JVM Size Limitations on Linux x86

2002-02-12 Thread Eric

I am depserately trying to get a single JVM to grow beyond the 2GB
size limit that I've hit.  I've tried both the IBM and Sun JVM's but
without any luck.  They both use mmap() to allocate memory, so there
isn't a way to drop in a better memory allocation ssytem such as the
"hoard" malloc().

My Linux configuration is:  Debian woody with a 2.4.17 kernel on a
Compaq Proliant 6500 with 4 Xeon 500's and 4GB of RAM along with about
800MB of swap.

I have tried the latest IBM 1.3.1, blackdown 1.3.1, and Sun 1.4
releases.  The problems with the Sun and blackdown JVM is as
http://developer.java.sun.com/developer/bugParade/bugs/4401509.html
puts it...the call to mmap is just plain over the linux x86 limit.
However, the IBM one is more mysterious...it seems to be just not
mmaping the right spot; the last mmap just hangs (and it's not trying
to mmap more than the limit)...it just doesn't mmap a whole gigabyte
of process address space from the end of its binary at 0x0804d000 to
0x400.

Does anyone have any idea how to fix this?  Would it be a big job to
fix it in the JVM?

Thanks,
eric.

Re: JVM Size Limitations on Linux x86

2002-02-12 Thread Eric

Ahh...this may be a solution.  It looks like I could build it to not
do mmap()s, but do malloc()s instead by using -DUSE_MALLOC (and maybe
even link it against hoard to have a really nice malloc)

However, it appears to be a total pain to get this thing to compile...
I have no idea where a JDK with libjvm_g.so comes from and OPEN_MAX
wasn't defined in some file and my yacc didn't like line 125 of
parser.y and signals_md.o has a bunch of unresolved symbols that
should be in threads_md.o 

Seems like if I actually reverted to the version of GCC they recommend
it might fix some of these problems, but I don't think all.  Does
anyone actually compile this thing?  :)  Someone want to help me with
getting one that has -DUSE_MALLOC?

VB and Access == Java and ????

1998-05-27 Thread Eric Mosley

I develope Java in work most of the time on my Linux machine (which is
great), but, a project has come up which will need a small persistant store
of objects/values, about 1000-3000 of them. Management has deemed that VB
with an Access file (which can be replaced easily) is the way to go. (Bye
Bye Linux for me).

What are the options for Java? Would a persistant Vector of objects not
slow down things terribly? Is there any other Access-like database routine
we could use which is free?

I'd prefer that all 1000 objects weren't read into RAM, some way to sql
them from their little file?

Any thoughts...




VB and Access == Java and ????

1998-05-28 Thread Eric Mosley



Thanks for all the responses! Most people suggested an rdbms with JDBC
which is something I'll look into.
But, seeing as how I know that there will be only about 2000 objects, what
if I just read them in and put them in a vector/linked list/hash table. In
your experience would that slow the app down/bloat it out too much for
comfort?
If it was C++ I wouldn't even worry about it.

Re: seg fault using Linux/Alpha JDK 1.1.5 for JNI

1998-08-19 Thread Eric Ding

Hi George,

My program consists entirely of this:

 #include 

 int main(int argc, char **argv)
 {
 JDK1_1InitArgs vm_args;
 vm_args.version = 0x00010001;
 JNI_GetDefaultJavaVMInitArgs(&vm_args);
 }

This should work.  I'm compiling with the following line:

 cc -o jnitest -I/include -I/include/genunix \
   jnitest.c -L/lib/alpha/green_threads -ljava

where  is the location of the JDK on my Linux/Alpha box.

Thanks,
Eric

I'm certainly interested.  Has Javasoft released reference
implementation source code?  If not then the project is more like
implementing the Java 3D spec on linux.  Which would seem to point
towards implementing the  Java 3D API on top of a pre-existing 3D
graphics library.  Isn't there a 3D project for gtk+ ?  

Then again with the AWT being Motif bound, gtk+ might not be the
optimal path.

I could help a bit, I have a cable modem connection that is up all the

set up a redirect from a site where I have a fixed address, but only a

I have plenty of space and bandwidth.

