If you download from here http://sourceforge.net/projects/datanucleus/files/datanucleus-accessplat form/3.0.1/datanucleus-accessplatform-rdbms-3.0.1.zip/download you will get a zip file that contains all the bundles you need (and more).
>From those you will need to install: datanucleus-api-jpa-*.jar datanucleus-core-*.jar datanucleus-rdbms-*.jar In our case we used JDO so we included jdo-api-*.jar, look at the site for what you need for JPA (maybe it's the geronimo-jpa*.jar?). Should be in the deps folder of the zip file. I think for MySQL you would have to run that outside OSGi unless you know of a Java port that runs in OSGi. When configuring Data Nucleus you just give it the connection URL to the database. We used H2 ourselves as that can be embedded in OSGi. I'm not really familiar with JPA so I can't help you there. I imagine the Data Nucleus site has some examples.

I want to use the Data Nucleus JPA implementation. Can you give more more details? Such as which OSGi Data Nucleus bundles should I install? (I work with MySQL) How to configure the MySQL JDBC in OSGi Felix? is it also an OSGi bundle? Which transaction type should I use? JTA or RESOURCE_LOCAL ? Can you show me a client example that consumes the JPA service?
