<br>
I'm trying to implement bitemporal tables with the two layer
specification, separating Valid- <br>
Times and Transaction-Times each ones in their own classes. <br>
I've created a Bitemporal Stereotype, and i assign it to the
association between the two <br>
classes. <br>

Which version of andromda are you using? <br>
<br>
<blockquote type="cite"><br>
While modifying the HibernateEntity.vsl template I'm getting an error
that is turning me <br>
crazy... <br>
I've done a velocimacro with the following signature #macro (
isInHierarchie $aClass <br>
$aStereotype $found) <br>
<br>
This recursive method finds if one of the classes in the hierarchie of
the class passed as first <br>
parameter has an asociation labeled with the stereotype passedas the
second parameter. <br>
The third parameter is an outgoing boolean, also used as stop-condition
in the recursion. <br>

This applies only to version 3.0 of andromda: <br>
You should do this stuff in the Metafacade. Unfortantly there isn't
already a Metafacade to do this so I will explain how to create one. <br>
<br>
So first you have to add a new class with your needed function to the
Metafacede Model of the hibernate cartridge. <br>
You can create in the class new methods like isInHierarchie with your
needed parameter. <br>
You find the metafacade model in
<andromda-src-dir>/cartridges/andrmda-hibernate/src/uml/HibernateMetafacadeModel.xml.zip
<br>
<br>
You should call the new class HibernateEntityFacade. The class must
extend or in uml is generalize by EntityFacade. The EntityFacade you
will find in the
<andromda-src-dir>/\cartridges\andromda-meta\src\uml\MetaMetafacadeModel.xml.zip
<br>
<br>
You have to link or import this file in Magic Draw. <br>
<br>
Then you have to regenerate the metafacade: <br>
<br>
cd <andromda-src-dir>/cartridges/andromda-hibernate/ <br>
maven clean <br>
maven andromda:run <br>
<br>
Then you have to tell andromda when wo use this new class. So add the
following line to your
cartridges\andromda-hibernate\src\META-INF\andromda-metafacades.xml <br>
<br>
<metafacade <br>
metaobjectClass="org.omg.uml.foundation.core.UmlClass$Impl" <br>
metafacadeClass="org.andromda.cartridges.hibernate.metafacades.HibernateEntityFacadeLogicImpl"
<br>
contextRoot="true"> <br>
<stereotype>Entity</stereotype> <br>
</metafacade <br>
<br>
<br>
Now you have to add your new function to the LogicImpls. <br>
So goto
<andromda-src-dir>/cartridges/andromda-hibernate/src/java/org/andromda/cartridges/hibernate/metafacades
<br>
<br>
There will be a file called HibernateEntityFacade.java with your new
functions. Implement your function here. You have now all the power
that java has and java is much more powerful then velocity. <br>
<br>
Recompile the hibernate cartridge: <br>
cd <andromda-src-dir>/cartridges/andromda-hibernate/ <br>
maven jar:install <br>
<br>
and then try to rebuild your application. <br>
