Hi all,
I just installed the glibc verison of the blackdown JDK 1.1.6 and I am
getting this error when trying to complile a simple program using javac.

classpath problems?

[a]

Hi all 
Still having problems. My CLASSPATH is set to the needed directories as
well as classes.zip but I still keep getting these dang errors.

Can't find class test.class (the test program)
Unable to initialize threads: cannot find class java/lang/Thread

help!

Re: classpath problems?

[a]

Here is my CLASSPATH that is not working

CLASSPATH=.:/usr/local/jdk116_v5/lib/classes.zip:/usr/local/jdk116_v5/lib:/u
sr/local/jdk116_v5/lib/moreClasses:/usr/local/apache1.3.3/share/j-bin

Re: classpath problems?

This works:
javap -classpath $CLASSPATH java.lang.Object

This don't work: (my.class is in same directory)
javap -classpath $CLASSPATH my.class
Class 'my.class' not found

This don't work:
java -classpath $CLASSPATH my.class
Can't find class my.class

This works:
java -classpath $CLASSPATH java.lang.Object
In class java.lang.Object: void main(String argv[]) is not defined

Thanks Scot and everyone else. I was calling it with the *.class extension.
Without it it works.

Re: JDK1.1.6v4a can't find library libXp.so.6

[A . KLOS]

I have the same setup as Wim does (RedHat4.2) and encounter the same 
problems: can't load library libXp.so.6 .
Upgrading to a newer version of XFree86 should be easy with the RPM 
mechanism of RedHat. Unfortunately RedHat 4 is linked against libc5 and 
RedHat 5.x is linked against libc6 (a.k.a. glibc).
I am afraid that the only RPM of XFree86 3.3.2 I can find will be 
linked against glibc or is there anybody that knows of a  XFree86 3.3.2 
RPM linked against libc5?

There *IS* a plug-in port available for Linux. I've got one somewhere. 
Don't remember where I got it from and I didn't find the time to give 
it a try. I think it even has the name beta-version: Activator...

 I did try the windows version though, and that one worked once pretty good.
Nowadays, I can't use the plug-in anymore, since upgrading/uninstalling 
and installing of various versions of this product was too much for the

I needed CORBA support for Linux as well. At time I was not aware of 
any free Java ORB availbale so I did the following... I unzipped 
classes.zip from JDK1.2beta3
for win32 and picked out the stuff related to CORBA (something like 
org.omg.corba.*)
and re-zipped it as OMGCORBA.zip). I used this class archive 
successfully under Linux!!! I admit it is a bit of hacking, but it 
proves the portability of Java (at least of
the ORB implemented by JavaSoft).

Maybe it has something to do with class access modifiers. Is you main

an error on one and
not the other, but...

Indeed, you need to generate the java source code with the windows
JDK. Some other things....

You also will need to have a C/C++ compiler on Windows, since JavaIDL
use the preprocessor of any existing C/C++ compiler (however they recommend
MS VC++ 4.2 or higher I think :-(  )

I was not able to start the nameserver on Linux. I can't remember what 
the error message was, but it just didn't work.

I have used only the client part of the ORB from under Linux. What I

put those in a separate file e.g. OMGCORBA.zip.

However I could not get the nameserver to work under Linux. It said 
something like:
"Not supported under Linux".. if I remember correctly.
Additionally you still need a IDL compiler...

Maybe is http://www.ooc.com provides a good option like David Lucas

I completely agree with Steve's point of view. There are a lot of

P.S.: please let me know if it indeed has something to do with an underscore.

Which version of JDK do you use? Because JDK1.1.6 for Win32 has got a 
JIT and use that one by default (unless you explicitly disable the JIT 
with java -nojit...)
JDK1.1.6v2 hasn't got a JIT built in, but you could use one called TYA 
(v0.7: http://www.dragon1.net/software/tya/) and takes only 50K.

It improves the speed quite a bit (aprox. 3 times faster), but not as 
dramatically as the JIT that comes with JDK1.1.6 for Win32 (symantec JIT).

