Gmail or Google Apps as Liferay SMTP Server

Good thing of this approach is you don't need restart compare to setting inside ROOT.xml or portal-ext.properties

Go to

Control Panel --> Server Administration --> Mail

and enter these values

Note : If you don't see emails coming, enable your pop of your gmail account.

JPA 2 new feature @ElementCollection explained

@ElementCollection is new annotation introduced in JPA 2.0, This will help us get rid of One-Many and Many-One shitty syntax. Example 1: Stores list of Strings in an Entity @Entity public class Users implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @ElementCollection private List<String> certifications = new ArrayList <String> (); public Long getId() { return id; } public void setId(Long id) { this.id = id; } public List <String> getCertifications() { return certifications; } public void setCertifications(List <String> certifications) { this.certifications = certifications; } .. } Users u = new Users(); u.getCertifications().add("Sun Certified Java Programmer"); em.persist(u); Generated Tables Users Co

Validating CSV Files

What is CsvValidator ? A Java framework which validates any CSV files something similar to XML validation using XSD. Why should I use this ? You don't have to use this and in fact its easy to write something your own and also checkout its source code for reference. Why did I write this ? Some of our projects integrate with third party application which exchanges information in CSV files so I thought of writing a generic validator which can be hooked in multiple projects or can be used by QA for integration testing. What is the license clause ? GNU GPL v2 Are there any JUnit test cases for me checkout ? Yes, source How to integrate in my existing project ? Just add the Jar which can be downloaded from here CsvValidator.jar and you are good. Instantiate CsvValidator c onstructor which takes these 3 arguements // filename is the the file to be validated and here is a sample // list - defines all the fields in the above csv file ( a

Reuse JPA Entities as DTO

Note : Major design advantages of JPA Entities are they can detached and used across tiers and networks and later can by merged. Checkout this new way of querying entities in JPA 2.0 String ql = " SELECT new prepclass2.Employee (e.firstname, e.lastname) FROM Employee e "; List<Employee> dtos = em.createQuery(ql).getResultList(); The above query loads all Employee entities but with subset of data i.e. firstname, lastname. Employee entity looks like this. @Entity @Table(name="emp") public class Employee implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @Column private String firstname; @Column private String lastname; @Column private String username; @Column private String street; @Column private String city; @Column private String state; @Column private String zipc
