This paper describes research in the use of the Security and Trust Services API for J2ME (SATSA) to develop mobile applications. for 3G networks. SATSA defines a set of APIs that allows J2ME applications to communicate with and access functionality, secure storage and cryptographic operations provided by security elements such as smart cards and Wireless Identification Modules (WIM). A Java Card application could also work as an authentication module in a J2ME-based e-bank application. The e-bank application would allow its users to access their bank accounts using their cell phones.

This paper describes research in the use of the Java Real-Time System to develop a Real-time applications. This page that can help you troubleshoot and resolve problems that might occur in applications that are developed with Sun Java™ Real-Time System (Java RTS). The guide concentrates on issues that are specific to the Java RTS VM. For problems with applications that are developed on the Java SE 5.0 platform, with the Java HotSpot™ VM.

This paper describes research in the use of the PC/SC to develop Smart Card applications. This page was designed to give you a basic understanding of how to setup PC/SC communication with a reader and card. This is a great starting point, however it leaves out the most important part, card communication. We have left this out purposfully because every card communicates differently. allowing you to get a basic understanding of how easy it can be to access smart cards from any PC/SC compliant reader.

The Business intelligence(BI)is to appear on various mature technology bases such as computer soft hardware,network,communication,decision-making,is one item technology used for handling magnanimous data.It requires to discovering thelaw from the various data resource(Data base,Data Warehouse,Web etc. ),and this will be mainly dependent on the data storehouse(DW),On-Line AnalyticalProcessing(OLAP),datamining(DM). This paper presents the working state of the BI system in a retail enterprise, and elaborates the realization of a BI system and the effect of the practical application under the data environment of a complex business system. This paper also introduces the whole process of the BI project , including the proof of the BI system, the plan shaping, the design of data warehouses, the data mining and the frontier data presentation.

This paper describes research in the use of the Java Bluetooth to develop a Wireless applications. Bluetooth is a short-range universal wireless connectivity standard for electronic appliances and mobile devices. This page that can give you an overview of the typical elements of a Bluetooth-enabled MIDlet application, and introduce you to the core Java Bluetooth APIs. Finally we'll look at some code that shows how to use these APIs.

This paper describes research in the use of The Java Server Faces (JSF) to develop web applications for CRM. JSF is a standardized specification for building User Interfaces (UI) for server-side applications. If you are familiar with Struts (a popular open source JSP-based Web application framework) and Swing (the standard Java user interface framework for desktop applications), think of Java Server Faces as a combination of those two frameworks. Like Struts, JSF provides Web application lifecycle management through a controller servlet; and like Swing, JSF provides a rich component model complete with event handling and component rendering.

This paper describes research in the use of The Java 2 Platform, Micro Edition (J2ME) to develop mobile applications. for 3G networks. This paper introduces the structure of our J2ME computer vision library and describes the implementation of algorithms in our library. A type of J2ME-based mobile e-commerce system design program is presented, the program has the advantages such as simple realization, strong maneuverability. The J2ME Wireless Toolkit provides a compiling and testing environment for developing applications for CLDC/MIDP compliant mobile phones.

This paper describes research in the use of the RMI to develop Java Card applications. the Java Card RMI (JCRMI), which is based on the J2SE RMI distributed-object model. In the RMI model a server application creates and makes accessible remote objects, and a client application obtains remote references to the server's remote objects, and then invokes remote methods on them. In JCRMI, the Java Card applet is the server, and the host application is the client.
