Serialization between Java 1.1.4 and Java 1.4.1
It seems to me to be in some kinda trouble. I wanted to implement
communication between Java applet and Server through sockets and
Serialization. So, I serialize Object, send it to server which deserialize
it with no problems. In other direction problems came out since Object
serialized under Java 1.4.1 seems to be not deserializable under Java 1.1.4.
(MS VM). If applet si run under J2, there are no problems, but I cannot push
people to download some 15MB of new JRE just to accomplish my requirements,
especially if applet needs not implementation of features of new JRE...

Now I'm thinking abou...How advanced is java 1.6 with respect to java 1.1 ?
I've learned java 1.1 using a relatively old video tutorial and
realized it only later.
Is java 1.1 similar to java 1.6 or is it radically different ?
And if its similar, what additional features do I need to learn ?

I am guessing that version difference is the reason. Is it?

Oh, yes, absolutely, of course; what else could possibly
be amiss? I mean, just *look* at the text of your forty-second

When attempting to RMI between a 1.4 client and a 1.5 server ( with a
1.5 interface, remote object, stubs and skeletons using the -vcompat
rmic flag ), I get the following error:
Handler (no security manager: RMI class loader disabled)
The plot thickens. The 1.4 client will connect to the 1.5 server if I
run the 1.4 client classes in a 1.5 jvm. However, when I run the 1.4
compiled classes in a 1.4 jvm I get no joy.
Any ideas anyone?

I even saw Java 1.2 exam is still available on sun's site. I
guess it makes more sense to take Java 1.5 exam since it is
the latest Java version. Can either Java 1.4 or 1.5 exam
be the prerequisite for other advanced Java exams?

I'm searching for a documents describing the things to get in mind so
that if I build now

with minimum changes afterwards.
Examples, links, documentations, whitepapers .... are welcome.
I'm talking primary about JBoss.

I don't recommend you to use ejb2.1 as it is completely different from
ejb3, as EJB3 beans are just empowered POJOs.
Instead, you probably should use j2ee1...Call Java 1.5 Jar from Java 1.4 JVM ?
Is it possible to call a Jar file complied with Java 1.5 from a 1.4 JVM
I have done a wee bit of testing and I get :
"class file has wrong version 49.0, should be 48.0"
To be honest, this is preretty much what I expected, but I need to do
some investigation on this.
The reason is this:
App A <----> App B
App A is a 3rd Party component we use and it's being moved to Java 1.5
(we have no access to the code base)
App B uses a JAR file from App A (subclasses off it and calls APIs)
However, App B is Java 1.4 and is part of a framework that that is 1.4.

I'm writing a Swing app, and I wanted a way to filter certain rows out
of a JTable. I search Sun's API to see if they had any facilities for doing
this, and I while I couldn't find such an API for 1.5, there is one for 1.6:
So I have a bit of a dilemma here. I don't want to have to "wait" for
1.6 to come out. I don't want to actually use a beta version of 1.6 (forcing
my clients to do the same). But I don't want to implement this functionality
