How do I pass a value for an array element to a bean from a form? The class that my bean uses has an array textFields[407]. I have 407 textfields in my jsp file. I used a loop to make the textfields. So, it looks something like this:
The problem lies in the NAME. What should be its syntax so i can say that I am passing the value of the ith textField in the jsp file to the ith element of the array in the bean?
Is this possible? or should I do another kind of approach?

please help me. 
I tried:
NAME="textFields["+i+"]"
NAME="textFields["+<%=i%>+"]"
NAME="textFields[i]"
NAME="textFields[<%=i%>]"
I'm running out of ideas. Could this approach be impossible? but it would be hell if I am gonna give 407 unique names in the bean for the 407 textFields. That isn't approprite. there should be an easier way.
