Ubuntu 11.04 jar command

brownie_cookie · 09-09-2011, 02:25 AM

Hi all

I'm not new here, but Ubuntu is new to me

so here i am..
I'm trying to execute the JAR command to update a jar file.

Code:

jar uf $loc/bin/jar/jinnyintegrator.jar $loc/bin/jar/config.properties

When i execute this script i get the message that jar isn't found.
Even when I do

Code:

which java

i get things i shouldn't get

so i know that java (or jar?) isn't installed appearently (something like openjdk is installed, but i don't know if that matters..?)
So can someone give me the right commands for succesfully install Java (or jar) on Ubuntu 11.04?
It's highly appreciated!

okay, i've found it, normally jar should work (which jar works so...)
but i want to update a jar file, but it isn't working..

this is what i do:

Code:

touch $loc/bin/jar/config.properties
	chmod 755 $loc/bin/jar/config.properties
	echo "# the time properties are expressed in minutes!" >> $loc/bin/jar/config.properties
	echo "filters.enabled=true" >> $loc/bin/jar/config.properties
	echo "filters.max_time=$Max_time" >> $loc/bin/jar/config.properties
	echo "filters.max_programs=$Max_progs" >> $loc/bin/jar/config.properties
	echo "filters.min_percentage=$Min_per" >> $loc/bin/jar/config.properties
	echo "filters.min_time=$Min_time" >> $loc/bin/jar/config.properties
	echo "" >> $loc/bin/jar/config.properties
	echo "# add the time viewed to a specific channel" >> $loc/bin/jar/config.properties
	echo "viewingrecordcorrelation.enabled=true" >> $loc/bin/jar/config.properties
	echo "tekst toegevoegd"
	
	# Zip the application
	echo "alles zippen"
	jar uf $loc/bin/jar/jinnyintegrator.jar $loc/bin/jar/config.properties

am i doing something wrong ??

Thanks for the help

In my jre I need to use

Code:

java -jar <jar file>

for running a jar file. Have you tried that?

yeah, i know how to execute a jar file, but i want to update my jar file

Man pages:

Code:

Update jar file
          jar u[v0Mmfe] [manifest] [jarfile] [entrypoint] [-C dir] inputfiles [-Joption]

So i do:

Code:

jar uf $loc/bin/jar/jinnyintegrator.jar $loc/bin/jar/config.properties

but the file he must update, doesn't update

Installing "sun-java6-jdk" on Ubuntu 11.04 :

Sorry, now I get it.

Code:

jdkaye@AttilaII:~$ which jar
/usr/bin/jar

As you said, it looks like your java is not installed correctly.
I don't see any debian package that has /usr/bin/jar. Maybe you should download the jdk from Oracle *vomit noises*.

which jar
/usr/bin/jar

ls -l /usr/bin/jar
lrwxrwxrwx 1 root root 21 16 aug 2009 /usr/bin/jar -> /etc/alternatives/jar

ls -l /etc/alternatives/jar
lrwxrwxrwx 1 root root 33 13 dec 2009 /etc/alternatives/jar -> /usr/lib/jvm/java-gcj/jre/bin/jar

But if the command 'java -jar' is used, it's not really a problem,
that "alternatives" use a link to the wrong java version ( java-gcj ) :

java -version
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)
→ → → This is the sun-java6-jdk.

Code:

# update-alternatives --config java
-----------------------------------------------
          1    /usr/bin/gij-4.3
 +        2    /usr/lib/jvm/java-gcj/jre/bin/java
*         3    /usr/lib/jvm/java-6-sun/jre/bin/java

The above is from Debian Lenny.

To the OP : The Ubuntu package should be preferred. See post # 5.

okay, first of all, thank you all for the replies !!

I tried the website provided in post # 5
The first few steps worked:

Code:

sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update

but then to install java, it failed:

Code:

# sudo apt-get install sun-java6-jre sun-java6-jre-plugin
Pakketlijsten worden ingelezen... DONE
Boom van vereisten wordt opgebouwd       
De status informatie wordt gelezen... DONE
E: Kan pakket sun-java6-jre-plugin niet vinden

i know it is in dutch, but in the last (see bold) it says it cannot find the plugin

any ideas?

brownie_cookie · 09-09-2011, 07:23 AM

maybe some nice things to know...

Code:

#which jar
/usr/bin/jar

#which java
/usr/bin/java

# java version
Exception in thread "main" java.lang.NoClassDefFoundError: version
Caused by: java.lang.ClassNotFoundException: version
	at java.net.URLClassLoader$1.run(URLClassLoader.java:217)
	at java.security.AccessController.doPrivileged(Native Method)
	at java.net.URLClassLoader.findClass(URLClassLoader.java:205)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:321)
	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
Could not find the main class: version. Program will exit.

Also the website of post 5, i did all the commands seperatly and i did not install the plugin because that one gave an error, but the rest is installed.
Can someone explain why i can locate the place where java is installed but when i try to execute it (version) that it fails?

thanks

There is no command : java version

The command is : java -version
( You forgot the hyphen ( - ).

And : Those command should not be run as root.
Root is for administrative tasks only.
Running as root is the fastest way to trash your OS.
+ Makes things unsafe for everybody on the internet, if you are connected.

Just do be sure, does this mean you've sorted out your problem?

damn, true, forgot it!!

sorry guys

Code:

# java -version
java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.2) (6b22-1.10.2-0ubuntu1~11.04.1)
OpenJDK Client VM (build 20.0-b11, mixed mode, sharing)

and i see your point of the root problem, but i don't put anything online, it's just for testing

and i'm working in a virtual environment so if any goes wrong -> reinstall -> done

(but still i know it's probably not the best way to do it, but that is not the issue)

but let's recap
the issue of java is solved, but the problem with the jar command isn't..
So i want to update a jarfile with a file i create.
I create and update the jarfile in the same script, is that the problem?

Thanks in advance guys