Obviously, a better offer would be if someone could provide space with

AWT problem with SWiM Motif 1.2 under alpha 117v2 port

1998-11-13 Thread Eric Bohm



I just upgraded to the jdk117_alpha21164a_bin and am having trouble
with some of the demo programs seg faulting or aborting while using
SWiM Motif. 

They all work fine when I set my LD_LIBRARY_PATH to use lesstif 0.87.
So this is not a critical bug.  But it is interesting nonetheless.

An example would be the 
appletviewer GraphicsTest/example1.html

It opens the appletviewer box, then immediately crashes before
displaying anything.

See the end of this message for an error outputs.

I'm using a 533Mhz LX processor.  
Redhat 5.2
kernel 2.0.35
glibc-2.0.7
The SVGA_XF86 driver supporting my Millenium SVGA.
SWiM Motif 1.2.4.

The Afterstep window manager.

JAVA_HOME, CLASSPATH, JDK_HOME are all unset.

I have not applied any of the kernel patches in the appendix yet.

Other AWT things like the MoleculeViewer work fine.  And I haven't had
a problem with any Swing-1.0.2 examples I tried so far.  

But the following demos from the binary distribution all failed.

CardTest
DitherTest
DrawTest
GraphicsTest

I exhaustively tried the other demos and they all worked just
fine. (Good job Mr Gatgul!)

Freetype seems to do a pretty decent job of providing True Type fonts.
It is opensource and integration with freetype is a compile time
option in XFree86.

Check it out at http://www.freetype.org/

Though adding yet another required library to the list for the JDK is
not optimal, this might be a good way to cope with SunSoft's new
direction. 

As a side benefit, it has already been ported to alphalinux.

free/malloc (re)defined in libjava.so?

1998-07-31 Thread Eric Ding

Hi,

I'm working on a project (Applixware for Linux) that uses the JDK
libjava.so internally.  We've stumbled on some sort of bug that I think
has to do with free() being redefined in libjava.so (it's not, for
example, in Solaris, so we don't encounter this problem).

I'm not sure much more what's going on, except that it'd be nice if
there were a workaround such that we could make sure to be using the
correct system functions (i.e., free, malloc, etc.), or an
implementation that didn't step on system calls.  Forgive me if I'm
asking the impossible, I don't know much of libjava internals.  As a
note, on our glibc port, we see this message:

> OUCH: nested memory code, to 1 levels.

while on the libc5 port, we're more apt to see either a massive core
dump or "Trying to free bogus memory" messages.

Any help you can give would be appreciated.

Thanks,
Eric



Re: jdk1.2 awt problems

1999-04-03 Thread Eric Vicario


I believe your using the link command incorrectly.  I could be wrong in
regards to Linux usage, but I believe the proper way would be;

ln {args} source target

the "->" shouldn't be there.  And you can link file to file, so I'd have to
look at this in Linux myself.  But I'd try it w/out the "->" first.

First, thanks for all the work you've done to get 1.2 onto Linux.

Second, a suggestion: could you put a link from your site (where you
mention that kernel 2.0.37 plus a patch is required for 1.2) to the
place where that kernel and patch can be found? The kernel archives
stop at 2.0.36

Thanks,

--Eric House

kernel 2.0.37 with Alan Cox's ac9 patch?

1999-04-13 Thread Eric GRAMMATICO

Hello team,

I already worked with your port of jdk 1.1, and it was really
excellent. Now I'd like to work on the jdk 1.2. But I had no chance to
find kernel patch 2.0.37 and Alan Cox's ac9 patch. Do you have any idea
where to find them ?

Many thanks for your excellent job.

good bye Eric.

Seeking source for Linux JDK 1.2 port

Hi:

The blackdown.org web site used to suggest that the patches necessary
to build the JDK on Linux were available.  Are they still?  Where?

Class not found

1999-07-26 Thread Eric Smith

Hi

A week of frustration and still we are unable to run any of the demos on our
Blackdown 1.2 installation.  Here is the error:

[root@plum Simple]# java SimpleExample
java.lang.NoClassDefFoundError: javax/swing/JPanel
at java.lang.Throwable.(Throwable.java:40)
at java.lang.Error.(Error.java:21)
at java.lang.LinkageError.(LinkageError.java:21)
at
java.lang.NoClassDefFoundError.(NoClassDefFoundError.java:21)

We are able to compile and run simple hello world text scripts.

