Hi,

I am having an option to gray out all the components in a panel, if the FTP service is not running.I am able to gray out all the components in the panel except the table in the panel.
I used setEnabled(false), for all these components, but doesn't seem to be working with table.Table still shows to be an active component.Can somebody help me so that I can give this table a grayed out look?
The table is put in a scroll pane, i am disabling scrollpane too.

Thanks in advance.

I have just started the preparations for SCWCD.My doubt is about Apache Tomcat.Is it a web container or a server?In some places I see that Apache is a web server, and that Tomcat is a web container?So I am confused, about this container and server terminology.

Could somebody please explain to me these terms?
Thanks Rob and Jim, my problem got solved by upgrading the java version.And I needed a quick fix too.

Thanks, my issue got fixed after I upgraded to java version "1.6.0_03".

I am not sure, but I think in the beta version, @Override annotation was not compiling while used with implementing an interface.It worked fine when I tried to extend one class.

I've implemented an interface to a class and use @Override for the implemented methods.But while compiling i get error saying "Method has to override a method from superclass".
Can @Override be used just while extending classes or implementing interfaces too?

I am using java version "1.6.0-beta".

Could somebody please help me?

Well, I am a bit confused about how many minimum number of objects are needed for IS-A and HAS-A relationships?
I thought HAS-A needs only one since a class can have its own instance.But then what about IS-A?(Object IS-A Object too, right?)
Thanks Marc,

Actually it was a foolish doubt,after posting only I realized it.I took it as Ford HAS-A Car.That's why.Anyways, thank you.


If you attempt to serialize an instance of Ford, how many objects would be serialized?
Since both Car & Ford(subclass too is Serializable), is it 2?

It is trivial to create an instance of Cricket and assign it to references of types Game and Playable. Then you can call the method via both of those references to see what happens.



Thanks Barry, because I too was having this doubt.
So ,if I am not wrong, our conclusion is that
will invoke the abstract class version.
will invoke the interface version.
Right?

Thanks in advance.
