Maven is a powerful yet complex tool. When I started learning Maven, the first obstacle was, of course, its complexity. The second, was the lack of documentation that can get me off the ground quickly. This tutorial is an attempt to create a pragmatic guide that aims to get you familiar with Maven in the quickest way possible. The main theme is to get you on some hands on experience to start out and lead you through the creation of a simple Java EE project as quickly as possible. Instead of trying to give you a good read, I try to get you on the journey right away. The topics are roughly ordered by the logical sequence but you can jump around in any way...

For some reason I don't know writing to files in Android is very complicated and tedious. Here is some code for those who might need it.

For Tomcat 6, there's no default manager username and password. You do have to set it up yourself, though it's pretty straightforward. The Tomcat manager webapp is restricted to users with a role named manager . So you'll need to create a user and assign the manager role to it. Edit $CATALINA_BASE/conf/tomcat-users.xml to read: <?xml version='1.0' encoding='utf-8'?> <!-- ... For tomcat 7: <tomcat-users> <role rolename="manager"/> ...

Alfresco RESTful URLs provided by Web Scripts are extensively documented, but examples are hard to come by. This makes it hard to ramp up for beginners. Here are some examples I tested on 3.4.4 enterprise edition and 4.0a community edition, with the results documented. To list the available scripts: http://localhost:8081/alfresco/service/index There's a Refresh Web Scripts button at the bottom of the page. If you add a Web Script, you need to click that button in order for the system to know about your addition. To get information about the root folder ( Company Home ): http://localhost:8081/alfresco/service/cmis/p To get information about the folder Data Dictionary : http://localhost:8081/alfresco/service/cmis/p/Data...
