Re: [T5]: Hibernate question - session is null
Is the hibernate service initialized at all?

I see no output about Hibernate at all. It never gets mentioned...

Also perhaps use org.hibernate.dialect.MySQLInnoDBDialect to support foreign keys? (Change to hibernate config.) You should be able to see that Hibernate starts in the logs and maps User etc. classes. Remember to configure your Log4J or what ever logging u use to debug. I added some lines to log4j.properties to turn on hibernate logging (debug), but I see no output - just the usual Tapestry debug output that I've seen before. I'm really stumped... :-( Hibernate never gets called and yet everything appears to be in place. p. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- View this message in context: http://www.nabble.com/-T5-%3A-Hibernate-question-tp18634071p18684648.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Check also that you have the mysql-connector-java-5.1.6.jar or similar in your libraries.

Re: [T5]: Hibernate question - session is null
Yep, Injection works only in page and component classes that live the
ordinary Page or component lifecycle, and are requested from the web. :)
Move the session to a real page and have that util to take the session as
parameter, or even better move your logic to service that a page can use.
(SecurityService perhaps?)

Re: [T5]: Hibernate question - session is null
Hi,
I also had some trouble configuring hibernate, my session was also null.
After searching for a while I found this tutorial:
http://linuxboy.javaeye.com/blog/68311
Since I dont use a DAO, my code looks something like the following.
my db entity:
...
import org.hibernate.Session;
@Entity
@Table(name = EVENT)
public class EventDBEntity {
public EventDBEntity() {}
public EventDBEntity(Session session) {_session = session;}
@Transient
private Session _session;
// more stuff here.. methods to access the db
...
in my appmodule.java:
...
public static void bind(ServiceBinder binder)
{
binder.bind(TourDBEntity.class);
}
...
then I call an @Inject on the db-entity:
...
// db entity object
@Inject
private EventDBEntity _dbEntity;
// now tapestry injects the hibernate session in my _dbEntity
...
Hope this helps!
Greetings, Mark

Re: [T5]: Hibernate question - session is null
Tapestry should be quite verbose about hibernate if tapestry is configured to
run in debug mode:
http://tapestry.apache.org/tapestry5/tapestry-core/guide/conf.html
add:
//This is the time in seconds that Tapestry waits before checking if a file
is modified
//Use a big number in production to imporve perfomance.
configuration.add(SymbolConstants.FILE_CHECK_INTERVAL, 1 s); //
600 to production!
// The factory default is true but during the early stages of an
application
// overriding to false is a good idea. In addition, this is often
overridden
// on the command line as -Dtapestry.production-mode=false
configuration.add(SymbolConstants.PRODUCTION_MODE, false);
to your AppModule.java's public static void
contributeApplicationDefaults(MappedConfigurationString, String
configuration) { method.
Also see that your entities are in correct place (same root package as pages
and components, in entities package.)
Also perhaps use org.hibernate.dialect.MySQLInnoDBDialect to support foreign
keys? (Change to hibernate config.)
You should be able to see that Hibernate starts in the logs and maps User
etc. classes.
Remember to configure your Log4J or what ever logging u use to debug.

Re: [T5]: Hibernate question - session is null
And of course, check that you have Hibernate and hibernate annotation in your libraries, they are NOT included automatically by maven if maven is used. - 99 photos-4 wrote: I'm using Eclipse.

Check that the
@Inject
private Session session;
session is org.hibernate.Session.

It is. I notice that when I switch on the mysql log that no attempt
is ever made to
access the db. Is there any kind of logging I can switch on from
Tapestry (or maybe
Hibernate) to tell me what is going on? (I am quite sure the xml file
is correct and in
the classpath, so I am running out of ideas! Although it must be
something simple as
these things usually are). session is always null when this code is run.
Code and XML below:
package uk.bl.dlportal.pages.util;
import java.util.List;
import org.apache.tapestry5.ioc.annotations.Inject;
import org.hibernate.Query;
import org.hibernate.Session;
import uk.bl.dlportal.entities.User;
public class Security
{
@Inject
private Session session;
private final static Security security = new Security();
public User authenticate(String userName, String password)
{
System.out.println(SESSION
+session);
List result = session.createCriteria(User.class).list();
return null;
}
public static Security getSecurity()
{
return security;
}
}

Re: [T5]: Hibernate question - session is null
Thanks for your help, but so far no joy: Quoting 9902468 [EMAIL PROTECTED]: And of course, check that you have Hibernate and hibernate annotation in your libraries, they are NOT included automatically by maven if maven is used. The libraries appear in my repository and appear under sources in the Eclipse Run Configuration. Tapestry should be quite verbose about hibernate if tapestry is configured to run in debug mode: http://tapestry.apache.org/tapestry5/tapestry-core/guide/conf.html add: I placed -Dtapestry.production-mode=false on the command line, which, according to the docs, does the same thing. I see no output about Hibernate at all. It never gets mentioned... Also see that your entities are in correct place (same root package as pages and components, in entities package.) src/main/java/uk.bl.dlportal.entities src/main/java/uk.bl.dlportal.components src/main/java/uk.bl.dlportal.pages looks ok to me. Also perhaps use org.hibernate.dialect.MySQLInnoDBDialect to support foreign keys? (Change to hibernate config.) You should be able to see that Hibernate starts in the logs and maps User etc. classes. Remember to configure your Log4J or what ever logging u use to debug. I added some lines to log4j.properties to turn on hibernate logging (debug), but I see no output - just the usual Tapestry debug output that I've seen before. I'm really stumped... :-( Hibernate never gets called and yet everything appears to be in place. p. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
