Thank you for your answer Georgi, I am going to read the OpenJPA's documentation.<br><br>Best regards<br>Rafael<br><br><div class="gmail_quote">2012/5/22 Georgi Naplatanov <span dir="ltr"><<a href="mailto:gosho@oles.biz" target="_blank">gosho@oles.biz</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">If your database schema is ready, you can use OpenJPA's reverse mapping tool [1] to generate your persistence classes. It works well, but you have to adjust class names for multi-column primary keys and add @Lob annotation for binary fields and do not forget to use build time enhancement.<br>
<br>
Using cache, database connection pool and prepared statements improve performance.<br>

Hi Rafael.<br>
<br>
You can use whatever suit your needs. OpenCms 8.x includes OpenJPA<br>
2.x as JPA provider, but it's possible to use other JPA providers<br>
(like Hibernate) as well.<br>
<br>
Best regards<br>

Hello list,<br>
<br>
I would like to connect to a schema in MySQL, not OpenCMS's schema,<br>
another one I have created.<br>
Can I do it or maybe I need to use Hibernate, JPA?<br>
<br>
Thank you.<br>
<br>
