I think that could be bluemix update auto-config... any idea? ps: previously I can run without problems , but now i can't...

After some days without changes , I push a new war...and now a got that error

The Liberty buildpack automatically configures the Data Source when a recognized relational database service is bound (DB2, mysql, etc.). The JNDI name would be "jdbc/". So you can use that JNDI name to look up the data source in the code or in the JPA configurations/annotations. Read more about this auto-configuration feature in the Liberty buildpack: https://www.ng.bluemix.net/docs/starters/liberty/index.html#automaticconfigurationofboundservices
