[Hibernate] Unit Testing With ThreadLocal Sessions
Greetings. I am interested in hearing how people unit test method that call session.save(), update(), and delete() when the session is provided via the ThreadLocal pattern. For me, the primary question is whether or not the method containing the session method calls actually closes the database connection (session.close()) or is it called after returning from the tested method. From a pure unit testing stand-point, it would seem that it would be desired to be called inside the tested method. For a project I am working on, we devised a solution (aka hack) to solve this. A new Session interface implementation was created that wraps an internal Session object as normally provided. Yet, we added 2 methods: suspendClose() and unsuspendClose(). When closes are suspend, the connection is NOT closed despite being called. Specifically, it does not call session.close() on the internal Session object. When a Session is retrieved, the closes are automatically suspended. The servlet filter unsuspends the close and closes the session if necessary at the end of the request. Is this a hack? Yes. Does it work? Yes. Do we get the benefits of a ThreadLocal session? Yes. Can it be confusing to newbies who expect close to actual close the session? Yes, but it only has this behavior during deployment. Any thoughts and comments are welcome.

Re: [Hibernate] Unit Testing With ThreadLocal Sessions
My only concern with this is that the business logic component is now coupled with the web tier. For this project (which is basically a framework), we want to be able to use the components internal and external to the servlet container. However, I do appreciate the feedback! It helps confirm my thinking regarding potential solutions. Cheers, matthew On Wednesday, August 6, 2003, at 07:29 AM, Joseph Fifield wrote: I don't close the session at all in any of my business logic methods. In deployment, a servlet filter _always_ closes the session at the end of the request. For unit testing, I have a base test case class that does the same thing in the tearDown() method. That way, each test case can execute in the same manner as the app running in deployment (i.e. each test case is like a separate "request"). The result is each test case executes using the same session, and they don't need to worry about closing it at the end. Hope this helps...

Re: [Hibernate] Spring Framework Integration along with Open Session In View
Sandeep: I just had this conversation with the Spring guys last week. You may want to check their mailing list. Here's the abridged version: You can do it. It is a nasty hack of the system (and beauty of Spring). The mailing list includes the necessary filter on how to do it. However, it is not really recommended due to how Spring uses transactions.

Now, I am trying to retro-integrate the Spring Framework into the mix. Juergen's docu was excellent, but I was wondering (before I end up doing it all myself the hard way) if anybody had used Spring + Open Session In View together, and had, um, er any sharable code handy? Thanks in advance Sandeep
Re: [Hibernate] A Proposal: Opensymphony Conductor
Jason: I am all for this. I have some new hibernate infrastructure stuff coming today and some patches to OSUser/PropertySets that solves the current performance issues.

If you're interested, I'd love to get feedback and I'm soliciting offers of people's time and code to help set this up. Especially the JLCP guys, who I know have set up some infrastructure for WW2 and Hibernate, so that would be very helpful. I think this would go a long way to addressing people's concerns about ease of use (how much easier can it get without a GUI to hold your hand and eventually strangle you :-)?)

Jason - sounds like an interesting idea, but could we focus on getting WW2 / XW finished and released first? :) I disagree. To me, this seems like the next logical progression of WW2/XW and the other tools. It could serve as a way to show the power of WW2 and entice more developers to use it.

Re: [Hibernate] CGLIB2
Please note. I am not asking/suggesting to change to version 2 because of its faster reflection code (although every little bit helps!). I am asking because we want to use some of the other new features. Cheers, matthew On Oct 27, 2003, at 5:42 PM, Josh Rehman wrote: Hmm.

[Hibernate] Subclassing And "net.sf.hibernate.MappingException: No persister for" Exception
Please help!!! (I hate sending e-mails out like this, but am crunched
for time.)
First, I am using Hibernate 2.0.3 and Spring.
I have a interface called PaymentType which has 2 implementing classes-
CreditCardPaymentType and EmailPaymentType. I am able to persist new
PaymentTypes without issues; however, when associating a PaymentType to
another object (Registration), I receive the following exception:
No persister for:
com.demandsolutions.merovingian.payment.entity.PaymentType; nested
exception is: net.sf.hibernate.MappingException: No persister for:
com.demandsolutions.merovingian.payment.entity.PaymentType
Registration.java
public class Registration extends BaseEntityObject {
private PaymentType paymentType;
// other variables and methods..
// Hibernate Mappings declared in supplementary file!
public PaymentType getPaymentType() {
return this.paymentType;
}
public void setPaymentType(PaymentType paymentType) {
this.paymentType = paymentType;
}
}
Registration.hbm.xml
// other declarations
Any and all help is appreciated! Thanks in advance!
Cheers,
matthew

Re: [Hibernate] Subclassing And "net.sf.hibernate.MappingException: No persister for" Exception
Any guess on where I can start looking for the problem? One other thing I did not detail is that CreditCardPaymentType is an abstract class with a few implementations. This is holding up a site from being deployed and driving me absolutely crazy! Thanks in advance!
