Question

我第一次尝试使用PDFClown。如在自述文件中所写，我尝试通过以下步骤导入PDFClown项目在我的Java Workspace，Eclipse IDE中 1）File =＆gt; import ... =＆gt;现有Project into Workspace =＆gt;然后我选择了下载的PDFClown Zip（版本0.1.2 Beta）

的Java文件夹

在此之后我在我的包浏览器中有5个项目，4个由PDFClown加上我的项目。现在，我得到38个错误;最后一个是关于我原始项目中HelloWorld的实现。

编辑：对于凌乱的错误报告我很抱歉，如果有人能以更友好的方式帮助展示，我会很高兴

编辑：其实我已经下载了org.apache.commons.fileupload Jar，然后将它包含在Project =＆gt;中属性=＆gt; Java Build Path =＆gt; Libraries =＆gt;添加外部罐子现在我的错误少了......但它真的必须那么复杂吗？

Answer 1

如果您只想在项目中包含PDF Clown，则不需要导入其分发项目（包含完整源代码和预编译的jar文件）：您需要做的只是选择您可以在发行版（PDFClown / java / pdfclown.lib / build / package）中找到预编译的jar ，并将它们放在项目的依赖项中。

或者，如果您想尝试分发样本（基于CLI，基于GUI和基于Web），那么您必须遵循自述文件，考虑到（作为您的错误报告显示）如果你想使用网页样本（因为你已经知道网络项目是如何工作的，对吧？）你必须设置你的网络服务器（BTW， commons-fileupload-1.2.jar已包含在项目中，无需搜索）。如果您不知道eclipse中的Web服务器设置，那么请查看Web上可用的万亿教程，否则您只需关闭eclipse中的Web示例项目（pdfclown.samples.web），这样就不会再烦扰您了。您可以愉快地运行CLI和GUI示例！
