exception setting property value with CGLIB

Hi,

I'm having problems when HIbernate tries to load a set.

The property Hibernate can't load is a String Object.

I get this error:
net.sf.hibernate.PropertyAccessException: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of fenaseg.rns.bo.ItemSinistroVeiculo.setStFraude

set hibernate.cglib.use_reflection_optimizer=false for more info

I think you will not get more info without optimizer, it says
setter of fenaseg.rns.bo.ItemSinistroVeiculo.setStFraude is mapped to a wrong type, just fix it.

The property is mapped as String

Code:

    <property
        name="stFraude"
        type="java.lang.String"
        column="ST_FRAUDE"
        length="3"
        not-null="true"
    >
        <meta attribute="field-description">
           @hibernate.property
            column="ST_FRAUDE"
            length="3"
        </meta>    
    </property>  

and is a VARCHAR2(2) in Oracle

Code:

Name                           Type         Nullable 
ST_FRAUDE                  VARCHAR2(2)  Y    

And I already added use_reflection_optimizer=false

Code:

<property name="cglib.use_reflection_optimizer">false</property>

This error onlu occours when running the web appl. The test cases all turn out fine

But it is very strange if you are sure, you have single mapping file in classpath, code in "<generated>" is something like this:

Quote:

void setPropertyValues( Object bean, Object [] properties ){

int index = 0;
ItemSinistroVeiculo itemSinistroVeiculo = (ItemSinistroVeiculo)bean;
try{

itemSinistroVeiculo.setStFraude((String)properties[0]);
index ++;

}catch(Exception e){
throw new BulkBeanException( e, index );
}

}

Is there anyone I can debug this piece of code? That's probably where the problem is since I have a ClassCastException. What I'd like to know is what is the type Hibernate is trying to cast my property to since every configuration file have the same type as the database.

You can try to attach remote debugger from IDE or use old good "System.out.println()" (It will be better to debug without optimizer, set cglib.use_reflection_optimizer=false as *System* property in server startup script or put "Hibernate.properties" file to classpath ).

I just found out what was wrong.

Our database data was imported from a mainframe and some of them have characters that can't be read as any type at all .

Thanks for your help.
