Hi, if you have such a name during JNDI lookup osgi:service/** javax.sql.DataSource/(osgi.**jndi.service.name<http://osgi.jndi.service.name/> =osgi:**service/javax.sql.DataSource/(**osgi.jndi.service.name<http://osgi.jndi.service.name/> =ch.**eugster.herakles.persistence.**data.source) you will have the necessity to use OSGI based JNDI provider.
If you are in a JEE container I am not sure it is possible. In simple J2SE aries-jndi does that. Did you drop the aries jndi bundle also into your OSGI container? As it has to start before your persistence unit is loaded the start level of jndi bundle should be low.
