xpages:java.lang.ClassNotFoundException:在 NSF 中找不到类 org.apache.commons.httpclient.HttpMethod [英] xpages: java.lang.ClassNotFoundException: Cannot find class org.apache.commons.httpclient.HttpMethod in NSF

问题描述

我编写了一个使用 org.apache.commons.httpclient 的 java 类.

I have written a java class that utilises org.apache.commons.httpclient.

最初我将 java 文件连同编解码器依赖项一起导入到我的 nsf 中；该应用程序运行良好.然后我发现这些在 eclipse plugins 目录中可用；所以我然后将它们添加为 plugin.xml 中的依赖项

Initially i imported the java files into my nsf along with codec dependencies; the application worked fine. I then found that these were available in the eclipse plugins directory; so i then added them as a dependency in the plugin.xml

现在，当我尝试运行该应用程序时，出现错误 500，并且 xpages_exc 技术支持文件中记录了以下内容:

Now when i try to run the application i get an error 500 and the following is recorded in the xpages_exc tech support file:

推荐答案

在 WebContent\WEB-INF 下创建一个名为 lib 的文件夹.您不需要将其添加到构建路径中.将 apache commons jar 作为 jar 导入其中.然后它对我有用，但正如我所说，我没有在一台服务器上测试过一种以上的方法.

Create a folder under WebContent\WEB-INF called lib. You don’t need to add it into the Build Path. Import the apache commons jar into that as a jar. Then it worked for me, but as I say I haven’t tested on more than one method on one server.

在这个问题中也有导入插件到 XPage 项目不工作
