How to run a Java / .jar file automatically?

English Applications
#1

Hi Everyone! I need some help.

I just downloaded a program called Oulook Messenger that my family uses to communicate. The program uses Java to run on Linux machines and I would like it to start automatically with my computer. I can run it by going to to folder, opening the terminal there, and typing in:

java -jar OutlookMessenger.jar

However when I close the terminal, Outlook Messenger closes too. Is there a way to open this when my computer starts without having the terminal open? Thanks!

Well the first idea might be that you post the error message you got?

You forhot to tell:
a) which level of openSUSE you use;
b) which desktop you use.

When you say " when my computer starts", do you mean on boot (thus without anybody loged in), or on login of a certain user. In the first case it is a system thing (should go in boot.local or the like), for the second case it should go into the autostart of the user’s desktop.

press alt+f2 and then type in java -jar /home/<fullpath>/abc.jar

You are so right! Sorry about that. I just installed openSUSE last night, so I am kinda new to it :slight_smile:

I am running openSUSE 12.2 with KDE 4.9.5.

So if I go into the autostart, (Not really sure where that is) and choose it to start, will it start like it should with java, or just the archive manager?

Specific error message would be helpful.

If you get it working, from a terminal you can run it in the background
with:

java -jar <jarfile.jar> &

Then when you close the window, the app will continue to run.

The proprietary java has something called jexec that does exactly this. I’m sure there might be something in the open source world as well.

They don’t even package oracle / sun java due to licensing issue. You can forget about FUDware :slight_smile:

Well, you can not get oracle/sun java from openSUSE via yast or zypper
as we did in the past, but of course that you can download and install
it if you want it.

The license issue simply impedes distributors from distributing it. It
is a silly move, IMO, but they are very happy if you download it from
them directly and install it.

The main problem with doing it from sun/oracle download is that , we need to do those syslink tricks for browsers to detect in case we need applets etc… Not a very pleasant process per se :slight_smile:

Java in the browser has been disabled by me for a very very long time due to the absolute security mess it is. But yeah, install the proprietary version isn’t straightforward at all.All I was saying is that the Oracle version has something that allows for what the OP wanted and I’m sure there is an open source equivalency.

It is not that difficult. You do it once, and after that you simply
upgrade the rpm each time.

There seems to be some problem here. The OP didn’t say " when my
computer starts"! Is this some bug in the forum/nntp software?

this question should be in the appropriate forum, but i’ll answer
here and a mod can decided to move this sub-thread if they wish:

yes and no!

it is a bug in that the forum/nntp hookup allows the text to flow to
the nntp side while the http user is still in the process of editing
the post…

no it is not be a ‘bug’ because it has been that way for years and
won’t be changed because the http user must (apparently) be able to
press Post and still change text for some seconds/minutes…

because delivering complete/correct posts to the nntp side is
secondary…everything to do with the nntp side is secondary.

Thanks for all the advice guys. :slight_smile:

I am using OpenJDK

So I open the terminal up where my .jar file is, and type this:

java -jar OutlookMessenger.jar

Outlook Messenger then opens, but I have to keep the terminal open too. Is there a way to open Outlook Messenger without using the terminal so that when I double click on the file it just opens? I found the way to make it startup in Linux Mint KDE automatically, but it still doesn’t work in openSUSE, because I need to have the correct application in the “Application Preference Order”.

You can, for example, press alt-f2, that usually opens a small dialog to
type a command, and type your text in there. It usually has an history
to retrieve what you typed yesterday.

Desktops usually also have methods to create icons so that when you
click on them the run whatever you want. I do not normally use that
method and I don’t know what desktop you use, so I will not give more
details.

Hi
Just create a script (eg called start_OutlookMessenger) to run it from
you home bin directory and background it


#!/bin/bash
cd /some/path/to/your/jar/file
/usr/bin/java -jar OutlookMessenger.jar &

Then make it executable;


chmod 700 ~/bin/start_OutlookMessenger
start_OutlookMessenger
