Hello,

Some time ago (rather long time :?) I came across a guide how to install IBM Java on Debian/Pegasos. Unfortunately I saved only URL to this guide which doesn't work anymore :( I downloaded necessary files from IBM but basically I have no idea what to do next. Can anyone help?

Go to http://www-128.ibm.com/developerworks/j ... nload.html
click on J2SE 1.4.2 or 5.0 for 32-bit iSeries/pSeries
Sign in (you have to register if you don't have accout on IBM - it's free)
and download TGZ format of
"JRE" e.g ibm-java2-jre-50-linux-ppc.tgz (45.8MB)
and
"Java Communication API" e.g. ibm-java2-javacomm-50-linux-ppc.tgz (122KB)

If you know what to do next please let me know :wink:

THANKS !!! I would have never looked closer to
something called i/pSeries ... now I have to wait
for some hours since my modem is a little slow @ downloading 63MB ;-)

When I have eclipse running I'll let you know :-)
Next step is to find how to setup Tomcat ...

Installing worked.
Extracted the archive renamed it to java and moved it to /.
All I had to do was to install libstdc++5 and java worked.
I set the variables (in /etc/profile)
JAVA_HOME=/java/jre
CLASSPATH=/java
PATH="/java/bin:/java/jre/bin:$PATH)

But I totally fail to find why Eclipse does not work ...
so I have not tested further ...

How did you tested java?? I tried to test it with Konqueror but any WWW which requires JVM doesn't work at all. I mean java part is not working - try www.map24.com and tell me if it found JVM on your system.

I use it with Eclipse and there it works now.

Konqueror and Firefox dont look for the jvm.
They need a plugin in certain directories.
There are some plugins located in the jre/bin directory
and after adding the path to the Konqueror Plugin-Preferences
it finds the plugin, but it does not work :-(

Dont know why ,,, but in the Firefox Faq it seems the plugin
has to be compiled with the same compiler as the browser.
I'll try to download and compile Firefox with gcc 3.2 ... perhaps
that helps (Ubuntu's Firefox is compiled with gcc 4.0).

This website shows that Konqueror finds and uses
the plugin ...

http://www.java.com/en/download/help/testvm.xml

... Firefox finds the plugin, too (It's listed in about:plugins)
but this test fails :-(

Hours later ...

I got Firefox to use Java after I totally failed to compile it myself ;-)
Code:
robin@Pegasos:/usr/lib/mozilla-firefox/plugins$ ls -la
insgesamt 4
drwxr-xr-x 2 root root 81 2005-12-28 23:11 .
drwxr-xr-x 11 root root 4096 2005-12-26 21:37 ..
lrwxrwxrwx 1 root root 27 2005-12-28 23:10 javaplugin.so -> /java/jre/bin/javaplugin.so
lrwxrwxrwx 1 root root 35 2005-12-28 23:11 libjavaplugin_nscp.so -> /java/jre/bin/libjavaplugin_nscp.so
lrwxrwxrwx 1 root root 34 2005-12-28 23:11 libjavaplugin_oji.so -> /java/jre/bin/libjavaplugin_oji.so
I've linked these three files into the plugin directory. (Copy does not work)
This shows on map24 at least a "Java loading ..." and then it crashes ;-)
I dont understand this ...
Code:
robin@Pegasos:/usr/lib/mozilla-firefox/plugins$ firefox

Hi!

I posted my problem to debian-ppc ml and thanks to people from the list and after some googling I have the solution :)

To install IBM JVM go like this:
apt-get install java-package
download java-package.patch to /usr/share (see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=338569)
cd /usr/share
patch -p0 <java-package.patch
cd /home/bla/ibmjava (where ibm tgz file is downloaded)
(as user)
fakeroot make-jpkg ibm-java2-jre-50-linux-ppc.tgz
(as root)
dpkg -i ibm-j2re1.5_1.5.0_powerpc.deb
put path to Java in Konqueror (/usr/bin/java)
logout, login
and JavaJVM works fine!!

I still can't get JVM plugin to work with Mozilla/Firefox - if someone will be able to use JVM with Mozilla/Firefox please let me know!

I didn't manage that way ...

Can U give me more details about libstdc++5 installation ???

Tnx in advance from a new pegasos II G4 user...

@KiLL :

Hi !

Here is how to install libstdc++5.

I did that on Ubuntu which is based on Debian :
(see Ubuntu + enlightenment e17 window manager for details).
It also fixes problems like "undefined reference to `memcpy@@GLIBC_2.0'".

1) Remove gcc-4.0 if it's installed :
apt-get remove gcc-4.0
(It will also remove g++, g++-4.0, gcc, gcc-4.0, libstdc++-6-4.0-dev)

2) Install gcc-3.3 :
apt-get install libstdc++5-3.3-dev
(It will also installs cpp-3.3, g++-3.3, gcc-3.3, libstdc++5)

Then do a few links by yourself :
cd /usr/bin
ln -s cpp-3.3 cpp
ln -s g++-3.3 g++
ln -s gcc-3.3 gcc

cd /usr/lib
ln -s /usr/bin/cpp-3.3 cpp

Now you will use the right stdlib ;-)
Hope that helps.

[quote="bazant"]Hi!

I still can't get java plugin to work with Mozilla/Firefox and Konqueror under my debian/GNU Linux installed on my pegasos II G4.

Can anyone let me know how to correctly install java (and other web browser plugins such as PDF, swf, Real Player, plugins ???

Tnx in advance

Finally I managed to successfully install and use both java and flash plugins.
Probably, the java plugin is still partially usable since some applets just don't start...
Much more probable that I missed something during pkgs installation :-)

Also the test Robin suggested connecting http://www.java.com/en/download/help/testvm.xml didn't return me nicer results...

Any suggest ???

BTW! Tnx. to Bazant and mcgreg for great help with installing JVM pkgs!

@AKILL

Erm, I think I told you something wrong :)
As I did the same error for me too.. wrong path is set in /home/user/.bashrc.

export PATH=/opt/ibm/ibm-java2-ppc-50/jre/bin:$PATH

it should be.

If it is correct:

After opening new console,. by typing export, you should get:
declare -x PATH="/opt/ibm/ibm-java2-ppc-50/jre/bin:...

and by typing "which java"

the result should be:
mcgreg@pegasos2:~$ which java
/opt/ibm/ibm-java2-ppc-50/jre/bin/java

Then it should work ok.
