运行代码

 1 package webViewer;
 2 public class Test {
 3     public static void main(String[] args){
 4         Word2Pdf.word2pdf("http://172.16.8.80/file/4.docx");
 5     /*File f=new File("C:/Program Files (x86)/Apache Software Foundation/Tomcat 7.0/webapps/generic/web/file/pdf1.pdf");
 6     if(f.exists()){
 7     f.delete();    
 8     } else{
 9         System.out.println("无文件");
10     }*/
11     }
12 }

运行以上代码可以正常生成想要的pdf文件

但是将java函数放到jsp中

如下

Apache Tomcat/7.0.70

经上网研究，解决方法是：tomcat的lib库中缺少junit.jar包

涨到Eclipse中junit.jar包如图：

将该jar包拷贝到tomcat的lib目录中如下图

最后重新启动tomcat即可正常生成pdf。
