These classes no longer included in OJB jar. But the source code of both 
classes is included in OJB project source code. You can still use these 
classes or bind OJB to JNDI by your own or use OJB.getInstance() directly.
We removed the JBoss mbean to get rid of JBoss dependencies in OJB jar file.

Between ojb 1.0.4 and ojb.1.0.rc4 are some differences, so please 
carefully read the release-notes to get an impression of changes.

In 1.0.4 we harmonize the Identity handling and I forgot to note this in 
release-notes. Here you can find a detailed description
http://www.mail-archive.com/[email protected]/msg15405.html

It's strongly recommended to use the IdentityFactory to create Identity 
objects (e.g. for "lookup by PK") instead of creating Identity objects 
by your own.

In OJB 1.0.4 the jdbc-connection-descriptor attribute "eager-release" is 
supported the last time. Since JBoss 3.2 the statement issue is fixed 
and this attribute is no longer needed.
