Shing Hing Man commented on TAP5-1910:
--------------------------------------
I have run into the same problem as Miguel.
I solved it by creating JpaSymbols.INITIAL_CONTEXT with default value
"java:comp/env" in JpaModule.
But not sure if it is the best approach.
The initialContext is injected into the constructor of EntityManagerSourceImpl
:
public EntityManagerSourceImpl(Logger logger,
@Symbol(JpaSymbols.PERSISTENCE_DESCRIPTOR)
final Resource persistenceDescriptor,
@Symbol(JpaSymbols.INITIAL_CONTEXT) String initialContext,
@Local PersistenceUnitConfigurer packageNamePersistenceUnitConfigurer,
Map<String, PersistenceUnitConfigurer>
configuration)
In the constructor of EntityManagerSourceImpl, the intialContext is passed to
PersistenceUnitInfo via PersistenceParser and
PersistenceContentHandler.
Then in method PersistenceUnitInto.lookupDataSource :
// initialContext is passed down from EntityManagerSourceImpl
final Context envContext = (Context) initContext.lookup(initialContext);
To set my own initialContext, I just add the following in my AppModule :
public static void contributeApplicationDefaults(
MappedConfiguration<String, String> configuration)
{
configuration.add(JpaSymbols.INITIAL_CONTEXT,"java:");
}

> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-jpa
> Affects Versions: 5.3.2
> Reporter: Miguel Figueiredo
>
> Hello,
> I am using tapestry 5.3.2 with JBoss 7, and I'm having some problems
> when using a JBoss datasource with JPA.
> My datasource configuration:
> <datasource jta="false"
> jndi-name="java:jboss/myDatasource" pool-name="mysqlDS" enabled="true"
> use-java-context="true" use-ccm="true">
> (...)
> </datasource>
> My persistence.xml configuration:
> <persistence-unit name="my-pu"
> transaction-type="RESOURCE_LOCAL">
> <provider>org.hibernate.ejb.HibernatePersistence</provider>
> <non-jta-data-source>java:jboss/myDatasource</non-jta-data-source>
> (...)
> </persistence-unit>
> Looking at the code in the PersistenceUnitInfoImpl of tapestry-jpa
> 5.3.2 I found the following:
> private DataSource lookupDataSource(final String name)
> {
> try
> {
> // TODO: Create InitialContext with environment properties?
> final Context initContext = new InitialContext();
> final Context envContext = (Context)
> initContext.lookup("java:comp/env");
> return (DataSource) envContext.lookup(name);
> } catch (final NamingException e)
> {
> throw new RuntimeException(e);
> }
> }
> In JBoss 7 the env context should be retrieved from java:jboss, e.g.:
> final Context initContext = new InitialContext();
> final Context envContext =
> (Context)initContext.lookup("java:jboss");
> return (DataSource) envContext.lookup("myDatasource");
> Maybe a datasource lookup class could be configured here.
> Best regards,
> Miguel
