Hi Alex, I've created a simple project that shows how to use JPA in Karaf although it uses OpenJPA as the JPA provider:
https://github.com/jtkb/jpatest Hopefully it will be straight forward enough for you to get to grips with JPA in an OSGi environment. Kerry On 29/05/18 19:54, alex09 wrote:
Hi there, being new to OSGi, I have difficulties getting demos/examples/tutorials to run (esp. with JPA) with Apache Karaf 4.2. I tried all these resources: * Apache Aries 2.7 JPA examples: https://github.com/apache/aries-jpa/tree/master/examples (also user documentation is not accurate for the current Karaf versions) * Tutorials at http://karaf.apache.org/documentation.html#tutorials, which don't work as liquid-reality.de has not been available for weeks now (I found some of them here, but still they don't work: https://github.com/cschneider/Karaf-Tutorial) * Apache Aries 2.7: The Blog Example: http://aries.apache.org/modules/samples/blog-sample.html * Hibernate Demos: https://github.com/hibernate/hibernate-demos/tree/master/hibernate-orm/osgi (also reflecting the outdated user documentation) * also the Entwicklerpress 143 book "OSGi Entwicklung" and Enterprise OSGi in Action All without success, the sample are really dated and there is a lot more to do than just simple changes - this is difficult for someone coming new to this topic. I'd certainly volunteer for helping with this, but as there is no starting point currently, this is complicated. So my question is: are there any plans to create a new, sound description/documentation/tutorial/example for JPA/Hibernate on Apache Karaf 4.x? Or isn't this supposed to work anymore as there are better practices for persistence in OSGi? Thanks & Best Alex -- Sent from: http://karaf.922171.n3.nabble.com/Karaf-User-f930749.html
