java - WAR on tomcat cannot find deploy.jar in jre -

-

i have deployed application on tomcat war file. @ 1 point using urlencoder com.sun.deploy.net encode http parameters.

message = urlencoder.encode(message);

this compiles fine. deployed application tries access method receive 

java.lang.classnotfoundexception: com.sun.deploy.net.urlencoder

why that? understand urlencoder class belongs deploy.jar of jre since java 1.3 (i using 1.7) tomcat doesn't seem find ...

what have do?

i being incredibly stupid

it should have been

import java.net.urlencoder;

rather import com.sun.deploy.net.urlencoder; plain wrong. works, of course!
