unforunately i have an "please help, urgent" mail here:
i am developing an ant task that builds a schema as well as a
mapping file from JDBC meta data, and from what only
looking at the result: the genereated files seems to be OK (still
have some specific type conversions left).
of course i run a junit-test on this which plagiarises the "Using JDO"
from the documentation (and is attached).
also of course, i've stranded on an exception (see last this letter) from
the test. this seems to be happening as castor is registerring a new bean
within my new context.
any guru solves this in a sec?
awkwardly, mats
