There are two pieces of news for everyone interested in running Java MIDlets. The first will be having a pre-WM5 device and wanting to run Java MIDlets (for example, Opera Mini) on it. Yes, at last, some Russian hackers made Jbed, the industry-leading MIDlet manager work under WM2003(SE)! The second (and, for most people, not that important) piece of news concerns a brand new MIDlet manager port for Windows Mobile.

1. Some Russian hackers, including the 4pda.ru folks, have, at last, managed to make Jbed, the best MIDlet manager, work under WM2003 and WM2003SE. The importance of this just can’t be stressed enough: so far, you only had the really inferior IBM J9 and the 10-series TAO MIDlet Manager to run MIDlets on pre-WM5 operating systems. Now, this has dramatically changed. Now, nothing will stop you from using Opera Mini on your pre-WM5 Pocket PC.

The direct link to these WM2003(SE) MIDlet Managers are as follows. There are three versions: a modded one, a non-3D one and a 3D one; all with a heap size fix.

JBed3dMod_HeapSizeFix
Esmertec Jbed heapfix
Esmertec Jbed3d heapfix

They have also made a MAJOR update to their 4PDA.ru MIDlet article, linking to all the contemporary Esmertec, TAO etc. versions (including ones with heap fixes, with and without 3D support etc.); the above links can also be found in their article. You can see the translation of the new page HERE (Google) and HERE (Babelfish). Note that I’ve kept the original page HERE (Google) and HERE (Babelfish) for historical reasons for people interested in the pre-Esmertec times.

2. Now, the other piece of news, which, again, won’t be of that much interest to non-WM2003 / non-Java hackers.

Java is a really viable programming platform. Not only several high-quality games make it worthwhile, but also probably the best and, if you’re lucky enough with your geographical location, fastest and most bandwidth usage-friendly mobile browser available for mobile phones (including Windows Mobile), Opera Mini 4.

I’ve already devoted an entire all-in-one Bible to running Java on Windows Mobile (and Symbian). Now, let me introduce the latest Windows Mobile KVM: PhoneME.

PhoneME is another "let’s bring Java to various platforms” projects (official homepage HERE), which has recently received Windows Mobile support.

1. After publishing my review of VirtualCE 4, there have been some changes:

1. a new MyMobiler version has been released, implementing, for example, manual screen rotation and the ability to hide the Today screen icon
2. some of the bugs of VirtualCE 4 have been fixed (for example, BMP24 crashing). Hope the developer also finds a way to completely (even from the bottom taskbar) hide the main selector / controller screen as is asked in the above-linked HowardForums thread
3. Pocket Controller 6 has turned out to support LAN discovery and hiding the connection “bubble” upon TCP/IP connection (as opposed to the ActiveSync one).

2. I, after more than a week’s waiting (see my previous post HERE), still haven’t received any feedback from the Strategy Analytics Inc. folks regarding the lack of Opera Mini in their 5-Star Safari Leads Mobile Browsing Experience, which, in many Windows Mobile users’ (including me) opinion, is the most useful / quickest Web browser for the Windows Mobile platform. And, for other mobile platforms too – on my Symbian Nokia N95 and BlackBerry 8800, I almost exclusively use this browser to access the Web. Not including it in the test makes the entire report pretty hard to depend on – it’s like completely ignoring, for example, Ferrari (a top-performing car) when evaluating the cars of Formula-1.

And, of course, I’ve already elaborated on the bad ranking of Nokia Web (running on Symbian S60 3rd edition devices – that is, NOT on Windows Mobile) and, particularly, Opera Mobile (running on all major mobile platforms). Again and again, if you do learn the dialpad shortcuts and/or, with Opera Mobile running on a dialpad-less Pocket PC, use a third-party tool to assign its key functionalities (accessing favorites, current tabs, back etc.) to Pocket PC hardware buttons, they both become quicker and easier to operate than Internet Explorer. It’s clearly at this point (in addition to the lack of Opera Mini) that Strategy Analytics Inc.’s report severely lacks – it’s evident the test folks didn’t really make an attempt at learning the dialpad shortcuts / configure Opera Mobile for easy and much quicker access / use.

(Note that this Bible does NOT discuss Java applets or applications. For more info on running applets under Windows Mobile, see the Web Browsing Bible; for application-related info, see my generic Java articles.)

You may have already heard at least of Java games (more precisely, MIDlets) running on almost all current “dumb” phones. These games are all the rage today, especially with teenagers, which also means there are thousands of sometimes really high-quality games for ordinary phones, all written using the portable Java language, ready to be played on (almost) any kind of mobile phone. Just an example: in THIS HowardForums thread, the topic starter post lists some (but not all!) games available for the Samsung QVGA 240x320 phones (d600, d900, e900 etc – not only Windows Mobile ones!). Quite an impressive list, isn’t it? And it’s just the tip of the iceberg – there are a lot more games, all waiting for you to purchase, download and run!

No, don’t think MIDlets are only for gamers and are absolutely useless otherwise. You can make a good use of them in the enterprise too. There are several solutions already for, for example, mobile payment, reservations etc. done using a MIDlet as opposed to the Web, which is, in a lot of cases, is much harder to access / operate on a small-screen device. Controlling for example your bank transfers via SMS can also be less intuitive and/or require a lot more work / data entry than using a GUI to do this. Other, known enterprise-related MIDlets are Jupiter, which is basically a financial data streaming program (also see THIS) and Betfair (also see THIS). Should you be interested in these “MIDlets in the Enterprise” questions, I really recommend Michael Juntao Yuan’s excellent book “Enterprise J2ME: Developing Mobile Java Applications” – I’ve learnt a LOT from it. Highly recommended!

Lately, with the advent of Opera Mini and the really excellent and highly recommended Gmail MIDlet and some quality games (see their list in the 10/19/2007 update of my 3D MIDlet article), there has been a tremendous increase in the demand for MIDlet-related information. This is certainly shown by the sheer number of MIDlet-related questions asked at XDA-Developers, probably the best, most lively Windows Mobile hardcore user community with the most posts. For example, today, I’ve answered at least 20 different MIDlet-related questions there. Quite a few, isn’t it?

Let me give you all another modest present: in addition to my already-published previews (for example, the 3D Gaming Bible, the 4pda.ru Download Bible etc.), another excerpt – a full chapter – from the forthcoming Bible. Yes, it’s coming and yes, I do try to get it ready tomorrow or the day after – everything, all accompanying screenshots and charts (the main chart; 3D games Compatibility Chart and JBenchmark Chart) are ready, I only need to consolidate all my thoughts into an all-in-one, still-somewhat-comprehensive Bible, which will, I promise, be MUCH better, will contain MUCH more information and MUCH more up-to-date than that of the Russian-only 4pda.ru. Now, look at the length of the 4Pda tutorial (and all the linked-in ones) to see how much information it contains Not very easy to come up with something that has even more info, is it?

Note that the MIDlet managers I refer to in the article can all be found in the main chart of the Bible.
