i.e while getting the value through getValue() cast it to the string object or date object and then call toString() on that.

but the value returned by getValue() is already of String type and value of the cookie is date so it should automatically display date.

Don't you think that it might be helpful to show exactly what "some alphanumeric string" is?

I have just started learning JSP so shoudn't I start from basics? This is the alphaneumeric string which im getting-

then just use that string value to create a date object and call the toString() on it .
because the string value representing the long value.

i think you should use the EL expression support .
instead of using counter=count+1 use ${count} +1

i think it solves your problem

if i understood your problem correctly
you want some code demo showing the how to reverse the elements of an array using only one loop.

here i am using a temporary array also.

assume your main array of type int and referenced with name mainarray

i hope it will help u.

if i understood your problem wrongly ignore this

from examining your code posted at the very first glance it is clear that the method should be named doGet() not goGet() .

try this change if it doesn't works then try with the using the post method.

i think you can use the jsp standard tag libraries .
i am not sure of this tag <jsp:cookie> but there is a way to set cookie from a jsp with out using scriplets.

if you are using tomcat6 .
the default installation directory will be:
c:\program files\apache software foundation\tomcat 6.0.
in this directory you should find the lib(libraries) directory there you will find servlet.jar or tomcat-servlet.jar and also the main containers responsible for running of servletengine.

extract the jar file and set the class path to the extracted directory or just copy the jar file to the webapplication you building.

ok thanks to all

but my problem is i need to write it to the byte stream( a bmp file as a pixel value) and then retrieve this value.

which i did in 'c' easily.

my main problem is how to store the value 255 in a byte in java.

in my theme :
i am making a reader and writer for a bmp image . so i am unable to read the unsigned byte values(means to read & write value >128) in single byte only.

i.e like i want to store byte b=255; in any way and this value should be written to the image.
my problem of reading was solved by readUsnsignedByte()

but problem of how to write this value to the 255 in single byte only is not addressed

(in brief i want to set the gray level of a pixel in bmp to 255 using java and read the same as well using only one byte)
so please any one can help me
