Installing a Java Development Environment

The |sdk-java| requires J2SE Development Kit 6.0 or later. You can download the latest Java software from http://developers.sun.com/downloads/.

Important

Java version 1.6 (JS2E 6.0) did not have built-in support for SHA256-signed SSL certificates, which are required for all HTTPS connections with AWS after September 30, 2015. For more information, see :doc:`use-sha256`.

Java versions 1.7 or newer are packaged with updated certificates and are unaffected by this issue.

Choosing a JVM

For the best performance of your server-based applications with the AWS SDK for Java, we recommend that you use the 64-bit version of the Java Virtual Machine (JVM). This JVM runs only in server mode, even if you specify the -Client option at run time.

Using the 32-bit version of the JVM with the -Server option at run time should provide comparable performance to the 64-bit JVM.
