    package com.webportal.admin.action;
    
    import java.io.File;
    import javax.servlet.http.HttpServletRequest;
    
    import org.apache.commons.io.FileUtils;
    import org.apache.struts2.ServletActionContext;
    import org.apache.struts2.interceptor.ServletRequestAware;
    
    import com.opensymphony.xwork2.ActionSupport;
    import com.webportal.admin.model.ImageDetail;
    
    public class SetInfo extends ActionSupport implements ServletRequestAware{
     	private ImageDetail imageDetailBean;
    	HttpServletRequest servletRequest;
    		private static final long serialVersionUID = 1L;
    	public String execute() throws Exception
    		{
    	boolean done=upload();
    		if(done)
    		return "success";
    		else
    		return "input"
    	}
    	private boolean upload() { 
    			try {
    		            String filePath = servletRequest.getSession().getServletContext().getContextPath();
    		            System.out.println("\nServer path:" + filePath+"                   "+imageDetailBean.getLogoName()+"......."); 
    		            File fileToCreate = new File(filePath, imageDetailBean.getLogoName());
    		            FileUtils.copyFile(imageDetailBean.getLogo(), fileToCreate);
    		        } catch (Exception e) {
    		            e.printStackTrace();
    		            addActionError(e.getMessage());
    		 
    		            return false;
    		        }
    		        return true;
    				
    			}
     	
        public ImageDetail getImageDetailBean() {
    		return imageDetailBean;
    	}
    
        public void setImageDetailBean(ImageDetail imageDetailBean) {
    		this.imageDetailBean = imageDetailBean;
    		
    	}   
        public void setServletRequest(HttpServletRequest servletRequest) {
    			this.servletRequest = servletRequest;
        }
    }
    

my beans class is

    package com.webportal.admin.model;
    
    import java.io.File;
    
    public class ImageDetail {
    	
    	private String logoContentType;
        private String logoName;
    	private File logo;
        
    	public File getLogo() {
    		return logo;
    	}	
    	public void setLogo(File logo) {
    		this.logo = logo;
    	}
    	
    	
    	public String getLogoContentType() {
    		return logoContentType;
    	}
    	public void setLogoContentType(String logoContentType) {
    		this.logoContentType = logoContentType;
    	}
    	
    	
    	public String getLogoName() {
    		return logoName;
    	}
    	
    	public void setLogoName(String logoName) {
    		this.logoName = logoName;
    	}
    	
    public ImageDetail() {
    		super();
    		System.out.print("from the constructor Image detail");
    	}
    
    }

    	<s:form action="settingHeader" cssClass="form" enctype="multipart/form-data" method="post"  >
    	       <s:div cssClass="fileinputs">
    				<s:file  key="imageDetailBean.logo"  />
    		   </s:div>
    	</s:form>

my property file

   
 imageDetailBean.logo=Logo
   

struts.xml

    <action name="settingHeader" class="com.webportal.admin.action.SetInfo" method="execute" >
    			<interceptor-ref name="fileUpload">
            		<param name="maximumSize">2097152</param>
            		<param name="allowedTypes">
                			image/png,image/gif,image/jpeg,image/jpg
            		</param>
        		</interceptor-ref>
        		<interceptor-ref name="defaultStack">
        		</interceptor-ref>
       			<result name="input">/success.jsp</result>
