Question

I am trying to run a JSP file deployed to Amazon’s Beanstalk, which uses DataNucleus to connect to RDS, and am getting the following error:

javax.jdo.JDOFatalDataStoreException: No suitable driver found for jdbc:mysql://mydbblahblah.rds.amazonaws.com:3306/mydb?autoReconnect=true

root cause

java.sql.SQLException: No suitable driver found for jdbc:mysql://bmydbblahblah.rds.amazonaws.com:3306/mydb?autoReconnect=true
    java.sql.DriverManager.getConnection(DriverManager.java:640)
    java.sql.DriverManager.getConnection(DriverManager.java:200)

Now I have the MySQL connector files in the classpath (it is at WebContent/WEB-INF/lib/mysql-connector-java-5.1.15-bin.jar, so this should work.

I have also confirmed that if I remove the library from there, I get the “com.mysql.jdbc.Driver not found on CLASSPATH” error.

Here is what my datanucleus.properties file looks like this:

javax.jdo.PersistenceManagerFactoryClass=org.datanucleus.api.jdo.JDOPersistenceManagerFactory

javax.jdo.option.ConnectionDriverName=com.mysql.jdbc.Driver
javax.jdo.option.ConnectionURL=jdbc:mysql://bmydbblahblah.rds.amazonaws.com:3306/mydb
#javax.jdo.option.ConnectionURL=jdbc:mysql://localhost:3306/mydb?autoReconnect=true
javax.jdo.option.ConnectionUserName=user
javax.jdo.option.ConnectionPassword=pwnothere

All of this works on my local Tomcat connecting to RDS. It only fails when running on Beanstalk.

Any ideas what might be causing this issue?

Thanks

So we downgraded to DataNucleus 2.0 without any other changes, and the issue disappeared. Sad, but it worked. I cannot recommend newer versions of DataNucleus with MySQL.
