java - apache POI exception in reading xlsx files

Question

I'm using apache POI for reading xlsx files by adding below dependencies

<dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>3.8</version>
        </dependency>

<dependency>
            <groupId>org.apache.xmlbeans</groupId>
            <artifactId>xmlbeans</artifactId>
            <version>2.5.0</version>
        </dependency>

I'm getting following exception while running with jetty plugin even if deployed in tomcat.

I removed the xmlbeans dependency as the maven will automatically download poi dependencies , still the same exception.Any help?

Answer 1

I used poi with version 3.12. The following dependency is also required:

compile 'org.apache.poi:ooxml-schemas:1.1'
