jdk1.2 web site
I know everybody asks when the jdk1.2 for linux will be released. This mail is not one of them. There was a post from a blackdown member that he wants to put a site about the status of the jdk, now I am waiting hard for it. Could you put up the site, even if it doesn't contain more than nothing, would like to see it otherwise I have to search for it in the blackdown site every day! Thanks P@ -- - Save software competition, use Linux and Java! mailto:[EMAIL PROTECTED]

Dear Sir, We could not down load the JDK and 'URL not found' message is displayed on the screen. Could give helph to get the JDK. Thanks for helph Hothiappan K
Wierd results using binfmt_misc
I have recently installed binfmt_misc on my linux system using kernel 2.2.1. I have this game application I've written. It lives in its own package in its own directory one level down from ./usr/local/java. Following the suggestions of people here, I have gotten into the habit of NOT defining classpath variables but using the -classpath switches in javac and java. Therefore I had to rewrite the "javawrapper" that comes as a sample with the binfmt_misc documentation. Now for the wierd part. It all works just fine when I am logged in as root. But when logged in as myself, java reports that it can't find my class. What could cause this? I have loaded up my javawrapper script with a bunch of echo statements and am convinced that it produces the same output under both logins. Neither as root nor as myself do I have a CLASSPATH variable defined. So what else could it be? Or is it just a bad idea to use a package member class as the class holding main()?

I, an author of shuJIT, don't think that shuJIT is usually faster than TYA. Which of the two JITs is faster depends on kind of applications. I'm evaluating Java implementations of candidates for AES.

Most likely, if you built under root, it does not have world read or execute on the files and/or directories. (Actually, the .class files do not need execute but they do need read) >Or is it just a bad idea to use a package member class as the class >holding main()? No, I do that all the time. It works well. I do not, however, use my system under "root" *except* when absolutely required (as in, when doing admin work). This is a good habit to be in since it tends to reduce your chances of really getting messed up or having some unwanted access into your system. It also helps identify things like access rights issues in your directories and files since non-root users actually are held to them.

Running with another locale
Hi, does anybody know how to set the locale other than using -Duser.language=something? I know that the Win JVM respects the locale of the OS, but the Java port does not seem to care (i.e. when I set LANG=de I still get en as user.language). Can anybody tell me whether there is another way than the one above?

117a installation grief
I having problems with installation of the 117a JDK installation. I get the following when I try to run any of the executables: ls: not: No such file or directory /usr/local/jdk117_v1a/bin/../bin/i586/green_threads/java: can't resolve symbol '_Xglobal_lock' /usr/local/jdk117_v1a/bin/../bin/i586/green_threads/java: can't resolve symbol '_XUnlockMutex_fn' /usr/local/jdk117_v1a/bin/../bin/i586/green_threads/java: can't resolve symbol '_XLockMutex_fn' I am running Redhat 5.2 with the default "server" installation. I understand that the symbol problems involve an incorrect library (although I don't know how to fix it). I tried setting the NS_JAVA variable and this gets rid of the symbol errors, but I still get the "No such file or directory" message and the all the executables crash with the following: SIGSEGV 11* segmentation violation stackbase=(nil), stackpointer=(nil) Full thread dump: NULL (TID:0x405100b0, sys_thread_t:0x80a1278, state:R) prio=5Killed Thanks for any help.

java shell script
Greetings,
I'm having problems running java from within a shell script. The java
application mostly runs, but I've noticed that it does not receive a
^C interrupt and it cannot read from stdin when invoked this way.
Typing "java ..." directly at my bash prompt does not demonstrate
this problem. Any ideas?
I'm running Linux kernel 2.0.36 (RedHat 5.2) with Blackdown's JDK
1.1.7_v1a. The following little class demonstrates the problem...
import java.io.*;
class input
{
public static void main(String[] argv)
{
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
try {
while (true) {
String line = in.readLine();
if (line == null) break;
System.out.println(line);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
And here's a simple shell script...
#!/bin/sh
java -classpath $CLASSPATH input

I ran into this same problem. I too posted a note to the mailing list
but I did not hear back from anyone. The really odd part was that it
only seemed to happen when running with native threads. If I ran the
green threads version it worked just fine. Another strange thing that
seemed to happen with that native threads version is that reading
from System.in did not work when java was invoked from a shell script.

Hey, Just wanted to drop you a note. There is a computer show this weekend at the Radisson Hotel in Overland Park. If you are still looking for those parts, its a good place to find them. I think the hours are 10 to 3 on Sunday, but you might want to get there early you know how those things go quickly. Its off of I35 about 1/2 mile east on 87th street. Its $3.00 to get in but the saving more than makes up for that. Last time there were several dozen vendors and they always have giveaways, I know they give away $50.00 at 2pm during every show. It should be a good one. See ya there. dave

Re: 117a installation grief
Which installer are you using? Did you read the FAQ? Did you read the INSTALL docs? It's short, so it's easy to be fooled into just skimming, but there are some very important details in there. I'll bet you are using the Motif version. Forget that - get the regular version. Also, grab the X dev rpm from an ftp.redhat.com mirror and put that in too. Sounds like you don't have it installed, which will be a pain in the future. You'll prolly want the C/C++ gcc dev libraries too. I installed blackdown java as a newer than new newbie without a glitch. Read carefully and you should have zero problems...

Thanks, it was the permissions, but not because I was using root. I don't normally log in as root but it was necessary for tinkering with the javawrapper script. The permissions were fouled up for a very wierd reason - I had written the code prior to upgrading the system. The upgrade did not go smoothly and somehow my user id # got fouled up. The system didn't consider me the owner even though "I" was the original owner and wrote all the code. However, even so, shouldn't class files as opposed to source files normally be readable by anyone? That was not the case here. My class files seem to be readable only by owner and group, not everyone. > > > Michael Sinz -- Director of Research & Development, NextBus Inc. > mailto:[EMAIL PROTECTED] - http://www.nextbus.com > My place on the web ---> http://www.users.fast.net/~michael_sinz

The main advantage of running Java apps on the Linux platform is that you're not tying up a perfectly good computer on running Windows :-). Your latter question is an interesting one. The Java on Linux is very good, and Linux is a good enterprise platform. I'm also curious to know what sort of enterprise-level apps are exploiting Java on Linux -- is there more to enterprise Java than servlets? Nathan
java question
I realize that this is not the proper forum for this, but I consider this list pretty knowledgeable about java and I just toy around with it at the moment. My employer is working on an application that is deliverable on many platforms, from a standalone win32 platform to client-server versions served everywhere from NT to mulitple flavors of unix (Sun, HP, AIX, etc.) to AS400. The application is written in C and C++. One minor part of this application, for which I have become responsible, delivers a file of updated information to the users via the internet. Once a month, the administrator of the customer system would contact our web site and download the information. However the design is to do it from within our application, not from a browser (just press a button). The thought of programming this connection and the logic behind it (don't download file if already up to date, etc.) on all these platforms is a little daunting, and so tonight, it occurred to me that perhaps this part of the application - contacting the web site and ftping the file - might be doable as a java bean. Offhand, this seems like a great way to make use of the cross-platform capabilities of java. Performance is not an issue. The file is small. My questions are then, 1) are java virtual machines available on the full range of platforms mentioned above? 2) if customers do not have java installed, what runtime licensing issues are there? 3) How difficult and how possible is it to call java beans from C and C++ code on these platforms?
