Java Development on the BeagleBone Black

Get a JDK: opkg update opkg install openjdk-6-jdk Then you have all the familiar JRE and JDK tools, like java, javac, jar, etc. If you are able to install, but there is a dependency error, try to install all of the individual packages: opkg install openjdk-6-common opkg install openjdk-6-java opkg install openjdk-6-jre opkg install openjdk-6-jdk opkg install openjdk-6-vm-zero It might be that your particular distribution don't have those packages in the package list. In that case: URLs in required installation order: http://www.angstrom-distribution.org/repo/?pkgname=librhino-java http://www.angstrom-distribution.org/repo/?pkgname=openjdk-6-common http://www.angstrom-distribution.org/repo/?pkgname=openjdk-6-java http://www.angstrom-distribution.org/repo/?pkgname=openjdk-6-jre http://www.angstrom-distribution.org/repo/?pkgname=openjdk-6-jdk http://www.angstrom-distribution.org/repo/?pkgname=openjdk-6-vm-zero  Download the newest version for armv7a (or all) architecture, example:  librhino-java_1.7r2-r0_all.ipk openjdk-6-common_6b24-1.11.1+1.11.2-devel+hg1+54ceda20a02c-r17.0_armv7a.ipk openjdk-6-java_6b24-1.11.1+1.11.2-devel+hg1+54ceda20a02c-r17.0_armv7a.ipk openjdk-6-jdk_6b24-1.11.1+1.11.2-devel+hg1+54ceda20a02c-r17.0_armv7a.ipk openjdk-6-jre_6b24-1.11.1+1.11.2-devel+hg1+54ceda20a02c-r17.0_armv7a.ipk openjdk-6-vm-zero_6b24-1.11.1+1.11.2-devel+hg1+54ceda20a02c-r17.0_armv7a.ipk Install using: opkg install <filename> Test: root@beaglebone:/usr/src/javatest# cat HelloWorld.java class HelloWorld {     public static void main(String[] args) {         System.out.println("Hello World!"); // Display the string.     } } root@beaglebone:/usr/src/javatest# javac HelloWorld.java root@beaglebone:/usr/src/javatest# java HelloWorld Hello World! root@beaglebone:/usr/src/javatest#
