Five Years On, Has J2ME's Time Finally Arrived?
jg21 writes "Although he admits to having been frustrated by the slow adoption of the J2ME platform, software developer Eric Giguere believes that we're 'turning the corner.' He remembers Sun demonstrating Java running on Palm OS 'way back in 1999 when so many hoped the wireless Java revolution was just around the corner. Five years on, with notable successes such as the J2ME-enabled BlackBerry wireless handheld, that has already made a billionaire of RIM founder Mike Lazaridis, Giguere claims that, with most of the new handsets being produced supporting either JTWI or else its key component - version 2 of the Mobile Information Device Profile (MIDP) - developers finally now have a more consistent and capable platform to use for application development. Anyone wandering round this week's CES may be inclined to agree."
Well I developed and tested J2ME applications on many different mobile phones. Performance optimizations were needed only for Sony Ericsson T series phones. Everywhere else I found the performance of the applications to be acceptable, in most cases you cannot see response time difference between J2ME application and native application of the mobile device. There are few tricks used, in order to be achieved this. (example: on some devices the JVM is loaded not on the start of the application, but when you go to the J2ME applications phone menu). Sorry when my english is bad, I'm not native english speaker.