Furthermore TYA is not entirely stable yet, but is definitely worth to try!

You have to put your stuff in a JAR-file and sign that JAR-file using a

JDK1.1.x ships such a tool called javakey. javakey uses an alogorithm, 
called DSA, which is a public domain encryption algorithm.
Netscape however doesn't understand DSA, but only RSA instead, which is 
patented by RSA Inc.
Netscape delivers a free tool called SignTool (formerly known as 
Zigbert, I believe), which you can download somewhere from 
developer.netscape.com with which you should be able to sign your 
applets in a way the Netscape browser understand it.

The Internet Exploder is a totally different story, which I don't know

Java wrappers

[a . saha]

Hi there

I was wondering if there are any java wrapper libraries or sample
code available to access C exported functions.  I am not very 
familiar with this, as I have programmed all my life in C - but
basically what I would like to do is - if I have my routine in C to
access the kernel network stack and change certain parameters, 
I want my java application to be able to use this routine. So, as
I understand, I would need to write a wrapper which will enable 
the apps on top to call this in the form of a shared object library
or so.  

Any pointers on this is appreciated.

-Amlan.

Sun/Inprise/GPL Linux JDK

[a b]

Hi
   
I wonder what would happen if any of the Blackdown developers had put a GPL
license in any part of their code fixes?
   
How would that affect Sun's Community Source license?
   
Maybe GPL was a good idea after all?   Now we see what they mean by
protecting your rights to give away your software.
   
A well wisher.

I've only got libjava.so in /usr/lib/jdk1.1.6/lib/i686/green_threads.
It seems to me the reason should be in classes.zip and not
in libjava.so, what do you think? Without source code for the
java classes all those marvellous line numbers mean very
little.

It's exactly this program that first gave me this error

Could you confirm that JPEG images work for you? It seems
to me that JPEGImageDecoder.produceImage tries to call
the wrong external (readImage), whereas the JPEG library contains
only sun_awt_image_JPEGImageDecoder_readImage. I don't know enough
about the java innards to know how the function names are
cooked up, but should the error message not be something like
java.lang.UnsatisfiedLinkError: sun_awt_image_JPEGImageDecoder_reeadImage
and not just 'readImage'

Just grasping at straws.

Please review include/linux/posix_types.h, which explains that a
maximum of 1024 open files per process are supported, and that this

it seems to me that the __FD_SETSIZE could be increased without
problems, but YMMV.

Please don't forget to update the system-wide number of open files
and inodes by echoing the appropriate value to
/proc/sys/kernel/files-max and /proc/sys/kernel/inode-max
in your rc.d boot scripts.

PS. Maybe you might want to review the design decision to
have 2500 open sockets. IMESHO you'd be better off splitting
the application over several servers. BTW, Java is a speed-hog,
is there any good reason to use it for the server?

Re: Swing in JDK 1.2

[Scott A. Miller]

Agree, we should all respond to this.  In addition to forcing developers
to put classes in com.sun.java that shouldn't exist there, this will
prevent use of the "cross platform look and feel" that Sun promised Java
developers early on in the evolution of Swing.  IOW we will only be able
to use a Win L&F on Windows, Mac L&F on Mac, etc.  If it is the opinion
of Sun's legal staff that sanctioning this capability may place Sun in
jeopardy from litigation, let Sun put *loud* disclaimers and comments in
their material that use of a proprietary L&F without permission of the
"owner" may constitute infringement on intellectual property, but leave
the final decision to the developer!

Re: Socket connect timeout?

[A. Craig West]

I thought that the whole process blocked on blocking IO calls only in
the case of
System.in, due to the original implementation. I'm on thin ice here,
though. I was
under the impression that other blocking IO calls were written to use
non-blocking
OS primitives.

