Re: [eclipselink-users] EclipseLink JPA in z/OS batch runtime

#1) The document you referenced is using a type 2 JCC driver (which uses C-compiled binaries), where a type 4 JCC driver is completely Java and a bit more portable.  Are you sure you wouldn't prefer to use type 4?  DeveloperWorks has a good article that goes into depth about the various DB2 driver types: http://www.ibm.com/developerworks/data/library/techarticle/dm-0512kokkat/


Yes, this is fine, the software will have a dependency for other reasons, so this doesn't add another portability problem...

The trick was to set the property "javax.persistence.jdbc.url="" in the persistence.xml.
This causes EclipseLink to call into DriverManager.getDonnnection() with above URL/connection string and user name and password set to null.
Then a successful connection could be established.

#2) Looks like you already got it covered with Bug 462828.

Yes, I did look into the problem today and found the culprit.

With kind regards

Hi,

I currently try to run a Java program in the z/OS batch runtime with Eclipselink as JPA provider. The program is basically a Java SE programming but the database connection is managed by the batch container.

Two questions/notices:
1.) How to get EclipseLink to use DriverManager according to this document:
http://www.redbooks.ibm.com/redbooks/pdfs/sg248116.pdf
See chapter 2.6.3.

With my configuration eclipse link seems to complain a missing config with URL, user and password being null. Any ideas?


2.) There seems to be a bug in some component regarding file encoding.

When running with file.encoding=IBM-273 the javax.persistence api (dependency via maven eclipselink jpa 2.6.0) fails to load the  eclipse jpa service provider. According to the JavaDoc of the ServiceLoader class, the services file needs to be in utf-8, so the eclipse link jpa jar file seems to be correct.

Any ideas in which component the error may resides?

With kind regards
Thomas
