jpa - java.lang.IllegalStateException: Unable to retrieve EntityManagerFactory for unitName CarLocPU -
i'm beginning java ee netbeans 8.1, glassfish 4.1 , apache derby (included in glassfish).
for purpose i'm calling put , store car data attributes.
but simple facade returns "java.lang.illegalstateexception" whereas i'm seeing no mistakes in class files.
here simple entity of model.car basic getters , setters :
@entity @table(name = "car") public class car implements java.io.serializable { @id @generatedvalue(strategy = generationtype.sequence) private integer id; private string brand; private string model; private string year; private string energy; private string hp; private string tp; private byte[] picture; here "facade" entity store data in apache derby :
@stateless public class carfacade extends abstractfacade<car> { @persistencecontext(unitname = "carlocpu") private entitymanager em; @override protected entitymanager getentitymanager() { return em; } public carfacade() { super(car.class); } } i'm having lot of trouble debugging following exception since simple short part of code , should works fine. moreover, stacktrace doesn't show breaking point in java se.
here exception stacktrace :

edit :
here structure of project.
and here persistence.xml content, application named "carloc".
<?xml version="1.0" encoding="utf-8"?> <persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"> <persistence-unit name="carlocpu" transaction-type="jta"> <jta-data-source>java:app/jdbc/carloc</jta-data-source> <exclude-unlisted-classes>false</exclude-unlisted-classes> <properties/> </persistence-unit> </persistence>
if using jpa outside of ejb container, need declare jpa <provider> in persistence.xml.
by default glassfish uses eclipselink jpa provider. assuming don't want change this, want change persistence.xml declare eclipselink jpa provider:
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0"> <persistence-unit name="carlocpu" transaction-type="jta"> <provider>org.eclipse.persistence.jpa.persistenceprovider</provider> <exclude-unlisted-classes>false</exclude-unlisted-classes> <properties> <property name="eclipselink.target-database" value="derby"/> <!-- jdbc connection properties --> <property name="eclipselink.jdbc.driver" value="org.apache.derby.jdbc.clientdriver"/> <property name="eclipselink.jdbc.url" value="jdbc:derby://localhost:1527/mydbname;create=true;"/> <property name="eclipselink.jdbc.user" value="app"/> <property name="eclipselink.jdbc.password" value="app"/> </properties> </persistence-unit> </persistence>