The docs say no environment vars are required (except the path to java
itself.)  But of course we have tried setting and unsetting with no result.

Any suggestions.

Thanx

Quetion on IDEs

1999-09-11 Thread Eric vanberkel

Folks,

In this list some discussion was held about java IDE's on
Linux. Now all IDEs mentioned are java-based. Performance
isn't a thing you can show off with in java, so I wondered
if I should download Jbuilder or Netbean or whatever
similar IDE for use on my 48MB 150Mhz Pentium (Linux)
boz

Will running any of these become an annoying experience?

Anyone?

Jozilla?

1999-09-12 Thread Eric vanberkel

Folks,

I am looking for a nice coffee and cream project and came
across this Jozilla browser, said they needed help, were
part of a grand project called JOS.
I downloaded the user version but since it runs on 1.1 I
decided to upgrade the lot to 1.2 myself.
But I've got a few little questions (why the docs do not
match the software etc) but haven't been able to contact
anyone.

Does anybody know about this proj being dead or slumbering?
I feel it quite interesting to lift the browser to 1.2 even
if nobody's waiting on it; it's nice software though ;-)
For tech's sake anyway.

Anyone?

Yes, Greg,

now you have to juggle with most filemanagers extension

Moreover, since the sacred URL needs every character of a

To find classes or to be Applet thats....

1999-10-02 Thread Eric vanberkel

Folks,

Though I'm confessin' that I read a bit less than I should
maybe, why do applets in JDK 1.2 ignore my $CLASSPATH?
It worked with JDK 1.1.4 on my TurboLinux.
After installing, the applicable text to read says:
'No $CLASSPATh, no $JAVA_HOME, just run it!"

Fairly enthusiastic that, but what was wrong with Applets
conforming to my $CLASSPATH?
I found out apps DO mind the $CLASSPATH though.

I alwyas use a self-made script that goes

java -classpath .:$CLASSPATH $1

Howver, since I installed JDK 1.2-b-prev the script

appletviewer $1 &

does not function, and now I found out why.

Anyone?

Re: JDBC newbie question

1999-10-24 Thread Eric vanberkel

I've been thru this.

You go to check you have the 1.2.2 driver and not the
1.2.1, which did not work on my prev2 JDK + latest mysql

Also for apps:
java -cp .:$CLASSPATH proggie
with a correct classpath set

in applets $CLASSPATH won't work.
You'll want to put into your html:


..
..


put the mm jarfile in this tag and in the applet home dir.
If there is no jar, copy the mm.mysql level into the applet
home dir. I know it's a shame, butt...

If you haven't got a jar you use the jar tools to pack the
mm.mysql classes into a jar file.

This knowledge cost me a lotta sweat. I hope it pays off
for you brother...

Oh,
I managed to step over the line to PostgrSQL. Support for
JDBC is much better. This might be a hint. They also
upgraded to JDBC2 faster then mysql usually does

Good luck,

[Q] Displaying large image with MemoryImageSource

1999-11-01 Thread Eric Chao

Hi everybody, I had problems displaying a large image constructed from a

big buffer of int's using MemoryImageSource.  The maximum size it can
display seems to be about 600x500. Anything bigger than that will just
give me a white window. I checked the buffer and is very sure that
there's valid data inside and also had tested it under Window95 and NT.
It works fine under the Windows.

The following is the code that I use: (buffer is about 1700x1200)
(Problem arises when width and height is over 600)

public construct_image() {
Constructing buffer and setting its values here.
  ..
image = createImage
   (new MemoryImageSource
 (width, height, buffer,
  0, width));
  .
}

public void paint (Graphics g) {
setBackground(Color.blue);

g.drawImage(image, 0, 0, this);
}


Any suggestions is greatly appreciated.

How do I create a 1-bit depth graphics in memory?

