Class is not mapped
Hello,
I am new to using Cayenne so I decided to first start by going through the
tutorial. All went fine until I tried to build my project. I get an error
that says:
Exception in thread "main" java.lang.IllegalArgumentException: Class is not
mapped with Cayenne: org.example.cayenne.persistent.Artist at
org.apache.cayenne.access.DataContext.newObject(DataContext.java:689)at
org.example.cayenne.persistent.Main.main(Main.java:11)
I guess I'm looking for a reason why my classes are not mapped with cayenne.
Thank you in advance

The AUTO_PK_SUPPORT table is used (and created) by Cayenne to generate
primary keys. When you create your DB schema in Cayenne Modeler it
can automatically create that table for you (this is the "Create
Primary Key Support" checkbox option). The easiest thing to do,
probably, is use Cayenne Modeler to generate that table for you (only
select the "Create Primary Key Support" option so you don't overwrite
other tables/etc).

commit exception always has its cause, so you need to investigate (and post
here if needed) bottom stack trace of the exception

Thanks for you reply. I think I have fixed my initial problem, there was a
problem with the cayenne.xml file. But now I am having trouble with my
context.commitChanges() line. I am getting this error:
Exception in thread "main" org.apache.cayenne.CayenneRuntimeException:
[v.3.0RC1 Jan 05 2010 14:44:59] Commit Exception
at
org.apache.cayenne.access.DataContext.flushToParent(DataContext.java:1134)
at
org.apache.cayenne.access.DataContext.commitChanges(DataContext.java:1045)
at org.example.cayenne.persistent.Main.main(Main.java:30)
which doesnt make much sense to me except that I understand that
commitChanges actually sends the data to the database to be saved.
Otherwise I'm lost.

Hi,
What version of Cayenne are you trying? To check if everything's mapped
well, open cayenne.xml with Cayenne Modeler, find ObjEntity (green icon)
Artist and make sure that org.example.cayenne.persistent.Artist is specified
as class name. But, if you hadn't changed anything in tutorial project, I'm
not sure why it cold have broken
