in pom.xml add this:

<dependency>
 <groupId>commons-fileupload</groupId>
 <artifactId>commons-fileupload</artifactId>
 <version>1.3</version>
</dependency>
<dependency>
 <groupId>commons-io</groupId>
 <artifactId>commons-io</artifactId>
 <version>2.2</version>
</dependency>

in web.xml add this:

<filter>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
</filter-mapping>

If you get this error:

io.undertow.server.RequestTooBigException: UT000020: Connection terminated as request was larger than 10485760

change the max-post-size parameter:

Configuration: Subsystems Subsystem: Web/HTTP - Undertow Settings: HTTP


<subsystem xmlns="urn:jboss:domain:undertow:5.0">
<buffer-cache name="default"/>
<server name="default-server">
<http-listener name="default" socket-binding="http" max-post-size="1000000000" redirect-socket="https" enable-http2="true"/>
