Embedded in JDO metadata not working in objectDB 2.x ?

Hi, I am using JDO access to the database with the persistence defined in package.jdo XML metadata files. In those metadata files I have few persistence-capable classes which had extents in ObjectDB 1 (with an OID for every instance) and all other classes were embedded (so without extent and own OID) in those few peristence-capable ones.

Failed to create a new file 'target\objectdb\log\archive' (error 112)

Hi, we are using ObjectDB 2.4.6_10 (embedded mode). The pre-registration of a data type (see below) fails because ODB can't create a new file in a non-existing folder hierarchy.

Do we have to create it beforehand? This issue is affecting our integration tests against ODB and is pretty major for us. Thanks ... Hi, we are using ObjectDB 2.4.6_10 (embedded mode).
