Java web server
Does anyone know of a Java web server for Linux?? Is there only the apache module. or is there actually a java web server from sun that has been ported to linux.

Java web server
Hey all I am trying to install a JAva web server on a Redhat linux box, wher edo I start?? _ When I have a kid, I want to buy one of those strollers for twins. Then put the kid in and run around, looking frantic.

Re: Java-Linux I18N
Actually, I have noticed one problem that so far is a mystery to me.
Somehow under Linux (with JDK 1.2.2) something seems to get lost when
trying to write to an OutputStreamWriter with a specified encoding, if
the string is not iso-8859-1, but my machine is. Sun has some sample
code on their I18N (actually, the very last example) that I cannot get
to work on Linux. No idea why, and I spent many many hours trying to
figure it out.
The code is supposed to write some Japanese String (in \unnn notation)
to an OutputStreamWriter, like:
OutputStreamWriter out = new OutputStreamWriter (new
FileOutPutStream("test.txt"), "UTF8");
out.write("\u672c\u8a9e");
Then the code is supposed to read from that test.txt file by doing the
reverse, with an InputStreamWriter that specifies the encoding. There's
no way I could get this to work; my pretty Japanese string gets
completely garbled, no matter what encoding I specify, including if I
don't specify one at all (in which case it would use 8859_1.
So far, I've only succeeded in writing a shift-jis file, for example, by
doing something like
byte[] testArray = testString.getBytes("SJIS") and then writing that
array directly to a FileOutputStream (again starting with a testString
in \u notation).
So maybe someone here knows what could be going on under the covers??

Mixing heavy (Java3d) and light (Swing) components
Hi, I am trying to work with Java3D and Swing on Linux. I was able to run some 3D programs but stuck when I tried to place JPanel and Canvas3D on the same Frame. I could see my Canvas3D objects very well, but my JPanel object always lies behind the background color in the main Frame. I could see some small part of it, if I resize the Frame, I could see (sometimes) larger part of it, but I could not place it on front. My heavy and light objects don't overlap, nevertheless I could not see all of them. I read Amy Fowler's article about mixing heavy and light components but the example only tells about JPopupMenu. JPopupMenu.setDefaultLightWeightPopupEnabled(false); What I can do about JPanel? Currently I add JPanel to Frame - I could not make it otherwise. Do you have any ideas? Here is a piece of code: . HelloUniverse helloUniverse = new HelloUniverse(); // heavy component 3D DisplayImagePanel displayImagePanel = new DisplayImagePanel(); // JPanel displayImagePanel.setBounds(0, 100, 128, 128); displayImagePanel.CreateImage(); Frame frame = new MainFrame(helloUniverse, 400, 400); frame.add(displayImagePanel); frame.setVisible(true); frame.validate(); . -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

JNI and Dead Thread on Linux
Hi: I got a few questions on JNI on Linux. It would be appreciated if someone could help. Suppose a shared library file has a function that is used to do hardware I/O, say hard drives R/W. A Java application uses JNI and calls this native function in .so file twice to R/W two separate hard drives at the same time. In this way, we should have two new threads (light weight processes) t1 and t2 created (am I right?). Q1: Since Java application and two newly-created threads (t1 and t2) share the same memory space, if t1 messes up memory space and hangs, then Java application and t2 will hang too, right? Q2: If the answer to Q1 is "right", is it possible to protect Java application and t2 and prevent them from hanging after t1 is hung if we use JNI? Q3: If the answer to Q2 is "no", then do you think out-proc solutions (i.e. leave native functions in different memory spaces) like CORBA, TCP/IP and DCOM (not sure it's available now or not on Linux) are better than in-proc solution like JNI, so we can separate native functions in different memory spaces and prevent one from messing others? Is there any potential problem? Thank you in advance. Lee -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Calling into native code doesn't create new threads - it just moves the flow of control from the Java interpreter into some other native code. After the JNI method returns, you're back to executing native code in the Java interpreter.

