File Upload not working as expected with javascript,ajax, struts

I have an application where I have to upload files in a dynamic table. My code is as follows:

JSP code:




JS code:




MasterBean.java:




FileUpload.java




My Problem is , This code works sometimes and does not on other times.

1.When it works.. it uploads the first file and then when I retry uploading another file , it gives the details of the first file and uploads the first file again. The second file is not getting uploaded.

2.When it does not work , It gives a null pointer exception. and getMyFile() shows null in the console.

Can anyone please let me know what is wrong with my code? and explain me exactly what is happening here?? Thank You in Advance!

note: working in eclipse galileo.
