Hi

I am getting an exception in my Hibernate application. The database I am using is Mysql 5.1

Below is the partial stack trace of my exception.

he following exception was logged org.hibernate.PropertyAccessException: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of com.javacertificate.data.table.Exam.setField1
at org.hibernate.tuple.PojoEntityTuplizer.setPropertyValuesWithOptimizer(PojoEntityTuplizer.java:215)
at org.hibernate.tuple.PojoEntityTuplizer.setPropertyValues(PojoEntityTuplizer.java:185)
at org.hibernate.persister.entity.AbstractEntityPersister.setPropertyValues(AbstractEntityPersister.java:3232)
at org.hibernate.engine.TwoPhaseLoad.initializeEntity(TwoPhaseLoad.java:129)

..............................

This is my database details for this field.

+---------------+--------------+------+
| Field | Type | Null |
+---------------+--------------+------+
| FIELD1 | bigint(20) | YES |
+---------------+--------------+------+

my mapping is

<property name="field1" type="long">
<column name="FIELD1" />
</property>

and following is my java class.

private long field1;

public long getField1() {
return field1;
}

public void setField1(long field1) {
this.field1 = field1;
}


How can I resolve this problem. Please help me

Maybe the content of field1 in the database is null and you try to set null to a long. change the property type in your class to Long

Hi,

It is always advisable to use Object wrappers instead of primitive types in Hibernate classes.

More better way of doing it is to not write the hbm file urself but feeding the Db to an Hibernate-Supported IDE such as eclipse 3.0 and then get it to generate the hbm file for you.

Any comments??

Thanks for your help.

When I changed 'long' to 'java.lang.Long' it worked.
