Eclipse and m2eclipse maven integration plugin.

I've been doing a maven course recently, and have been having heck of a job getting the m2eclipse plugin to work in eclipse (indigo java Enterprise Edition package) on Ubuntu (10.04). Every time I started the eclipse IDE I got complaints about the javahl library not being on the class path. I spent an age trying to fix this. It seems that with the install I have eclipse is not picking up the -vmargs settings from the eclipse.ini config file.
I have the java ee package of eclipse installed, and I installed it by using the package manager, and then copying the new version over the old eclipse install. I'm fairly sure this is where some of my problems are arising, because I have already found a few places in the eclipse start up scripts that reference a package directory. My Enterprise Edition (EE) package has a different path to the standard java eclipse package. At some point I will go back and clear this mess up, and fix my paths so that everything works as it should, but this quick 'hack' got me going and I can now start eclipse without a hailstorm of exception and the no javahl dialog.
In order to fix this I have installed the native svn client.

apt-get install libsvn-java
This installs the required javahl library into the /usr/lib/jni directory. However, this is not where eclipse is looking. In order to help eclipse find these libraries it is necessary to create links to the libraries in the /usr/lib directory.
sudo ln -s /usr/lib/jni/libsvnjavahl-1.so /usr/lib/libsvnjavahl-1.so
sudo ln -s /usr/lib/jni/libsvnjavahl-1.so.0 /usr/lib/libsvnjavahl-1.so.0
sudo ln -s /usr/lib/jni/libsvnjavahl-1.so.0.0 /usr/lib/libsvnjavahl-1.so.0.0
sudo ln -s /usr/lib/jni/libsvnjavahl-1.so.0.0.0 /usr/lib/libsvnjavahl-1.so.0.0.0
All being well, when you start eclipse up again, it should pick up the libsvnjavahl libraries and run like a charm.

Android logging put to bed.

I've been developing an android application recently, and I have had to scrabble around more than I should have in order to get logging working correctly so here's what I've learned. How to get logging working; The basics. Android has a Log class that you can use to make log entries. You can find that here; https://developer.android.com/reference/android/util/Log.html Here's an example of a log entry made from an Activity #import android.util.Log; class MyActivity{     private static final String TAG = "MyActivity";     @Override     protected void onCreate(Bundle savedInstanceState) {         Log.v(TAG, "savedInstanceState contains " + savedInstanceState.size() + " mappings");         ......     } } The Log.v call makes a 'verbose' log entry. Log levels (in increasing order of 'importance' are;  ...

Using an Ubuntu VM to connect to a VPN using juniper network connect.

Recently I've been using Ubuntu 12.04 running in a VirtualBox VM to connect securely to a VPN using Juniper Network connect. I've been doing this for years with a windows VM, but have recently worked out how to do it from Ubuntu. The benefits of using Ubuntu for this task are; No licensing requirements for OS. Smaller footprint for VM. - Windows 7 VM footprint was 120 MB Private Working Set. Ubuntu is as low as 70 MB Private Working Set. I haven't found any drawbacks yet. Step 1. Create an Ubuntu 12.04 LTS desktop 32bit virtualbox machine. It is important that you choose the 32 bit platform as the 64 bit version will install a 64 bit java, and juniper network connect won't work with this. If you have an existing 64 bit 12.04 install that you want to use see  here  for a work around. Step 2 Ensure openjdk-6-jdk and icedtea-6-plugin are installed by running this command from the Ubuntu VM's command line; sudo apt-get install openjdk-6-jdk ic...

The Simple Way to Create an AM Authentication Node Project

What's that all about? ForgeRock's Identity Platform Access Management introduced Authentication Trees for preview in version 5.5. Version 6.0 will see Authentication Trees and Nodes become an integral part of the product. This blog post will help you quickly and easily create a Authentication Tree Node project using Maven Archetypes. About Authentication Trees and Nodes Authentication trees provide fine-grained authentication by allowing multiple paths and decision points throughout the authentication flow. Authentication trees are made up of authentication nodes, which define actions taken during authentication, similar to authentication modules within chains. Authentication nodes are more granular than modules, with each node performing a single task such as collecting a username or making a simple decision. Unlike authentication modules, authentication nodes can have multiple outcomes rather than just success or failure. You can create complex yet customer-friendly...
