There are so many app stores for any kind of platform out there, but when I try to find a good store to buy and sell j2me apps, I find some, but no really big one or defacto standard like I was used to have for the palm os (sites like palmgear sell nearly every program ever made for the palm and not only a subset).
Is there a store which I havn't found yet? Or is the j2me market dead?
There is no standard app store for j2me apps, and nither didexist for any other platform until Apple had invented the iPhone one. Since the Apple app sotre, almost all vendors created one, such as OVI for Nokia, AppWorld for BlackBrry and the Windows Mobile Marketplace. Also Sun came up with the Java Store, but it aimed only at desktop apps at the moment.
Since there was a clear void, many companies have created stores for mobile apps, most of theme support non-j2me apps (Windows Mobile, Symbian, etc.). The two largest ones are Handango and GetJar. Of the new stores, OVI and AppWorld sell j2me apps. Other stores such as PocketGear and MobiHand sell BlackBerry apps as well, but not pure j2me ones.
Given that, it seems that most the applications in the j2me are sold via the operators' portals or stores (like AT&T Media Mall) or pre-installed on the devices themselves. The outcome of this is that it relatively hard to sell j2me app, comparing to the smartphone arena (iPhone, Android, Blackberry, etc.)
GetJar is pretty much the only cross-platforms J2ME appstore I would be comfortable in relying on as a developer.
Then, I would directly go to Mobile Network Operators and Handset Manufacturers appstores.
Nokia's Ovi store? Seems like the only one that's really actively promoted and fairly large.
How about Handango?
Please look at Handango web page for Java ME IM+ for Skype app as sample.
Here is one link that seems to have good collection of Mobile Apps for J2ME devices not mentioned in any of the previous posts.
