Recompilation only when needed
I have been trying to get javac (1.1.7 for linux) to recompile only those java-files newer than their class-files. Sun's documentation tells me that the "most-recent-change-times" of the files are checked if both the java- and the class-files are found in -classpath or CLASSPATH, but it doesn't seem to work. Is this a problem with the linux port of the javac in JDK1.1.7 or am I doing something wrong? I'm trying to get rid of a big nasty makefile which doesn't work properly so any help is appreciated. Have I got it right that one shouldn't have to use make, only javac, to get proper recompilation? /Jonas Holmberg, Forget-it AB -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

This should surely exist... javax.swing.JEditorPane should be able to display rtf, I think. I haven't tried it myself, though. /Jonas Holmberg -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
How to trap signals?
How can I make a method being called before the jvm exits when killing the jvm (or pressing Ctrl-C if its in the foreground)? I suppose a pure java way is out of the question? What is the least OS dependant way? What I want is to do some cleanup before stopping a server written in java only. And it must perform the cleanup if the computer is shut down, i.e. when the jvm is killed.

Re: serial connection.
Hi, I think what you're looking for is the JavaComm for Linux (http://www.interstice.com/~kevinh/linuxcomm.html). I've tried it very recently (talking to a modem through /dev/ttyS0) and rxtx version 1.3-4 worked fine with Redhat 6.0, except I didn't get it to find all of my serial ports. The machine I used had about twenty serial ports and javax.comm.CommPortIdentifier.getPortIdebtifiers() only found /dev/ttyS[0-3] (the "internal" ports on my main board). It didn't find for example /dev/ttyD0 which is the first "external" serial port. It did however find /dev/ttyd0 (and a lot of other /dev/tty-files that don't even exist) which I couldn't talk to. I can only use /dev/ttyD0 if i rename it to /dev/ttyS[0-3], but that's no solution, of course, since I still can't use more than four ports. Has anyone else had this problem? I also tried it on RH5.0, which has a older c-lib, but then I had to use rxtx version 1.2-2, and it was much, much slower and I didn't get it to work properly. So I recommend using libc 2.1 (e.g. RH6.0) and rxtx 1.3-4. /Jonas Holmberg, Forget-IT AB Wayne wrote: > > Hello, > Sometime ago I seen an API for serial connection, but when I went > to the blackdown site I couldn;t find anything.
