Examples of org.apache.struts2.dispatcher.multipart.MultiPartRequestWrapper

org.apache.struts2.dispatcher.multipart.MultiPartRequestWrapper
Parse a multipart request and provide a wrapper around the request. The parsing implementation used depends on the struts.multipart.parser setting. It should be set to a class which extends {@link org.apache.struts2.dispatcher.multipart.MultiPartRequest}.
The struts.multipart.parser property should be set to jakarta for the Jakarta implementation, pell for the Pell implementation and cos for the Jason Hunter implementation.
The files are uploaded when the object is instantiated. If there are any errors they are logged using {@link #addError(String)}. An action handling a multipart form should first check {@link #hasErrors()}before doing any other processing.
An alternate implementation, PellMultiPartRequest, is provided as a plugin.
