How to configure cloud datasource for MySQL on Bluemix? - mysql

Question

How do I create a datasource for cloud in MySQL when running on Bluemix? If there are any Java configuration examples available, please share. How do I make Hibernate create tables and why do I get this error?

Finally I got It working I just added an environment variable to activate cloud profile in manifest.yml and removed extends AbstractCloudConfig as it was also searching for mongodb .After these changes It Started working and now I can run spring mvc on blue mix.