You forget the most important part (for a compilation machine) namely
the disk subsystem. Get a lot of memory (128Mb, or even 256Mb will
do fine, but more is better), and a couple of U2W (they're backwards
compatible with the UW ones and cost no more) on a dual Adaptec 
controller (Intel, Asus, Gigabyte, SuperMicro etc make nice boards
with integrated SCSI controllers). Get two PII-266 or PII-300
processors (they're really cheap now) instead of one PII-400.
I have a dual PII-266 (Intel Dakota, with 128Mb and SCSI disks
and I compile the Linux kernel in about 7 minutes, honest).

Don't get an IDE machine. In my experience, they're an order of
magnitude slower than a good SCSI box.

- A dual CPU motherboard, with built-in SCSI and 100Mb/s ethernet
from a reliable supplier (see above). Get one with the BX chipset
if possible (100Mhz bus), but even an LX based board (such as the
Intel Dakota, going cheap) should be ample.
- CPU: A PII-300 is more than competent enough.
- Not necessarily the fastest CPU (CPU speed is sexy, but hugely
overrated)
- A quality case with good cooling (if it's in a cupboard, stick
in a couple of additional fans, or one of these nifty disk 
coolers)
- A UPS (they're really cheap these days) does wonders for
reliability.
- Don't sacrifice to the bleeding edge.

Enjoy!

Two 4.5G Quantum UW drives, 7200rpm. I haven't timed the 
compilation with one CPU - I recompiled the kernel with
SMP support and haven't had one problem since.

If you mean "can I get the jdk-1.1.6 RPM file from the RedHat page and

I am doing it now.  However, jdk-1.1.6 does not come with the RedHat 5.1

Well JPassword has a method called getPassword() officially in the
Swing-1.1beta that I have. It may that Swing 1.0.{1,2,3} does not
properly support this method properly. Yes I had a deprecation if I remember
You may need to get the latest JFC zip from Sun. Oops!

Are sure that CLASSPATH does not refers to another older JFC.

Have you got also the latest JDK 1.1.6v3 or above, but this may not help
you.

multicast via slip

[Gwobaw A. Wu]

Hi,

Does anyone know whether linux java allow multicast via slip?
Currently, I am running jdk 1.1.6v1 and have a modem (28.8k) running slip.
TCP/IP runs ok but it gave me core dump when I tried to join multicast
group:
   java.net.SocketException: Cannot assign requested address
at java.net.MulticastSocket.joinGroup(MulticastSocket.java:153)
at Client.joinMulticast(Client.java:29)
at Client.run(Client.java:39)

The code runs fine on a SUN solaris machine and on a linux box with
ethernet connection.
I have fixed ip address although I am running slip over modem.

Thanks.

javah problem in package

[Gwobaw A. Wu]

Hi,
I notice that javah has a problem in generating stub include file
within a package.  Without package, javah is able to generate stub include 
( xxx.h ) file.  Here is the error message :

javah Time
Time: no such class.

CLASSPATH is set correctly since javah works without package in the
source.

I also notice that jdk115 on solaris has the same problem.
The only version I found that works is jdk113 on solaris.  jdk115,
jdk116v1 jdk116v4 on linux do not work.

Is this bug will be fixed in the near future?
Please let me know.

BTW, On SUN's jdk116 download page, it mentions that jdk116v4 fixes javah
problem.  I don't know if this is the same problem that I have.
I have not tried the new version yet.

java.lang.UnsatisfiedLinkError: readImage

[Stefaan A Eeckels]

Hi List,

I've just subscribed (and just installed jdk1.1.6-v1 on
my Linux 2.0.34 S.u.S.E based box, and I get the following
error when running some of the demo programs:

java.lang.UnsatisfiedLinkError: readImage

I also get this with tya's Iview demo package.

Sorry if this is a FAQ, but www.mail-archive.com
seems to be down.

Thanks a lot,

Hi List,

Sorry to follow up on my own message, but it was late
yesterday night, and I should have added the complete
error message.

