Java 2 SDK on Red Hat 8.0

I downloaded and installed Java 2 SDK 1.4.0 on my RH box. when I try to run java or javac I get the following message:
libjava.so not found
Cannot Find JRE
How can I correct this?

Have you set the SDK up?
export JAVA_HOME=/path/to/j2sdk1.4.0
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.
If so, locate the libjava.so file manually and "ldd /path/to/libjava.so". If any of the libraries listed are not found, you may need to download and install them using http://rpmfind.net/. If no libjava.so is found, do ldd on your java file.

Correct version of Java SDK for Red Hat 4 ES on x86_64

I need to install the Java SDK for Red Hat 4 ES on x86_64 and I'm unable to find the correct version to download.
Note 716604 says to download 1.4.2_13 at java.sun.com but the I can't find the Linux x86_64 bit version. Note 941595 is for Windows and Solaris only.
Red Hat's site mentions two versions; java-1.4.2-ibm and java-1.4.2-bea. I cannot find any SAP notes that mention those names. Has anyone used these successfully on Red Hat 4 x86_64?
Does anyone know where I can download the correct version of Java SDK?
Thanks

Q:Java installation in Red Hat?

Hi,
I've been using JRE v1.4.2 in Redhat Linux, but have just installed v1.5.0. When I run "java -version" it still says I'm using version 1.4.2. How do I get the new version to run?
Robert.

Thanks, it's working now. :)Cool. In fact, it assumed you previously had the link to the java binary in that place, and no other link to a java binary anywhere in your $PATH or, even a JAVA_HOME /bin dir in the $PATH itself. You should check that to avoid collisions.

Java(TM) 2 SDK needed for Red Hat Enterprise 4

Hello List members,
I am installing open-xchange on my Red Hat Enterprise 4 box but getting error "no acceptable java compiler found - please install at least the Java(TM) 2 SDK."
JRE is installed in my system but even after a lot of research I am unable to find Java(TM) 2 SDK . Can anyone of you tell me where to download Java(TM) 2 SDK for Red Hat Enterprise 4. Its not in the SUN site as far as I know, I could be wrong.
Please help me.
Regards,
Vishal

Installing Java EE SDK on 64-bit Red Hat Linux

I've went through a lot of pain to get J2EE SDK / GlassFish server on a AMD64 Red Hat Enterprise Linux 5 server box. Maybe it helps somebody.
Long story short, it all seems to boil down to the fact that the J2EE Linux .bin (non-RPM) packages Sun provides require a 32-bit JVM running. So if you just installed 64-bit JDK you're toasted.
Chronicle of pain and solution below:
Downloaded the Linux packages for full EE5 SDK, also the bundle for GlassFish from http://java.sun.com/javaee/downloads/
Tried ./java_ee_sdk-5_08-jdk-6u17-linux.bin No luck. First I didn't have libstdc++.so.5 but so.6. I did
yum install compat-libstdc++-33
Tried again. It hanged:
*** glibc detected *** ... double free or corruption error
Downloaded the JDK RPM version. It worked fine:
# java -version
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01, mixed mode)
Let's go again with EE SDK. Nope. Different error this time:
*** glibc detected *** ./java_ee_sdk-5_08-jdk-6u17-linux.bin: malloc(): memory corruption: 0x0992d2c0 ***
Tried setting env variable MALLOC_CHECK_:
export MALLOC_CHECK_=0
New error, but no hanging this time:
Attach to native process failed
Realized that JDK packages were platform-specific, unlike J2EE packages. Googled this: http://forums.java.net/jive/thread.jspa?threadID=37370
Downloaded 32-bit JRE (i586, not 64-bit) RPM package and installed it.
Redirected default java link to 32-bit JRE's JVM:
cd /usr/java/
unlink latest
ln -s jre1.6.0_17/ latest
Run installer again, explicitly saying where was the JVM the installer needed:
cd /tmp
./java_ee_sdk-5_08-jdk-6u17-linux.bin -javahome /usr/java/jre1.6.0_17
It worked! :-)
Then reverted back to JDK's 64-bit JVM:
cd /usr/java/
unlink latest
ln -s jdk1.6.0_17/ latest
Hope this works for you too.

This is very close to my problem,
32 bit Fedora release 11 (Leonidas)

Using Linux/Red Hat/Intel for Sun ONE/Java Directory Server

Anybody have any experience of this? We're looking to get off AIX, and Total Cost of Ownership for using Solaris/Sparc versus Linux/Intel is very similar.
The decider will be if no-one is using Linux as a platform for Sun ONE/Java Directory Server....
Any feedback would be appreciated....

We run Directory 5.1 in production on Solaris/Sparc, but I've tried it with sucess on Red Hat 7.2 on Intel. We have not been able to get it to work on Red Hat Enterprise 2.1 or 3.0. The main problem has been that the administration server fails on startup. Obvious the lack of support for the latest enterprise class Linux is a huge drawback. At this point I've decided to stay on Solaris/Sparc until Red Hat comes out with its own release of Netscape's Directory. When that happens we're going to evaluate whether to move the whole environment to Red Hat. The Sun and Netscape servers are almost identical in terms of features and performance, but having an open source version that can run on less expensive hardware would be a terrific win for us.

