and i tried all most all the possibilities
i declared the following thing in all the 3 jsps

<html:form action="/esmtLevel" enctype="multipart/form-data" styleId="estimateLevel012Form" >

my getter and setter methods are

public FormFile getPartImage() {
return partImage;

public void setPartImage(FormFile partImage) {
this.partImage = partImage;

and i declared bean field as FORMFILE element only

form past 2 days i was having problem vth this one
and any help would be appereciated[

Try using the ActionForm bean with the FormFile attribute only with the JSP that actually performs a file upload. Use an ActionForm that does not contain this attribute for the other JSPs.

why because i am moving back and fourth very frequently and when i move like this i need to keep up the values alive when i move back and fourth
i.e when user comes to that screen once again he has to get the values what ever he selected in the begning
