fetching of data off of the user, combined with caching of that data then create a

| There are a couple of ways to do this, but the easiest is to use Seam 1.1 CVS build
and throw the following in components.xml:
|
| <component name="userDatabase"
| | scope="session"
| | class="org.jboss.seam.core.ManagedPersistenceContext">
| | <property
name="persistenceUnitJndiName">java:/myEntityManagerFactory</property>
| | </component>

| Hello, i want to use the approache mentionend above but i have some questions
regarding this.
|
| 1)
| What does "myEntityManagerFactory" means in this context, is that the value
of the "jboss.entity.manager.factory.jndi.name" property described in my
persistence.xml ?
|
|
| | <property
name="persistenceUnitJndiName">java:/myEntityManagerFactory</property>
| |
|
| 2) how can i use this(java side)?
|
| Should i use
|
| @PersistenceContext
| private EntityManager em;
|
| or (adepting your example nr1)
|
| @In(create=true)
| private EntityManager userDatabase;
|
|
| Thank u very much,
|
| Holger
