Description nthompson 2008-08-21 22:06:37 UTC 
If entity classes are located in external JAR files instead of the current NetBeans project then the RESTful Web 
Services from Entity Classes wizard cannot find the persistence unit files and it stops with the message "Current 
project has no persistence units. Please use New Persistence Unit wizard to create one."  The developer has two 
workarounds: (1) either use the New Persistence Unit wizard to create a persistence.xml file assuming that he/she has 
the knowledge to do so, or (2) manually merge the contents of the various individual persistence.xml files from each 
of the external jar files into a single persistence.xml file for the current project.
Comment 1 nthompson 2008-08-21 22:18:32 UTC 
This phenomena can be demonstrated by building the two NetBeans projects that are associated with the tutorial, "Using 
Java Persistence API Within a Visual Web JSF Application." The tutorial builds a visual web application (named 
TestWebApp) that binds a visual component to a JPA entity class that is packaged in another project's jar file (the 
other project is named TestModelApp).

To reproduce this problem, follow the tutorial through to completion and confirm that the visual web application 
displays the User table contents when it is run. After running the tutorial, use the "Restful Web Services from Entity 
Classes Wizard" in the TestWebApp project to build the web services. It will be observed that the wizard will not be 
able to find a persistence unit and will stop prematurely. A workaround can be applied by copying the persistence.xml 
file from the TestModelApp project's "src/META-INF/" directory to the TestWebApp project's "src/conf/" directory. If 
the RESTful Services wizard is run again, it will find the persisence.xml file that was copied from the external jar 
file and will successfuly complete the creation of the REST services.

it may be consider as a duplicate of #101556 or at least it's related.
Comment 3 Denis Anisimov 2011-10-07 06:23:10 UTC 
I'm able to reproduce it.
Current wizard REST from Entities uses the same UI that is JPA 
Controller from entities.
It has the same problem.
Comment 4 Sergey Petrov 2011-10-10 10:02:38 UTC 
As it's said current wizard is the sae as in persistence area, and it's unfortunately just isn't supported so far to use/recognize pu from jars.
