SAPUI5 Project - Missing persistence.xml

Question

Hi,
I have created a simple SAPUI5 application having an Employee form. The values should be saved in the HANA DB. As there are multiple ways to save the data in HANA, I am exploring the JPA based approach.
I am following the Container-Managed Persistence Example and able to create the project. Instead of Dynamic Web project, I have created SAPUI5 project and also changed the project facets as mentioned in the tutorial.
Now the problem is that I am not able to deploy the project on SAP HCP. It is giving me following error -
2014 09 04 07:45:24#+00#ERROR#unknown.jul.logger##anonymous#fs-watcher##p137653trial#jadyn#web##Unable to load Persistence Unit from EAR: /usr/sap/ljs/webapps/jadyn, module: file:/usr/sap/ljs/webapps/jadyn/WEB-INF/classes/.

Anyone has any idea on what wrong I am doing.  Please check the attached error log for more details. Thanks!

Actually yes - please get familiar with The SCN Rules of Engagement! In particular, don't push if you haven't received an answer after 3 hours or so.
Now, I am not sure how a UI5 project is exported and what it packages but I would recommend using a Dynamic Web project which is intended for Java web development and supports JPA. You can also have your HTML and JS static resources in it.
