Hi guys,

I m using org.apache.commons.lang.RandomStringUtils to generate id for a table.


<id
name="id"
column="category_id"
type="java.lang.Long"
unsaved-value="null"
>
<generator class="assigned">
<!--
To add non XDoclet generator parameters, create a file named
hibernate-generator-params-Category.xml
containing the additional parameters and place it in your merge dir.
-->
</generator>
</id>



How should I write a class to put into the mapping document so that I don't don't to specifically called org.apache.commons.lang.RandomStringUtils everytime I insert a record.
TIA !!

best regards,
Mark

Write a class implementing the interface org.hibernate.id.IdentifierGenerator and specify that class in the id section of the mapping document.



It's explained here http://www.hibernate.org/hib_docs/v3/reference/en/html/mapping.html#mapping-declaration-id-generator

is it recommend to write your own identifier instead of using hibernate built-in id generator??
