Show us line 29 of PublicServlet. Are you looking for a character in a String that isn't there ? Or are you in a loop ? If you are in a loop, then show us the whole loop.

At this place he is calling the method processRequest which is getting the error...

>>com.ccim.servlet.PublicServlet.processRequest(PublicServlet.java:53) i.e. we need to look at the line 53 of processRequest.. most probably you are trying to do a substring of a string which is not there or is not long enough...
Show us the code & we will be in a better situation to hep

in at com.ccim.servlet.PublicServlet.processRequest(PublicServlet.java:53)

there is a substring functin being called on a string that is empty or your substring is starting looks something like substring(-1,1) or something and that's making the page throw up. Check to make sure the string is not empty before doing your substring or has at least the expected amount of characters.
