rohaanembedded · 07-02-2013, 02:36 AM

Dear sir,

i want to find out the active java configuration on ubuntu machine and go to that folder and install jai-1_1_3-lib-linux-i586-jdk.bin

i have tried script like,

Code:

#!/bin/bash

cd /usr/lib/jvm/java-*-openjdk/


cp /home/usb/jai/jai-1_1_3-lib-linux-i586-jdk.bin .


chmod 777 jai-1_1_3-lib-linux-i586-jdk.bin	


./jai-1_1_3-lib-linux-i586-jdk.bin

but it doesnt really install the .bin in active Java JDK on machin

to find out the active configuration there is a command also

Code:

sudo update-alternatives --config java

which gives

Code:

There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                      Priority   Status
------------------------------------------------------------
* 0            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      auto mode
  1            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      manual mode
  2            /usr/lib/jvm/jdk1.7.0/bin/java             1         manual mode

Press enter to keep the current choice[*], or type selection number: 0

i dont want to change the active java JDK confg but just want to go to that folder and install my .bin there.

please help me in this please

Thanks & Regards

Hi,

I don't recommend manually putting files under /usr/lib, but you can find the location of the default java with something quick and dirty like:

Code:

readlink -f $(which java)

Or using update alternatives:

Code:

update-alternatives --list java

Dear sir,

Code:

readlink -f $(which java)

gives output like

Code:

/usr/lib/jvm/java-6-openjdk/jre/bin/java

how can use this path to go to the location in /usr/lib/jvm/java-6-openjdk/
how to catch the output of the above command while using it in shell script like

Code:

#!/bin/bash

readlink -f $(which java)

Hi,

this is marked as solved now, and I wonder what your solution was. Did you learn how to set variables in a shell script?

Regardless I don't know why you are trying to manually dump that file in that particular location. If you want to install the java imaging api you should probably be using your package manager.

Eg

Code:

sudo apt-get install libjai-core-java

Dear sir

thanks for rply i find out how we can use that PATH getting from the readlink -f $(which java)
and used that path in my script and done with the thing
Actually i want it because as i told u i want to give this thing to the another users which may no have net or they should not have to do this apt-get bcz this has to be a part of my application which uses jai as library

thanks again really thanks

Ok, then you can bundle the jai .deb file and have your script install it using "dpkg -i". Anything is better than just dumping the .bin file in is /usr/lib/.

Hi,

don't use the .jar or .bin files, instead download and use the .deb file from the Ubuntu repository.
See for example http://packages.ubuntu.com/search?keywords=libjai

Dear sir

Your perfectly right in approach but its size is around 5MB for each file libjai-core-java i have to give it with my package so i think it will be better to use this jai-1_1_3-lib-linux-i586-jdk.bin which includes all the functionality of two files sun-java_core.jar and sun-java_codec.jar and its size is also lesser around 3.5MB

Thanking you

Hi,

did you check licence in regards to redistributing Sun/Oracle Java? I checked the FAQ https://www.java.com/en/download/faq/distribution.xml and it seems you are supposed to abide by the "Oracle Binary Code License" http://www.oracle.com/technetwork/ja...nse/index.html if redistributing their software.

Oracle is a pretty scary company.

Anyway, good luck.
