[Resin-interest] Hibernate lazy loading with Quercus
Title: Vincent LAUGIER
Hello,
we try to do the following on our php/EJB3 application :
find a given client from its lastname using a stateless bean ()
load his orders using the getter
[code]
$clients = $client_eao-findBySample($sample_client,false,false);
var_dump($clients[0]-getOrders());
[/code]
We get the usual LazyInitializationException :
[10:41:03.300] {http--8080-6$31582617}
org.hibernate.LazyInitializationException: failed to lazily initialize
a collection of role: com.opticneo.entity.client.Client.orders, no
session or session was closed
If we were using Hessian, before returning the list of clients we would
have made a copy of the list (using beanlib) before it is serialized
(in ordre to avoid LazyInitializationException)
With Quercus, we do not have to do this. Good ! But we face the
LazyInitializationException again when trying to access the complex
attributes.
What is the best way to handle this ? (maybe by taking control over the
transaction from the php)
Thanks for your help.
Regards

[Resin-interest] Resin 3.1.9 behind apache's ProxyPass problem
Hi , I am running resin 3.1.9 in my db server , with host name 'db' and private IP address (192.168.x.x). In the frontend , apache httpd redirect '/servlet' pattern to the backend db with the two lines : ProxyPass /servlet http://db:8080/servlet ProxyPassReverse /servlet http://db:8080/servlet In my servlet , I want to output a valid URL , linking to the webapp's some resources/apps But how do I get the correct [frontend] server name and port , instead of 'db' and '8080' ? In the resin.conf , I tried a lot of configuration , but all got : req.getServerName() = db , and req.getServerPort() = 8080 I need a correct URL , such as 'http://www.foobar.com/servlet/ooxx' , not http://db:8080/servlet/ooxx I tried some configurations , but all in vain : host id= host-name=www.foobar.com root-directory=/home/foobar/www host-aliasdb/host-alias web-app id=/ root-directory=./ /host and : host id=db host-name=www.foobar.com root-directory=/home/foobar/www web-app id=/ root-directory=./ /host and : host id= host-name=www.foobar.com root-directory=/home/foobar/www web-app id=/ root-directory=./ /host and : host id= host-name=db root-directory=/home/foobar/www web-app id=/ root-directory=./ /host and : host id=db root-directory=/home/foobar/www web-app id=/ root-directory=./ /host I am running out of ideas ... Can somebody help me ? Thanks in advanced ! ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest

Seems that the objects no longer have the association with valid session, so
either the Session or PersistenceManager should be kept around to fill the
objects in upon use. Forcing eager load could also be used I think.

I assume the easiest route here is to use a Filter to achieve
session/transaction per request.
