As you can see from the products mentioned in this article, the J2EE developer interested in developing and deploying mobile applications can utilize products from leading vendors to extend an application to field workers, a global sales force, or even the public at large. Of all the companies developing J2EE application server products, Oracle and IBM have clearly made the largest commitment to mobile applications by seeking to jump-start the development of these apps through a suite of compatible products (client and server software plus middleware), all designed to integrate with their "flagship" application server products.
