I am using a config file and no EJB etc
Castor works for me but not Hibernate I'd like to use hibernate cause of the rich feature set.

Exception

You are probably importing the Product class/mapping twice.

I'm definitely not importing the class twice
I've seen similar posts for the problem but no solution

Can you make a main method and a corresponding hbm.xml and config.xml file and reproduce it ? If yes - then show us that and i'll look at it agin.

I used your posting mapping and could not reproduce it!?

Found the issue

I had errors in my mapping file.
String instead f string
generator class was blank

The exception being thrown was the MappedException: duplicate record

The only way I found out was by debuggin right into the hibernate src.
BindColumns or somemethod like that was throwing exceptions


Thx for the feedback anyways




[b]Thing to remember is that[/b]
[i]If there are errors in the mapping file
net.sf.hibernate.MappingException: duplicate import: Product
exception is being thrown[/i]

hmm...strange...

That sounds like a "not-so-user-friendly error message"....

I must have been running the wrong mapping when testing coz' i did not get that error.....but I'll encourage you to post a hbm.xml that throws this bad error and then add it to the JIRA

I've already posted the contents of the configuration file
and the mapping file in my first post.

if u look at the mapping file you'll see the errors in it

type= "String" instead of type="String"

and a empty generator class in the id node

<generator class>
</generator class>

I'm tried this on the release and beta 6 codebases and got the same effect.

I'll add to JIRA I'm new to this so will figure out how.

yes - but it's just much easier for us if you attach them as files to a JIRA ;)



Don't worry it's easy ;)
