CORRECT portlet+spring+hibernate configuration (Two options,
what's right?)
Hi again,
For a shake of completeness y will provide two of the working
configurations I've found to work. I would know what's the one
correct and why. Someone can throw a little bit light on this issue,
please?

I found this to work well. Spring gets initialized and everything works.
The only problem I've found is that hibernate session does not start
when needed.
I have to check why. Maybe a problem with this configuration?
-=[ First Option ]=-
-----------------------------------------
web.xml
-----------------------------------------
Same above, but filters:
<!-- Wicket filters -->
<filter>
<filter-name>CustomerListPortlet</filter-name>
<filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
<init-param>
<param-name>applicationFactoryClassName</param-name>
<param-value>org.apache.wicket.spring.SpringWebApplicationFactory</param-value>
</init-param>
<init-param>
<param-name>applicationBean</param-name>
<param-value>customerListPortletBean</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CustomerListPortlet</filter-name>
<url-pattern>/CustomerListPortlet/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>INCLUDE</dispatcher>
</filter-mapping>
<!-- END Wicket filters -->
So the application is a bean that gets initialized by Spring.
-----------------------------------------
portlet.xml
-----------------------------------------
Same but portlet gets:
<portlet>
<description>Customer viewer</description>
<portlet-name>crm-customer-list</portlet-name>
<display-name>Customer details viewer</display-name>
<portlet-class>org.apache.wicket.protocol.http.portlet.WicketPortlet</portlet-class>
<init-param>
<name>wicketFilterPath</name>
<value>/CustomerListPortlet</value>
</init-param>
<supports>

</supports>
<supported-locale>es</supported-locale>
<portlet-info>
<title>Customer viewer</title>
<short-title>Customer viewer</short-title>
<keywords>none</keywords>
</portlet-info>
</portlet>
Now it's a wicket portlet but I really don't know why it uses the
correct portlet class as is not defined anyplace...

I think this option is darker than the other one. But I think none of
both are right. So What's the correct way to do it?
Thank you!

Well it depends, if the hibernate filter should be activated at the
same url's as wicket.
I've never had a case where my wicket filter and osiw did not match.
You might have performance increases if they differ, for example if
you know that you willl never use hibernate on /myapp/ but always put
in /myapp/pages/dynamic/* for pages that use db lookup..

Will check. I didn't know about filter order... Will also check it.

No, It's different. Can I set it to just "/*"? Should I do it that way?

Re: CORRECT portlet+spring+hibernate configuration (Two options,

Posted by nino martinez wael <ni...@gmail.com>.
Hmm
I have several suggestions.
The order of the web filters are important. You could also try with
with the wicket spring managed apps, im not sure how that applies.
And are you sure that your filter ( /hibernate/*), get's hit? What's
your wicket filter url, the same or?

Re: CORRECT portlet+spring+hibernate configuration (Two options,

Posted by Gonzalo Aguilar Delgado <ga...@aguilardelgado.com>.
Ok. Maybe I don't understand...
Let me show the situation. I have Spring + portlet + hibernate config
with transactions working with the current configuration:
I have my DAO objects under package
com.level2crm.hibernate.enterprise.dao.contact
And model under com.level2crm.model
I configured one advice:
<tx:advice id="txAdvice" transaction-manager="txManager">
<!-- the transactional semantics... -->
<tx:attributes>
<!-- all methods starting with 'get' are read-only -->
<tx:method name="get*" propagation="REQUIRED" read-only="true" />
<!-- other methods use the default transaction settings (see below)
-->
<tx:method name="*" propagation="REQUIRED" /> <!--
propagation="SUPPORTS" -->
</tx:attributes>
</tx:advice>
And several pointcuts:
<aop:config>
<aop:pointcut id="allModelOperation" expression="execution(*
com.level2crm.model..*+.*(..))"/>
<aop:advisor advice-ref="txAdvice"
pointcut-ref="allModelOperation"/>
</aop:config>
<aop:config>

<aop:config>
<aop:pointcut id="TRG" expression="execution(*

<aop:advisor advice-ref="txAdvice" pointcut-ref="TRG"/>
</aop:config>
<!-- This one does not work -->
<aop:config>
<aop:pointcut id="portlets" expression="execution(*
com.level2crm.portals.crm.wicket.customerlist.pages..*+.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="portlets"/>
</aop:config>
I tried to configure the open session in view (web.xml):
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- Enable the filters for Hibernate -->
<filter>
<filter-name>opensessioninview</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>opensessioninview</filter-name>
<url-pattern>/hibernate/*</url-pattern>
</filter-mapping>
<!-- END hibernate filters -->
But I found that this does not work. Because:
public class ViewModePage extends org.apache.wicket.markup.html.WebPage
{
...
@SpringBean(name = "userDAOBean")
private UserDAO userDAO;
IModel loadableUserModel = new LoadableDetachableModel() {
@Override
protected Object load(){
User selectedUser = null;
String value =
((PortletRequestContext)RequestContext.get()).getPortletRequest().getParameter("crmportal:userId");
if(value!=null)
{
UuidUserType uuid = UuidUserType.fromString(value); //Works!!
userDAO.testSessoion(uuid);//Works!!
selectedUser = userDAO.find(uuid);//Works!!
if(!userDAO.isAttached(selectedUser)) //Works!! But is not
attached!!!
{
userDAO.save(selectedUser); //Attach it //Works!! It
saves/updates the object but it's still not attached
}
Set<ContactBasicDetail> setDetails =
selectedUser.getContactBasicDetails(); //Works!! It gets the set
setDetails.isEmpty(); // FAIL FAIL Cannot load lazy
return setDetails.toArray();
}
return null;
}
};
...
}
This load() function does not work! It makes the exception. But:
1.- It can get the User. Because the pointcut works inside the
DAO?
2.- It can save the object. Because the pointcut works inside
the DAO?
3.- It can get the Set. Because the pointcut works inside the
DAO?
The userDAO.testSessoion(uuid); function inside the DAO object works.
What I do is to get the Hibernate session, check that is ok. And check
also if the transaction was created and I can attach and use object.
Inside the userDAO.testSessoion function I do the same code that in the
load() function but this time everything works!
I'm sure that it works because it has a session and a open transaction
due to the pointcut defined as follows works above:
<aop:config>
<aop:pointcut id="allDAO" expression="execution(*
com.level2crm.hibernate.enterprise.dao..*+.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="allDAO"/>
</aop:config>
What is not working is the pointcut that should provide a
transaction/session to the page:
<!-- This one does not work -->
<aop:config>
<aop:pointcut id="portlets" expression="execution(*
com.level2crm.portals.crm.wicket.customerlist.pages..*+.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="portlets"/>
</aop:config>
And I think this has something to do with the hibernate+wicket
configuration. As the page is not created by the Spring bean interface
it cannot
make a proxy around it. So it will never get the session/transaction.
Opening a session with the view manually will make my pointcuts not
usable so I will loose the control over what classes
will be managed and over transactions. Do will I?

Yep, I do it but it does not work. Indeed it fails inside the load()
function. That makes me thing something is wrong configured...

Sure?
But I will loose control over how transactions are managed...

Re: CORRECT portlet+spring+hibernate configuration (Two options,
what's right?)
Posted by Gonzalo Aguilar Delgado <ga...@aguilardelgado.com>.
About the error I mentioned the exception it throws is:
Caused by: org.hibernate.LazyInitializationException: failed to lazily

May this have something to do with selected configuration?
Thank you again.
