Hello,

i'm using Hibernate Tools, 3.2 beta 8 and after creating the Console configuration where i've specified additional mapping files and path to classes with DB jar. Then it raises "Error while fetching children" and in the details it says that cant fing the mapping class. I'm confused about the reason why, i think that it is bug, because i've specified the exact class-path.

Then i went step-by-step by attaching each mapping and finally found out the problem!

Actually it breaks on the custom type for the column

<property
name="confirmationType"
access="field"
type="com.xxx.model.custom.ConfirmationEnumerationType"
column="confirmation_type"
not-null="true"
update="false"
>

So when i've removed that property from the mapping the console configuration started nicely without errors.

Any suggestions? It must be a real bug!

The other further thing is when i click on the Session Factory then it writes:
session factory error: could not instantiate cache implementation
Error

so how is to resolve that?

well after adding some more props it started working well:
<property name="hibernate.jdbc.batch_size">0</property>
<property name="hibernate.cache.use_second_level_cache">false</property>

anyway, why this additional information is not specified in the installation manual???

so the question remains: what to do with custom types in the mappings???

And i have one more problem for criteria editor code completion: it writes
Error while performing code completion
Reason:
Console_name doesn't exist

While in HQL editor table-completion is working nicely for Console_name.
Is this also the bug?

There is *nothing* special about hibernate tools in the respect of configuring Hibernate. Just do the same as if you needed to run Hibernate.

The pojo classes (and *dependendent* classes) needs to be on the classpath and your custom type is apparently not on the classpath and the same with your cacheprovider.

Btw. I'm quite sure the stacktrace mentioned the exact reason for the failing startup.
