hi all,

We are integrating a struts-spring application with hibernate.

i have a DTO which has some variables.And i have mentioned the same in

my .hbm.xml file.

Now I have a variable which is a sort of a temporary var. it does not

exists in the database table.

How should i map this in my .hbm.xml file so that i get the methods in the

generated POJO class.

Thanks in advance.

I have not tried it, but maybe setting insert="false" update="false" in your property definition would do the trick.
<property
name="propertyName"
column="column_name"
type="typename"
update="true|false"
insert="true|false"
formula="arbitrary SQL expression"
access="field|property|ClassName"
/>

good luck!

Sorry, this will not work. Hibernate would still try to use the property for selects.

Read chapter '15.2.2 The meta attribute' of the reference manual. IMHO the class-code or extends attributes are for you.
An other way would be to extend the generated POJO.

hi ,

I tried with this piece of code and was able to get the work done.


<property name="longDescription" type="string" insert="false"
update="false">
<meta attribute="field-description">The name of the Country</meta> </property>


Thank you.

Mmm ... Are you sure this works if you do session.get(POJO.class, id)?

IMHO this will result in Hibernate asking for a longDescription field as soon you try to load an instance of you POJO. I'd expect an SQLException.
