OJB XDoclet module Missing element class ref on @ojb collection
not handled
[I tried to submit this as a bug, but a Scarab bug[1] seems to be
preventing me :-( ]
Using the xdoclet stuff packaged in db-ojb-1.0.rc5-contrib:
If the element-class-ref attribute is missing from the @ojb.collection
tag, an internal error occurs which is not handled and reported clearly.
You should get an error message like 'Could not determine collection
element type; missing element-class-ref attribute. Instead you get a
huge stack trace which doesn't communicate the problem:

[1] When I hit Submit Issue, scarab responds with "Alert! More
information was required to submit your request. Please scroll down to
see error messages." The only error message is on the Description field,
which says "ERROR! Missing resource (actersUAttachmentOrComment)".
I have no idea what that means or how to fix it... It might be an idea
to follow up with the Scarab guys if you care about people submitting
bug reports, etc! ;-)

Thanks! Good to see that something I wrote because I was too lazy to
manually keep repository descriptor and source consistent ;-) is useful
to other people as well.

Doh! I don't know how I missed that! :-)
Thanks for the pointer,

You can use the column attribute of the ojb.field tag to achieve this. If
no value is specified for the column attribute, the XDoclet module will
use the java name (after some adjustments, e.g. for nested fields) or the
value of the name attribute (for anonymous fields).
As a general rule, almost all attributes in the repository descriptor have
a corresponding attribute of the same name in the tag corresponding to
the XML tag in the descriptor. E.g. to specify the column that a field
maps to (XML attribute field-descriptor.column) you would use the
attribute column of the tag ojb.field. Likewise for class-descriptor.table
the attribute table of ojb.class.
There are some exceptions where this wouldn't make sense either because
the info is already present in the Java source (e.g. the name attribute of
the descriptor) or is handled differently (usually easier e.g. nested
fields).

I realise it has to match up on the Java/OJB side, but the table column
name can be anything, as in:
<field-descriptor
name="someProperty"
column="THE_COLUMN"
jdbc-type="INTEGER"
nullable="true"
access="anonymous"
/>
Basically, I'd like the 'name' property from ojb.field to control the
value of 'column'. Does that make sense?

Nope, it is required to be the same as the real name of the java field,
otherwise OJB wouldn't find the field. So in short, you cannot specify a
different name (as this would refer to a different field). You can however
add anonymous fields (put a field tag in the class javadoc comment with a
name attribute).

Just to let you know: yes, that fixes the problem. The CVS version
reports the error cleanly (well, still with a big stack trace, but
that's not your fault ;-). Thanks for the pointer!
Something it doesn't seem to fix (which is not so much a bug as an 'I
thought it would work this way' thing) is that 'name' attributes on
ojb.field tags are ignored. I know you can infer a name based on the
name of the Java property being mapped, but if I explicitly specify a
different name I'd like it to be used. Is there a way to get that to happen?

Please use the CVS version of the XDoclet module which is way improved
over the rc5 version (you don't have to use OJB from CVS, only the XDoclet
module). You can get it from the ViewCVS access from the OJB website
(http://cvs.apache.org/viewcvs/db-ojb/). Download the three jars
xdoclet-1.2.jar, xdoclet-ojb-module-1.2.jar, and xjavadoc-1.0.2.jar from
the lib folder, and also the documentation (xdoclet.xml) from the xdocs
folder (html is build via 'ant htmldoc').
If the problem persists, please post the stacktrace that the CVS
module version generates.
As for the stacktrace, I can't do much about it, XDoclet 1 is not known
for its user-friendly error messages. A conversion to XDoclet 2 is
planned for OJB 1.1 though.
