I installed the java file i.e "jdk-6u18-linux-i586". And it is installed without an error. But when I execute the command "java -version" it doesn't show the above version, it shows the previous version which I installed during the installation of redhat enterprise linux server 5.

So, what is the problem guys?

Please, help me.

Thanks!

Hi,

When you ran the installation sciprt jdk-6u18-linux-i586.bn, it created a directory jdk1.6.0_18.
You must run java from this directory in order to use the new version, or change the PATH variable and add the complete path to the above directory first:

Hello,

I'm also facing some problems with Java installation.
I got a Red Hat Linux Enterprise 5.3 on an Intel 64 bit system.
Typing "java -version" I get

java version "1.4.2"
gij (GNU libgcj) version 4.1.2 20080704 (Red Hat 4.1.2-44)

meaning that some Java RE version is already installed.
I need to install the JRE 1.6 update 10 (not the latest).
After some googling, the best I found is jre-6u10-linux-amd64.rpm (extracted from jre-6u10-linux-x64-rpm.bin).
I'm not sure whether this rpm is suitable for an Intel-based system (I see 'amd' in the name)?
I tried to install it anyway (rpm -ivh ...), got this:


Preparing... ########################################### [100%]
1:jre ########################################### [100%]
Unpacking JAR files...
rt.jar...
jsse.jar...
charsets.jar...
localedata.jar...


but nothing seems to have changed (same java version, no new directory created).

Any hint?

@zeroquaranta
Before anything else check /usr/java/ to see if latest is already installed. In that case just change your PATH:
Otherwise there should be a jre-6u10-linux-x64-rpm in the place where you ran jre-6u10-linux-x64-rpm.bin. Use rpm to install:

Hi bathory,

I actually got the dir /usr/java/jre1.6.0_10 meaning that the rpm installation I did sorted out something.
And when I move on that directory and type './java --version' I get

java version "1.6.0_10"
Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
Java HotSpot(TM) 64-Bit Server VM (build 11.0-b15, mixed mode)


as wished.
Now, I think 2 versions are installed on the system, I only need to arrange the PATH variable in order to have the new version launched when I type "java" from whatever directory.

As for the rpm thing, I actually got one after the execution of the .bin file. The thing is that the names are different

jre-6u10-linux-x64-rpm.bin -> jre-6u10-linux-amd64.rpm

and, since I see 'amd64', I'm wondering whether it is suitable for my Intel-based server.

Thanks a lot.

Hi,

In java.sun.com now there is only jre-6u18-linux-x64-rpm.bin (maybe jre-6u10-linux-amd64.rpm was the name for previous versions)
You can check your installed version with:
and maybe upgrade to the last version

Ok, forget the PATH thing, I followed your instructions and now it seems that the new version is recognized ('java -version' from anywhere).

Ok,
returns
which looks good.

As I wrote, I just need the "update 10", not the latest one; thus grabbed
jre-6u10-linux-x64-rpm.bin
from the Sun website. But when I run it I get
jre-6u10-linux-amd64.rpm
which is the one I installed.

You should better use a package made for RHEL based systems, so you can upgrade. You can get the correct package from here.
And I guess you have to uninstall the 32bit version prior installing the 64bit

Ok, via the link you posted I found this

jdk-1.6.0_14-fcs.x86_64.rpm

which is exactly (apart from the update version) what I see in the Gnome Packages Manager, in the installed packages list (jre-1.6.0_10-fcs.x86_64).
At this point I'm not sure why the rpm I downloaded from Sun website has a 'amd64' in it.
I'm gonna try and see if it works, anyway.
Thanks a lot! I.O.U a beer!

PS: as for the previous installed version, which came with Red Hat, it appears in the same installed packages list as
java-1.4.2-gcj-compat-1.4.2.0-40jpp.115.x86_64; I didn't uninstalled it, gonna see if it causes any problem
