Many SAP partners are interested in migrating the database layer of their non-SAP products into SAP HANA. I therefore have written a HANA migration guide on SCN: https://scn.sap.com/docs/DOC-38672 . The example project Mvnforum is a bit simple one which does not use any open source framework like Hibernate, struts etc. Furthermore, I have integrated HANA with the Hibernate framework and I have verified the correctness of this integration in two open source applications that use Hibernate. More details about this HANA-Hibernate integration will be published in SCN very soon.
