NoClassDef error is coming while PPT creation

Aspose.Slides Product Family
1

I am using Aspose.Slides for Java (16.11.0). It is a Dropwizard application.
In my pom.xml,

<dependency>
<groupId>com.aspose</groupId>
<artifactId>aspose-slides</artifactId>
<version>16.11.0</version>
</dependency>

<repository>
<id>aspose-maven-repository</id>
<url>http://maven.aspose.com/repository/repo/</url>
</repository>

It is running fine in my local system, but I deploy the same JAR on my server. It is throwing error:

StackTrace:
