Applet 在 weblogic 11 中找不到类

发布于 2024-11-06 01:01:57 字数 1036 浏览 3 评论 0原文

我有一个小程序和一些 jar 文件中的库。显然，当我将所有必需的类添加到 IDE (JDeveloper) 中的库路径时，所有必需的类都通过我的小程序进行了部署。但它无法访问这些类。小程序只是冻结了，没有任何错误。也许是安全权限造成的？这是部署存档中的结构（war）

WEB-INF
    classes
      my
      other_packages
    lib
      jar libs are here
applet.html
my
  package of classes, don't know why it is duplicated

这是 HTML 文件：

<APPLET CODE="my.base.Applet1"  
 HEIGHT="200" WIDTH="200" MAYSCRIPT ALIGN="bottom">This browser does not support Applets.
</APPLET>

我尝试添加 jar 库，并且仅当我使用小程序从本地磁盘打开 html 文件时它才有效。我必须将库的路径指定为 ARCHIVE="WEB-INF/lib/commons-logging.jar"。如果我只使用官方教程中的“commons-logging.jar”，则会导致“找不到类”错误。因此，当部署在服务器上并通过 http 访问时，即使使用 ARCHIVE="WEB-INF/lib/commons-logging.jar" 也找不到这些 jar 文件。

我使用 JDeveloper 并将 html、applet 和库作为 war 文件部署到 Weblogic 11。

我还尝试了 CODEBASE 属性，其中 CODEBASE="/bea_wls_internal/classes/" 以及指定的附加“appName@componentName” 代码库 =“/bea_wls_internal/classes/appName@componentName”。也许我错误地使用了“appName@componentName”，但只有几个不清楚的示例如何使用它。

任何帮助将不胜感激。

原文

I have an applet and a few libraries in jar files. Obviously, all required classes are deployed with my applet as I added them to library path in my IDE (JDeveloper). But it can't access these classes. The applet just freeze ups without any errors. Maybe it caused by security permissions ? Here is a structure in deployment archive (war)

WEB-INF
    classes
      my
      other_packages
    lib
      jar libs are here
applet.html
my
  package of classes, don't know why it is duplicated

Here is HTML file:

<APPLET CODE="my.base.Applet1"  
 HEIGHT="200" WIDTH="200" MAYSCRIPT ALIGN="bottom">This browser does not support Applets.
</APPLET>

I tried to add jar libraries and it works only if I open html file with applet from local disk. I have to specify path to libraries as ARCHIVE="WEB-INF/lib/commons-logging.jar". If I use just "commons-logging.jar" as it was in official tutorials it causes "Class not found" error.
So it can't find these jar files even with ARCHIVE="WEB-INF/lib/commons-logging.jar" when deployed on server and accessed through http.

I use JDeveloper and deploy html, applet and libraries as a war file to Weblogic 11.

I also tried CODEBASE attribute both with CODEBASE="/bea_wls_internal/classes/" and with additional "appName@componentName" specified
CODEBASE="/bea_wls_internal/classes/appName@componentName". Maybe I use "appName@componentName" wrong but there are only few not clear examples how to use it.

Any help will be appreciated.