1999-11-02 Thread Eric Chao

Hi, I am currently trying to create a 1-bit depth graphics in memory.  I
do not need color capabilities, just black-and-white. I am using a
buffer made up of integers but it is a waste of memory when I can use
1-bit for a pixel instead of 32-bits.  What is the best way to do that?
I need to switch to the more efficient way since Java complains
OutOfMemory exception on large images

[Q] problem with displaying image

1999-11-08 Thread Eric Chao

Hi, everyone, I am currently writing a Java program that displays an
image constructed from MemoryImageSource.  I start out by displaying the
"portrait" orientation of the image and have one button for the user to
toggle between "portrait" and "landscape" orientation.  The problem is
that when the program starts out in "portrait" orientation, I cannot
switch to "landscape". The only way I can display the image in
"landscape" orientation is to start out the program by displaying  using
"landscape" orientation.

Did anyone have this problem before? I'm using JDK 1.1.7 v3 (Black-down)
under RedHat 6.0.

Question about printing in Jdk 1.1

1999-11-12 Thread Eric Chao

I have an image that I wanted to print... This image is constructed
using MemoryImageSource using an array of bytes, with each byte
representing a pixel.
I also have a DirectColorModal to translate the color in each pixel.

 image = createImage
  (new MemoryImageSource
(d.width,
  d.height,
  dcm,/* Direct Color
Model */
  pixels,  /* array of bytes
*/
  0,
  d.width) );

When I tried to print the image. I keep getting this error(listed
below). But when I change the array of bytes to array of ints. It
worked.  But I do not want to store my data as ints when bytes works
fine... So any ideas???

idltojava for linux

2000-01-03 Thread Eric Mitchell


Hi,

I've seen a lot of talk on the mailing list archives about
the lack of idltojava for Linux.  Several people suggest
alternative idl compilers, but I have yet to find one that
works for the idl I need to process here.  I *can* use the
NT version to do what I need, but I'd much prefer an all-
Linux solution.  

How much work is involved in porting idltojava to run on 
Linux? Is it just a matter of tweaking some lex/yacc code 
(as someone suggested earlier)? Has anyone tried it?  How 
would someone volunteer to help this process?

Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable

I use Linux Debian 2.1 / blackdown JDK 1.2.0 (gclib 2.0).

Do I need to configure X in a special way to do this ?

Long pause before java browser finishes loading

2000-01-25 Thread Multanen, Eric

(Many apologies if this has been posted twice)

Hello,

I am using the ARM version of Blackdown's jdk 1.1.7 v3a
on a linux 2.2.3 based system.  GLIBC is 2.1 and no
distribution - the system is hand built.

I am trying to use the java based ICEBrowser (version 4 or 5).

The browser does work, but it takes 4 to 6 minutes to load.
Running the browser in verbose mode shows the classes that
are loaded.  After the browser reports loading
'java/awt/EventDispatchThread.class' is when the long pause occurs.

During this pause, the CPU utilization approaches 100%.  Attaching
strace to the process shows that poll() is being called on
the standard fd's, class and jar file fd's, and one UNIX socket.

Eventually, whatever is running finishes/times out and the browser
continues loading classes with 'sun/awt/motif/InputThread.class'
and a bunch more.

So, I'm looking for any ideas on what might be happening during the
pause.  Perhaps there is a service or something that it's looking
for that I don't have on my system?  Or maybe some kind of thread
issue?

Thanks,

Eric Multanen

idltojava on Linux - SOLUTION using WINE

2000-01-31 Thread Eric Mitchell


Having beat up wine, idltojava.exe and so forth to do 
idltojava compiling without leaving the linux box, I 
figured I'd share the information.  Feel free to include
this in a FAQ.  It Works For Me, Your Mileage May Vary.

-

To perform idltojava processing on Linux you will need:


1) A recent distribution of wine from http://www.winehq.com. Wine is 
a windows binary loader for Linux.  It is capable of running a fair
amount of Windows executables on Linux.


2) Something equivalent to the following in your ~/.winerc file.
Substitute the path to your java development tools area for /opt/java
if necessary.  I keep all my java development tools under the
/opt/java directory, e.g. /opt/java/jdk1.2.2, /opt/java/jikes, etc.

