不需要使用部署一个applet数码code签约插件2（PI2 - 1.6.0_10 +）架构JRE。在PI2 JRE，嵌入式小程序可以访问所有的服务通常只提供给Java Web Start的应用程序。

Digital code signing is not required for an applet deployed using a Plug-In 2 (PI2 - 1.6.0_10+) architecture JRE. In a PI2 JRE, an embedded applet can access all the services normally only available to Java Web Start apps.

感兴趣此applet的服务将是 FileOpenService （ FOS）和 PersistenceService （PS）。果寡糖可以用于允许用户导航到一个文件（或更确切地说 - 一个FileContents）从它的对象，将获得的流。一旦用户满意裁切的图像，在保存到PS为以后的检索（使用ImageIO的，前面已经提到）。

The services of interest to this applet would be the FileOpenService (FOS), and the PersistenceService (PS). The FOS could be used to allow the user to navigate to a File (or rather - a FileContents) object and obtain streams from it. Once the user is happy with the cropped image, save in to the PS for later retrieval (using ImageIO, as already mentioned).
