i have been spending week attempting integrate jpa / servicemix 4.5.1 / camel-jpa 2.10.4 / blueprint together. i'm using openjpa, not tied it. version of aries jpa used servicemix 0.3.0.
the stack trace cannot past is:

i've attempted forego using jndi , instead define data source directly in persistence.xml. causes classnotfoundexception in openjpa bundle, not importing mysql driver. i'd prefer define in camel-context.xml , prefer not re-bundle openjpa jar.
you need aries jndi features installed. helps call osgi services via jndi lookups. should missing piece.
