If you build the ojb-lockserver.war file as described in the 
documentation (ant lockservlet-war), all needed libraries are included 
in the .war file (hope so). You only need to deploy the .war file.

AFAIK the ojb-xxx.jar + all commons-xxx jar (from OJB lib directory) are 
included (think some commons-jars, like -digester and -betwixt, are 
needless).