Here it is:

Any idea what I forgot to install?  (1.1.5v7 gives the same

Thanks a million,

Re: java.lang.UnsatisfiedLinkError: readImage

[Stefaan A Eeckels]

Hi List,

I did some more tests, and I have the following frustrating
results:
- JDK1.1.3 on Linux 2.0.34 (heavily updated Slackware 95) gives
no problems (this is an older 486/66 machine too slow to do
serious java work) 
- I exported the JDK directory from this machine, mounted it
on the PentiumII (SuSE 5.1 core and kernel 2.0.34), and made
a symbolic link (/usr/lib/java -> /net/opt/java/jdk1.1.3).
I recompiled tya0.7, and it properly recognises that version
of the JDK. Now the demo program (Iview)doesn't run. 

Conclusion - it's something on the PII box that causes the
link problem. The only difference is that on the old box,
the version of ld.so is 1.9.5, whereas it is 1.9.6 on the
new machine. 

Any clues - this really puzzles me no end, but as I have
other work to do, I'll let is simmer for a while and see
if I can come up with something.

Thanks a lot for listening,

Stefaan

I only got this suggestion after I sent of my previous mail
(dialup obliges), but I can report now that this was indeed
the problem. There was a symlink to libjpeg.so.6.0.1 called
libjpeg.so on the PII, and this confused the loader. What I
don't get is why setting LD_LIBRARY_PATH to the java library
directory had no effect. Re-arranging ld.so.conf didn't work
either. 

Oh well, the vagaries of shared libraries ;-)

Many thanks, Jürgen and Albrecht. I can go back to something
more productive now.

Need a Java/Linux RedHat 5.0 configuration where getLocalHost works

[John A. Zinky]

We have not been able to find a configuration of Linux Red Hat 5.0 and
jdk 1.1.x that works for the following one line test program.

public class TestGetLocalHost {
  public static void main(String[] args) {
try {
  System.out.println(java.net.InetAddress.getLocalHost());
} catch (Exception e) { e.printStackTrace(); }
  }}

The Test program prints the IP address of local host 
(A necessary function for servers that need to publish their location)

On Solaris,NT, and  Red Hat 4.0/jdk1.1.3 this works: e.g:
   guava.bbn.com/171.78.82.34
On Linux Red Hat 5.0 jdk1.1.5 this returns the loopback address: e.g:
   localhost/127.0.0.1

We have traced the problem in to the C routines for native platform
on Line 298 in .../jdk1.1.5/src/java/net/InetAddress.java
localHost.hostName = impl.getLocalHostName();
System.out.println("local host name: " + localHost.hostName);

On linux: local host name: localhost
On Solaris:   local host name: guava.bbn.com

 Questions *
1) Does anyone have a Linux RedHat 5.0 configuration where this program works?

a) jdk1.1.3 does not work under RedHat 5.0 because it uses libc and not glibc
   Is there a way to shimmy in libc just for this one java executable?

b) We have tried several version of jdk1.1.5 and jdk1.1.6, 
   all of which we had a hard time installing.

c) How about a statically linked version of jdk1.1.x?

2) Could this be a configuration error in the linux host?

3) Could we hack the C source for impl.getLocalHostName?
 a) Where is the source code?
 b) Where is the Make?

4) Could this be a security feature?
 The news groups has lots of chatter on why getLocalHosts should not
 give the IP address IN THE CASE OF APPLETS.
 But this case, we have a SERVER, so it needs to get it's own address.

thanks
zinky

Re: which is the best CORBA/Java implementation?

[Douglas A. Seifert]

>   Any chance to find something like this? BTW is anyone here using CORBA in
>   conjunction with java?

Hello,

We have been able to get the JDK1.2beta CORBA implementation to work on
our Linux box.  All we did was unjar the jdk1.2beta classes.zip and then
jar up all the org/omg stuff into a new archive.  Put the new archive in
your $CLASSPATH and you've got a "free" CORBA implementation.  So far,
we've experienced no problems with it; it even runs fine using the
shuJIT just-in-time compiler.  We did have problems using it with TYA,
however :(

If you want, I can email you our "corba.jar" file.  It is based on the
org/omg stuff extracted from a jdk1.2beta4 classes.zip file for Windows
NT.  But, as I've said, it works fine for us on Linux.  True "write
once, run anywhere" in action!

