Re: how to catch stdout
Here's one way of trapping stdout from an unrelated program. I'm pretty
sure there's better way, but this works in Blackdown 1.2v1.
Process process = Runtime.getRuntime().exec("yourprogram");
process.waitFor();
// getInputStream() returns the input stream connected to the normal
// output of the subprocess.
BufferedReader in =
new BufferedReader(new InputStreamReader(process.getInputStream()));
while((line = in.readLine()) != null){
System.out.println(line);
// Or whatever
}

I appreciate what blackdown is doing. But it's a bit frustrating to not know what's going on when you're livelihood depends, to some extent, on the software that they are putting out. I'm not asking for working software, I just want to know what's going on so I can make a decision on whether to use their software.

Re: Emacs and java...
Nice plug for O'Reilly, Albert ;-), but why this channel ?
Personally I avoid emacs when ever possible having used vi for years (ok,
decades). But - I recently came across a REAL programmers editor called
slickedit while looking for a Java code beautifier - see www.slickedit.com
This really made me sit up - it support emacs and vi (not to mention that old
dos favourite brief) editing modes - including regular expressions. Good
support for Java/C/C++/et al, and includes a great code beautifier. Even
supported on Weird operating systems begining with W, but smile :), it also
runs under X.

String to char conversion
Hi I've looked everywhere (except in the right place) and I can't find something that should be so obvious when you tell me it will smack me in the face and I'll hide in shame for a year! I have a string that contains the characters \u201a - that is a six character string. How do I convert this to a single Unicode char ? I would have expected the Character class to have a method valueOf (String), but it doesn't. Failing that at least a constructor that takes a string arg, but not to be found. This is stupid. There must be a simple elegant solution... Sorry this is a purely Java question on this channel but I *am* running under Linux ;) All the best Jerry

Announce jrex v1.1 alpha
Hi >From the number of requests for info on the Java 2 port, it would seem that there are many other out there who are under pressure to move to Java 2. I've now developed a remote executor which allows for remote compilation of java. We will use this until Java 2 is release and stable, so we can move development on. Our environment is that we have a nice powerful Linux box, but use NT workstations. Using the remote executor we can retain our Linux development environment but submit compilation to the workstation. We can live with running the compiled program under NT only for the time being. If this sounds as though it might help you, drop me a request and I'll mail you the source. Who knows, it might even take some pressure off the Java 2 porting team.

Compilation hardware
Dear all, I've spend the last week or so trawling for info on CPU's, motherboards, chip sets et al, with the intention of upgrading my main linux machine. This machine (currently a now aging P90) sits in a cupboard and acts as a file server and compilation (Java and C) machine - i.e. a developers systems. Graphics are simply not an issue, as a separate machine acts as an X server. Needless to say both these machines are running Linux. A further machine runs NT to provide the (obligatory) Windows platform. There is a bewildering plethora of choice out there and I would be interested in seeing what opinions and experiences the java-linux community had to offer in respect of selecting components for a compilation machine, specifically, CPU Chip set Motherboard Memory It does seem that most CPU design is driven by the need of the games players on one hand, or the business community on the other and the benchmarks used seem to reflect that. This seems to me to miss the needs of developers somewhat, as we invariably require far more out of our systems than (pardon the term) 'mere users'. Not only must a developers machine meet the requirements of the systems being developed (which is a quite variable issue) they must also provide the shortest compilation times possible. My main concerns are (not necessarily in this order) reliability compilation speed longevity (upgrade ability etc.) price Any reasonable argument for your preferences would be most welcome.

Re: How to measure efficiency?
I've had similar problems measuring bandwidth. The greatest difficulty was the limited resoution of the available timers. It's a darn shame that a high resolution counter isn't available given all these fancy hardware. Milliseconds! Pah! You can do an awful lot in a millisecond. Ever since the Pentium was release there have been high resolution counters available - anyone written some code to access them ? - back then it was all restricted access only! Does Intel give a damn now ?

JDK 1.3, Tomcat 3.2.1, and CLASSPATH settings....
Two days ago, I installed JDK 1.3.0_02. Yesterday I installed Tomcat 3.2.1. I tried JSPs and they failed. I found a Tomcat FAQ that suggested I needed to add tools.jar to my CLASSPATH. So, I added JAVA_HOME/lib/tools.jar But that didn't work. Investigation on my machine shows that JAVA_HOME points to /usr/java/jdk1.3.0_02/jre there are lots of jar files in $JAVA_HOME/lib such as rt.jar But there are also several jar files in /usr/java/jdk1.3.0_02/lib such as tools.jar So, 1. What should JAVA_HOME be set to? 2. What is tools.jar? 3. Why the two different lib directories? 4. Is there a FAQ for this mailing list (I'd hate to repeat questions that have already been answered.)

CLASSPATH anomolies
I have recently downloaded and installed Steve Byrne's JDK 1.1.3 and have run into several strange problems associated with setting of the CLASSPATH environment variable. On two of our systems, one running RedHat4.0, the other running Caldera's Standard OpenLinux 1.2, I cannot get 'javac' or 'appletviewer' to function unless I completely remove the CLASSPATH variable; when it is set to the "correct" value, niether 'javac' nor 'appletviewer' will function correctly! I'm wondering if you have seen this before, and if so, if you can tell me what the "correct" procedure should be? Thanks, -jerry solomon
Netscape and linux java
Although the latest version of Netscape Navigator, 4.05, claims to be using JDK 1.1.2, I have had problems with it not recognizing most of the event handler classes in the linux JDK 1.1.5 version that I run locally. In particular it cannot find such things as mouseMotionListener, etc. Anybody seen similar problems? -jerry solomon
appletviewer screen location
I believe someone mentioned this problem recently, but I do not recall any responses indicating how to "cure" it. We are running Linux JDK 1.1.5v7, and when we use 'appletviewer' to checkout java code the viewer invariable comes up initially rather close to the upper left corner of the screen; then, after about 2 seconds it jumps about 20 pixels up and 20 pixels to the left. This leaves the viewer only partially visible; and, since the upper part of the viewer is not visible, there is no way to reposition or even 'quit' it! Wondering if there is some way to control this annoying behaviour?? Thanks much, -jerry solomon
RedHat, libc, and glibc
Well, I suppose I should add my own observations to the general confusion over glibc and libc. I recently installed JDK1.1.5v7 on one of our RedHat 4.2 systems using the libc version, and it performs quite well with no problems (so far). I could not get the glibc version to work at all! Also, on this system the CLASSPATH environment must NOT be set in order for JDK to work properly! Perhaps someone will find this observation useful.-) Jerry Solomon
feedback on JDE's
Hello List, I have spent the past several weeks trying out two commercially available JDE's, Simplicity (datarepresentations.com) and SuperMojo (penumbrasoftware.com). Although I have not done an exhaustive evaluation, I am coming to the conclusion that these (and probably other) JDE's are not terribly useful for more than "toy" projects. I would greatly appreciate hearing from anyone who has actually used either of these products to produce real, substantial project code, and what their experiences might have been. Thanks in advance, -jerry
