Question

我可以在包中使用小程序吗？即：

bfwd.RedemptionOnline.client

将是包，RedemptionOnlineApplet.class将存在于该包中。如果可以的话，如果它存在于RedemptionOnline.jar中，你将如何为它创建标记？

这是我正在使用的标签：

<applet code="bfwd/RedemptionOnline/client/RedemptionOnlineApplet" width="1" height="1" archive="RedemptionOnline.jar">
    <PARAM NAME="MAYSCRIPT" VALUE="true">
</applet>

这是我得到的错误的日志：

Answer 1

是的，小程序可以在软件包中 - 虽然我建议您遵循约定并将软件包命名为

com.bfwd.redemptiononline.client

创建标记时，您只需指定完全限定名称：

com.bfwd.redemptiononline.client.RedemptionOnlineApplet.class

或者可能（文档各不相同，自从我完成任何applet工作以来已经很长时间了）

com.bfwd.redemptiononline.client.RedemptionOnlineApplet

甚至：

com/bfwd/redemptiononline/client/RedemptionOnlineApplet.class

Answer 2

如果您的Applet类打包在可由http://example.com/RedemptionOnline.jar下载的JAR文件中，那么您应该在code中指定打包类的完全限定名称，并在（{relative}）中指定（相对）公共Web URL。 archive中的JAR文件（注意：区分大小写！）：

<applet code="bfwd.RedemptionOnline.client.RedemptionOnlineApplet" archive="RedemptionOnline.jar">

（我同意Jon的说法，包名应该是小写的，符合Java Naming Conventions）

如果您的Applet类只是公共Web内容中的.class文件，可由http://example.com/bfwd/RedemptionOnline/client/RedemptionOnlineApplet.class下载，那么您应该在code中准确指定其（相对）公共网址（注意：也区分大小写！）：

<applet code="bfwd/RedemptionOnline/client/RedemptionOnlineApplet.class">

您现在是否了解何时使用句点以及何时使用斜杠以及何时使用后缀.class？
