How to extract Docx (Word 2007 above) using Apache POI

Question

Hi, I am using Apache POI 3.6. I have already generated the code.

XWPFDocument doc = new XWPFDocument(new FileInputStream(file));
         wordxExtractor = new XWPFWordExtractor(doc);
         text = wordxExtractor.getText();

         System.out.println("adding docx " + file);
         d.add(new Field("content", text, Field.Store.NO, Field.Index.ANALYZED));

Unfortunately, he generated an error.

Exception in thread "main" java.lang.NoClassDefFoundError: org/dom4j/DocumentException
at org.apache.poi.openxml4j.opc.OPCPackage.init(OPCPackage.java:149)

It seemed like he was using a constructor

XWPFWordExtractor (OPCPackage container)

but not this →

XWPFWordExtractor (XWPFDocument document)

Any wonder why ??? Or any idea how I can extract .docx and then convert it to a string?

Answer 1

You need to add the dom4j library to your project library or project libraries

Answer 2

It looks like you don't have all the dependencies on your class path.

http://poi.apache.org/overview.html, , dom4j OOXML. , , , ... POI, ooxml-libs.
