You need to add the latest jar in the java build path. Check your projects build path and make sure the jar is present there. Do a clean build and clean publish and it should work. If not then you can even try to directly paste the jar in your projects deployment location (LIB folder).
您需要在 java 构建路径中添加最新的 jar。检查您的项目构建路径并确保 jar 存在于那里。做一个干净的构建和干净的发布，它应该可以工作。如果没有，那么您甚至可以尝试将 jar 直接粘贴到您的项目部署位置（LIB 文件夹）中。

您可以阅读有关如何将数据写入 pdf 的教程
create pdf sample hello program
and to read doc file Apache Tika is best :
并阅读文档文件 Apache Tika 是最好的：
have a look to read doc file using apache tika in java:
看看在java中使用apache tika读取doc文件：
i am reading content from doc file and writing into text file but after learn you can write data into pdf .
我正在从 doc 文件中读取内容并写入文本文件，但学习后您可以将数据写入 pdf 。
public class Tikaconvrt {
public static void main(String [] args) throws IOException, SAXException, TikaException
{
Tikaconvrt tc=new Tikaconvrt();
File Re_F = new File("/home/rahul/Documents/212/ANIR.docx");
String F_Name=Re_F.getName();
int eof=F_Name.lastIndexOf('.');
F_Name=F_Name.substring(0, eof);
String s1 = tc.contentEx(Re_F);
tc.files(s1, F_Name);
}
public String contentEx(File f) throws IOException, SAXException,
TikaException {
InputStream is = new FileInputStream(f);
Parser ps = new AutoDetectParser();
BodyContentHandler bch = new BodyContentHandler();
Metadata metadata = new Metadata();
ps.parse(is, bch, metadata, new ParseContext());
return bch.toString();
}
public void files(String st,String fname) throws IOException {
FileWriter fw = new FileWriter("/home/rahul/Documents/txt/"+fname+".txt",
true);
BufferedWriter bufferWritter = new BufferedWriter(fw);
bufferWritter.write(st + "\n");
bufferWritter.close();
}

You are using a version of iText that is higher than 5 (with packages com.itextpdf), yet you are importing classes from packages com.lowagie(yes, that's my name; I'm the original author of iText) that only exist in versions of iText predating iText 5. Hence it is normal that the classes you're using aren't found. You should replace com.lowagiewith com.itextpdf.
您正在使用高于 5 的 iText 版本（带有包com.itextpdf），但您正在从包中导入类com.lowagie（是的，那是我的名字；我是 iText 的原作者），这些类只存在于 iText 5 之前的 iText 版本中. 因此，找不到您正在使用的类是正常的。您应该替换com.lowagie为com.itextpdf.
By the way: the title of your question doesn't match the question because iText doesn't convert Word documents to PDF.
顺便说一句：您的问题的标题与问题不匹配，因为 iText 不会将 Word 文档转换为 PDF。
