The Object is simple.
It is working fine for 50, 100 objects... But When I have 600 objects I got the out of memory error.
I have tested in 3 different computers with 256Mb (ram),
starting java with -Xmx256m
query = new QueryByCriteria(NomePrestador.class, crit);
iter = broker.getIteratorByQuery(query);
<class-descriptor
class="com.maximas.sinret.data.NomePrestador"
table="NomePrestador"
>
<field-descriptor
name="id"
column="id"
jdbc-type="INTEGER"
primarykey="true"
autoincrement="true"
/>
<field-descriptor
name="nome"
column="nome"
jdbc-type="VARCHAR"
/>
<field-descriptor
name="id_empresa"
column="id_empresa"
jdbc-type="INTEGER"
/>
</class-descriptor>

Without knowing more about your system this is hard to answer.
If there are no problems with your repository.xml it could be that you
simply should start your server with more heap memory.
But if there are problems in the mapping, this won't help.
So you should start by checking your repository.
what can be problematic? Loading 1 root object with 600 dependend
objects shoul not be a problem (we are loading 10000 objects and more in
our testcases).
But if the registers objects have references to objects, and those
objects to yet another layer of objects, you are in trouble as OJB must
load a very large Object graph in one go.
The solution can be to set proxy="true" for those reference- and
collection-descriptors. In that way you avoid loading in one go and
defer the loading of dependend objects.
