why is jar command not found?

s0450776 · 06-27-2005, 09:57 AM

hi

i installed java runtime environment and java media framework in order to run video annotation software. The annotation software download requires unpack of .zip file using JAR. When i try using JAR command it said:

bash: jar: command not found

I tried also installing jdk package but i still get the same response. I tried find jar and got:

find: jar: No such file or directory

I am puzzled but a total newbie so it could be anything.

Any help would be greatly appreciated

Ps. i rebooted after installation and use mandrake 10.1

tell me how do you install the java runtime and its media framework???

sorry, can't remeber exactly, but followed the instructions at java.sun...
i downloaded to home directory and then,

for jre:

chmod a+x jre-1_5_0_<version>-linux-i586-rpm.bin

./jre-1_5_0_<version>-linux-i586-rpm.bin

for jmf:
/bin/sh ./jmf-2_1_1e-linux-i586.bin

for jdk :
chmod a+x jdk-1_5_0_<version>-linux-i586-rpm.bin
./jdk-1_5_0_<version>-linux-i586-rpm.bin
rpm -iv jdk-1_5_0_04-linux-i586.rpm

Apologies for not being clearer - don't really know what i am doing

You might need to add the directory with jar in it to your $PATH, you can do this through /etc/profile or through your ~/.bashrc with

Code:

export PATH = $PATH:/path/to/jar/directory

this is really stupid, but does that mean navigate to /etc/profile and execute the command? i tried to navigate to /etc/profile but it is not a directory - there is a profile.d.

i also tried ~/.bashrc but got

bash: /root/.bashrc: Permission denied

(i logged on as root with password but got the same)

thanks

You installed java sdk, but previously you installed java runtime. Why???? Java sdk has already java runtime. Try to log as normal user then run jar command.

~/.bashrc is a file that gets sourced when you start up a bash shell. So if you edit it, you should be able to find a line in it somewhere that is adding to the PATH. If not, you can just add a line like:

Code:

PATH=$PATH:/usr/local/bin/

Or wherever jar is located on your system. On my system, it is /usr/bin/jar, but I guess yours was installed somewhere else.

i suggest you don't use the root account for usual stuff. As root put this in the file /etc/profile

JAVA_HOME=/usr/java/jdk_directory
export JAVA_HOME

PATH=$JAVA_HOME/bin:$PATH
export PATH

thanks for the help first i tried entering root and editing .bashrc with winscp and adding the line
export PATH = $PATH:/opt/jdk-6u26/bin
and then saving the file but it didn't work but then i just typed in command prompt
export PATH = $PATH:/opt/jdk-6u26/bin and got the error
-bash: export: `=': not a valid identifier
so i removed the spaces and it worked (export PATH=$PATH:/opt/jdk-6u26/bin)

although i am bewildered as i followed all the instructions when installing the java development rootkit and one of the final instructions was to export some paths.

Hello
I'm trying to build android system following this tutorial http://code.google.com/p/seek-for-an...ngTheSystemand I installed the jdk6 from the sun web site
I'm on ubuntu 11.10
When I run make update-api I have this error : host Java: jsr305lib (out/host/common/obj/JAVA_LIBRARIES/jsr305lib_intermediates/classes)
/bin/bash: jar : commande introuvable
make: *** [out/host/common/obj/JAVA_LIBRARIES/jsr305lib_intermediates/javalib.jar] Erreur 127.
I don't find any solution on internet.
Please can someone help me.

You may have no JDK installed, or your jdk/bin directory is not on the PATH
For example in my system:

Code:

/opt/jdk1.6.0_21/ -- here is JDK installed
/opt/jdk -> symlink to jdk1.6.0_21

/etc/profile contains these lines:

export JAVA_HOME=/opt/jdk
export "PATH=$PATH:$JAVA_HOME/bin"

So you should check if JDK is installed, where is it installed, and how could you add its 'bin' directory to the PATH.

Hi Simo_s,

Looks like you already install jdk manually, is may be that jar is not registered in your java path.

you can do the following simbol link,

sudo update-alternatives --install "/usr/bin/jar" "jar" "/usr/lib/jvm/jdk1.6.0/bin/jar" 1

You can change "/usr/lib/jvm/jdk1.6.0" to your jdk install directory.

finally run jar to see if it is working, then continue build
