i have never tested it, its only an idea:
Test.java:
------------------------------------
public class Test{
@Inject
private Response response;
StreamResponse onActivate( Object[] parameters ) throws IOException{
TextStreamResponse textStream = null;
if( parameters == null || parameters.length != 2 )
{
textStream = new TextStreamResponse("text/html", "this page doesnt
exists");
response.sendError( 404, null );
textStream.prepareResponse(response);
}
return textStream;
}
}
------------------------------------
