I have the binary distribution from Uncle George. jdk116_alpha_21164a_linux_bin_v1.gz jdk116_alpha_linux_classes_v1.gz But found some problems when trying to use habanero on top of it. Further, I'd be interested in getting the diffs so I could try them on jdk117 and help out with the alpha port.

question about installing
Hi, i'm not sure if this is the right email address to send a question of this nature to, i apologize if it isn't. I just downloaded the file jdk_1.1.6-v5-glibc-x86-tar.bz2 and i am unsure how to install it. I am new to Linux, and i am aware of the command 'tar zxvf filename', but i get an error message that it doens't look like a tar archive. i tried renaming to a .Z and .tar extension but it didn't work. thanks.

If you are using RedHat < 5.0 try ftp://ftp.redhat.com/pub/contrib/i386/bzip2-0.9.0b-1.i386.rpm if RedHat > 5.0 ftp://ftp.redhat.com/pub/redhat/redhat-5.1 (or 0)/RedHat/RPMS/bzip2-0.1pl2-1.i386.rpm If you have other linux distribution try http://www.digistar.com/bzip2/bzip2-*.* After this try: bzip2 -d jdk...tar.bz2 and you'll obtain the tar file. Run: tar -xf jdk..tar and you'll obtain that you wish. Another way (if you have a RedHat distribution installed on your machine) is to install the jdk rpm's from: ftp://ftp.redhat.com/pub/contrib/i386/jdk.rpm ( RedHat <= 4.2) or ftp://ftp.redhat.com/pub/contrib/hurricane/i386/jdkrpm ( RedHat >= 5.0) Good luck, === Sorin LINGUREANU ([EMAIL PROTECTED], [EMAIL PROTECTED]) Network Administrator in Data Communication Center "Gh.

Yup, that is what would happen. If you want to use the dynamically linked Java with AWT you need to set DYN_JAVA=true. This version will need to have Motif shared libraries on your system. Normally you would not set either DYN_JAVA or NS_JAVA if you want to run AWT and do not own a copy of Motif. NS_JAVA is mainly there so that you can run non-GUI Java applications without X-Windows installed. Such as server-side applications/servlets. This reduces the size of the memory used and does not require that X be installed on the system.

Tar also does not directly know about bzip2 (at least the versions I have) So, you need to get BZIP2 to decompress the file and then run that through "tar -xf". Otherwise you could download the .tar.gz version of the file. It is the exact same tar file only with gzip compression. This normally is very easy to extract since tar tends to know how to deal with this if you use "tar -zxf" (the -z tells it to use gzip filter) 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
Re: libawt.so purgatory
Thanks to Mr. Watson and Mr. Sinz for replying. Yes, changing the NS_JAVA environmental variable worked. At some point in the install procedure I had set it in an attempt to resolve an earlier difficulty... but instead of unsetting it, I unset, as my earlier note suggested, JAVA_NS. Heh. Thanks again. - Jon
installation?
Hi there - I'm an experienced linux user but brand new to java. I've followed the directions in the linux java faq (http://www.blackdown.org/java-linux/docs/faq/FAQ-java-linux-3.html#ss3.2) for installation on (a rigorously patched) i386 RH 5.1: --(snip)-- $ tar zxvf /tmp/jdk1.1.6.tar.gz $ export DISPLAY=:0 $ export PATH=/usr/local/jdk1.1.6/bin:$PATH $ appletviewer \ /usr/local/jdk1.1.6/demo/awt-1.1/lightweight/OpenlookButtons/example.html --(snip)-- All easy enough, except that the jdk_1.1.6-v5-glibc-x86.tar.gz file doesn't seem to contain a "demo" subdirectory or anything called "awt". Just "lib", "bin", and "include". Are there other files I need to get and install for a complete installation? Additionally, there is a "biss-awt" subdir on the ftp site with multiple versions and I'm confused about which (if any) that I need and where (if anywhere) I would put them under the "jdk116_v5" subdir. They also contain no "demo" subdir. One more thing, what are all the other files in the "i386" directory: rt_1.1.6-v5-glibc-x86.tar.gz jre_1.1.6-v5-glibc-x86.tar.gz i18n_1.1.6-v5-glibc-x86.tar.gz What are they, are they required, and where do they get installed? Please enlighten me. I'm really confused and just want to write java GUIs. Thanks! -- Clint Miller - KD5BYY http://www.infinop.com/ Infinop, Inc. mailto:[EMAIL PROTECTED] 3401 E.

Sending objects down a stream problem
I'm almost sure this is one of those problems cuased by
my misconception of how things work in Java v.s. C++,
but I have run this thing around for days without resolve.
Maybe someone can see the obvious
I'm trying to send a serialized class down a network pipe and am
only getting the first one on the other end. The rest seem to vanish.
The concept is to have a gpsStat class serialized and sent down the
pipe each second to a client that will display it. My code appears
to be working for the most part except that the object sent from
the server to the client never changes from the first one I sent.
On the sending end I have:
gpsStat y=new gpsStat(); //make object to serialize
while(true)
{//fake data into gpsStat
y.month++; y.day++; y.year++;
sleep(500); //fake pause to simulate GPS reciever
objOStream.writeObject(y); //send it
objOStream.flush();
}
while(true)//keep printing out objects as they arrive
{
gpsStat g=(gpsStat)objIStream.readObject(); //get object
System.out.println("server returned -> "+g.toString()); //print
object
}
Anybody see my mistake?

The rest seem to vanish. [code deleted...] You are trying to send the same object down the same (already open) object output stream. The serialization stuff keeps track of what was sent already and does not send it again. You can either send new objects or close and open new streams for each one.