[Drive J]
Path=/opt/java
Type=network
Label=java
Filesystem=win95

You should set up a similar network drive entry if your java source
files are kept in a different directory tree.


3) Sun's idltojava utility for Win32 platforms.  Download this from
http://developer.java.sun.com/developer/earlyAccess/jdk12/idltojava.html

Save the downloaded file as /opt/java/idltojava-ea-win32.exe
Extract the archive by: wine /opt/java/idltojava-ea-win32.exe

This will create a directory /opt/java/idltojava-win32, and store the
executable and documentation in that directory.


4) To compile idl files using idltojava.exe:

First, preprocess the idl using g++.  Gcc might work, but I haven't
tried it personally.  Include any predefined symbols and include paths 
(e.g. -DSYMBOL -I/some/idl/include/dir) as "other options", below.
The following line stores the output of the preprocessed file.idl as
Jfile.idl:

g++ -E [other options] - < file.idl > Jfile.idl

Second, invoke idltojava.exe via wine. Include the option "-fno-cpp"
to avoid invoking the preprocessor again.  You may want to include the
option "-fmap-included-files" to create java stubs/skeletons for
interfaces which are included via #include directives in the idl file:

wine /opt/java/idltojava-win32/idltojava.exe \
-fno-cpp -fmap-included-files Jfile.idl

This creates a multitude of java source files.

Last, depending on which ORB you are attempting to operate with, you
may need to strip out the "IDL:omg.org" portion of the interface
specifications in the java sources.  This was required to interoperate 
with TAO (http://www.cs.wustl.edu/~schmidt/TAO.html).  Basically, if
you run into problems connecting to a server, try the following and
see if it works:

sed "s@IDL:omg.org/@IDL:@g" $file > $file.tmp ; mv $file.tmp $file

You will need to do this for each .java file generated by idltojava.


I use the following in my Makefile to perform processing via
idltojava.  The double quotes in the wine invokation are significant..  

-

IDLCPP   = g++
IDLCPPOPTS = -E -DDEFINED_SYMBOL \
-I/include/path/to/any/included/idl/files

WINE = /opt/wine/bin/wine
IDLJAVA  = /opt/java/idltojava-win32/idltojava.exe
IDLJAVAOPTS = -fno-cpp -fmap-included-files

FIX_JAVA = /opt/java/fix_java.sh

FILEIDLJAVA = \
first___java_file_output_from_idltojava.java \
second__java_file_output_from_idltojava.java \
... \
lastjava_file_output_from_idltojava.java

$(FILEIDLJAVA): file.idl
$(IDLCPP) $(IDLCPPOPTS) - < $< > J$<
$(WINE) "$(IDLJAVA) $(IDLJAVAOPTS) J$<"
$(FIX_JAVA) $(IPCIDLJAVA)

-

The following is fix_java.sh as referenced in the Makefile rule above:

-

#!/bin/sh

for file in "$@"; do
echo Fixing: $file
sed "s@IDL:omg.org/@IDL:@g" $file > $file.tmp
mv $file.tmp $file
done

-

Problem with 1.3 and J2EE1.2.1

2001-06-27 Thread Eric Richardson

Hi,
A few days ago I installed on Debian 2.2 the j2sdk1.3 from the debian
file.

$ java -version
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build
Blackdown-1.3.0-FCS)
Java HotSpot(TM) Client VM (build Blackdown-1.3.0-FCS, mixed mode)

I also JAVA_HOME set.
$ echo $JAVA_HOME
/usr/lib/j2sdk1.3

I was previously running 1.2.2 tarball from Sun and had no problems.

Here is the error (typed from dialog box) when I tried to deploy some
working apps.

There was a deployment error. java.rmi.ServerException: RemoteException
occured in server thread; nested exception is: java.rmi.RemoteException:
Error processing ejb jar: access denied (java.io.FilePermission
/usr/lib/j2re1.3/lib/ext read)

>From deploytool window
...
Remote message: Deploying Ejbs
Remote message: Processing beans 
Remote message: Generating wrapper code for BankAccountEJB.
Remote message: Compiling wrapper code 

No hints in server window.

