OT: Howto get the 'pwd'
Hi All, If i am running a java application, is it possible for me to find out the complete dir path from where the application was launched? -Karthik. +-+ | Karthik Vishwanath, Junior Research Fellow, | | National Centre for Biological Sciences, TIFR Bangalore, India. | | Ph[Off]: (080)8561657/58/59/71/72; 8462895, Ext. 3231 | | mail to: [EMAIL PROTECTED] | +-+ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

I have a big problem with Sun
It seems that Sun will not support bug reports that occur in the platform independent parts of Java since I'm using Linux. If you report a bug and say your on Linux they say its not a supported platform. Even though I've been reporting bugs in the Swing. I can't believe Sun forces me to use NT ! Anyway just though I'd warn everybody on the list that if you report a bug don't let them know your on linux they will drop it. Pissed off.

Re: Help!Help!
Hello everybody I think your problem is not about paths. I use 1.1.6 release, and my libjava is in /usr/lib/jdk-1.1.6, so my JAVA_HOME and my JDKHOME variables point to that directory.

Just thinking about VM
Hello everybody. These are just a few personal thoughts about java and virtual machines and I thought it could be interesting share them with other linux users. I was just updating my beloved XEmacs, hacking and fixing a few minor problems, configuring my system to the detail -- I really love it. Then I started to think about the lisp machine [ Xl]Emacs holds inside. It's a real virtual machine: bytecompiled, portable and fairly eficient. What's the difference with jvm, for example?. jvm has another language, and a bunch of good libraries to support it. What if lisp (emacs, common, scheme or whatever) had libraries like the java ones ? Lisp is flexible, portable, and applications like gimp use it to create plug-ins wich I think is enough to demonstrate it's power. Also can be Object oriented (flavors, and the like). With communication libraries, GUI, and the free software community could have a free equivalent of Java (a Lisp machine in Mozilla x.xx ?) I like Java (the way I liked Warp, despite BigBlue marketroids) but sometimes I get a bit angry when we suffer Sun rarities. What do you think about it ?

Using Syslog from Java
Has anyone implemented the equivalent of the syslog commands -- openlog, syslog and closelog-- in Java. If so, any pointers in terms of the protocol. Thanks, Cynthia Jeness -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
Re: Using Syslog from Java
Cynthia, Well, not exactly. What I have done is to make a daemon out of our Java application. I don't have much experience with threading under Linux, but someone mentioned on this list that signal handling can be tricky since the thread that receives the signal may not be the thread listening for it (I'm quoting from memory here, but I don't think I'm too far off base). A daemon, of course, should respond to signals, so I created a parent process in C to handle it with a child launching a Java VM via the Invocation API. To make a long story short (sorry for the winding answer), I created two pipes before forking and exec'ing the child. The first pipe is tied (with dup2) to both STDOUT and STDERR of the child process and the second pipe is tied to STDIN. All output from the Java application is routed to syslog. When the parent receives a signal to shutdown, it closes the second pipe. The main thread of the Java application is blocked reading System.in. When it detects the close, it simply cleans up and shuts down the application. For a simpler application, I'm sure you could implement a logging method to syslog via JNI without going through the trouble explained above. :-) Good luck, Russ [EMAIL PROTECTED] on 04/05/99 11:40:24 AM To: [EMAIL PROTECTED] cc:(bcc: Russell Pridemore/Lex/Lexmark) Subject: Using Syslog from Java Has anyone implemented the equivalent of the syslog commands -- openlog, syslog and closelog-- in Java.

Re: Using Syslog from Java
Actually, what I would like to be able to do (if possible) is to contact "syslogd" directly from Java using UDP. I want to avoid native code since we need to have this work across all the platforms which support syslogd. So does anyone know if it is possible to communicate to syslogd through UDP and, if so, where might I find the protocol documented. Cynthia [EMAIL PROTECTED] wrote: > Cynthia, > > Well, not exactly.

C/C++/Java/Pascal syntax is a lot more popular and easier to learn - despite being a lot more verbose in some cases. Everybody understand iterating the loop with for, many people has problems with grasping car/cdr conctept to the point of being able to use it efficiently. So lisp is for hackers. If I would have too choose I will rather think about Smalltalk or Eiffel to replace java, not lisp. Artur -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

You apparently missed the lengthy debate regarding bzip2 that has plagued this list for the last week.
