"Cannot locate suitable jar utility" while trying to install Oracle Java JDK

Question

I have installed jdk-7u3-linux-i586.tar.gz according to this:

How do I install Oracle Java JDK 7?

But when I try to install java_ee_sdk-6u4-unix.sh using the command sudo sh java_ee_sdk-6u4-unix.sh from inside the /home//Downloads/ directory I get the message

Could not locate a suitable jar utility. Please ensure that you have Java 6 or newer installed on your system and accessible in your PATH or by setting JAVA_HOME

Note: Even though I get the mesage "Could not locate a suitable jar utility. Please ensure that you have Java 6 or newer installed on your system and accessible in your PATH or by setting JAVA_HOME" commands "java", "javac" are working from any location.

Answer 1

The problem is the same that for other programs (java, javac, javaws etc.) You just need to create an update alternative for the "jar" program like this:

sudo update-alternatives --install "/usr/bin/jar" "jar" "/usr/lib/jvm/jdk1.7.0/bin/jar" 1

Note: remember to replace the "jdk1.7.0" path by the real name of your target jdk installation path if it is different.

Answer 2

• Download the .tar.gz package from here.
• Unzip it to a location ( say ~/java/ )
• run

   update-alternatives --install "/usr/bin/java" "java" 

  ( Assuming that you have update-alternatives installed already. You should, if you you openjdk installed.)

Those steps should make java available globally.

Answer 3

The quick-and-dirty solution:

At the command prompt type:

sudo apt-get install jarwrapper fastjar

Now, when you run ./java_ee_sdk-6u4-unix.sh again, it should install without a hitch.
