reading URL parameters in jsp

[payal Jain]

hi,
I am trying to read the parameters passed in URL through jsp.
But when i read them i get the blank value.
my URL is http://localhost:9090/MyTomcat/firstjsp.jsp?bgColor=#FDF5E6.
and my code
String bgColor = request.getParameter("bgColor");

The # sign is a special character and needs to be encoded.

[payal Jain]

can you tell me how to encode these special characters(#&),what code i need to add so that I can get the result.

[Bear Bibeault]

Whatever creates the URL needs to URL encode the values. Just how depends upon where the URL is being generated.

[Paritosh Ranjan]

response.encodeURL("yourURL") does the work of encoding your URL in a correct form.Just check whether it can help with #.

Response.encodeUrl doesn't escape characters.
Its purpose is to embed the sessionId in the URL when session cookies are not enabled.

Look at java.net.URLEncoder.
If used correctly, that will escape the necessary characters.
You will still need to understand when and when not to encode characters or you'll end up encoding control characters that need to be left alone.
