  • Universidade de Vigo
  • Overzicht
  • Gebruikte technologieën
    • Wireless devices
    • HTTP connection
    • Database Server
    • Wireless devices
    • HTTP connection
    • Database Server
    Gebruikte technologieën
  • Wireless devices
    • extremely limited memory
    • Small screen sizes
    • Alternative input methods
    • Slow processors
  • Java technology
    • Enterprise Edition (J2EE)
    •  Servers
    • Standard Edition (J2SE)
    •  Desktops
    • Micro Edition (J2ME)
    •  Small devices
  • J2ME
    • Configurations
    •  Hardware capabilities of mobile devices
    • Profiles
    •  Define the full set of API classes
  • J2ME - Configurations
    • Connected Device Configuration (CDC)
        • 2MB of memory
        • 32-bit microprocessor or controlller
        • an available network connection, preferably high bandwidth
    • Connected Limited Device Configuration (CLDC)
          • Minimum of 160KB total memory
          • Minimum 16-bit 25 MHz-processor
          • Limited user-interface facilities
          • No (or intermittent) low-bandwidth network connection
  • J2ME – Profiles (CLDC)
    • Mobile Information Device Profile (MIDP)
    •  today’s mobile devices
    •  limited subset of J2SE’s feature set
    •  custom interface and input/output classes
    • Personal Digital Assistant Profile (PDAP)
    •  a superset of the MIDP
    •  PIM,…
  • J2ME – MIDP
  • Programs used
    • JCreator
    • Wireless Toolkit 2.0
  • Gebruikte technologieën
    • Wireless devices
    • HTTP connection
    • Database Server
  • HTTP
    • Just an interface on the client
    •  a kind of ‘browser’
    • Data is on the server
    •  Connection is needed
  • HTTP
    • HyperText Transfer Protocol
    • HTTP transaction
      •  request send by the client to the server
      •  response returned from the server to the client
  • XML
    • eXtensible Markup Language is a meta-language that describes the content of the document (self describing data)
    • XML does not specify the tag set or grammar of the language
    • XML is a cross-platform ,software and hardware independent tool for transmitting information
  • XML
  • XML Parsing
    • Reading the data out of the tags
    • kXML
  • Gebruikte technologieën
    • Wireless devices
    • HTTP connection
    • Database Server
  • Database Server
    • Information was stored in a SQL database
        • SQL= Structured Query Language
    • ASP (Active Server Pages)
          • Used to generate the XML files
          • aspx – VB.NET
  • Final overview
  • Developed Project
  • Conclusions
    • J2ME will be the dominant platform for mobile devices
        •  450 million handsets (2007)
    • Data processing on the server side
    • Limitations of the devices
