Persistance

[André Höing]

Hi,

I marked an self-written object with the @Persist annotation but it
seems that UNICORE does not persist it completely. Another Object where
I did the same works fine.

In this class, I declare a private HashMap<String, String> and private
HashMap<String, List<TrustDelegation>> but between 2 independent  calls
on the same service instance the content of that HashMaps disappears. I
think that all used Objects are Serializable.

Must I use activate and passivate manually in this case?

Thanks for the help,
André

hi,

would it be possible to condense this into a testcase?
Maybe there is a problem with serialising the objects involved.

Best regards,
Bernd.

Hi Bernd,

I tried to create a testcase, but I do not know how to create a  
correct for WSRF Persistence testing. So I just tested the  
serializability and it seems to work.

I attached the testcase and the Object that is empty after Unicore  
reloaded it.

Thanks,
André

hi,

one possibility might be that you need to set the "dirty" flag on the WSRFInstance, by calling "setDirty()"
before the ws resource is persisted. So when you change the data to be persisted you need to make sure setDirty() is called.

Best regards,
Bernd.
