问题描述

我下载了 适用于Ubuntu Linux的Oracle Java ME SDK 8.3 .

要创建Java Midlet，我需要应该在lib目录中的midp api.目前，我在lib目录中只有这些文件

To create Java midlets I need the midp api which was supposed to be in lib directory. Currently I am having just these files in lib directory

Oracle是否停止了对J2ME移动设备的支持?

推荐答案

虽然没有太多研究，但我敢肯定您只需要SDK 3.4 问题在于JavaME不仅仅是一件事.大多数人在听到JavaME时都会想到手机"(MIDlets)，但实际上还有很多其他事情，例如Blu-ray Disc Java(BD-J Xlets)或用于办公硬件的应用程序(例如打印机)(也包括Xlets)，还是另外一个API).

Haven't looked into it too much, but I'm fairly sure you just need SDK 3.4 The problem is that JavaME isn't just one thing. Most people think "cellphones" (MIDlets) when they hear JavaME, but it's actually a lot of other things too, like for example Blu-ray Disc Java (BD-J Xlets) or apps for office hardware like printers (also Xlets, but yet again a different API).

在我看来，SDK 8>仅专注于Xlet开发，而SDK< 8则专注于MIDlet.当没有新的MIDP API时，就没有必要为MIDlet开发新的SDK.

Seems to me that SDK 8> just focuses on Xlet development, while SDK <8 focuses on MIDlets. No point in making new SDK's for MIDlet development when there are no new MIDP API's.
