Answer 1

Sounds like you do not have the correct dependencies in you project. POIXMLTypeLoader comes with POI 3.14-Beta1 and the ooxml-schemas:1.3 reference that class.You have the following options, you can add any of this dependency in your project:

• use poi 3.14 beta1

   <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>3.14</version> </dependency> 

• use ooxml-schemas 1.2

   <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml-schemas</artifactId> <version>3.14</version> </dependency>
