You must have a way to transfer files from the host to the target, such as a network connection or memory card.

2.1 Host Requirements

The host is any x86 personal computer running Linux and the Java SE Developer's Kit (JDK) version 1.7 (any update). You can download the JDK (and optionally the NetBeans IDE) from

To build the sample applications described in the Application Developer's Guide, or your own application that is based on a sample, you need the following:

2.2 Target Requirements

This release supports ARM- and x86-based target devices running a Linux operating system.

2.2.1 ARM Target Requirements

The following table specifies the requirements for ARM target devices. The software is compiled for compatibility with ARM V6 and V7, and does not exploit the potential performance advantages of V7.

Requirement Description


ARM V6 and V7

Floating Point



64MB or more


66MB or more

Operating System

Linux kernel 2.6.28 or higher; glibc 2.9 or higher

2.2.2 x86 Target Requirements

The following table specifies the requirements for x86 target devices.

Requirement Description




64MB or more


66MB or more

Operating System

Linux kernel 2.6.28 or higher; glibc 2.9 or higher

2.3 Testing Notes

For ARM targets, the principal test platform was V7-based. Basic "sanity" tests were run on a V6 target.

The largest database used for Java DB testing was 32GB.

3 Documentation

In addition to these Release Notes, the Oracle Java Embedded Suite documentation set includes the Oracle Java Embedded Suite Application Developer's Guide.

4 Installation Instructions

For installation instructions, refer to the Application Developer's Guide.

5 Known Problems and Issues
