Uploading a file using <s: file> in Struts2

I am working on struts2 application. I have the following in my jsp (say main.jsp) -

<s:file name="sampleDocument"/>
<s:submit action="uploadSample" value="Upload" />

See how my struts.xml is handling the action -

<action name=" uploadSample " class=" UploadFiles">                 
        <result name="success"> /main.jsp</result>
        <result name="input"> /error.jsp</result>
</action>

Everything works well. As the file downloads. But as you saw I am calling the same jsp page (ie main.jsp) on SUCCESS. Its coming, but the <s:file>

text box is blank. I mean there is no filename that I am looking at before uploading. Does anyone know how to get this?

You need your action properties that reflect the parameter names of your JSP. Check out this documentation for an explanation of what properties to look for.

you must define getter and setter functions for fileName. This ensures that the value is populated in the view after it returns from the activity.

The item value <input type="file"/>

is cleared by default for security reasons.