Tritonus 0.1.82 available
Hi, Tritonus, the open-source inplementation of JavaSound for Linux, has a new release. Major reasons for this release are: Easier Installation --- There is now a 'configure' script that automatically determines most parameters important for the build process. Installation is now mostly now follows the configure - make - make install pattern. Support for jdk1.1.x Tritonus now builds and runs with jdk1.1.x. It has been tested with Blackdown jdk1.1.7_v3 and jdk1.1.8_v1. In jdk1.1.7(a?) there are bugs in javac that prevent compilation. Generally, you need the 1.1 collection framework from http://web2.java.sun.com/beans/infobus/ (near the bottom of the page). Many thanks go to Peter Pilgrim who did the main work for this by writing a script that converts the collection classes' package names. Additionally, he detected and fixed many small bugs. Other goodies - There are several improvements under development and/or waiting for merge into the main source tree. - Midi support: see file README.midi - MP3 decoder: see file README.mp3 - Format converters/codecs (thanks to Florian Bömers) - pure-java client-side library for esd (thanks to Atsuhiko Yamanaka) The latest version is downloadable from (see "File Releases"): http://sourceforge.net/project/?group_id=1390 There are now daily development snapshots og Tritonus at ftp://tritonus.sourceforge.net/pub/tritonus/. If you found bugs, have suggestions, want to contribute or whatever, you can contact me: mailto:[EMAIL PROTECTED] If you're interested in taking part on the development, you may have a look at the Tritonus dveloper page (sorry, not very up-to-date): http://rupert.informatik.uni-stuttgart.de/~pfistere/tritonus/developer.html Have fun! -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

I didn't find what I needed in it, which is why I wrote to the newsgroup. If I missed something in it which would have helped me, I apologize. The HOWTO says to *** 1.Create a link from the new ld.so to /lib/ld-linux.so.2: ln -s /usr/i486-linuxglibc2/lib/ld-linux.so.2 /lib/ld-linux.so.2 *** I cannot do this because what /lib/ld-linux.so.2 is currently pointing to is in use by others. All of the binaries (java, javac, ...) have the complete pathname /lib/ld-linux.so.2 hardwired in them. I could edit the binaries, replacing lib with another 3 letter directory which contains a link to my new libc, but step 2 would hurt me: *** 2.Edit /etc/ld.so.conf. You need to add path to the lib directory the new libraries reside in at the end of the file, which will be /lib, such as /usr/i486-linuxglibc2/lib for the choice above. After you have modified /etc/ld.so.conf, run ldconfig -v *** I cannot take this step, either, because wouldn't doing this change the dependencies of other programs? For example: ldd /usr/bin/make libc.so.6 => /lib/libc.so.6 /lib/ld-linux.so.2 => /lib/ld-linux.so.2 If I edited /etc/ld.so.conf, then libc.so.6 that make needs will no longer point to /lib/libc.so.6, but will point to the libc.so.6 which resides in the directory of whatever I specified in /etc/ld.so.conf. I cannot do this, because I cannot make changes to other programs (such as make) without changing a program someone else didn't want changed. If any of my statements above are incorrect, or if the HOWTO states how to deal with this problem and I am just not getting it, then I apologize; however, what I wrote above is what I BELIEVE to be true, and therefore I am stuck, which is why I wrote to the newsgroup in the first place. jason -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Terrible native thread performance
Hi folks, I've just installed two versions of the JDK1.2.2 for linux: Sun's RC2, and Blackdown's RC3. I am experiencing the wierdest behavior I have ever seen for a JDK. Here is what I am *used* to seeing. We run Java all day long on Solaris Sparc and x86 and Windows NT. With green threads, things are slow as hell, and the processors are kept very busy, even when the program is idle. With native threads, everything zips along nicely. Here is what I see with Linux. I am running on a freshly installed RedHat 6.1 machine. With either JDK, running in native threads is absolutely crippling. There seems to be a serparate JDK process ID for each running thread, or otherwise something is casuing it to fork 15 times. Of these threads four or five of them just hammer the CPU, leaving the whole machine at a crawl. Actual performance of our Java GUI isn't too bad, but it's no where near where it should be. Switch to green threads. With Sun's JDK it's like lightning. Processor utilization is practically nill, and the GUI is extremely responsive. With Blackdown's JDK, processor utilization is also very low, but GUI responsiveness is very low as well. I have looked through all the FAQs I could find, tried the various combinations of env variables. Anyone else experienced this behavior? Really odd. Any fixes, work arounds, or do I just hope something miraculous happens between the release candidates and the release?

