The abstract schema type is unknown - jpa

Question

I'm using Spring 3.2.3, JPA 2.1, JUnit 4.11. I'm trying to run a junit test and I keep getting the abstract schema type is unknown error. Here is my entity (truncated for space, it has all the getters and setters):
#Entity
#Table(name = "WEB_PROFILES")
public class TestWebProfile implements Serializable {
private static final long serialVersionUID = 1L;
#Transient
private String forward;
#Column(name = "ACCESS_FLAG")
private String accessFlag;
#Temporal(TemporalType.DATE)
#Column(name = "ACCESS_FLAG_UPD_DATE")
private Date accessFlagUpdDate;
#Column(name = "ACCESS_RESET_INTERVAL")
private BigDecimal accessResetInterval;
#Column(name = "ACCOUNT_TYPE")
private String accountType;
#Column(name = "CREATED_BY")
private String createdBy;
#Column(name = "E_MAIL")
private String eMail;
#Column(name = "FAILED_LOGIN_ATTEMPTS")
private BigDecimal failedLoginAttempts;
#Column(name = "FIRST_NAME")
private String firstName;
#Temporal(TemporalType.DATE)
#Column(name = "FROI_ACCESS_APPROVE_DENY_DATE")
private Date froiAccessApproveDenyDate;
#Column(name = "FROI_ACCESS_APPROVED_FLAG")
private String froiAccessApprovedFlag;
#Column(name = "FROI_ACCESS_REQUESTED")
private String froiAccessRequested;
#Column(name = "FROI_APPROVED_BY")
private String froiApprovedBy;
#Temporal(TemporalType.DATE)
#Column(name = "FROI_CONFIRM_EMAIL_SENT_DATE")
private Date froiConfirmEmailSentDate;
#Temporal(TemporalType.DATE)
#Column(name = "FROI_LETTER_SENT_DATE")
private Date froiLetterSentDate;
#Column(name = "LAST_LOGON_ADDR")
private String lastLogonAddr;
#Temporal(TemporalType.DATE)
#Column(name = "LAST_LOGON_DATE")
private Date lastLogonDate;
#Column(name = "LAST_NAME")
private String lastName;
#Column(name = "LAST_UPDATED_BY")
private String lastUpdatedBy;
#Column(name = "LAST_UPDATED_BY_NAME")
private String lastUpdatedByName;
#Column(name = "LAST_UPDATED_BY_SU_ID")
private BigDecimal lastUpdatedBySuId;
#Temporal(TemporalType.DATE)
#Column(name = "MAIL_SENT_DATE")
private Date mailSentDate;
#Temporal(TemporalType.DATE)
#Column(name = "MAINT_DATE")
private Date maintDate;
#Temporal(TemporalType.DATE)
#Column(name = "NEW_PIN_REQ_DATE")
private Date newPinReqDate;
#Column(name = "PASSWORD")
private String password;
#Transient
private String newPassword;
#Temporal(TemporalType.DATE)
#Column(name = "PASSWORD_UPD_DATE")
private Date passwordUpdDate;
#Column(name = "PHONE")
private String phone;
#Column(name = "PIN")
private String pin;
#Column(name = "POLICY_NUM")
private BigDecimal policyNo;
#Column(name = "PROFILE_CLASS_CODE")
private String profileClassCode;
#Temporal(TemporalType.DATE)
#Column(name = "PROFILE_REQ_DATE")
private Date profileReqDate;
#Temporal(TemporalType.DATE)
#Column(name = "PROFILE_UPDATE_DATE")
private Date profileUpdateDate;
#Column(name = "REMOTE_ADDR")
private String remoteAddr;
#Column(name = "SESSIONID")
private String sessionid;
#Column(name = "SUBSCRIBER_FLAG")
private String subscriberFlag;
#Column(name = "USER_ID")
private BigDecimal userId;
#Id
#Column(name = "USER_NO")
private BigDecimal userNo;
#Column(name = "USERNAME")
private String username;
My JUnit test:
#Test
public void testGetWebProfileByUsername() {
TestWebProfile wp = sso.getWebProfile("MARLENE");
System.out.println("name :" + wp.getFirstName());
System.out.println("last name :" + wp.getLastName());
}
My DAO implementation:
#Override
public TestWebProfile getWebProfile(String username) {
String sqlString = "select w from TestWebProfile w where w.username =:username";
return (TestWebProfile) getEntityManager()
.createQuery(sqlString, TestWebProfile.class)
.setParameter("username", username).getSingleResult();
}
After Googling for the past hour, the only culprit I found that seem to make sense was not having the #Id and #Column annotations, but I have those on the userNo variable. Any help that can be provided would be greatly appreciated!

Answer 1

Have a look at this. It gives some suggesstion for the same case http://java.dzone.com/tips/the-nasty-jpa-unknown-abstract

Answer 2

If you are using Java SE you have to add the fully qualified name of your entity class in persistence.xml, like so
<persistence-unit ...>
<class>your.custom.package.TestWebProfile</class>
</persistence-unit>
Omitting the package part may lead to your error.

Answer 3

Try adding inside your persistence-unit tag as follows:
<exclude-unlisted-classes>false</exclude-unlisted-classes>
For some reason in my case although I was listing all the classes inside my persistence unit using fully qualified names, eclipseLink didn't recognize them. Once added that line, it just works.
I was using:
Java SE 8
Maven Project
EclipseLink (Local not an application server)
Netbeans
