Using Appletviewer 11/27/95
Hi all!
I have installed the Windows 95 JDK-beta on my home computer. The problem
that I am having when I try to run any demo file that is included in the JDK
package is that Appletview constantly looks for the Network connection in
order to start the applet.
I do have an Internet connection through the PPP acount.
How do I run the applets using Appletviewer on my computer without any sort
of Internet connection?
Please help!

Subject: Re: Fundamental flaw in Java library distribution scheme
the reason we don't do dynamic overload resolution in the
way that you suggest is that it moves the detection of overload
ambiguities to runtime. we want these ambiguities to be
detected at compile time, in the spirit of a strongly typed
language.
if you have all the source, you can recompile.
in the many cases where you don't, you can still run
the old .class files and they will dispatch to the method
that was defined in the class against which they were compiled.
under your proposal, they would get runtime errors, and you
would be in a real fix, not having the source.

ow stable are the byte-codes and the design of the Java abstract cpu. Is
this something that is going to undergo change when Java is no longer free?
What has Sun said that is certain? Comments invited.
PS: I am doing work building the CoffeeMaKer product suite and want to
know if the 'vmspec' and other Sun documents might represent a
'work in progress'. That would be alright if the changes are
announced. But it would be bad if the Sun started acting like
some who dropped out of Harvard...

Hmmm, this is a good point. However, hacking the problem by making
execution semantics dependent on the compilation history would seem
to me worse in the long term than eliminating the root of the
problem: overloading. It might be painful to do it at this point, but
I can assure you that overloading would be the least-missed feature
from C++. Even most C++ programmers would agree that it is the single
biggest source of complexity in both C++ and Java. Java would be a
*much* simpler and more elegant language without it, and would then
have a clean, history independent semantics.
I know that no one at Sun really wants to hear that right now, but learn
from the C++ experience: look at all the unanticipated complications that
overloading caused in C++. Who knows what problems still lurk?
Languages can take years of large-scale use before all the consequences
are clear; claims for stability in the Java spec are almost certainly
premature.
Think about the impact of even small problems in the language design in
5 years. If I was Sun I would not put *anything* into Java that was
not incredibly well understood, and vetted by the academic community.

Since you didn't make a constructor for class A, a default constructor
was added:
A() {
super();
}
Since super() maps to Container.Container() and since the default access
mode is friendly (not protected), that constructor was not visible to you
outside of the java.awt package and so the class definition failed.
If you read the doc comment on Container's constructor you will see that
Containers were not meant to be subclassed outside of java.awt. Try
subclassing one of the other types of Containers, such as Panel, Window,
Dialog, FileDialog or Frame.

to be honest, we have spent the last 5 years having arguments like
this, and are very aware of, e.g. hoare's classic paper on language
design, which says roughly this.
every feature has been proposed to be in or out many times;
we have reached the point of exhaustion... someday we'll write
a book reproducing parts of the discussion.
in particular, we discussed taking out method overloading.
i was in favor of this, but it judged
to be very useful for the simple cases,
namely t.print etc.
saying t.printint, t.printreal, ... makes programs less
readable not more, and readability is a major goal of the language.
for the more complicated cases we made the (compile-time) rule
compatible with the more sophisticated rule used by languages
like dylan/cecil. we did this because it seemed to reflect the
negative experience in the lisp and self communities from more complicated
dispatch (e.g. prioritized, etc.) dave ungar (who suffered through
this in the self world) helped us to understand the issues and i believe
we "got it right".
in the end, as actually practised there seems to be no problem
with overloading. what you describe as a "fundamental
flaw" is probably more accurately a "curiosity".

Subject: setIconImage
Has anyone sucessfully used setIconImage() with the Beta under Win95/WinNT?
Looking at code in the appletviewer, I've tried to do something similar.
From within the Frame I'm doing:
img = getImage(new URL(panel.getDocumentBase(), "icon.gif"));
setIconImage(img);
The getImage routine does the same thing as the appletviewer's getImage. The
image retrieved is non-null, but doing the setIconImage results in no
visible change. Is there a bug here? Or am I just not doing something right?

