I used the procedure to upload the artifacts to Sonatype Nexus.

Visualize data and execution

The blog post http://worrydream.com/LearnableProgramming/ has an amazing introduction on how a learning environment can show a budding developer the state and execution of a piece of code.

Duinsoft makes installing Oracle Java 7 easy on Linux Mint 13

I needed Oracle’s version of Java 7 so that I can develop with the JetBrains WebStorm IDE on my Mint Linux 13 box, and I found that the folks over at Duinsoft have made it real easy to do this.

The basic steps are:-

• put the line
  deb http://www.duinsoft.nl/pkg debs all
  in the file /etc/apt/sources.list, either using Software Sources from your System Menu or by editing the file in an editor (as root)
  or:
  put this line in a file named (e.g.) duinsoft.list in the directory /etc/apt/sources.list.d
• import the gpg key with the command (all on one line)
  sudo apt-key adv –keyserver keys.gnupg.net –recv-keys 5CB26B26
• enter the commands (two lines)
  sudo apt-get update
  sudo apt-get install update-sun-jre
  or use Synaptic to install the package

installation of the Runtime Environment will follow automatically

The page at Duinsoft details how to more control of the installation process.

Installing Apache Karaf features behind a firewall

Apache Karaf can either use :-

• the proxy settings in the Maven settings.xml in the specific user’s .m2 directory running the Karaf instance
• the proxy settings in the global settings.xml in the conf directory of the Maven installation
• the mvn repository can be changed within Karaf to include a local Maven repository like Sonatype Nexus

To use the settings.xml file, specify the following in the file in the global conf directory or in the user’s .m2 directory.

<proxies>
<proxy>
<id>optional</id>
<active>true</active>
<protocol>http</protocol>
<username>username</username>
<password>password*</password>
<host>hostname or ip</host>
<port>port</port>
<nonProxyHosts>localhost|127.0.0.1|10.0.0.3|10.0.0.4</nonProxyHosts>
</proxy>
</proxies>

The approach that I prefer is to add the Sonatype Nexus public url to the list of repositories that Apache Karaf should use when resolving features. This allows all the developers in a team to utilize the same shared resource for resolving artifacts. Open the ${karaf install folder}\etc\org.ops4j.pax.url.mvn.cfg file and add the url to the org.ops4j.pax.url.mvn.repositories config item.

org.ops4j.pax.url.mvn.repositories= \
http://localhost:9091/nexus/content/groups/public, \
http://repo1.maven.org/maven2@id=central, \
http://repository.apache.org/content/groups/snapshots-group@id=apache@snapshots@noreleases, \
https://oss.sonatype.org/content/repositories/ops4j-snapshots@id=ops4j.sonatype.snapshots.deploy@snapshots@noreleases, \
file:${karaf.home}/${karaf.default.repository}@id=systemrepo, \
file:${karaf.data}/kar@id=karrepos@multi
