Objet : Re: Problem with Override annotation in tutorial examples
Okay, I worked it out.
Apologies if i have 'polluted' the newsgroup, but i will
explain my mistake
for any other newbies that may encounter the same problem.
Instead of importing the org.restlet.data.Request, I had imported the
simple.http.Request.
When overriding the 'handle(org.restlet.data.Request,
org.restlet.data.Response)' method, this meant the method i
was overriding
with had the signature 'handle(simple.http.Request,
org.restlet.data.Response)' and of course the @Override
annotation barfed on
this.
I hope I haven't wasted anybody's time.

I think/hope that this should be a fairly simple issue to
resolve... :)
I am trying to get into Restlet, and its slow work. I have
been going
through
the tutorials and trying out the example code and I've hit
a piece of code
that
I can't compile.
It is in Section 3:
// Creating a minimal Restlet returning Hello World
Restlet restlet = new Restlet() {
@Override
public void handle(Request request, Response response) {
response.setEntity(Hello World!,
MediaType.TEXT_PLAIN);
}
};
I am new to Java and can only assume this 'new'
instantiation syntax
creates an inline subclass with the 'handle(..)' method
overridden. I've
have knocked up some simple test code and found that you
cannot define new
methods, but you can override existing ones in this manner.
It also seems that the Override annotation is unnecessary,
it simply
generates a compiler error if the method doesn't infact
override a method
in the super class.
THE PROBLEM:
In the above example, I get the following error with the Override
notation:
com\firstStepsServlet\SimpleRestlet.java:22:
method does not override or implement a method from a supertype
@Override
^
The error message does not seem correct though, as I can
create a new
class that extends the Restlet class that overrides this
method and uses
the Override notation, and does not generate this error. It
also executes
correctly.
Any help with this would be appreciated as it seems that
the tutorials
continue to use this form of syntax.
Thanks in advance

Maybe you should try to use JDK 6

Re: Problem with Override annotation in tutorial examples
Thankyou for your quick reply Keke, but I believe I am :
$ java -fullversion
java full version 1.6.0_04-b12
$ javac -version
javac 1.6.0_04
Would you be able to tell me whcih part of my problem indicated to you that
I may not be running 1.6? Perhaps this may shed some more light onto the
situation
Many thanks
