Hi All,

Please help us regarding below issue

We are using hibernate3.jar and all mapping files and entity classes looks fine but still we are getting the below exception

org.hibernate.PropertyAccessException: IllegalArgumentException occurred while calling setter of com.entity.GroupParent.parent
at org.hibernate.property.BasicPropertyAccessor$BasicSetter.set(BasicPropertyAccessor.java:104)
at org.hibernate.tuple.entity.AbstractEntityTuplizer.setPropertyValues(AbstractEntityTuplizer.java:337)
at org.hibernate.tuple.entity.PojoEntityTuplizer.setPropertyValues(PojoEntityTuplizer.java:200)
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Please find the below mapping file and entity class

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

<hibernate-mapping>

<class name="GroupParent"
table="TROUBLE_GROUP"
schema="TEST" dynamic-insert="true" dynamic-update="true">

<id
name="id"
type="java.lang.Long"
column="ID">
<generator class="sequence">
<param name="sequence">TROUBLE_GROUP_SEQ</param>
</generator>
</id>

<property

column="VERSION"
length="16"/>

<property
name="ticketNumber"
type="java.lang.String"
column="TICKET_NUMBER"
not-null="true"
length="25"/>
<----------------- SO ON ------ WE HAVE OTHER MAPPINGS>
<many-to-one name="parent"
class="GroupParent"
column="PARENT_ID" not-null="false" lazy="false"/>
</class>
</hibernate-mapping>
----------------------------------------------------------------------------------------------------
ENTITY Class:
GroupParent.java
------------------
public class GroupParent implements Group {

private Group parent;
void setParentId(Long parentId) {
this.parentId = parentId;
}

}

==================================

the answer for the above issue is we have changed the field name from name="parent" to name = "par" . We didnt know why hibernate is behaving like this???? may be parent field name willnot be allowed by hibernate??
