servlets - decoding string

[sumit vashishta]

I am able to encode the string in first servlet but unable to
decode it in another servlet.
Even if I import java.net it throws exception that URLDecoder class not found.
can't find the reason for this.
I am using javawebserver.
Is there any other method to decode.??
thanks in advance.
