Open session in view (JPA, struts2, Spring 3, Hibernate4)
Because of a "limitation" (which is rather a bug) of Hibernate 4, I need
to switch to an open-session-in-view pattern in struts2
I was hoping that setting the right spring configuration in my web.xml
would do the trick (see below)
The session still dies before the view layer (ognl) has any chance to
lazy fetch from the database.
Is there anything struts-specific to make OSIV work?
I use Spring 3 and the EntityManager is from my JPA provider (hibernate).

How do you want Spring to find the Action?
autowire by name?
autowire by type?
IF you want Spring to create the Action then...
However, sometimes you might want the bean to be completely managed by
Spring.
(This is useful, for example, if you wish to apply more complex AOP or
Spring-enabled technologies, such as Acegi, to your beans.)
To do this, all you
have to do is configure the bean in your Spring applicationContext.xml
and then
change the class attribute from your Action in the
struts.xml to use the bean name defined in Spring instead of the class
name.
Your struts.xml file would then have the Action class attributes
changed..as defined here
struts.xml
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<include file="struts-default.xml"/>
<package name="default" extends="struts-default">
<action name="foo" class="com.acme.Foo">
<result>foo.ftl</result>
</action>
</package>
<package name="secure" namespace="/secure" extends="default">
<action name="bar" class="bar">
<result>bar.ftl</result>
</action>
</package>
</struts>

Why not to extend OSIV to /* ?

HTTP Session captures dynamic Session variables from Session initialisation to Session invalidation or timeout
a Database Transaction captures database information from Start to (commit or rollback)
Is there a reason why you would want your Session to be disconnected from the Database Transaction?

I guess the problem might be that the transaction boundary starts and ends within the controller class I wrote to manage entities. The action itself doesn't participate in the transaction. If my understanding is correct then the OSIV pattern needs an active transaction. Should I let spring manage the action in order to propagate the transaction to it?

Did you try to extend the url mapping to the whole root?
