未搜索 Applet jar 中的文件
出于示例目的，假设我在网站上有一系列位置，并且 url 的格式为 /location/#/，其中 # 是我要查看的位置的 ID。由于我将 Django 与 Apache 结合使用，因此所有静态内容都位于 /media 中。每个位置页面都尝试加载一个允许文件上传的 Java 小程序。
<applet
codebase="/media/java/"
code="com.elementit.JavaPowUpload.Manager"
archive="JavaPowUpload.jar, commons-logging-1.1.jar, commons-httpclient-3.1-rc1.jar, commons-codec-1.3.jar"
width="200"
height="100"
name="java-uploader"
id="id-java-uploader"
mayscript="true"
alt="JavaPowUpload by www.element-it.com"></applet>
所有列出的 jar 文件都位于 /media/java/ 中，并由 Web 服务器找到。小程序似乎可以毫无问题地加载到页面上，但是当查看页面加载期间的网络流量时，我发现存在几个错误。基本上，小程序似乎正在寻找 jar 内的文件，例如 com.elementit.JavaPowUpload.Messages_en.class，但正在向 Web 服务器请求它们，这相当于请求 /media/java/com/elementit/JavaPowUpload/ Messages_en.class，当然不存在。请注意，如果我摆脱代码库并给出每个 jar 的完整路径，我仍然遇到类似的问题，其中请求是 /location/#/com/elementit/JavaPowUpload/Messages_en.class。如何设置以便搜索 jar 文件而不是文件系统？
For example purposes, let's say I have a series of Locations on a website and the urls are of the form /location/#/ where # is the id of the location I want to view. Since I'm using Django with Apache, all of my static content is in /media. Each Location page is trying to load a Java applet that allows for file uploads.
<applet
codebase="/media/java/"
code="com.elementit.JavaPowUpload.Manager"
archive="JavaPowUpload.jar, commons-logging-1.1.jar, commons-httpclient-3.1-rc1.jar, commons-codec-1.3.jar"
width="200"
height="100"
name="java-uploader"
id="id-java-uploader"
mayscript="true"
alt="JavaPowUpload by www.element-it.com"></applet>
All of the listed jar files are in /media/java/ and are found by the web server. The applet appears to load on the page without a problem but when looking at the network traffic during page load I see there are several errors. Basically the applet seems to be looking for files that are within the jar, say com.elementit.JavaPowUpload.Messages_en.class, but is asking the web server for them, which amounts to requesting /media/java/com/elementit/JavaPowUpload/Messages_en.class, which of course does not exist. Note that if I get rid of codebase and give the full path to each jar, I still have a similar problem where the request is then /location/#/com/elementit/JavaPowUpload/Messages_en.class. How do I set things up so that the jar file is searched rather than the filesystem?

请参阅 codebase_lookup 小程序属性。
See the codebase_lookup applet attribute.
尽管从不同服务器上的另一个页面获取此代码，但小程序的代码属性中似乎存在轻微错误。将 .class 添加到字符串解决了我的问题，但我不确定为什么它在其他主机和页面上没有它的情况下也能工作。
Despite taking this code from another page on a different server, it appears there is a slight error in the applet's code attribute. Adding .class to the string fixed my problem, but I'm unsure why it works without it on the other host and page.
