Struts html:file tag problem

Question

Hi,
I have already posted but couldn't get the solution. So just incase if anyone can suggest something, it would be appreciated.
On the form, there is a browse button and a submit button. The normal procedure of clicking on the browse button, and then submit button using mouse works fine. But what we want is , When mouse is pointed on browse button and a "ENTER" button is clicked on keyboard, the file browse window pops up . When we click submit button, that file should be submitted and get processed. The problem is when mouse is pointed on browse button and a "ENTER" button is clicked on keyboard, the file browse window pops up and then when I click submit button, the text field is cleared off instead of being processed.
I tried all sorts of javascript but still don't know why the text is erased once the submit button is clicked.
Any suggestions??
The code related to this is:
function focus1() {
if(document.all.uploadFile.click())
return true ;
else
return false ;
<html:form method="post" action="/SubmitTrans.do" enctype="multipart/form-data" focus="uploadFile">
Choose the file
<b>Select File</b> <html:file property="uploadFile" onfiltered=' return focus1();'/>
<html:submit value="Process"/>
</html:form>
Thanks in advance.

Because the bean util is using reflection to lookup the methods for getting and setting the value. Thus it can't find getter and setter methods for the member named File. But if the member is named file, then it finds getFile() and setFile() because they follow the naming convention. If your not familiar with reflection and java beans, you should take a look at some brief tutorial.
Example:
private String username;
public String getUsername() {
   return username;
public void setUsername(String name) {
     username = name;
}
