Hello there,

Have you got all dependencies installed? There are couple of hidden ones needed - think I fell afoul of this when I used poi a couple of years ago. Have you got these two added to your project?

<dependency>
   <groupId>org.apache.poi</groupId>
   <artifactId>poi-ooxml</artifactId>
   <version>4.1.2</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml-schemas -->
<dependency>
   <groupId>org.apache.poi</groupId>
   <artifactId>poi-ooxml-schemas</artifactId>
   <version>4.1.2</version>
</dependency>
