I want to persist the entity generated time using hiebrnate generated properties. In the mapping file I have the following entry.

<property name="generatedTime" update="false" insert="false" type="java.util.Calendar" generated="insert" access="field">
<column name="GENERATED_TIME" not-null="false">
<comment>Report Generated time</comment>
</column>
</property>

My POJO contains the getter and setter for the 'generatedTime' property.

But when I persist the entity , GENERATED_TIME is always set to null. Is there any way to set the current date as the GENERATED_TIME using the mapping file.

Is the value in fact generated in the database (please check the table data itself outside hibernate)? If so, is the SELECT issued just after the INSERT? To check this, enable DEBUG logging for org.hibernate.SQL or set hibernate.show_sql to true in your config properties.

No value is not generated in the database.

But I have used the following approach to get the things working.

<property name="generatedTime" type="java.util.Calendar">
<column name="GENERATED_TIME" not-null="false" default="sysdate">
<comment>Report Generated time</comment>
</column>
</property>

Now this is working fine. But I'm not sure whether this is the correct approach. Could somebody can point out the problem with earlier appproach?

You need to understand what "generated" means. It means that the value is generated by the database and Hibernate has to re-select the row to learn the value. If you don't setup your table to have a trigger or default value, then generated isn't going to result in anything.

HTH,
