java - JPA - using annotations in a model -

my application runs on jpa/hibernate, spring , wicket. i'm trying convert our orm xml files jpa annotations. annotated model looks this:

@entity @table(name = "app_user") public class user extends baseobject {     private long id;     private string firstname;     private string lastname;     private string email;      @id     @generatedvalue(strategy = generationtype.sequence)     @column(name = "id")     public long getid() {         return id;     }      public void setid(long id) {         this.id = id;     }      @column(name="first_name")     public string getfirstname() {         return firstname;     }      public void setfirstname(string firstname) {         this.firstname = firstname;     }      @column(name="last_name")     public string getlastname() {         return lastname;     }      public void setlastname(string lastname) {         this.lastname = lastname;     }      @column(name="email")     public string getemail() {         return email;     }      public void setemail(string email) {         this.email = email;     }      /**      * @return returns firstname , lastname      */     public string getfullname() {         return firstname + ' ' + lastname;     } } 

originally, though, without annotation , mapping described in user.hbm.xml:

<?xml version="1.0" encoding="utf-8"?> <!doctype hibernate-mapping public     "-//hibernate/hibernate mapping dtd 3.0//en"      "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">  <hibernate-mapping>     <class name="org.appfuse.model.user" table="app_user">         <id name="id" column="id" unsaved-value="null">             <generator class="increment"/>         </id>         <property name="firstname" column="first_name" not-null="true"/>         <property name="lastname" column="last_name" not-null="true"/>         <property name="email" column="email"/>     </class> </hibernate-mapping> 

when delete mapping file , try use annotations, entitymanagerfactory doesn't created, exception

org.hibernate.propertynotfoundexception: not find setter property fullname in class org.appfuse.model.user.

there's no mapping set property, because it's convenience method. do wrong?

mark method @transient hibernate ignore it:

/**  * @return returns firstname , lastname  */ @transient public string getfullname() {     return firstname + ' ' + lastname; } 

by default, looks getter mapped.
