Subject: java to C translator
Java to C translator alpha-001 for Solaris 2.x available
j2c is a translator from java .class to C program.
j2c produces(generates) C program from .class to build a.out executing
without java interpreter.
As simple benchmark program, it makes fast about from 2 times to 6
times(with -O). (You know Sun's implementation of java interpreter is
good, I think)
If you have java benchmark program, please send to me.

Mark,
this is not the fact. You *can* define a constant like this:
static final int HEREITIS = 99;
Creating a constant that nobody can meddle with is one way, but consider
the following, which is more elegant (I think ;):
class Safe {
private boolean locked = true;
private int combination = 456;
public boolean isLocked() { // here is one accessor, which returns the
// the status of *locked*
return(locked);
}
public void keyLock(int thisCombination) { // here is another one
if (thisCombination == combination) unLock();
}
private void unLock() {
locked = false;
}
Safe() {}
}
So if you write:
Safe aSafe = new Safe();
you can't access the combination like this:
int = aSafe.combination;
you also can't say:
aSafe.locked = false;
won't work.
.............................
Did this answer your question? I hope, I didn't misunderstand your point.

Hi Jonathan,
1)
saving to and reading from files is not possible from applets if
they run under Netscape (security). With the appletviewer it works
though.
What I'm currently coding is saving through email, and loading
through an URL. It's not ideal, but I seem to be able to get it
to work.
Reading and writing are performed with FileOutputStream and
FileInputStream (how unexpected!)
2 small examples:
FileInputStream fi = new FileInputStream(fileName);
aByte=fi.read();
fi.close();
FileOutputStream fo = new fileOutputStream(fileName);
fo.write(anInt);
fo.close;
You most probably want to know how to write Strings etc.
I still have to find out, but it will have something to do with
reading and writing arrays of bytes.
2)
I don't know how to use java as an CGI program, but I figure that
it works exactly the same as starting other scripts; you might
even be able to start it from a perl script.
I used a mailto cgi script to send mail within java by doing this:
try {
URL u= new URL("http://icg.resnet.upenn.edu/mailto.cgi?to=you@there
&from=me@here&subject=mysubject&body=mybody");
u.openConnection();
InputStream is=u.openStream();
while (is.available()!=0) {
is.read();
}
} catch (IOException e) {
System.out.println("exception");
}
Perhaps there's an easier way, but this works.
3)
see the included file (I don't know exactly what you mean by option buttons)
take care,
Lein

317 root 1 0 160 296 196 S 0.0 0.6 0:00 -ksh
( memory still about 15 percent..... single threaded as well, compared
to the multithread XmasTree applet )
This seems a little high, don't you think?

I've been playing around with the URL classes.
I have a simple program that receives a URL from

dumps the stream to a file.
The only URL's I get to work our with the http protocol.
I cannot get it to accept an ftp or gopher URL.
I've tried URL's like:

any ideas?

I think this is a great move from Gate (who has a lot of problem lately
with wall street's big firm ) and the timing of this "deal" is excellent
but I'm afraid that this move is only a trick from gates to turn more
attention on is browser production. I wouldn't be surprise if a rename
"blackbird" would reappear in the near future...

A lot of user been trying to get java to with in Netscape 2.0b3. Will
Dr Java. Found a way.
First download the JDK. from sun.
After install the JDK you need to set two environment variables.
I install the JDK on my c drive so you may have to change my samples
the two variable are:
HOME=C:\JDK\JAVA
CLASSPATH=C:\JDK\JAVA\CLASSES;.
and in your home directory create a directory called ".hotjava"
You should add the environment variables to your autoexec.bat but
adding the following lines.
SET HOME=C:\JDK\JAVA
SET CLASSPATH=C:\JDK\JAVA\CLASSES;.
After doing all of the above things will run great as long a the java
class was made with teh beta.

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.

Subject: System.loadLibrary() problem
What's the story w/ System.loadLibrary and Netscape? I'm running
Netscape 2.0 Beta 3 on SunOS and have written an applet that uses
a class containing some native methods. I've built the native
implementation as well as the Java "stub" class, but when Netscape
loads my applet it can't find my shared library.
I've included the directory where my library is in my LD_LIBRARY_PATH
and even tried putting it in my PATH variable. But to no avail! I
still get "# Applet exception: error: java.lang.UnsatisfiedLinkError:
no libjavaAK.so.1.0 in shared library path". Note: I've tried
specifying the library as javaAK, libjavaAK, and libjavaAK.so.1.0 and
none of these work. What am I doing wrong?
Also, here's one I haven't researched to much so it may be easy...
How does one force Netscape to reload an Applet. Pressing the Reload
button doesn't seem to do it. At best you get a new copy of the HTML,
but no new applet. Restarting netscape is really time consuming during
debugging.
Thanks,
Clint

Use the java.awt.MediaTracker class. The documentation for it is online:
http://java.sun.com/JDK-beta/api/packages.html
http://java.sun.com/JDK-beta/converting/images.html

The getWidth() method will return -1 until the width of the image is
known. This has very little bearing on when the image will be completely
loaded since the width is one of the first things at the beginning of
most image file formats. Also, it's bad practice to poll waiting for
information, especially when there are much better methods to use (i.e.
the MediaTracker).

Subject: Looking for Graphic Artist for Java
I was thinking of starting a part time business of creating web pages
for companies. This would include Java programs and JavaScript. I can
do all the programming and creation aspects, but I was looking for
someone who might like to join me in a partnership with this business
who can design graphics for the web pages. Someone located in the
VAarea is preferred. Skills in graphic design a must, also a plus if
you know CGI and Java.

I think this is a great move from Gate (who has a lot of problem lately
with wall street's big firm ) and the timing of this "deal" is excellent
but I'm afraid that this move is only a trick from gates to turn more
attention on is browser production. I wouldn't be surprise if a rename
"blackbird" would reappear in the near future...

Subject: Linux and Java
I am in the process of writing some Java apps, but would really like to
do it under Linux (1.3.9) instead of Win95(personal preference mostly) but
all of the ports that I have seen have been in ELF format. Does anyone know if
there is an a.out format port to Linux, or should I go ahead and get the
source from Sun to do my own port? Has anyone attempted this before?
This is my first post to the list, so please excuse any faux-pas.
Thanks

Check out StringTokenizer in java.util:
String s = "user=smith&password=master";
String d = "=&";
StringTokenizer st = new StringTokenizer(s,d);
while (st.hasMoreTokens()) {
println(st.nextToken());

You can read or write to the server using cgi and/or a custom server.
You just have to roll a lot of your own code. If you've written cgi's
before and understand Java's URL and Socket classes it's not
partiucalrly difficult.
