Java 3D in Linux Redhat 9

I downloaded Java3D 1.3.3 for Linux from ftp://ftp.tux.org/pub/java/java3d/1.3.1/
in the i386 area.
I am running jdk 1.5.0_02. on linux Redhat 9.0.
The code appears to install correctly.
When I compile and run the HelloJava3Da demo I get the following error, as Jery reported
last month;
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: sun/awt/DrawingSurface
Does the fact that no one responded to Jery's original post indicate that Java 3D does not
run with the relatively standard "DrawingSurface" class in linux?
Perhaps I was mistaken that Java, and Java projects, such as Java 3D, were supposed to be platform independent?
This example runs fine in WIndows XP using the same versions for Windows.
Does something need repair in the linux versions?

Running a java service on linux (Redhat)

I can create a basic script to run my java service, I can stop, and restart it from the command line when logged in. I have installed the script as a service. However, when I reboot, the service will not start. I have set it to be the very last thing to start on boot-up. I'm thinking it may have something to do with the fact that when I run a java program, it does not bring me back to the command line, it just 'hangs' until it is completed, and this particular java program will obviously hang indefinitely as it is a service.
Any help would be GREATLY appreciated.
Thanks,
PAUL.

Why not start it in the background? (a trailing ampersand)

Java not detected in redhat 5 linux firefox

I have installed the latest java 1.6_24 version using rpm on linux redhat machine. "java -version" works OK, I have the link:
libjavaplugin_oji.so -> /usr/java/jre1.6.0_24/plugin/i386/ns7/libjavaplugin_oji.so
Also:
/usr/bin/java -> /etc/alternatives/java
/etc/alternatives/java -> /usr/java/jre1.6.0_24/bin/java
In the past install (java 1.4) there where also some references to "jvm" but these don't exist in 1.6 version.
Must be something else missing..

libjavaplugin_oji.so is the old classic Java plugin. For Firefox 3.6.x you need the Next Generation Java plugin (libnpjp2.so)

Problem with java, ASCII and Linux

Hi Friends,
I has a Linux RedHat 9.0 with a jre1.5.0_04 (rpm package of Sun).
I has a problem with ASCII , for example :
import java.io.*;
public class HolaMundo
public static void main (String[] args)
System.out.println("Hol� M�ndo");
this programs runs ok on my windows jdk so it prints "Hol� M�ndo", but when i run the same HolaMundo.class program on my linux redhat it prints "Hol�� M��ndo"
I think the problem is with the ASCII table that uses the linux version of jre, but i dont know how to solve this problem. I need a Spanish-European ASCII table on my application but i think it is working with a US-ASCII table.
Then i has installed a kaffe 1.0 (rpm) java machie on this linux and this solve the problem but i has another problems of compatibility with this old version of java kaffe.
Do you know whats happening?
Thanks in advance.

The problem doesn't have to do anything with Java or Linux as far as i can see. It's more likely a problem with Windows XP and IE. Be assured that normally downloading the Linux JDK in windows is not a problem.

Printing a document to a specific printer - Linux RedHat

Is it possible to print a document to a particular printer with the jdk1.4 in Linux RedHat? I am trying to select a printer with the following program (where args[0] is the name of the printer) but even though it seems that the program selects the right printer service the output allways goes to the default printer of the server.
public class PrintFile {
public static void main(String args[]) {
          String printername = args[0];
          String filename = args[1];
          if (printername != null) {
          if (filename != null) {
          try {
          javax.print.PrintService myprintservice = null;
          //Document flavor
          javax.print.DocFlavor flavor = javax.print.DocFlavor.INPUT_STREAM.POSTSCRIPT;
          //Print service for
          javax.print.attribute.PrintRequestAttributeSet aset = new javax.print.attribute.HashPrintRequestAttributeSet();
          aset.add(javax.print.attribute.standard.MediaSizeName.NA_LETTER);
          //Creating the Print Service
          javax.print.PrintService[] service = javax.print.PrintServiceLookup.lookupPrintServices(flavor,aset);
          if (service.length > 0) {
for(int i=0;i<service.length;i++) {
if (service.getName().equals(printername)) {
myprintservice = service[i];
break;
          if (myprintservice != null) {
          java.io.FileInputStream file = new java.io.FileInputStream(filename);
          javax.print.Doc doc = new javax.print.SimpleDoc(file ,flavor ,null);
          //Send the document to the printer
          javax.print.DocPrintJob pj = myprintservice.createPrintJob();
System.out.println("Printing to: " + pj.getPrintService().getName());
          pj.print(doc, null);
          file.close();
System.exit(0);
} catch(Exception e) {System.out.println(e.toString());}
Is this a bug or am I missing something?

