Hi all,

I'm getting a PropertyAccess exception and the following message: "exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer = false for more info).

I have read that I can't set this value in hibernate.cfg.xml - so I tried creating a hibernate.properties file in /WEB-INF/classes and using that instead - however that results in an error saying my classes are no longer mapped.

In my hibernate.cfg.xml file there are the usual references to all my mapped classes - eg.

<mapping resource="blah/blah/blah.hbm.xml"/>

I assume that because I'm not using the XML file anymore, it's missing this information - how do I specify these values in hibernate.properties?

That exception is not talking about the cglib property, it's talking about a property on one of your Objects.

Show the complete stack trace if you want more help.

And yes, you need the <mapping> elements to identify your objects to hibernate. Stick with the hibernate.cfg.xml.

Where do I get this stack trace? I was under the impression that the message to set hibernate.cglib.use_reflection_optimizer = false would give me this stack trace.

I've tried putting try/catch and printStackTrace() inside the setter of my object, but that doesn't seem to do anything.

Your initial post says
I'm getting a PropertyAccess exception and the following message: "exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer = false for more info).

Is there no stack trace with the PropertyAccess exception ?

There is a stack trace, but it seems to be coming from the CGLIB generated class, not my actual class - meaning that it doesn't do me any good for trying to figure out what's causing the PropertyAccessException.

I assumed this was why it told me to set gibernate.cglib.use_reflection_optimizer = false.

http://www.hibernate.org/ForumMailingli ... AskForHelp

There is a very good reason that the forum policy tells you to post your mapping files, your code, and any stack trace. That's what it takes to solve problems. Vague descriptions are not enough.

You can set this property from your hibernate.cfg.xml as:

<property name="hibernate.cglib.use_reflection_optimizer">true</property>

This will you a more descriptive error message. I've run into this issue mostly from mapping nullable colums to primitive types :)

The stack trace unfortunately is just shown in my command window (I'm using Ant with Junit and don't know how to redirect that output) but the source is WQSample.setAnalyteID.

It looks like there's a ClassCastException happening that is causing this. However when I check the contents of the DB that field only contains integer values.

Hibernate should understand how to convert a MySQL bigint(20) into a java.lang.Long, correct?

Setting this value doesn't change the output I'm getting.

The column in question doesn't contain any null values.

Perfect, thanks -

I've tried changing all the java.lang.Longs to long, that didn't change anything, then I tried changing them all to primitive ints - still getting the same error.

Doesn't really make any sense that I'm still showing a ClassCastException when I'm only using primitives...

Hi

If you used Interceptor interface in your application, you need return null in method instantiate of class what implement Interface Interceptor. I make this in my tests.
