PUSH server sample.
* <p>This program will send text to a listening device. The associated client demo
* is HTTPPushServer. Start up both the device simulator and MDS before executing
* this program. For reliable push, append the port that you are pushing to in
* rimpublic.property file (push.application.reliable.ports):
* <code>push.application.reliable.ports=7874,<b>100</b></code
*
* <p> The general form of the URL for posting (pushing) data to the device is:
* http://&lt;host&gt;:&lt;port&gt;/push?DESTINATION=&lt;device
pin&gt;&amp;PORT=&lt;device_port&gt;&REQUESTURI=&lt;post uri&gt;
