mysql database connector error windows

how to connect MYSQL 5.5 JDBC driver with BONITA 7.9

While connecting MYSQL driver I get following error.
"for unserializable output you have to transform to serialized object using output expression window"

Create mysql connection in Windows with community 7.0.3 and 7.1 gives me the error: org.bonitasoft.console.common.server.utils.DefaultTenantIdException

I have followed the documentation to setup Bonitasoft's bundle to use mysql, but when I go to http://localhost:8080/bonita/portal/homepage I see a big red dot with the number 500 and the message "org.bonitasoft.console.common.server.utils.DefaultTenantIdException" instead of the portal page
