B4J Question Problem opening Word Document

[hatzisn]

I have a problem opening a word document. I have never tried it before and I do not know what is wrong. I am using a new B4XPages project and this code in B4XMainPage. I also use jPOI 5.01 and Java 19.0.2. I tried different approaches I found in the forum and the error is always the same. In the following spoiler there is the error. Where am I making a mistake?

Spoiler: Error in loading word document

WARNING: package com.sun.javafx.embed.swing.oldimpl not in javafx.swing
Waiting for debugger to connect...
Program started.
Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.

Maybe you need this class library in the java code...

import org.openxmlformats.schemas.wordprocessingml.x2006.main.*;

Thank you for the reply. Here is what I get:

org.openxmlformats.schemas.wordprocessingml.x2006.main does not exist
import org.openxmlformats.schemas.wordprocessingml.x2006.main.*;

XLUtils supports creating Word documents: https://www.b4x.com/android/forum/threads/xlutils-creating-ms-word-documents.131732/#content

You can check its code to see how it works.

In this thread: XLUtils you can read about all the downloads and dependencies for POI.
Make sure you have downloaded the dependencies zip file and unpacked it in the AdditionalLibraries folder.
Include XLUtils library in your project and you should be good to go...
