Hi ,
I am not able to read property attributes like default value etc from hbm file, could any of you help me in doing that. I tried using ClassMetaData but it was of no help as I was only able to read specific attributes of any property and not all the attributes of the property.
I am using Hibernate 3 and Oracle db 10.2.0.3

Hi,

could you be more specific? What property do you want to extract from which file. Generally properties are placed in hibernate.cfg.xml or hibernate.properties (peristence.xml in case you are using JPA) and given that you have an instance of Configuration you can just call Configuration.getProperties().

If you want to get access to the actual configuration data of a single mapped classed you will have to go via the meta data. The mapping data is not available as standalone values.

Actually I want to read property attributes from hibernate mapping file
like property column have values precision , unique , default, scale etc . I want to read these attributes from mapping file of particular table and use it in my program for making some validations.

sample mapping file :

<hibernate-mapping>
<class name="com.test.XYZ" table="TEST" schema="XYZ">
<id name="opid" type="big_decimal">
<column name="OPID" precision="22" scale="0" />
<generator class="assigned" />
</id>
<property name="name" type="string">
<column name="NAME" length="960" not-null="true" unique="true" />
</property>
<property name="description" type="string">
<column name="DESCRIPTION" length="4000" />
</property>
<property name="createcopy" type="big_decimal">
<column name="CREATECOPY" precision="22" scale="0" not-null="true" />
</property>
</class>
</hibernate-mapping>

I want to read unique attribute from property name
If you want some more details please do let me know

Hi,

I don't think you can read this values as properties. If it is not part of ClassMetaData you won't be able to get to it.
If you want to build validation into your domain model maybe Hibernate Validator is for you. Have you had a look at this project?