Yes, no help for this.  We have had to run idltojava on a Solaris box
we have access to, then ftp over the results.

Try this:

// Start up a collocated NameServer.
class NameServerThread extends Thread {
  private String [] m_args;
  public NameServerThread(String [] f_args) throws Exception {
m_args = f_args;
start();
  }
  public void run() {
 com.sun.CosNaming.TransientNameServer.main(m_args);
  }
}
NameServerThread nst = new NameServerThread(argv);

TransientNameServer wants "-ORBInitialPort " as initialization args.

You can stick this is in a stand alone app or in with your server code.  If
you put it in with your server code, make sure that you put
Thread.currentThread().yield(); right after starting the NameServerThread so
it has a chance to get going before you try connecting to it.

Hi,

My friend told that Javac - compiler is written java language.

How it is possible to write first version of javac compiler

in java before java language came ?

I don't see why it would have any bearing on the DoJ's
case vs. Microsoft (which is about business practices,
not technology) or Sun's case vs. Microsoft (which is about
not respecting license terms). Cringely suggests that MS
acquiring a license to a patent (delivered 4 years after the filing,
so it seems) would retroactively prove that they have not
behaved in an anti-competitive way. 

If Cringely really believes that 'executable content' is at the
foundation of Java, he needs his head read. 

BTW, the Eolas web site (www.eolas.com) uses Java in their
'zMap' technology.

Re: [FYI] Java violates US patent?

[Stefaan A Eeckels]

Sorry for continuing this fairly off-topic thread, but IMHO it
has some relevance to the use of Java on Linux (if even a little :-)

The full text of the patent can be accessed under the following
URL:

http://164.195.100.11/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=/n
etahtml/srchnum.htm&r=1&f=G&l=50&s1='5,838,906'.WKU.&OS=PN/5,838,906&RS=PN/5,838
,906

it's real easy to locate on the PTO's server (search for patent #
5 838 906).

The abstract contains the following sentence:

"After launching the program object, the user is able to interact with the
object as the invention provides for ongoing interprocess communication between
the application object (program) and the browser program."

This seems to indicate that the invention requires two programs
to interact (the browser and the program launched as a result
of the user interaction with the browser, either on the local,
or one or more remote computers. IMVHO, this does *not* describe
Java applets, as there is *no* separate program that runs when
a Java applet executes (it runs as part of the browser program,
and fully resides within the browser's address space). 

As the law is all about nit-picking, I've picked mine, and
IMHO the patent does not describe plug-ins (which are a dynamic
extension of a the browser), but *external* programs used to
control a browser through IPC. No two programs, no IPC, no
patent.

Any comments?

Thanks for the information, Ray (and congrats on the patent(s) :-)

I did read through the claims, and the most used word is
'said'. Am I glad the Bard was not a lawyer.

Claim 1 (the most generic one) specifically mentions a client 
running a browser, displaying a hypermedia document stored on 
a server, that also contains information to enable the machine 
running the browser to locate and execute a program external
to the original document for the purpose of controlling information 
presented by the browser.

Claim 2 extends claim 1 by stating that the external program
(application) can be controlled through IPC from the browser.

Claim 3 adds continued control of the application even after
it has been launched.

Claim 4 adds indirection by having the browser issue commands
to the server, which sends data to the external program for the
purpose of controlling it. The 'instructions' required to interpret
the commands are located on the server. 

Claim 5 stipulates that these instructions can also reside on the
client. 

Claims 6-10 are essentially the same as 1-5, but specifically talk
about 'program product', and seem to be the patenteze required to
turn the whole shebang into a 'product' and not an idea (IMHO).

IANAL, but it seems clear to me that the patent doesn't describe
Java as a portable language. It doesn't deal with languages at all.
It also specifically requires a system comprising a client, a server
and a network, a browser, and an *external* application. A Java
applet running *inside* a browser's address space is not an external
application. 

IMHO, Cringely made an ass of himself.

How to send e-mail ?

[Ramesh Babu A.]

