I get the following errors when I try to read the content of the doc file using apache poi 3.17:

java.lang.IllegalArgumentException: The document is really a OOXML file

I have included xmlbeans-2.6.0.jar and dom4j-1.6.1.jar but the problem persists.

  • Please show the code that generated this exception, along with the filename that you're trying to open. Is it a .doc or a .docx file? – rgettman Apr 18 '18 at 16:39
  • It seems that you are trying to parse an .docx as a .doc. Is your document really a .doc? When using POI there are different classes to parse .doc and .docx. – davidbuzatto Apr 18 '18 at 16:39
  • @rgettman i'll post the code now – sam alex Apr 18 '18 at 16:44
  • @davidbuzatto can't we parse the docx file using apache poi ? – sam alex Apr 18 '18 at 16:45

    Yes you can, but you need to use the appropriate classes to do this. HWPF is used to .doc and XWPF is used to .docx. Take a look here: https://poi.apache.org/document/index.html. Your example is using the XWPF infrastructure, but you are trying to open an .doc file. – davidbuzatto Apr 18 '18 at 16:51
  • @davidbuzatto i can successfully read the doc files using the same program now. well how can i select a docx file or doc file one at a time ? – sam alex Apr 18 '18 at 16:57

    This answer does a bit more than look at file extensions to decide doc or docx: https://stackoverflow.com/questions/47483011/how-to-judge-if-the-file-is-doc-or-docx-in-poi?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa –  Apr 18 '18 at 18:02

This happens when you try to read .doc files when in fact they are in docx format.

In such cases use the XWPFDocument class instead of HWPFDocument.

Cheers! :)
