JSF 2.2 introduced the javax.faces.component.HtmlInputFile component and associated h:inputFile component tag. The FacesBridge needs to support this feature in a Portlet 3.0 environment using the new javax.portlet.ClientDataRequest#getPart(String) method.

The javax.servlet.annotation.MultiPartConfig annotation cannot be supported because it is designed to be placed on a servlet class. However, the TCK should test the <multipart-config> element in WEB-INF/web.xml as described in the Java EE 7 Tutorial.

Example Code:

fullPagePostback.xhtml

<h:form enctype="multipart/form-data">
	<h:inputFile value="#{backingBean.uploadedPart}" />
	<h:commandButton value="Submit" />
</h:form>

xhrPostback.xhtml

<h:form enctype="multipart/form-data">
	<h:inputFile value="#{htmlInputFileBacking.uploadedPart}" />
	<h:commandButton value="#{i18n['submit']}">
		<f:ajax execute="@form" render="@form" />
	</h:commandButton>
</h:form>

BackingBean.java

import javax.servlet.http.Part;

public class BackingBean {

	private Part uploadedPart;

	public void setUploadedPart(Part uploadedPart) {
		this.uploadedPart = uploadedPart;
	}
}
