Insert code into your Blogger posts

Programmers know that blogger doesn't support code insertion (usefull if you need to demonstrate how to program something by copy/pasting code samples). Thus, you need to swicth  Blogger's editor to HTML and paste HTMLized text.

The nicest solution I found to format your code to HTML is to use this online code formatter : http://hilite.me/

So, let's show an example:

How to secure REST services exposed with Jersey (JAX-RS) using Spring Security

This is the challenge I had to perform. I have to open services to business partners and I want to secure them. I use a Java based application with Jersey API (JAX-RS).

The first thing to consider is : what kind of solution offers the best compromise between security and the effort I'll have to provide to maintain this solution?
After some discussions with developers and experts, the conclusion is : expose your services over https and use Basic authentication (Digest authentication and certificate based authentication are too complex for partners)

So, how to implement that? I delegate "https" to my Apache http servers. But I still need to handle authentication (and authorization of course). After long hours on Google, I understood that it is possible to manage security with Jersey by many many ways. Here is a short list :

Delegate simple authentication and authorization to your container (Tomcat) or to your frontend (Apache)Delegate authentication to your container or fro…
