In Android project I'm using spring REST lib for call jax-rs services on Apache Tomcat/7.0.32 . For database communication I'm using hibernate 3.0.
Sometimes API return error: org.hibernate.exception.JDBCConnectionException: could not execute query
I think that problem is in hibernate SessionFactory.
Want to know how to configure tomcat web service to use in enterprise enviroment. How to configure hibernate SessionFactory to handle more requests.

UPDATE:
Solution for exception :org.hibernate.exception.JDBCConnectionException: could not execute query was sql-error-0-sqlstate-08s01.html
You can use JTA as suggested in the documentation: http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/architecture.html#architecture-current-session
If you are looking for something "more enterprise" I would suggest using a SessionManager and a connection pooling. This is going to give you more options and flexibility to your application. Spring offers some nice features in this regards.
