Building smart J2ME mobile applications, Part 2
This
tutorial shows you how to synchronize order information stored in the
J2ME Record Management System with a remote, open source Cloudscape
database. You'll build your own two-way synchronization logic. The
mobile application supplies all the information necessary for a remote
sever-based application to act upon, ship the ordered product, and
update the product information in a remote Cloudscape database. The
mobile user can track the status of the order by synchronizing with
this database. |

Navigate the file system on a mobile device
The
Java 2 Platform, Micro Edition (J2ME) Mobile Device Information Profile
(MIDP) does not provide out-of-the-box support for accessing a file
system. The optional package that provides this capability is defined
by Java Specification Request (JSR) 75. Two packages are included in
JSR 75: the Personal Information Management (PIM) package and the
FileConnection package. This tutorial focuses on the FileConnection
package, with an emphasis on learning how to navigate a directory tree
and access files. The tutorial takes you through the steps to build a
simple file and directory explorer application. It includes moving
through a directory hierarchy, viewing file permissions, and opening
and reading a file's contents. |

Build smart J2ME mobile applications, Part 1
This
tutorial is the first in a two-part series designed as a step-by-step
guide to building a smart Java 2 Platform, Micro Edition (J2ME) mobile
application. In this tutorial you learn how to build a simple mobile
application for order placement. The example application uses the J2ME
record management system (J2ME RMS) to store order information and a
MIDlet to perform the necessary logic of creating and accessing the
database application. You learn how to work with the J2ME RMS, craft a
MIDlet, and deploy the resulting application to a J2ME environment. |

Use Eclipse to develop mobile applications for Nokia devices
This
tutorial demonstrates how to develop Java 2 Platform, Micro Edition
(J2ME) applications for Nokia handsets using the Eclipse IDE and the
Nokia Developer's Suite for J2ME. It is written for J2ME and Nokia
developers who are interested in using the powerful Eclipse IDE to
boost productivity. It also targets existing Java Eclipse developers
who need a short path to get started in real-world mobile application
development for Nokia devices. Although the Nokia Developer's Suite for
J2ME primarily provides tools for Nokia handset developers, you can use
it for generic J2ME application development for other devices as well. |

Threads and networking in J2ME
This
tutorial teaches you how to use threads in MIDlets to communicate over
a network connection. Without multithreading, a MIDlet that requests a
network connection blocks while waiting for a response from the
network. In the real world, a user expects the application to continue
running, even while a network connection is underway. The tutorial
demonstrates the problems of non-threaded MIDlets and lets you build a
multithreaded MIDlet. |
| |
Mobile database access
This
tutorial shows you how to build a database application using Java 2
Micro Edition (J2ME) Record Management System (RMS). It also

Develop Web services clients for mobile devices
This
tutorial guides you through the necessary steps to build mobile Web
services clients on J2ME MIDP devices. By following the steps in this
tutorial, you will see how quick and easy it is to create a Web
services client. The example built in this tutorial is a stock quote
client application. Using the WebSphere Studio Device Developer V5.6
Web Services tooling, you can generate a client stub and a MIDlet that
will take a stock symbol as input and retrieve the most current price
(time delayed, of course). Finally, it guides you through the steps
necessary to run the MIDlet on the Device Developer MIDP emulator. |
