java jre issue

English Applications
#1

I upgraded this machine from using jre-6u37 to jre-7u17 (oracle). A java
program I need starts and runs well, it appears. However, I wanted to
check the java version, and got this:


cer@Telcontar:~> java --help
Unrecognized option: --help
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
cer@Telcontar:

Does it simply mean that the “–help” or “–version” options are not
recognized, or do I have something else missing?

java does not follow the GNU style for options, you have to call it with


java -version
java -help

only one minus sign.

one “-” as Martin says…which here gives


denverd@linux-os114:~> java -version
java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b06)

you can also test the browser part at
http://java.com/en/download/installed.jsp

which here tells my 11.4 evergreen has “Java version: Version 7
Update 5” and

so, did you put update 7 on your 11.4?? and how? (that is, did you
use yast to install the rpm, or rpm command at the CLI? and did the
oracle instructions work alright

How obvious. Once you know… or remember.

That’s on 12.1, later I can test in 11.4. I have to go out.

you can also test the browser part at
http://java.com/en/download/installed.jsp

which here tells my 11.4 evergreen has “Java version: Version 7 Update
5” and

Completion checkmark
Congratulations!
You have the recommended Java installed (Version 7 Update 17).

so, did you put update 7 on your 11.4?? and how? (that is, did you use
yast to install the rpm, or rpm command at the CLI? and did the oracle
instructions work alright
[http://java.com/en/download/help/linux_install.xml])

I did not even read the instructions, or I forgot them :slight_smile:

I simply downloaded the 64 bit rpm, and run “rpm --upgrade packagename”
on it as root, that’s all. Of course, I already had the 1.6 rpm
installed, also from Oracle, so I did not have to change anything,
worked out of the box.

(and I tried first in my 11.4 box - java is not that crucial for me in
there)

Actually, I once followed the link at:


https://sites.google.com/site/easylinuxtipsproject/java-for-opensuse
http://java.com/en/download/manual_v6.jsp

but instead of using the bin package it recommends, I went for the rpm.
It is much easier to upgrade to the next version once you install the
first one.

So, exactly the same - not surprising, I used the same rpm :slight_smile:
