Hello,
yesterday I have got this problem:
I have my java app that use Hibernate (3.0) for make search on DB (MySQl 5.0).

If I sent a search method (with hibernate method "session.createCriteria"), sometimes it worked good, and sometime it gives me this error:
"

I don't understand why I have this error "Could not read mappings from resource: basket.hbm.xml" if sometimes it works!.

Can you please helpme to understand the problem (or cause)?? It's very URGENT!!

Thanks,

Looks like the SAX parser is having trouble reading something over the network which explains why it works sometimes and not others.

If you're using hibernate 3 the DTD is wrong in Basket.hbm.xml:


Should be



You might need a local DTD catalog to prevent the xml parser going to the internet.

Hello,

I have tried to change the version from 2.0 to 3.0, but I have this error:

org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: it.eminds.data.Basket.servizi, no session or session was closed

I think, this because, after search, I close the session, and then I use the object "Basket" for read that!
But why with 2.0 it works?!

This is the log:

The lazy attribute for <bag> was defaulted to "false" in the v2 DTD so the SAX parser is setting it to false for you. In the v3 DTD lazy is #implied i.e. optional. The implementation defaults collections to lazy="true". This is why you see a difference in behaviour.

Just add lazy="false" to your bag.
