How are you reading that parameter in your Servlet? – Mark Thomas Nov 05 '13 at 23:18 — Mark Thomas, Nov 05 '13 at 23:18

Per the answer found here: How to escape Hash character in URL

Replace # with %23.

You can find a list of all the reserved characters here: Percent-encoding.

A word on JavaScript encoding

encodeURI(str)

"Assumes that the URI is a complete URI, so does not encode reserved characters that have special meaning in the URI. encodeURI replaces all characters except the following with the appropriate UTF-8 escape sequences:" [1]

encodeURIComponent(str)

"Escapes all characters except the following: alphabetic, decimal digits, - _ . ! ~ * ' ( )" [2]

In your case, you would use encodeURIComponent(), only on your query string, to escape any and all reserved chracters.

!  %21 
#  %23 
$  %24 
&  %26 
'  %27 
(  %28 
)  %29 
*  %2A 
+  %2B 
,  %2C 
/  %2F 
:  %3A 
;  %3B 
=  %3D 
?  %3F 
@  %40 
[  %5B 
]  %5D

If i replace # with %23, do i need to replace %23 with # symbol while getting that parameter in the servlet? — ANILBABU, Nov 05 '13 at 11:14
Possibly define a character encoding scheme on your servlet? http://stackoverflow.com/a/470320/1762224 — Mr. Polywhirl, Nov 05 '13 at 13:12

You would need to encode the parameters that may contain # and then decode back the parameter in server side code.

You can use many resources in the internet to URL-encode strings, like this. In your case, anil#1234 becomes anil%231234.

You need to encode the value(if you are using string concatenation to create the url). in javascript you can use encodeURIComponent() like

encodeURIComponent('anil#1234');//or your variable here

@ANILBABU how is the url generated – Arun P Johny Nov 05 '13 at 11:12
it takes inputs from the user and creates a URL. THe input from the user may contain special characters. – ANILBABU Nov 05 '13 at 11:20
