Opera Mini for Java is a more compact version of the independent Opera web browser experience. The software is written in Java language which is platform agnostic with a Java runtime package available for numerous computing platforms. However, primarily Opera Mini is used on various mobile computing platforms that have limited memory or processor capacity and need a web browser that will run on an older mobile platform. This coupled with the fact that some older phones already run a Java-based operating system making them ideal recipients for the Opera Mini for Java software.
The browser also focused on minimal use of screen real estate as many phones using Java have limited size screens. Web pages can be crunched down to load faster and display quicker. Enhanced button navigation to make navigating around web sites on a small screen easier. Share favorite pages easily with friends. Strong security and privacy for data.
Windows Mobile 5 and 6 users can download Opera Mini directly to their phone for free from m.opera.com/next/ or read more at www.opera.com/mini/next/. Java is not required on the mobile phone for this download.

Opera Mini was derived from the Opera web browser for personal computers, which has been publicly available since 1996.[11] Opera Mini was originally intended for use on mobile phones not capable of running a conventional Web browser.[12] It was introduced on 10 August 2005, as a pilot project in cooperation with the Norwegian television station TV 2,[13] and only available to TV 2 customers. The beta version was made available in Sweden, Denmark, Norway, and Finland on 20 October 2005.[14] After the final version was launched in Germany on 10 November 2005,[15] and quietly released to all countries through the Opera Mini website in December, the browser was officially launched worldwide on 24 January 2006.[16]On 3 May 2006, Opera Mini 2.0 was released. It included new features such as the ability to download files, new custom skins, more search engine options on the built-in search bar, a speed dial option, new search engines, and improved navigation.[17]On 1 November 2006, Opera Mini 3 beta introduced secure browsing, RSS feeds, photo uploading and content folding.[18] Content folding works by folding long lists such as navigation bars into a single line that can be expanded as needed. A second beta was released on 22 November,[19] and on 28 November, the final version of Opera Mini 3 was released.[20]
On 7 November 2007, Opera Mini 4 was released. According to Johan Schön, technical lead of Opera Mini development, the entire code had been rewritten.[21] Opera Mini 4 includes the ability to view web pages similarly to a desktop based browser by introducing Overview and Zoom functions, and a landscape view setting. In Overview mode, the user can scroll a zoomed-out version of certain web pages.[22] Using a built-in pointer, the user can zoom into a portion of the page to provide a clearer view; this is similar to the functionality of Opera's Nintendo-based web browsers. This version also includes the ability to synchronise with Opera on a personal computer.[23][24]Prior to Opera Mini 4, the browser was offered in two editions: Opera Mini Advanced for high-memory MIDP 2 phones, and Opera Mini Basic for low-memory MIDP 1 phones.[25] Opera Mini 4 replaced Opera Mini Advanced.[26] Originally, Google was the default search engine on Opera Mini.[27] On 8 January 2007, Opera Software and Yahoo! announced a partnership to make Yahoo! search the default instead.[28] On 27 February 2008, Opera Software announced that Google would henceforth be the default search engine for Opera Mini and Opera Mobile.A version for the Android operating system was announced on 10 April 2008. Rather than port the code to Android, a wrapper was created to translate Java ME API calls to Android API calls.[29]
Most Opera Mini versions use only the server-based compression method, with maximal compression but some issues with interactive web apps. Opera Mini can operate in three compression modes: "mini" (or "extreme" on Android versions), "turbo" (or "high" on Android versions) and uncompressed.[3][38] The turbo and mini modes reduce the amount of data transferred, thereby also increasing speed on slower connections.[3]
The Java ME and Windows Phone versions only have access to the mini compression mode.[3] Other versions can switch between various modes, gaining functionality at the cost of lower or no compression.[42] Opera Software claims that Opera Mini reduced the amount of data transmitted up to 90% in the mini (extreme) mode; in turbo (high) mode, it reduced amount up to 60%, similar to Google Chrome's Reduced Data mode.[38][43][44]
Opera Mini relies on data centers processing the Web page before sending it back to the phone in a compressed binary form. Opera Software operates data centers in the United States, Norway, China, Korea, Poland and Iceland.[66][67]
This extension connects your browser to the JDownloader, which is a Java-based download manager. The extension offers two operation modes:
1. Sends downloading jobs from the right-click context menu
2. Interrupts the built-in download manager and redirects your requests to the JDownloader
The second mode is disabled by default. To enable it, click on the browser action button once. Whenever the interruption mode is not needed, click the browser action button one more time to disable this optional feature.
Since this extension needs to execute native commands to communicate with the JDownloader, a native client is needed. The instruction to install this NodeJS native client is shown on the first use. Also note that this extension only calls the JDownloader, so you need to have this application on your operating system for this extension to work. You can check the code of the native client on -client/releases. There is a short video tutorial about the installation of the native client and its usage:

Myös kehittyneille kämmentietokoneille ja älypuhelimille (Palm OS, Symbian OS, Windows Phone, Windows Mobile) Opera Mini antaa näin mahdollisuuden selata Internetiä pienemmin tiedonsiirtokustannuksin. Ohjelmasta on olemassa kaksi eri versiota (basic & advanced) puhelimen muistimäärän mukaan. Sen voi ladata suoraan puhelimen omalla WAP-selaimella osoitteesta mini.opera.com.
