please shed light

edit

now have deleted persistance.xml , updated code work without persistance.xml still same error.

@bean @autowired public entitymanagerfactory entitymanagerfactory(datasource bcdatasource) {     eclipselinkjpavendoradapter vendoradapter = new eclipselinkjpavendoradapter();     vendoradapter.setdatabaseplatform("org.eclipse.persistence.platform.database.mysqlplatform");     vendoradapter.setgenerateddl(true);     vendoradapter.setshowsql(false);      localcontainerentitymanagerfactorybean factory = new localcontainerentitymanagerfactorybean();      factory.setpackagestoscan("com.pixieuniverse.nostalgia.model.entity");     factory.setjpavendoradapter(vendoradapter);     factory.setdatasource(bcdatasource);      properties properties = new properties();      properties.setproperty("eclipselink.weaving", "false");      factory.setjpaproperties(properties);     factory.afterpropertiesset();      return factory.getobject(); } 

any hints please?
