Persistence

[csouillard]

Hi all,

let me introduce Guillaume Porcher which is one of our new developer in Bpm Bull team !
Guillaume will work around persistence both in PVM and BPEL/XPDL extensions.
For the moment he is working on inheritence-mix project to introduce JPA.
Fell free to ask him questions and for sure answer his questions !

Hi all,

I have a question about the mapping of the class org.pvm.jpdl.ProcessState:

in the package org.pvm.jpdl, we have:
class ProcessState implements Executable

in the mapping file ProcessState.hbm.xml, we have:
<subclass name="org.pvm.jpdl.ProcessState" extends="org.pvm.jpdl.JpdlExecutable"
discriminator-value="P">

Why do we have two different inheritance hierarchies ?

Thanks for your help
Guillaume

sorry for the delayed reply.

the mapping is obsolete. there is only 1 inheritence hierarchy of executables.

the difficulty is that it should be mapped in with mixed mapping strategy. all the pvm related properties should be in a single, central pvm table. all the classes related to 1 process language should be mapped flat into one 'extension' table.
