linux - Why do I need Java installed to install the JavaEE6 SDK? -


new on linux, try install javaee 6 sdk, first step install glassffish: http://www.oracle.com/technetwork/java/javaee/downloads/java-ee-sdk-6u4-jdk-7u11-downloads-1900532.html

when run

sh java_ee_sdk-6u4-jdk7-linux-x64.sh

on server, prompted should have java installed:

could not locate suitable jar utility. please ensure have java 6 or newer installed on system , accessible in path or setting java_home

this confused:

  • is java jdk package? in process of installing it, of course don't have installed yet!

  • is java jre then? should install first (and set environment variables etc.)?

thx clarification!

in order use java code, including java development kit, jdk, you'll need have java runtime environment, jre. of jdk package comes jre. jre contains api run java classes.
