Centera called by EJB3 application

Are there any code samples how to properly handle the java objects of the sdk in a ejb3 application? Under 'best practices' gets recommended to use multithreading with around 10 threads to get a good performance. In a EJB-application there might be more than 10 sessions which intend to access centera at the same time. How to control there not to reach the connection limit? Resource sharing, but how to implement? Is there a Java Connector API (JCA) implementation for resource handling from a Java application server?

Following the javadoc for each FPPool object a new connection gets established. Creating and closing such an object in each session will probably not have a good performance. Are there any recommendations or 'How to's' ?
