Java Port Status Request

Java Port Status Request

Post by Tim Bas » Wed, 29 Nov 1995 04:00:00



Hello World.

I just downloaded the linux-java port from the blackdown site
and have made little progress (probally old libs); then subscribed
to the linux porting list at blackdown with no response from
their majordomo......

I am getting a sinking feeling that the multithreaded Java code
is not porting smoothly to linux..... can anyone bring me up
to speed on this?

Tim

I don't think that this was the question, correct me if I'm wrong; I
think that what Alex is looking for is the development system, not a web
browser (although I guess If you have the first you could make the
second, so Netscape co. might know tricks we don't).

I'm VERY new to java, and would be interested in knowing more. Is this
java port really a port of Sun's API?

well, im not completely sure ...
you could be right
but it is nice to know that LINUX/X can now see the nifty JAVA apps...

well, someone please correct me if im wrong on this:
 i dont think there is any "development system"
 from what ive seen, looking at http://java.sun.com and scanning html
sources it seems that java apps are just like HTML tags, in that they are
(or not) interpreted by the browaer.  Most of the "development" i think
would be just learning the commands and how to write the app.  near as i
can tell from looking at the sources (only got N2.0b3 yesterdat, not much
time yet), it seems that the java APIs are just like some C code that is
loaded by the browser (or not)

correct me if someone knows more about this than i do...

: I'm VERY new to java, and would be interested in knowing more. Is this

im not sure about that either...
it seems, to me, that it is Sun's API... but i havent looked that closely
at anything and got interrupted the last time i tried reading the docs on
java...

Its been able to do that for a while now...

You need to go back and read a lot more carefully.  You describe
LiveScript, an embedded language in netscape and www pages.
Read about *java*, a full featured language that happens to be
attachable to the web as just one (simplistic) application.

Wrong, JAVA code is compiled into a Virtual Machine language, that
appears to be a stack based system. The JAVA->VM compiler (JAVA language
appears to be very C++ like in nature, if not based on C++) is only
currently available for Solaris 2.5 and MS-Windows. Whether this porting
is referring to the compiler I don't know, but I have the VM instruction
set here with me, and I am considering trying to write a simple JAVA
program in VM assembler, and if that works, maybe writing my own JAVA
pseudo language :)

Did you have to do anything special to get it to work?
I tried installing it, and it seg faults every time it loads an URL
with a Hava applet in it... ;-(

Hello again....

What I was looking for, in the original post was the up-to-date status
of the JDK port to linux (java compiler, class libs, etc...)

Thanks,,

Tim

I'm having the same problem with a java page under v20b3:  

Quote:> Starting program: /usr/local/bin/netscape

> Program received signal SIGSEGV, Segmentation fault.

I'm running kernel l.2.5 with libs slightly order (from 1994).
Any ideas?      Thanks,   Ed Swarthout

An interesting thing to do would be to make the Java VM a target
platform for GNU C, have been thinking on this lately.

Netscape requires that you carefully follow their readme's instructions
re the .car file.. and that you are running in 8bpp X =(

1. Java, Java, Java, Java, Java, Java .....

In the systems being developed here, everything is coded in Java. There
are about 100 Java applications each running its own virtual machine.

I'm supposed to work with test and performance analysis of these systems
and I'm using tools that log system behaviour on process level.

The problem is that all I see is 100 processes named Java with some
small variations in command line parameters.

Is there a safe way to alter the process names either at startup or at
runtime ?
What could be the consequences of doing such a thing ?
