An apparatus and method of establishing communication between a first application
added to a platform, and a second application executing on the platform, controls
the first and second applications to establish a path for interapplication communication.
To that end, a notify message is forwarded to the second application when the first
application is added to the system. Receipt of the notify message by the second
application causes the second application to ascertain path data for establishing
a path between the two applications. The first application also ascertains path
data for establishing a path between the applications. The first and second applications
then are controlled to establish a single path between the first application and
the second application after the path data is ascertained.
