Exception while uploading a .jpg file from ValidatorForm through struts action

[Ashima Beri <as...@gmail.com>]

Hi All, 
I am trying to upload a .jpg file through my struts action. 
Below is my set up 

In the jsp : 

<html:file property="filePath" size="20" maxlength="200"/> 


In the form I have a FormFile property as : 

class MyForm extends ValidatorForm{ 
          private FormFile filePath; 
          // corresponding getter and setter 
} 


On submitting my jsp i get the following exception.

I have absolutely no clue how to debug this. Any suggestions are very
welcomed.
