i know !!!
but when i try to implement it and the compile it i get a general
error saying my main module cant be loaded
so baby ! show me any class you create that inherites from List and of
course compile it !

You try to compile it for deployment or are we talking about
the hosted mode? if the latter, what's the error-message
showing up in the details-pane if you click on the main-entry

I come to the impression that you think that I'm some kind
of support-guy you have the right to use for free. That's
not the case, so please work on your way of asking questions:
- Don't use exclamation and question marks excessively
- Give as much information as possible to be able to
reproduce or at least understand your problem
- Don't forget: It's you, who want to be helped, so ask
in a way motivating as much people as possible to
help you.
I never needed to create a new implementation of java.util.List
but alway use ArrayList for the client side of the application.
Most likely java.util.List is not part of the client JRE that
is converted to Javascript leading to the error (but that's just
a guess, the error-message in the details-pane should clearify
that).
i dont think anyone is working for me i just found what seems to be a
very big bug in gwt since for some reason its not possible to
implement the list interface and i belive it is a potential problem

Documentation is clear :
"Google Web Toolkit includes a library that emulates a subset of the Java runtime library. The list below shows the set of JRE packages, types and methods that GWT can translate automatically. Note that in some cases, only a subset of methods is supported for a given type."
java.util.List is in the emulated list but you'd better check if all methods are supported
I tried to write an empty implementation (no time to waste) of List<String>, and GWTCompiler seems to be happy with it, so I'd suspect an error in your code (using something else that is not supported by gwt jre emulation).
By the way, you're asking insistingly without giving any valuable information for us to help you ... IMHO that's impolite.
1) Is your class in a "client" package? by that, I mean does the
parent package have a *.gwt.xml file, and does it declare the
SmartQueue package as a source package?

yes its in a client package and i also tried to create an empty
implementation of INTEGER and it didnt work
did you try to run the module with the empty List<String> in hosted
mode

im sorry but i was under some presure i have a close deadline and
thats pretty much the only problem idid you create an anonymous class
or a class that implements the list

If you are using a version of GWT < 2.0 this error appears because the standard GWT List interface doesn't have the subList method. You can either remove the @Override annotation from that method, or extend AbstractList instead of implementing List directly (generally considered a better option anyways).
You could also upgrade to GWT 2.0-rc, which has the subList method included in the interface definition.

thanks i removed the override and it worked can you please tell me why
did act like that since the eclipse filled out the implementation
acording to the interface and if the method is not suppored how did
it got into the imlementation in the first place

Eclipse fills in methods based on the JDK installed, not the GWT emulated JRE. GWT's implementation of the JRE sits in the package com.google.gwt.emul.java, not java.
