java-me - 从 midlet 启动另一个 midlet

Question

我制作了程序 Test.jar，其中有一个菜单可以运行另一个程序 (Hello.jar)。我一直在寻找并得到以下代码

callLauncher("javaapp:midlet-name=Hello;midlet-vendor=Vendor");

和

PushRegistry.registerAlarm("Hello",now.getTime()+100);

但不成功 - 抛出 ClassNotFoundException。还有别的办法吗？

Answer 1

API documentation for the method you use (registerAlarm)非常清楚地解释了你做错了什么:

Throws:
...ClassNotFoundException - if the MIDlet class name can not be found in the current MIDlet suite or if this class is not included in any of the MIDlet-<n> records in the descriptor file or the jar file manifest or if the midlet argument is null
