JPA can't find table

Question

I'm using JPA 2.0, Eclipselink 2.0, maven and weblogic 10.3.6. Here's my persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
    <persistence-unit name="certifications" transaction-type="JTA">
        <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
        <jta-data-source>jdbc/com/ni/ds_edata_soa_nontx</jta-data-source>
        <class>com.ni.apps.engineering.certification.entities.NicdsCliCertificationStg</class>
        <class>com.ni.apps.engineering.certification.entities.NicdsCliCertificationStgPK</class>
        <class>com.ni.apps.engineering.certification.entities.NicdsCliUpMapping</class>   
        <properties>                        
            <property name="javax.persistence.jdbc.password" value="ni"/>
            <property name="javax.persistence.jdbc.user" value="NI"/>
            <property name="javax.persistence.jdbc.driver" value="oracle.jdbc.OracleDriver"/>
            <property name="eclipselink.logging.level.sql" value="FINE"/>       
        </properties>       
    </persistence-unit>
</persistence>

This is my facade

    package com.ni.apps.engineering.certification.controller;

import java.util.List;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.persistence.PersistenceUnit;
import javax.persistence.TypedQuery;
import com.ni.apps.engineering.certification.entities.NicdsCliCertificationStg;
import com.ni.apps.engineering.certification.exception.CertificationException;
import com.ni.apps.engineering.certification.utils.CertificationConstants;

public class CertificationFacade {  

    @PersistenceUnit(unitName = "certifications")
    private EntityManagerFactory emf;

    public List<NicdsCliCertificationStg> getCertificationsByUpId(String upId)
            throws CertificationException {
        String stringQuery = new StringBuilder(
                "select c from NicdsCliCertificationStg c where c.id.contactsId = 1234").toString();
                //.append(upId).toString();
        try {
            emf = Persistence.createEntityManagerFactory("certifications");     
            EntityManager em = emf.createEntityManager();
            TypedQuery<NicdsCliCertificationStg> query = em
                    .createQuery(stringQuery, NicdsCliCertificationStg.class);
            return query.getResultList();
        } catch (Exception e) {
            throw new CertificationException(
                    CertificationConstants.INTERNAL_ERROR_MESSAGE, e);
        }
    }
}

When I try to run the app, this is the error I'm getting

Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.3.1.v20111018-r10243): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist

Error Code: 942
Call: SELECT CONTACTS_ID, PROFILE_ID FROM NI.NICDS_CLI_UP_MAPPING WHERE (PROFILE_ID = ?)
    bind => [1 parameter bound]
Query: ReadAllQuery(referenceClass=NicdsCliUpMapping sql="SELECT CONTACTS_ID, PROFILE_ID FROM NI.NICDS_CLI_UP_MAPPING WHERE (PROFILE_ID = ?)")

Any ideas why it can't find the table?

-EDIT- Adding the entity

Answer 1

The error was that the weblogic's datasource had a different combination of user and password than the one I need for the application's schema. If I find a way to force JPA to use a specific schema/user/password combination without changing the user in the datasource, I'll update this answer.

Answer 2

If you are using different user to test, then the user that is configured in the datasource

In the datasource Connection Pool config, go to advanced section

Type this in the "Init SQL" section (see the SQL word before the instruction, its needed)

SQL ALTER SESSION SET CURRENT_SCHEMA=DEVLPMT
