Answer 1

java doc says
NoClassDefFoundError Thrown if the Java Virtual Machine or a
ClassLoader instance tries to load in the definition of a class (as
part of a normal method call or as part of creating a new instance
using the new expression) and no definition of the class could be
found.
The searched-for class definition existed when the currently executing
class was compiled, but the definition can no longer be found.
org.apache.commons.fileupload.FileItem is a class in FileUpload component of Apache Commons which is missing in your class path. Add following maven dependency for FileUpload component in your pom.xml.
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>x.x</version>
</dependency>
