Hi,
Instead of putting the values in the JavaScript array...
1. use looping to store the values in hidden fields
2. concatenate all the values with a suitable delimiter and use hidden form
field to store it...
at the servlet end.. retrieve the hidden form field and use StringTokenizer
class to extract the tokens...
