Hi i have face the same problem and sorted out here is the solution:
Struts2 reads the file prepare tmp file and delete the tmp file after execute method
solution:
jsp code
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@taglib uri="/struts-tags" prefix="s" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
<s:head />
</head>
<body>
<s:form action="fileUpload" method="post" enctype="multipart/form-data" >
<s:file name="userImage" label="User Image" />
<s:submit />
</s:form>
</body>
</html>
