I am running my app on google app engine. All I have is a simple servlet that is trying to use Jsoup. However when I run the application I get java.lang.ClassNotFoundException: org.jsoup.Jsoup.

我正在使用Eclipse，所以我在Java Build Path-> Libraries中添加了jsoup jar文件

推荐答案

您需要将Jsoup JAR文件放入Webapp的/WEB-INF/lib文件夹中.该文件夹包含在webapp的默认类路径中.而且，Eclipse会自动将所有库放在项目的构建路径中的/WEB-INF/lib文件夹中，您不需要手动执行此操作.当然，我假设该项目是作为动态Web项目创建的.

You need to put the Jsoup JAR file in the /WEB-INF/lib folder of the webapp. That folder is covered by webapp's default classpath. Also, Eclipse will automagically put all libraries in /WEB-INF/lib folder in the buildpath of the project, you shouldn't need to do that manually. Of course I assume that the project is been created as Dynamic Web Project.
