my pu in persistence.xml looks this:
<persistence-unit name="nosql_pu" transaction-type="jta"> <provider>org.eclipse.persistence.jpa.persistenceprovider</provider> <exclude-unlisted-classes>false</exclude-unlisted-classes> <properties> <property name="eclipselink.target-database" value="org.eclipse.persistence.nosql.adapters.mongo.mongoplatform"/> <property name="eclipselink.nosql.connection-spec" value="org.eclipse.persistence.nosql.adapters.mongo.mongoconnectionspec"/> <property name="eclipselink.nosql.property.mongo.port" value="27017"/> <property name="eclipselink.nosql.property.mongo.host" value="localhost"/> <property name="eclipselink.nosql.property.mongo.db" value="dev"/> <property name="eclipselink.logging.level" value="finest"/> </properties> </persistence-unit> my nosql entity class;
@namedqueries({ @namedquery(name = "comment.findall", query = "select e comment e"), @namedquery(name = "comment.findbypk", query = "select e comment e e.id = :id"),}) @entity @nosql(dataformat = dataformattype.mapped) public class comment implements serializable { // serial------------------------------------------------------------------- private static final long serialversionuid = 1l; // variables---------------------------------------------------------------- @id @generatedvalue @field(name="_id") private string id; @basic private long created; @basic private string commenterid; @basic private string comment; // constructors------------------------------------------------------------- // getters------------------------------------------------------------------ // setters------------------------------------------------------------------ } im using ctm im calling pu in stateless session bean;
@stateless public class ticketdaoimpl implements ticketdao { @persistencecontext(unitname = "nosql_pu") private entitymanager em; } ive been following eclipselink guide can't find pertaining this.
the problem persistence unit. default entity classes included, both nosql , sql entities being passed both sql , nosql persistence units. solution specify entities inside persistence.xml persistence unit.
<persistence-unit name="dastrax_nosql_pu" transaction-type="jta"> <provider>org.eclipse.persistence.jpa.persistenceprovider</provider> <class>declare_your_entity_1</class> <class>declare_your_entity_2</class> <exclude-unlisted-classes>false</exclude-unlisted-classes> <properties> <property name="eclipselink.target-database" value="org.eclipse.persistence.nosql.adapters.mongo.mongoplatform"/> <property name="eclipselink.nosql.connection-spec" value="org.eclipse.persistence.nosql.adapters.mongo.mongoconnectionspec"/> <property name="eclipselink.nosql.property.mongo.port" value="27017"/> <property name="eclipselink.nosql.property.mongo.host" value="localhost"/> <property name="eclipselink.nosql.property.mongo.db" value="dev"/> <property name="eclipselink.logging.level" value="finest"/> </properties> </persistence-unit>