You are seeing an artifact of the Linux threading model: native Java threads are mapped onto kernel threads and kernel threads look a lot (to ps and friends) like separately forked processes.

On Linux, threads have separate entries in the process table. The Inprise JDK you're getting from Sun has a better JIT, which could explain your green-threads performance differences. As for native threading, the Sun/Inprise version is known not to support native threads reliably. The Blackdown version does, and whatever it is you're experiencing - hammering the CPU - is not the normal behavior (at least, not that anyone's reporting). Have you been able, using (for example) -Xrunhprof, to identify threads that are sucking CPU?

Segmentation fault problem
I wrote the following little test when I was tracking a
OutOfMemoryError exception in the earlier release of
blackdown jdk.
I am trying it now using Jdk1.2.2 RC3. I'm running under
RedHat Linux 6.1 (glibc 2.1.2).
The test allocates and prints one million T2 objects. Each object
is released after the print() method. It has a finalizer that
bumps a static counter.
It runs fine until iteration #259656, then it crashes with a
Segmentation fault. This number stays constant even if I vary
the lengths of strings in the messages, etc.
Has anybody seen anything similar? Is this a known bug?
I'm writing a persistent service that uses a lot of fine-
grained objects, so this is important to me. Any help is
greatly appreciated.

No there is no idltojava compiler available for Linux. (It's not a Java application, and the source is not released, not even to the Blackdown team(?).) The currrent JDK1.3beta has a different ORB. And the IDL compiler for that ORB is called idlj and IS part of the JDK1.3beta. The Win32 version of the old idltojava (for JDK1.2beta2, I think) does run inside Wine. So if you really really want to do your idltojava part of the work on Linux, you can kludge it this way: 1. Write your *.idl; 2. Run 'gcc -E' over it (or find a cpp that runs under Wine); 3. Copy the resulting file to where Wine thinks is the 'C:\' drive; 4. Run idltojava on that file in Wine; 5. Copy the result back; 6. Of course Wine messes up all the file names (all lower case letters), so you have to change them back to the proper case by hand. I was crazy enough to do the above once, and it did work. But I've decided that it's easier to use a near by Windows 95 machine for the task. Maybe one could write a bash script to automate the above process. -- Weiqi Gao [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Dan, A big part of the threads problem on Linux stems from the pthreads implementation that's available in glibc.

Re: Java-Linux I18N
JackWang -
The font.properties file typically only maps Java font properties
("MonoSpaced", "SansSerif", etc.) to the actual fonts available on the
client machine. Changing the font.properties file on the server makes no
sense, as the server in a client/server or applet/servlet or whatever
architecture would not be responsible for displaying fonts to the
client.
BUT - font.properties file should only be important if you want to
display fonts for character sets that are not the native encoding of the
operating system under which your JVM is running, for example, if you
want to enable users with an US English operating system to see Japanese
text in your applet (or, say enable Japanese users to be able to see
Simplified Chinese). I am fairly certain that, if your internet user is,
for example, running a Japanese OS with a Japanese version of Netscape
(or whatever client it is that provides the JRE), then everything should
work. The crucial point here should be whether the browser (in a
browser-based application) is localized, so it might not work if the
Japanese user has the English version of Netscape installed (although it
is also possible that the English Netscape installer checks what
operating system locale it is being installed on and then selects the
correct font.properties file to be used, I don't know the answer to
that). And then of course, if you are distributing a JRE yourself with
you app, you can and should take care of these things during
installation.
If you have access to a localized machine, try
http://www.renzop.com/localeviewer.htm - I just put together a quick
test applet for the main Asian languages and Russian - if you see the
strings when you select either one of Japanese, Simplified Chinese,
Traditional Chinese, Korean, or Russian, you should be all set for those
languages. I'll test it out myself from work tomorrow.
Let me know.

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.
