Java installation on hpux is a tricky one. Not because of the process but because of the selection. Your server may host more than one java version and it is upto the application to decide which one to use and adjust its running environment.

Java installation is usually asked by a third party application provider and they have to specifically tell you which version to the 3rd level subversion that they want, as every minor version change may have significant effects on the developer's code. First ask them which version and sub-version they are comfortable with (example 1.4.2.08 or 1.3.1.17 etc)

then go to

http://www.hp.com/go/java

find the specific version or one closest to that. Then go to this page:

http://www.hp.com/products1/unix/java/patches/index.html

and find out which set of patches are applicable to your case and download them.

using swinstall and basic sysadmin skills, first load the patch set and let the server reboot if necessary.

Then you will be able to install java downloaded from the first URL above. It willnot require a reboot.

But most important aspect of this explanation is to ASK the user what they need, more than anything else.

you do not have to install an old version to be able to install a newer one. They are independent of each other.

to check if you have any java installed on your server

ls -l /opt | grep -i java

if you have any installed base, you will see it listed as a directory with every major version, like

ls -l /opt | grep -i java
dr-xr-xr-x 9 bin bin 1024 Feb 24 2000 java
dr-xr-xr-x 4 bin bin 96 Dec 20 2003 java1.2
dr-xr-xr-x 3 bin bin 96 Dec 20 2003 java1.3
dr-xr-xr-x 3 bin bin 96 Dec 20 2003 java1.4

to figure out which minor revision you have under each directory:

# /opt/java1.2/jre/bin/java -version
java version "1.2.2.15"
HotSpot VM (1.0.1fcs, mixed mode, PA2.0 build 1.2.2.15-03/05/20-PA_RISC2.0)

repeat this command with the number of versions you have as necessary

Hi Delic ,

You can install the Java from downloading form the HP site.


1. First you need to have the minimum patch level for this :

On the top of June 2004 QPK , you need to have the following patches :

PHKL_25842
PHCO_29960
PHKL_32457

Check out this link:

2. I am not sure if 1.4 Java version is there , I have installed recently Java SDK 1.3.1.16 .

And latest is Java 1.2.1.17 Sept 2005.

Here it is :

http://www.hp.com/products1/unix/java/java2/sdkrte1_3/downloads/license_sdk_1-3-1-17_pa-risc.html


3. To install:

(i) untar it .
(ii) # swinstall -s `pwd`/java_file.depot

4. Check installed version:

(i) # cd /opt/java1.3/bin
(ii)# ./java -version


Enjoy ..
Cheers,
Raj.
