Recently I came across lots of post trying to unlock why its difficult to find good Java Developers so I wanted to share my view on this topic. I've been training people on Java since 2007 for various consulting companies. First lets consider the time it takes to become an expert in PHP Development. A good php developer is expected to know these technologies (PHP, HTML, CSS, Javascript, SQL, Photoshop), and in 1 month of training he can start coding in php and in an year he will have nice grip over all these technologies. So a guy with 1yr of experience is good enough to be considered for most of the php jobs.  Now lets consider what it takes to become a good Java developer, most of the posts on job portals will look like this Java, SQL, ORM, MVC, HTML, Unit testing, Servlets, JSP, JDBC, AJAX, Design Patterns, Web Services, and IOC. Most of the students coming straight out of the college know quite a bit of Java, They write desktop and web application using very ...

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 ...

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.

Lets consider this simple Entity, Ignore @SecondaryTables and other annotations if you are not familiar with just focus on @Basic, @OneToOne, @OneToMany annotations and get ready to answer these questions. @Entity @SecondaryTables({     @SecondaryTable(name="Employee_Comments") }) public class Employee implements Serializable {     private static final long serialVersionUID = 1L;     @Id     private Long id;     @Column(name = "name")     private String name;     @Basic(fetch = FetchType.LAZY)     @Column(name = "comments", table = "Employee_Comments")     private String comments;     @OneToMany     private List tags = new ArrayList ();     @OneToOne(fetch=FetchType.LAZY)     private Address address; .. } What happens when we load the above entity using em.find or by exe...
