Hi, i tried this for .doc file and i am getting the below error.
org.apache.poi.POIXMLException: org.apache.poi.openxml4j.exceptions.InvalidFormatException: Package should contain a content type part [M1.13]
at org.apache.poi.util.PackageHelper.open(PackageHelper.java:41)
at org.apache.poi.xwpf.usermodel.XWPFDocument.(XWPFDocument.java:120).

Please tell me how to resolve this

I think you'd have to use HWPF for .doc files.

HWPFDocument wordDoc = new HWPFDocument(new FileInputStream(filePath));
int noOfParagraphs = wordDoc.getParagraphTable().getParagraphs().size();

could you tell me how you define poi dependency in your pom? The one I pull from maven has no module named xwpf or hwpf. THX

he cyjj. El problema es porque usas la librería equivocada. debe usar poi-ooxml.


org.apache.poi
poi-ooxml
3.7-beta3

My pom file is below that worked for me after much research over the internet collecting pieces together:

           <dependency>
	    <groupId>org.apache.poi</groupId>
	    <artifactId>poi</artifactId>
	    <version>3.9</version>
	</dependency>
	
	<dependency>
                 <groupId>org.apache.poi</groupId>
                <artifactId>poi-scratchpad</artifactId>
                <version>3.9</version>
           </dependency>
    
	 <dependency>
	    <groupId>org.apache.poi</groupId>
	    <artifactId>poi-ooxml</artifactId>
	    <version>3.9</version>
	</dependency>

Hope this will help.
Thank you,
