Java and 3D.

[Karthik Vishwanath]

Hi All,
I need to use some extensive 3d-stuff in a java app that i plan to
write. Do any tools exist that would enable me to use a 3d package as
OpenGl along with java?

Thanks,
Karthik.

well, what is wrong in downloading binary files as binary files ??? :-o. But
remember that you need bzip2 to unpack these files. bzip2 should be in your

Mehrdad,

if you have slackware 3.3, you may need the libc5 version of jdk. when i
had slackware 3.4, it did not have glibc or bunzip2, Unless you have
installed these yourself, you will need the libc5 and tar.gz version such
as -

ftp://ce.usu.edu/pub/mirror/linux/JDK/JDK-1.1.7/i386/libc5/v1a/jdk_1.1.7-v1a-libc5-x86.tar.gz

I see i also need to upgrade, current slackware is 3.6.0 ...

Re: RMI binding bug

[Douglas T. Brown]

Thank you all for your help on this.

I seem to have it working now.  There were two issues which I'll try to make
explicitly clear for the mail list archive and future reference:

1)  The correct syntax for the first argument string for rebind is:
"rmi://host/name", whereas I had only "//host/name".

2)  More interesting is that localhost does not work.  Thus,
"rmi//127.0.0.1/HelloServer" does not work, nor does
"rmi//localhost/HelloServer".

I solved this second problem by putting my machine IP, nickname and complete
hostname in /etc/hosts.  Thus,
"rmi//hostname/HelloServer" works fine, as does
"rmi//xxx.xxx.x.2/HelloServer".

I say 'works fine', by which I mean that naming binds the object without
complaint.  I don't have it actually doing anything, yet, but I naively don't
anticipate any problems.

Runtime.exec ()

[Marius Schamschula]

Hi there,

I am having trouble getting Runtime.exec () to do anything (yes I do send
the desired command as an argument...e.g. "/bin/ls /home/someusr/dir >
/home/someusr/test"). I've tested my code on both a mkLinux (DR2.1u5) and
Debian Linux machine running various flavors of JDK 1.1.x. I'm trying to use
Java to directly invoke various shell scripts. I do a waitFor () for the
process to terminate, check the InputStream and ErrorStream. The streams are
empty...

Any hints?

TIA

Re: Runtime.exec ()

[Mark Hofmann]

Hi,

I tried the same thing some time ago.
The problem is, exec works, for example if you try exec("ls") you wont get
problems. However, running anything as a command that has a
redirection of out-/ input in it fails.

I don't know why, but that's what I experienced.

Anybody knows why ???

You need a shell if you want to use '>':

Process p = Runtime.getRuntime().exec(new String[] {
"/bin/sh", "-c", 
"/bin/ls /home/someusr/dir > /home/someusr/test"});

.java_wrapper is a shell script.  setuid or setgid on a shell script may or
may not work depending on which shell you use and whether it is setuid to
root and knows how to manage its effective uid based on the protections of
the shell scripts it is executing.

[Bernd Kreimeier]

I had one problem on RedHat 5.1, had to take out
of the LD path a libzip available on the system
to allow for use of the one that comes with the
JDK, else you get linker errors:

Creating Java VM...
/opt/local/lib/libzip.so: undefined symbol: jmalloc (libzip.so)
Unable to initialize threads: cannot find class java/lang/Thread

Wonder whether this jmalloc is supposed to be in libzip.

Also, it asks you to set LD_BIND_NOW in your environment.
Nothing in the README, though.
 
Once that's done, this JDK now passes the basic invocation
test program. However, just as the Blackdown JDK did, 
OG JDK is still unable to survive a test program (my 
"inload") which loads the libjava.so with dlopen() first, 
and retrieves the invocation calls with dlsym(). Test 
app hangs. An app linked with -ljava but also against
-ldl hangs, too, when dlopen() is used to load yet another,
unrelated DLL.

Close, but no cigar. However, if you got Invocation and
no libdl.so involved, you might be fine:
   www.gr.opengroup.org,
and they were moving web/ftp sites, so you might have to
dig.

No. The answer is simple: for security reasons, the suid feature is *DISABLED*
if the file is a shell script. suid only works for applications

Re: Java and 3D.

