I m having problem running a class which should create a table and insert one row of data.

when I click run in eclipse
it say no persistence provider.
I installed eclipselink under help > install new software
and run the class again. it said the same thing.
what did I do wrong? did I miss anything not installed?
I post the persistence.xml for your checking.

Ensure that the eclipselink.jar is no your classpath.

EclipseLink.jar needs to be on your classpath as well as any other libraries you wish your code to use.
http://wiki.eclipse.org/FAQ_How_do_I_add_an_extra_library_to_my_project's_classpath%3F

You can should be able to search for demos that walk through step by step how to setup JPA/EclipseLink projects in Eclipse.

Chris
