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.

Most probably you are trying to do some string manipulation by passing some boundary values out of its range.