[wbogardt]

More importantly is there possibly any group that plans on going to work
on porting Java 3D API to Linux?  I understand that the Java 3D API is
layered on top of and makes some calls to the lower level OpenGL, Direct3D
APIs, which are tied to certain hardware.
If you are looking for a more immediate solution to 3D stuff  to write
into your applets or application try  http://www.inworldvr.com/ they
appear to have a pretty good Java 3d API, which is written in 100% Java,
and works on Java 1.0 and 1.1.

Are you sure?  (note that you are missing the ":" character in the two

CLASSPATH var.

[Karthik Vishwanath]

Hi all,
The java... classes exist as a classes.zip file in
~/jdk-1.1.6/lib.  Also, the README.linux says that there is no need to set
CLASSPATH. 
If i need to use 3rd party packages present as .class files in a
dir such as ~/3rdparty//utils/classes/* how must i modify my CLASSPATH
var?

Thanks,

jdk_1.1.7-v1a-glibc-x86-native.tar.gz

We have a jni app that needs them.  Are they unchanged from 1.1.6 or

The native threads jdk is no stand-alone package, it's an

jdk_1.1.7-v1a-glibc-x86-native.tar.gz contains all include

Re: Linux + java + oracle

[Robert P. Biuk-Aghai]

Hi,

I have a similar setup (Linux 2 glibc, JDK 1.1.6, Oracle 8) and for me
it works fine, however in *applications*. I tried running the same
stuff in an applet, and although the classes111.zip file from Oracle
was in my browser's classpath, I would get the same or a similar
exception as you (don't remember clearly). Don't know why. As I
remember, I was able to run it in the appletviewer, so it might be a
Netscape issue (was using 4.06 at the time).

So if you have an application you should have no problems. Make sure
that you load the Oracle driver using a statement like this:

   Class.forName("oracle.jdbc.driver.OracleDriver");

Robert.

Simply that redirection is part of the shell, not part of the OS.  You
must invoke a shell to see that behavior.

You need to use jdk_1.1.7-v1a-glibc-x86.tar.gz along with the
native threads package.  The native threads package is just an
"add-on" to the "traditional" JDK.  (No need to download the

Re: RMI binding bug

[Douglas T. Brown]

You are correct to pick up the typos in my note.  The syntax
that I got to bind was in fact "rmi//... rather than "rmi:// ...

As I have since read various sources, I have found the syntax for the argument of
bind and rebind variably as:
("rmi://host/name", obj) or ("//host/name", obj).

Further experimentation has shown that ANY of the following forms execute
without throwing an exception:
("rmi://host/name", obj), or
("//host/name", obj), or even
("rmi//host/name", obj) without the ':'

I have found that 'localhost' or '127.0.0.1' will NOT work for 'host' in the
above forms, whereas the IP address for the server or it's nickname from
/etc/hosts will work fine as the 'host' element.  This all seems odd to me, I
must admit.  I must also admit I have yet to get lookup() to work on an applet
downloaded from the server.  If you have any insight into this I would be glad
to hear it!  I suspect I'm missing something obvious here.

Here's the code that executes the rebind:

import java.rmi.*;
import java.rmi.server.*;
import java.net.*;

public class HelloImpl extends UnicastRemoteObject implements HelloInt {

public String name;

public HelloImpl (String s) throws RemoteException {
super();
name = s;
}

public String sayHello() throws RemoteException {
return "Hello World!";
}

public static void main (String args []) {

System.setSecurityManager (new RMISecurityManager());

try {
HelloImpl obj = new HelloImpl ("HelloServer");
System.out.println ("Attempting to rebind . . .");
Naming.rebind ("rmi://xxx.xxx.x.x/HelloServer", obj);
System.out.println ("Hello Server bound . . .");
}
catch (RemoteException re) {
System.out.println ("RemoteException in HelloImpl.main:  " + 
re.getMessage());
re.printStackTrace();
}
catch (MalformedURLException e) {
System.out.println ("MalformedURLException in HelloImpl.main:  
" + e.getMessage());
e.printStackTrace();
}

}
}

This produces the "Attempting to rebind . . ." and "Hello Server bound . . ."
messages on the console as one would expect.
