Getting a java.lang.ClassNotFoundException: org.jsoup.Jsoup
提问by gk1
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.
我在谷歌应用引擎上运行我的应用程序。我所拥有的只是一个尝试使用 Jsoup 的简单 servlet。但是，当我运行应用程序时，我得到 java.lang.ClassNotFoundException: org.jsoup.Jsoup。
I am using Eclipse so I added the jsoup jar file in the Java Build Path -> Libraries
我正在使用 Eclipse，所以我在 Java Build Path -> Libraries 中添加了 jsoup jar 文件

You need to put the Jsoup JAR file in the /WEB-INF/libfolder of the webapp. That folder is covered by webapp's default classpath. Also, Eclipse will automagically put all libraries in /WEB-INF/libfolder 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.
您需要将 Jsoup JAR 文件放在/WEB-INF/libwebapp的文件夹中。该文件夹由 webapp 的默认类路径覆盖。此外，Eclipse 会自动将所有库放在/WEB-INF/lib项目构建路径中的文件夹中，您不需要手动执行此操作。当然，我假设该项目是作为Dynamic Web Project创建的。

Another way to add the .jar is to right click on your project, and choose Properties -> Java Build Path, click the Librariestab, then click Add External JARs...This will allow you to browse to the path of the .jar file you wish to add.
添加 .jar 的另一种方法是右键单击您的项目，然后选择Properties -> Java Build Path，单击Libraries选项卡，然后单击Add External JARs...这将允许您浏览到 .jar 的路径您要添加的文件。

Also make sure your import org.jsoup.Jsoup;imports are after all the application imports such as import com.google.gwt.core.client.GWT;
还要确保您的import org.jsoup.Jsoup;导入是在所有应用程序导入之后，例如import com.google.gwt.core.client.GWT;
Having the JSOUP imports before those other imports caused errors for deploying an application at one point for me.
在那些其他导入之前先导入 JSOUP 会导致我在某一时刻部署应用程序时出错。

I had the same error now on my Android project. To Fix this on Android, you need to create a lib folder and put the .jar file there
我现在在我的 Android 项目上遇到了同样的错误。要在 Android 上修复此问题，您需要创建一个 lib 文件夹并将 .jar 文件放在那里