Hi,
I want to send e-mail from my java program.

for that i opend socket on 25 (SMTP) port, and sent mail
by executing HELP, MAIL FROM:, RCPT TO:, DATA.
This is working fine only in the internal network. But if
try send to hotamil/rocketmail they are not allowing to
bind on that port.
(   new Socket(domainName, 25);   )

Pls tell, how to send mail from my java program.
also i don't want to send mail thru' executing sendmail
utility (exec()) from my Linux m/c. It should work
also in solaris/Linux/Win 95 etc.

Hi,
I have a couple of doubts in java. Is it a right place to ask this

Is java pass arguments to functions PassByValue / PassByReference
other than primitive datatypes ?
If PassByRefernce this reference is equivalent to C++ Referencee ?
pls see the follwoing eg.

class PassBy {

  PassBy() {

String[] arr = new String[] {"Hi"};
System.out.println("B4 calling fn, " + arr[0]);
Call(arr);
System.out.println("After calling fn, " + arr[0]);

Uhh.  That's motif.  You need a static build, which should be in there,
so that you don't need libXm.so.2.  Otherwise you'll have to buy motif.
 You can try lesstif, but it's not motif 2.0 compatible.  It works as

Hi,

I need one suggestion from u people.
I have GUI wriiten in JDK1.1.6, Linux RH4.1.
Now i want to communicate with my native code(C++).
shall I use JDK1.0 native method or JDK1.1.X native methods.
Why I am asking this question, I have tried with JDK1.0 
native interface, but it is giving lot of errors like
thread dumps, monoitor dump, SIGENV. 
How to reslove SIGENV prob?
so pls suggest which one is better ?
and in JDK1.1.X JNI - what is the advantage ?

CLASSPATH variable too large ?

[Ken A Redergard]

I have a large amount of .jar files in the library directory, and that
leads to a very large CLASSPATH variable. 

The seems that java (java version "1.1.7") won't accept the
classpath when it reaches a certain amount of characters. I currently have
331 characters in the path, and when I run a .class file java reports that
the class can't be found. If I set the classpath to a much smaller amount
of characters the program runs...

Any suggestions on how to solve this problem (except from decompressing
all the .jar files in the library directory) ?

With regards,

createImage/swing bug

[David A. Green]

First, let me express my gratitude and congratulations to the blackdown
porting team.  Great job!

Second, I have run into a bug/issue regarding the createImage(int, int)
function in java.awt.component.  I call this function to create an
off-screen image to be used for double-buffering.  I get the following
exception:

Exception occurred during event dispatching:
java.lang.IllegalArgumentException: Raster IntegerInterleavedRaster:
width = 300 height = 200 #Bands = 3 #DataElements 1 xOff = 0 yOff = 0
dataOffset[0] 0 is incompatible with ColorModel DirectColorModel:

at java.awt.EventDispatchThread.run(Compiled Code)

I also get the following exception whenever I try to use a swing
component.  This particular one was from the SampleTree demo app
included in the jdk1.2:

Error loading L&F: java.lang.IllegalArgumentException: Raster
IntegerInterleavedRaster: width = 64 height = 64 #Bands = 3
#DataElements 1 xOff = 0 yOff = 0 dataOffset[0] 0 is incompatible with

All of the code that generates these exceptions works just fine using
java 1.1 or java 1.2 on both the Win32 and Solaris versions of the jdk.
I am running Debian 2.0, with some libraries upgraded to 2.1 (slink).
My only thought is that I am running in 32bpp mode in X windows and that
may be causing problems with the offscreen images being incompatible
with the DirectColorModel used to decode the pixels (which assumes 24bpp
color and 8b of alpha).  Also, despite the exceptions, the image still
loads.  This, however, is not true for the swing exception, which kills
whichever thread is creating the swing component.  I have tried in 24bpp
mode, but I just get a jvm crash whenever it loads the image.  I have
attached my test program which creates a simple double-buffered panel
with an image painted on it.  Does anyone have any thoughts?  Is this a
bug in the java classes or in the jvm?  Should I report it to sun?
Thanks.