Sun Java System Web Server support for Red Hat EL 5

Does anyone have any information when the Sun Java System Web Server might be supported on Red Hat Enterprise Linux 5 Server?
Thanks

Certification of RHEL5 will likely happen with one of the upcoming Update releases.
There is, as far as I know, no reason why Web Server won't run on RHEL5 today though (I use it on Fedora Core 7 without ill effect, and the RHEL trail the Fedora releases a bit in technology versions).

How to install Java on Red Hat

Does anyone know how to install Java on Red Hat. I'm having problems installing it, and I can't really find any instructions anywhere on how to go about it. Thanks.

Java won't run on Red Hat because of firewall
problems.What ? Since when ? But there are problems with certain versions of RH.
Nothing to do with a firewall though.
>
It only runs on Sun and Windows 95.
But not the Vax version.

Installation the Java Runtime Environment (JRE) on Red Hat Enterprise Linux

Hi gurus,
I´m trying to install an ECC 6.0 SR3 (ABAP) on RHEL v.5 with Oracle DB.
But as I am newbie I have some doubts, in this point is with the Java Version JRE that is required in sap installion process.
I already installed the JRE through RPM Package File (I followed the instructions/steps described in this url - http://java.sun.com/j2se/1.4.2/jre/install-linux.html ) and I don´t have any problem... by the way I installed the JRE version 1.4.2_25 b02.
But after the installation I had a question, how do I check if the package was installed correctly? I insert the commad java -version, and the result was this:
java version "1.4.2"
gij (GNU libgcj) version 4.1.2 20080704 (Red Hat 4.1.2-46)
Copyright (C) 2006 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
With this information I really do not know if the version 25 was installed...
I already check if there is some directory with the new file, and actually there exist in the directory /usr/java but this is not tell me if this is the new one!!
It´s possible to know which one is installed with other command by terminal?
Best regards,
Joao Dimas - Portugal

1- Ok Markus, but for me it is strange how I could know that the JDK was wrong, that because I don´t know why I have to install this component for IBM JDK ...... This server has a x86_64 bit architecture, where is related to IBM? I did not understood that sorry... and the component that is installed is 1.4.2 JDK with last version which is 25 to x64 bit (for my x86_64 architecture) ... Forgive my ignorance here, but I don´t understand Markus! Where there is a relationship with the AMD64 architecture? If you are correct... if this is a AMD64 therefore I have to download new installation media DVD´s for this installation for AMD64 architecture, isn´t it? Because all the dvd's that I have here to install this system is refer to the version x86_64!
X86_64 == AMD64 == x64 see
http://en.wikipedia.org/wiki/X86-64
This is all the same. AMD invented the "64bit extension" for their x86 CPUs, later Intel licensed that extension. All those terms are synonyms.
So if
java -version
does not give you the IBM JDK your installation will fail.
If you check the PAM (http://service.sap.com/pam) you'll see that for 64bit Linux (AMD64, x86_64, x64) only the IBM JDK is supported because Sun has no 64bit JDK for this (ancient) version 1.4.2 for Linux x86_64.
[root@redhatsap IM_LINUX_X86_64]# swapon -s
> Filename Type Size Used Priority
> /dev/mapper/VolGroup01-LogVol01 partition 5931000 0 -1
This means that I have about 5,9 Gb of RAM memory?
That means that you have 5,9 GB of SWAP. You get your total memory using the command "free" or use the command "top".
If I need to allocate more memory, as sap recommends 2xRAM, with 8 GB of RAM, how can I do that, in installation guide it tell me to go read the manual for linux... what documentation?!
Honestly, this here is not the place to learn Linux.
I'd use e. g. Google and enter "Redhat 5 add swap space"
http://centos.org/docs/5/html/Deployment_Guide-en-US/s1-swap-adding.html
(btw: CentOS is a RedHat clone, it's the same software and so the same commands).

Install Problem on Red Hat 7.1

When I try to install Oracle 8.1.7 on Red Hat 7.1, and run the
runInstaller, but nothing happens. Even no Welcome Page is
displayed.
[oracle@localhost Disk1]$ ./runInstaller
Initializing Java Virtual Machine
from ../stage/Components/oracle.swd.jre/1.1.8/1/DataFiles/Expande
d/linux/bin/jre. Please wait..
[oracle@localhost Disk1]$
I have create the group and user for installation, install Java
SDK 1.3.1 and set the path. Can anyone show me some directions
about what is the problem and how to solve the problem?

Thanks Olaf Tiemann,
I have not installed those packages yet and try the installation
again.
Finally I install the Oracle successfully and get the DB
running, though there are still 2 minor errors.
1. Error in invoking target relink of
makefile /oracle/OraHome/ctx/lib/ins_ctx.mk, the patch glibc-
2.1.3-stubs.tar.gz seems does not relink/replace this .mk file
2. Error when running the Root.sh, there are 2 sytnax errors at
the beginning of the script
It will be perfect to get rid of these 2 errors.
Anyway, my DB gets running.

Java SDK compatibility under RHEL 4 and WLS 8.1 SP5

I am in the process of installing BEA WebLogic 8.1 SP5 under Red Hat Linux ES 4 on x86 processors, and am verifying the supported Java SDKs. Accoriding to:
http://edocs.bea.com/platform/suppconfigs/configs81/rhelinux40as_es_x86/81sp5.html
only the JRockit JDK is listed. Is this implying that Sun's JDK 1.4.2_08 is not supported under this configuration?
The installation binary installs both Sun's and Jrockit's JDK.
Thanks for your assitance.
