Hi Guys,

I would like to ask some help regarding the issue below.

DataNucleus.Persistence : Error : Could not find API definition for name "JDO". Perhaps you dont have the requisite datanucleus-api-XXX jar in the CLASSPATH?

Error : Could not find API definition for name "JDO". Perhaps you dont have the requisite datanucleus-api-XXX jar in the CLASSPATH?

org.datanucleus.exceptions.NucleusUserException: Error : Could not find API definition for name "JDO". Perhaps you dont have the requisite datanucleus-api-XXX jar in the CLASSPATH?

I used SpringBoot and integrated the DataNucleus.
it is working fine when using this command line 

mvn clean package spring-boot:run

The message is very clear. You seemingly don't have the jar `datanucleus-api-jdo.jar` in the CLASSPATH. That jar contains a file `plugin.xml` and if it isn't found then features cannot work.

Same problem here when testing DN 4.x AND 5.x!!

Everything works fine with DN 2.1

And as the reply to the original post says, you don't seem to have a jar in your classpath. Consequently it is for you to DEBUG why you don't have it since only you can see your setup
