HTML Java applet如何找到其.jar？

Question

I have this code: 我有以下代码：

document.write("<APPLET CODE='com/synergex/My.class' ARCHIVE='toc2.jar' ");

When my "toc2.jar" is in the same folder as the HTML - all works fine. 当我的“ toc2.jar”与HTML位于同一文件夹中时-一切正常。

But when I put "toc2.jar" in another folder ("C:\\MyJars"), I get ClassNotFoundException . 但是，当我将“ toc2.jar”放在另一个文件夹（“ C：\\ MyJars”）中时，出现ClassNotFoundException 。

How can I "tell" the browser where to look for jars? 我如何“告诉”浏览器在哪里寻找罐子？

I tried to add "C:\\MyJars" or "C:\\MyJars\\toc2.jar" to my CLASSPATH env variable, but it did not work. 我试图将“ C：\\ MyJars”或“ C：\\ MyJars \\ toc2.jar”添加到我的CLASSPATH env变量中，但是没有用。

You might be able to redirect the code base using an HTML base element . 您可能可以使用HTML base元素重定向代码库。

For example, given the following BASE declaration and A declaration: 例如，给定以下BASE声明和A声明：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
   "http://www.w3.org/TR/html4/strict.dtd">
<HTML>
 <HEAD>
   <TITLE>Our Products</TITLE>
   <BASE href="http://www.aviary.com/products/intro.html">
 </HEAD>

 <BODY>
   <P>Have you seen our <A href="../cages/birds.gif">Bird Cages</A>?
 </BODY>
</HTML>

the relative URI "../cages/birds.gif" would resolve to: 相对URI "../cages/birds.gif"将解析为：

http://www.aviary.com/cages/birds.gif

If not, there are only 2 options. 如果没有，则只有2个选项。

Leave the Jar in the same directory as the HTML. 将Jar与HTML放在同一目录中。
Presuming that part of the script is the only thing you cannot change, add codebase='../path/' immediately after it, to tell the JRE to wherever the Jar is located. 假定脚本的唯一部分是您不能更改的，请在该脚本后立即添加codebase='../path/' ，以告知JRE Jar所在的位置。

As an aside: 作为旁白：

CODE='com/synergex/My.class'

Should be: 应该：

CODE='com.synergex.My'