Subject: Getting Native Methods to work with HotJava...
I'm having some trouble getting the Win95/NT Alpha3 version of HotJava to
work with my Native Method DLL. It appears as if the call to LoadLibrary() is
failing (gracefully and silently though). I can actually get the native
method to work by running my debugger (VC++ 2.2) on the DLL while launching
HotJava as the running EXE for the DLL (a debugger option). But when I run
HotJava alone my native method calls don't work. I'm assuming since when run
in the debugger, VC actually finds and loads the DLL, HotJava has no problem
loading the DLL a second time. But when run independently, HotJava apparently
has problems locating the DLL. I've tried placing the DLLs in the Windows &
Windows\System directories, as well as the Java\Bin directory, but no luck.
Any suggestions?
- -Brad
By the way, does anybody have an answer for why Netscape doesn't plan to
support Native Methods in Navigator? I think they think it's a security
issue... but it seems that their plug-ins or standard old helper apps would
have the same security problems as a native method.

A Windows 95/NT detail. Note that, based on the timing of the repaint
requests, you may end up repainting/exposing more than you intended. For
instance, requests to repaint two disjoint geometries may end up
repainting/exposing the union of the two geometries because the individual
Windows WMPAINT messages may get compressed.
We had the damndest time trying to figure this out.

... an alternative? ...
I read somewhere, maybe on this mailing list, that Sun is writing a Java
version of their Workshop development environment which is currently
available for FORTRAN, C, C++, and Ada. The interesting thing about
this is that it is being written in Java. I assume from this that
"Workshop for Java" will run on a Macintosh as long as you have a Java
bytecode interpreter. Is Sun going to release a free Macintosh Java bytecode
interpreter?
Of course, the Sun Workshop product could be much more expensive than the
Metroworks product.

Hello,

I'm programming JAVA for our company. I have only one problem :
I wrote some applets. They all run perfect in the appletviewer. I'm using SPARC and PC. All the
applets run in both the appletviewers.
My problem : To give our costumers the chance to use the applets it has to be possible to run my
applets in the Netscape2.0b3 !!
My problem : They don't run in Netscape, the axception :
# Applet exception: can't load: class XXXXXXXX not found
So, I can run all the applets from the web (for example the applets from GAMELAN) but not my own
applets. Also the applets included in the JDK-developpers kit won't run in netscape. They run in
the appletviewer.
Can you help me please ?????

I don't recall that, but since Sun is keeping Java closed, it might be
possible. But seeing as how they agreed to put the stuff in with
Metrowerks, I dunno. Besides, if you're used to developing on
CodeWarrior, it makes sense to just drop in the Java libraries and code
away. Nothing could be easier. Unless you paid someone to do it.
Yikes, that sounded like a commercial.

And since with CodeWarrior you wouldn't be getting *just* Java, but you'd

Easy for you to say Mr. I Get An Educational Discount! ;-)
If you're not interested in using Pascal can you delete that part to save
disk space? If so then maybe you could do the same thing to the C and C++
portions if you only want to use Java. I'm currently a C++ programmer but
if I could save money by not buying that part of CodeWarrior that would be
great.

Try following code....
class tempstruct {
int x;
int y;
public tempstruct() {
this.x = 0;
this.y = 0;
}
}
tempstruct xy[] = new tempstruct[100];
for(int i = 0;i < 100;i++)
xy[i] = new tempstruct();
tempstruct X = new tempstruct();
tempstruct Y = new tempstruct();
tempstruct Z = new tempstruct();
If you have any problems, please let me know!

Subject: AVI player
We've had little luck turning up any information regarding an AVI/movie player
within Java. Has anyone else come across anything? Jose Pena
<Jose.A.Pena@jpl.nasa.gov> provided an alternative - an AVI plugin demonstration
from Netscape - which can be found at:
http://home.netscape.com/comprod/development_partners/plugin_api/
Since we've heard nothing about Java and AVI support, we'd like to try this
Netscape plugin sample - however, our group will not have a Visual C++ environment
(needed to compile the sample plugin code) until the New Year. We use Prolog, Gnu
cpp and Java - we've yet to make use of Visual C++.
Can anyone compile the code and email/post the result? We'd greatly appreciate
the help - and will relay our experience with Netscape Beta 2/Java to anyone
interested by private email.
Thanks for any help,
Damion jl Hankeh
