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#

Maybe Dave will see this and decide that blogging is "for" him, after all!

Hmmm.  All these blogging sites are a little different from one another.  Here in Google-territory, the creation of a new post presents you with a blank editing screen -- and no context within which to compose.  Elsewhere, it's more Wiki-like, and you simply insert text below (or above, if that's how you roll) all prior entries.

No matter.  They all work, and after some floundering perhaps I'll settle on a single one.

So: One needs to type "+" followed by the correct case of the first name "T" or "T" -- although in my own case, "t" also works but not for Carolyn.  I'm not sure I understand it fully, but at least I know the secret now. +David Maynard +Martha Patterson ... just like that!

[01/11/2013 @ 09:18] I have invited @Carolyn Maynard to the +Trifluent blog here.  Only time will tell if she accepts the invitation.
