Thank you Gareth, Frank and Richard. It worked... I replaced & with %26 in my servlet and used javascript unescape to to get is back they way it should I tried URLEncoder.encode() the values in servlet but it seems that the unscape is not converting + to spaces. In any case, it works. Thanks so much for your time.