Re: createImage/swing bug

[David A. Green]

OK, switching to 16bpp fixed the problem.  The question remains, is this a
Linux-Java bug or a Sun-Java bug?  As in, should I report it to the blackdown
team or to Sun, or have you already reported it?  If the same problem occurs
displaying to a Linux box from a Solaris machine, then it seems that it is a
Sun bug, but the crashing under 24bpp mode sounds more like a Linux problem.
What do you think?

Bug in JDK 1.1.6

[Jonathan A. LaCour]

Hey, I am a developer at VertiSoft Inc, and I seem to have discovered a
bug in your version of the linux JDK.  The bug appears to be in the AWT
listbox component.  I am attaching the classes/source for a JDBC based
application in a zip file.  You will need to get the SolidDriver for
java from www.solidtech.com and put it into your CLASSPATH.  The bug is
as follows:  run the application by typing java GroupMaint.  Then type
LAC into the textfield at the top of the application.  Press the "Faxnet
Search button".   Then double click on the name that appears in the
listbox just below the textfield (this is my name).  Following this,
attempt to add TESTGROUP1 and the other groups by selecting it in the
listbox on the left and then pressing the > button.  This *should* add
the group to the box on the right and remove it from the one on the
left.   This works on the windows JDK from Sun.  This program is *far*
from completion, so don't expect any other fuctions to work.  I hope
I am of help to you.

also, you will need to be connected to the internet for this to work!

Re: Socket connect timeout?

[A. Craig West]

This thread isn't exactly topical to Java-Linux, but I'll throw in my 2
bits to bring
it some closure, I hope.
It is true that Socket.setSoTimeout(int timeout) causes reads to throw
an
InterruptedIOException, but the problem he is trying to solve is that it
does NOT
cause connects to throw an exception, or timeout in any other way. It
will timeout
eventually, depending on the OS, but there is no control over it.
When I need to do this, I use another thread to check the timeout, and
if it has
expired, I close the Socket. That tends to work to unblock the thread
doing the connect.
Actually, there is an On-Topic question for you... Does closing the
Socket on the Linux
JDK port cause the connect statement to throw an Exception of some kind?
I've never
tried it in Linux...

Re: Socket connect timeout?

[A. Craig West]

You are, of course, correct about this. I seem to have confused myself
in here
somewhere. I must have done something like this in C code or something.
Now THAT's
off-topic :-) I'm sure this close trick applied to something I've done
in Java, but
I wish I could remember what.
As far as actually solving your problem goes, I believe that
Thread.interrupt will
actually be useful for this kind of thing in 1.2. Of course, first we
need a 1.2 port
for Linux...

Question concerning the 1.2 port

[Samuel A Mullen]

Blackdowners,

I've been checking out the site on a pretty regular basis to see if 1.2 is ready
for the big time and I just saw that the row for i386 is all green.  Does that
mean that it's out of the beta stages and ready???

If it's not ready yet, is there an expected date?

Thanks,
Samuel Mullen

JDK 1.2 pre-v1 problem

[Alexei A. Petrenko]

Hi

I have Slackware Linux 3.5 and tries to install jdk1.2 pre-v1.
First of all (when i've just unzip it) it says that it could not find some file.
I investigate that it wants some libs such as linc.so.6 and ld-linux.so.2 which there
is not on my system.
I've found them in glibc-2.0.6. When i've install them i got "Segmentation fault"
error. In README.linux you says that 2.0 is not very good and 2.1 is much better but
2.1 is deleted from gnu.org. So I've set LD_BIND_NOW environment variable (as
README.linux says) but no changes. I've tried both green and native threads.
Can you help with it?

SY, Alexei

Re: Red Hat: no GUI due to Debian lib refs

[David A. Guthrie]

Please the read the faq.  This is all covered in that.  You do have libc6.0,
its glibc2.0.7 on redhat.

Hello, I was wondering whether I could have a diff for the linux port
of the JDK1.2 against the Solaris reference platform?

Thanks.
