Re: sunwjit slows down JDK
This posting reminded me of my many struggles trying to find a neatly compiled list of java properties. Does anyone know if such a list exists for JDK properties? I cannot find it in the documentation anywhere.

My machine with 64MB wasn't enough to run Jini. I could squeeze the basic services into the existing memory (124 virtual memory) with very careful tuning of the "experimental" switches of the JVM. I don't remember which release of JDK 1.2 that was. (There have been too many) I haven't run JDK 1.2 on Linux. However, I did on Solaris and NT. I disagree with the poster who essentially said JDK-s tend to take up equal amounts of memory on various platforms. On NT an instance of the JDK for me only seems to take up 4 MB. On Solaris each intance took up 20 MB for a "Hello World" until I tweaked it down to 4 MB manually. -kornel - Original Message - From: Nathan Meyers <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Cc: Brian Pomerantz <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Friday, December 17, 1999 2:34 PM Subject: Re: Blackdown JDK vs Sun/Inprise >On Fri, Dec 17, 1999 at 03:34:01PM -0500, [EMAIL PROTECTED] wrote: >> >> >> Hi, >> The success of any product depends on the advantages it offers and failure >> always depends on restrictions it imposes.

Hey, I wouldn't have even noticed the memory requirements for long had it not been for my machine getting disabled. In my contracts my clients would usually not accept such waste of memory. Why should we accept it from Sun? -kornel -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
Re: Blackdown JDK vs Sun/Inprise
Dear Nathan, >But, such considerations aside, it is useful to understand what problems >are inherent versus what are implementation details. Some of Java's I do understand memory management. I just don't necessarily want to have to care about it in Java: Java is advertised as an environment which will take the burden of memory mangement over from you. I would like that promise kept, especially because billions of dollars are being invested into this technology and it's being deployed everywhere. As one engineer to another: Would you create an application which manages memory so wastfully? I can't believe you would if you program for a living. Why do you want to silence me when I point out a deficiency in the VM? Why are you defending an engineering oversight? Isn't it in the best interest of Java to point out problems in it? Java seems to be regarded as something almost devine. It is almost sacrilegious to criticize it. I'm an engineer and I won't think along religious lines. Java, while a wonderful engineering achievement and while I was amongst the first to promote it years ago, still has problems, memory management being one of them. I'll think this even if I get stoned for it. -kornel -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

My guess is that LD_LIBRARY_PATH which is the path for sahred libraries does not include the directory where your shared libraries (libserver.so, etc) are.

I vaguely > recall once trying to get jigsaw to work and fleeing in horror. > > Nathan I tend to agree with that. Though httpd (C reference impl) was good I think and all major webservers are still based on it. But Their first Java server wasn't exactly a success. I think they rewrote Jigsaw because the first very early incarnation was really bad. Nathan probably is right that it is not the best choice nowdays when there are so many others. I have used Sun's Java Webserver the most, of Java servers. It is not the best, but perhaps it is the cleanest I've seen. It only has the most imortant features and that makes it easier not to get lost in the directory structure and features. With Java webservers I found their directory structures absolutely awful. I'm currently writing code using JRun with Apache which also suffers from an obsession of logs and property files. For the basic server functionality there are about 10 logs and dozens of property files. It is really bad in that regard. I hear there next version's going to clean that messup a bit, though I'm not sure about that. Otherwise it is usable though. It implements the servlet API nicely. Not very fancy, but free. -kornel - Original Message ----- From: "Nathan Meyers" <[EMAIL PROTECTED]> To: "kornel c" <[EMAIL PROTECTED]>; "Nathan Meyers" <[EMAIL PROTECTED]>; "Pedro Guimaraes" <[EMAIL PROTECTED]> Cc: "Roger Smith" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Wednesday, January 19, 2000 11:50 AM Subject: Re: Java web server > On Wed, Jan 19, 2000 at 09:19:43AM -0800, kornel c wrote: > > Do you guys know about jigsaw from the web consortium.

Re: HELP: using unix-signals?
Hi,
posted from Java developer connection (sorry I didn't fix indentation). The
code works. I tried it, but I created a watch thread instead of using the
main thread.
from http://forum2.java.sun.com/forum?14@@.ee7b71f
= excerpt start here
code NOT tested. but it should not be far from a solution for fasay's
problem.
import sun.misc.*;

env before to leave. */ public void main(String args[])
final Thread theMainThread = Thread.currentThread(); SignalHandler
theOldSignalHandler = null;

is typed try { theOldSignalHandler = Signal.handle( new Signal("INT"), new
SignalHandler() { public void handle(Signal sig)
theMainThread.interrupt(); } } ); } catch (IllegalArgumentException exc) {}
// makes a unused object in the main thread, // sleep on it until wait()
