Up until this point, the utilization of cell phones in the introduction of climate estimates was restricted and noninteractive. This application gives an intelligent access to meteorological items in Croatia. It has been created in the MicroJava programming language and effectively tried in an emulator and on genuine cell phones. The quick improvement of portable advancements will take into consideration concentrated utilization of such items. Watchwords: Java, climate figure, MIDlet, J2ME, MicroJava, cell phone, remote, GPRS 1.Introduction This paper portrays another strategy for climate estimate introduction dependent on current versatile correspondence innovations †right now the quickest developing industry on the planet. Late investigations show that each fifth individual on the planet claims a cell phone, and in Croatia in excess of 80 percent of family units have at any rate one; simultaneously, just 37 percent have a PC (GFK, 2003). 2. Innovation In June 1999, Sun Microsystems declared another version of the Java 2 stage: the Java 2 Micro Edition - J2ME (Muchow, 2002).The motivation behind the Micro Edition is to empower Java applications to run on figuring gadgets with restricted PC force, memory and show, for example, cell phones, PDAs, pagers, and so forth. It depends on the famous Java programming language, and the application is called MIDlet. MIDlet is a contraction made out of two words: MID for Mobile Information Device, and â€Å"let† is the postfix of â€Å"applet†, which implies portable application (Piroumann, 2002). After some time, this innovation has gotten standard with the new age cell phones, so practically all new models bolster it, freely of who produces them.Thanks to the Java innovation, cell phone highlights can be improved through intelligent, powerful applications which can be downloaded and put away in a cell phone. What's more, when a client needn't bother with them any more, they can be handily deleted. Instances of various Java applications incorporate intuitive games, utilities, association and travel programs, and so on 3. Application in climate figure In Croatia, just as abroad, current innovations (radio, TV, paper) have been abusing climate estimate introductions for quite a while as of now so that there are restricted prospects left of further turn of events (particular TV-stations and so on. In the most recent decade, the quick improvement of portable innovation has presented an essentially better approach for correspondence and living. Up until this point, the climate figure in cell phones was for the most part introduced through SMS (short message administration) and MMS (mixed media message administration), WAP pages and so forth. The hindrance of such a methodology is, that the client consistently gets a similar item. The Java innovation, then again, permits the structure of programming that gives intelligent access through the instinctive interface, at any ideal time and in each place.Besides climate conjectures, clients can likewise recover constant data, for example, information from programmed synop stations, radar and satellite pictures (each 15 and 30 minutes, individually), exceptional alerts, nowcastings and so forth. As the application utilizes information from the Internet, autonomously of the portable supplier, clients can get to the ideal data regardless of where they are, whether in Croatia or abroad. 4. Introduction A MIDlet, named CroWeather, with a total climate estimate, has been made as a University project.Forecasts are given for the present and the next day, literarily and in picture group. With respect to real information, other than satellite and radar pictures, this MIDlet likewise gives literary information on current climate conditions as temperature, pressure, mugginess a nd so forth. Clients can pick among various Croatian urban communities and the principle areas. The program is a purported MIDlet application. It ought to be introduced on Javaenabled cell phones, and is written in the MicroJava programming language. The server side contents giving records and information are composed mostly in PHP and Fortran 90, for the most part in a Unix environment.The application was created utilizing Sun’s Wireless Toolkit (- , Java 2 Micro Edition, 2000) that imitates Java-empowered cell phones, and was effectively tried on a few cell phones (Nokia 7650, Nokia 3650) In 2001, cell phones of the 2,5 age were simply being acquainted with the Croatian market. From the start, it was hard to locate a cell phone that would consent to the highlights required (Java-empowered, GPRS, shading show alluring), so that at the time just one sort really coordinated our criteria.Although the application worked effectively on the emulator, we encountered a few troubles when testing i t on a genuine gadget. Lacking usage of Java in the real gadget (during http demands the application would stop and would not work in a solitary string, so we utilized multithreading), and the versatile supplier didn't bolster the exchange of information records bigger than 5 kB. As each other, this Java MIDLet additionally comprises of two records. One with a . container augmentation (Java document), which is the real MIDlet, and another with a . promotion expansion (Java application portrayal), a plain book document that contains some broad information about the application, adaptation, writers, maker and so forth. The absolute size of the records is cca 30 kB, so they can be effortlessly downloaded to a cell phone through an IR (infrared) or Bluetooth association, or in any case legitimately from the WAP pages (OTA †over the air). When the documents are downloaded, clients can just introduce the MIDlet through the Java application chief, contingent upon the cell phone type (Topley, 2002). The accompanying introduction comprises of screen captures taken on the Nokia 7650 cell phone. Highlights: Figure 1. Printed data about momentum climate conditions in 32 Croatian mainland and seaside urban communities (climate depiction, temperature, dampness, pressure, time change of weight, wind, ocean temperature, snow tallness †all refreshed hourly) Figure 2.

Other than general data about the application, creators and so forth, clients can check if there is another rendition of the program and download it 5. End CroWeather for Java-empowered cell phones has been effectively tried on a few kinds of gadgets. The application is little and isn't PC costly, which makes establishment and use generally simple. Present day remote innovation joined with Java innovation gives propelled use of items, for example, climate gauges, so the client can specifically and intuitively get to the ideal information, regardless of where he is. The creators accept that this and comparable arrangements, and their applications, will assume a prevailing job in current climate estimate introduction, particularly with respect to the newcoming ages of versatile devices.References - , Java 2 Micro Edition, Wireless Toolkit User’ Guide, Release 1. 0.