I tried messing with the jre java.policy.
# cat java.policy
grant {
  permission java.security.AllPermission;
};

No luck. The server.policy and client.policy for the J2EE both have
FilePermission for the ext dir.

Any help appreciated,
Eric

I added to the grant section of the server.policy for the J2EE.

grant {

   ...
   permission java.security.FilePermission "<>", "read";
 };

I tried file:${java.home)/lib/ext/- and various other variations to
narrow it down with no luck.

I think emacs or xemacs with JDE is a good solution. The trick is to
have classpath set for your project before starting up so the compile
with jde will work and also having the -d for the classes output dir
set. I set an env var named CLASSES_DIR and then just set -d
$CLASSES_DIR for the javac option. I also use ant for the build as well
but ant is too slow to build one class.

JDE

Hope this helps,

Hello,
You said you have an editor "that makes life easier". What's that for?
Thanks for your answer.

jdk-1.2 out of memory errors...

1999-04-22 Thread Benedikt Eric Heinen


Hi there,

  I just installed the pre-release 1 of jdk1.2 on my system and as stated
in the README included its bin directory in my PATH. But - even trying to
run a simple HelloWorld fails with an OutOfMemory error (and I am somewhat
certain that there is enough memory left [unless, 900MB free memory would
be too little]):

  beh@fenun:~/src/j $ java HelloWorld 

  *** panic: GC: getStickySystemClass failed: java/lang/ref/Reference
  CLASSPATH may be incorrect

  Swap:   770504  0 770504



Also, what I find strange is the mentioning of a possibly incorrect
CLASSPATH -- no CLASSPATH is set in the environment, and according to the
README, that should be OK...

Btw. trying "javac HelloWorld" yields the same OutOfMemory error (I still
had an old .class file around to test the "java HelloWorld" with).


I have a pretty current Debian/potato (glibc-2.1 setup) -- last dselect
upgrade is 24h back, with a 2.2.5 kernel on a Dual P-II machine.


Any clues?

Too old an Applet?

1999-08-10 Thread eric van berkel

Hi,

I've put together an applet that queries a database over a JDBC connection.
When I run appletviewer all's well.
When I use Netscape 4.5, ok.
However, Netscape 4.5 puts a bit too much strain on my system to work flexibly with.
Using the 'lighter' Netscape 3.01 (still a staticly linked colossus ;-) I get the 
strange message:

'Cannot load applet. The zip file's so old it hasn't even got a version to it'

Apart from the strange sense of humor used I don't really get the point. NS 3.01 
should run this applet.
Which zip file? classes.zip is in my $CLASSPATH...

I'm using JDK 1.1.6 on TurboLinux 3.0

Appreciate your help.

Gr. Eric

I don't think SUN itself is hostile to Linux. I think Java is the outcome of an 
idealistic view shared by some (and a funding company with commercial interests), the 
both of which clashed as always.

Now Blackdown care about Linux, otherwise they wanted to get paid for this 
hercules-job they're doing.
Blackdown do not respond to market stress (as far as I'm told, and they got some stuff 
to fix), and this is just, because they're not commercial.

So the company wants to cash in short term and forgets about the long-term cash flow 
called Linux by not entering the Linux arena. This is Sun's prime mistake. Now IBM 
will grab their pretzels and eat 'em!
HAH WILLIE!

IBM's got powerful Net stuff on their OS/390 platform already. Soon as they port 
Linux, they'll port OS/390. They from that point in time have -
1. strongest on mid-range servers (linux)
2. strongest on JAVA and NET connection (Linux, AIX, and OS/39)
and of course already serice the most part of coorperate data in the world on their 
MVS databases.

This is the world according to I.

[Q] CORBA: Any idltojava for linux??

2000-01-19 Thread Eric / Chang-Cheng, Chao

Hi, I want to write some CORBA-compliant java programs and I need
"idltojava" in order to convert the IDL  files to Java files.  I checked
the Sun's website and I found versions for Sparc Solaris and Windows but
none for Linux. Can anyone tell me where I can get it if there is indeed
one available? Thanks.

Chang-Cheng (Eric) Chao
