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.

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.

  • 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.

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.
