Overview

We can obtain the latest Liberty profile package from the WASdev community website

The Liberty profile requires a JRE to run in. By default, it does not share the JRE with the WAS, so specify the JRE location. By default, JVM on the system PATH is used by default. To verify from cygwin shell that PATH has JVM location...

env | grep ^PATH

Another way to discover JVM......

$ E:/IBM/Worklight/server/wlp/bin/server version worklightServer
WebSphere Application Server wlp-1.0.1.cl0120121004-1949(websphere-kernel_1.0.1) on Java HotSpot(TM) Client VM, version 1.7.0_06-b24

For WAS version info...

$ cd E:/IBM/Worklight/server/wlp/bin
$ ./productInfo.bat version
Product name: WebSphere Application Server
Product version: 8.5.0.1

Minimum supported level for the IBM JDK is 6.0 (J9 2.6) SR1. Minimum supported version of JDK from Oracle is Java 6 update 26. On distributed platforms, 32 and 64-bit Java is supported.

On the Macintosh OSX operating system, Apple Java SDK 6.0 and future releases, mod levels and fix packs are supported.

Set JRE in PATH

To set JRE in PATH on Windows 2008 R2....

Start | Control Panel | System and Security | System | Advanced system settings | Environment Variables

To set via command-line (Start | Run | cmd):

set JAVA_HOME=C:/IBM/jre6
set PATH=%JAVA_HOME%/bin;%PATH%

Settings are only valid in the command prompt window that you are currently in (or shell if you are on UNIX).

The Liberty profile runtime searches for the java command in the following order of properties:

JAVA_HOME, JRE_HOME, PATH

Additionally, we can set up a specified Java Runtime by editing... E:/IBM/Worklight/server/wlp/etc/server.env

...and setting...

JAVA_HOME=C:/IBM/jre6

If the file does not exist, create it manually in the Liberty profile etc directory.