Yes, I've got the same problem, too. First I get all the print services using PrintServiceLookup.lookupPrintServices(DocFlavor flavor, AttributeSet attributes)
Once I have the array of PrintService object I get the one that I'm looking for:
for (int i=0; i<services.length; i++) {
PrintService ps = services;
if (ps.getName().equalsIgnoreCase(myPrinterName)) {
myService = ps[i];
break;
But when I try to print through the object "myService" the printing always goes to the same printer!!!

Bash shell does not recognise 'java', 'javac' commands (Linux command line)

i' ve used javac and java compile & execute commands to build the same application on the DOS command line with Windows - no problem.
But when I try to compile the same file on the command line under Linux Redhat (7.1) using Bash shell i get <bash: javac: command not found> and <bash: java: command not found>.
In both cases I'm using j2sdk1.4.2 downloaded from java.sun.com for Windows & Linux respectively.
I make sure I have both the javac and the file I want to compile in the same directory ../j2sdk1.4.2/bin for both the Windows and the Linux applications.
Is there something I need to do to get bash to recognise javac, java etc? Is there a different setup procedure?
Any angles on this are much appreciated ..

Have you tried these correctly..
Set the CLASSPATH environment variable to include whichever directories you like, eg (on bash) type:
export CLASSPATH=$CLASSPATH:.:<your java dirs>
To make java easier to run, put the directory in which it is installed into your path:
export JAVA_HOME=<where you installed java>
Then do
export PATH=$PATH:$JAVA_HOME/bin
verify it has worked by simply typing
java
You can put all of these commands into the .*rc file for your shell, so that they are executed every time you open the shell. So if you are using bash you can put them into ~/.bashrc
Read up setting the PATH and CLASSPATH for more info.
This shall resolve the issue .

Does printing in Linux RedHat requires CUPS?

Does the jdk1.4 Printing API require CUPS to run in Linux RedHat? I installed the JDK and programs run well but I cannot direct the printing to a particular prnter. The printing allways goes to the default printer. I ran the examples in Print2DPrinterJob.java (code at the end of this posting) and I find that the windows to select the printers appear, I select the printer to output the image, but the printout allways goes to the default printer regardless of the printer selected.
Since the java Printing API requires the IPP and since LPR is not based in this protocol, I was wondering if I must install CUPS in the server in order to use the printing API

i have experienced the same problem as you - inability to print to a particular printer on linux. this appears to be a bug - if you look closely at what is happening, you get the following exception thrown when you try to print to any printer other than the default one (however, by default it will just recover and print to the default printer so you won't see this exception unless you force it by trying to do a print service lookup with no attributes set). I have not had any luck gettign around this. CUPS does not help either - i have installed CUPS and still see this behavior. Let me know if you have found a workaround.

OC4J on Linux RedHat 8.0

Hi I want to know whether the OC4J which we use on Win2k is the same for Linux RedHat 8 or do we have to download a diff version?? If so where can I find that?
Or how to install OC4J on Linux RedHat8
Thanx
Kulkarni

I just unzipped oc4j_extended.zip into /usr/local/ and then started it like:
cd /usr/local/j2ee/home
$JAVA_HOME/bin/java -jar oc4j.jar &
Then exited my shell (which bash lets me do)

Java running under linux with crontab

I'm having a problem:
i want to run a java program under linux with crontab.
my classes are in a directory and aren't in a package. i run em by invoking ./start which is a small script that i wrote. The script is in the same dir as the classes and invokes java by "java Main >>logjava.txt " but this doesn't seem to work all i get is an empty logfile
i need to run the program every day at 0800 so i inserted the following in crontab:
0 8 * 1-5 /var/"path"/start > logjava (where path is the path to the classes dir)
if i run the cmdline from anywhere on the prompt i get the result i want. I think it's because the cron runs it from the root dir thus making java unable to find the classes
Any suggestions would be welcome. or can some1 tell me how to make linux executables from the java (i usually use jsmooth for the windows exe)

You can execute several commands in the process started by cron. You separate them using semicolons.
Have you tried a cron entry like this:
0 8 * 1-5 cd /var/"path";pwd;echo $PATH; ./start > logjavaOr, you may need to make sure the process started by cron gets the same environment as your interactive shells do, by explicitly loading your setup or .login scripts:
0 8 * 1-5 . $HOME/.setup;cd /var/"path";pwd;echo $PATH; ./start > logjava
