Is it possible to make JPA use SSL for it's connections. I don't know very much about JPA, so I can't provide many details about what version and provider I'm using, but here is a stripped version of my persistence.xml file. Is there a property you can add that makes it use secure connections?

It is not anything JPA specific, just about adding arguments to JDBC connection String. Assuming that everything else is correctly set, then adding this should be enough:
?useSSL=true&requireSSL=true
If SSL connection in general is not working, then this page provides more information: MySQL 20.3.4.5. Connecting Securely Using SSL
I found this was useful in EclipseLink 2.5.0 to pass properties through to the JDBC driver:
<property name="eclipselink.jdbc.property.my_property_name" value="my_value" />
This is driver specific, but in your case it would be:
<property name="eclipselink.jdbc.property.useSSL" value="true" />
<property name="eclipselink.jdbc.property.requireSSL" value="true" />

Very anxious！！！！！！！！
First off I'd suggest removing the custom main() as there's nothing specific you're doing there that can't be achieved with Maven war packaging.
Secondly, I think your yaml is missing the swarm: as the first level, and you can also remove the JDBC Driver creation and let WF Swarm do that for you. For that I switched the driver-name to mysql, which will work so long as the JDBC driver dependency for MySQL is part of the project.

I have a Java SE 1.7 standalone application.
It uses Hibernate 4.3 final and JPA 2.1 to retrieve thousands of rows from a db2 zos database.
I have a multiple tables tor retrieve related rows from.
All I am testing currently is retrieving the Parent Table rows then two related children table rows.
One child table has a one to one relationship the other has a One to Many relationship.
I can retrieve 2000+ rows from the main parent table OK, I hold these rows in a an ArrayList
Then I attempt to retrieve the children table rows using the Ids held in my array list.
This is when I generate the following exception:-
***** Out of Package Error Occurred (2015-01-14 15:55:29.935) *****
Concurrently open statements:
1. SQL string: SELECT .....

My JPA entity classes do not have any Mappings between them e.g. #ManyTo or #OneTo

How can I get JPA and/or hibernate to "close" the open statements?
My peristance file is:

</persistence-unit>
</persistence>
And I am quiet sure that it is the only configuration file in my project because I tried to put wrong password and I got the expected error on connection.
I want to change semap db name to any other but in vain.
Is there any other configuration that I don't know?
UPDATE
The real problem is that my application is still working with semap db (the old one)
I'm writing a database synchronization tool for existing databases. One of the requirement is to validate the entities with the database schema. The program has to be aware of any database changes (like adding new columns to the database). I'm planning on using Hibernate for this project.
Is there anyway Hibernate can validate the difference between the entity and the table in the database?
Can Hibernate output SQL script so I can review the SQL script before running it to update the target database?
Yes hibernate can output the SQL in the logs.
You need to set the : - <property name="hibernate.show_sql" value="true"/>
but SQL generated by the server is little messy so you have to modify the column name as per your database table.
please have a look at the following XML of my project with the hibernate

I added this line to my MANIFEST.MF:

I can now confirm that it's a bug in EclipseLink. The work around to your problem is to either get hold of EntityManagerFactory using JNDI lookup or #PersistenceUnit instead of doing Persistence.createEntityManagerFactory().
1) It looks like you are trying to use OSGi/JPA from your WAB. Correct?
2) Can you tell if you have installed any new eclipselink bundles in your system? If so, what are they?
3) Can you provide stack trace?
