In an effort to learn Hibernate (4.1) with Oracle Stored Procedures, I am trying to get an example to work that is as simple as I can make it:
1. No parameters passed in
2. SYS_REFCURSOR as the one return parameter

I'm getting an exception: "org.hibernate.exception.GenericJDBCException: Invalid column index" (see full stack trace below).
Searching for this online and experimenting with it for several days has been less than fruitful.
The Entity class works fine in other (non-stored procedure) contexts.
The stored procedure works fine when called from PL/SQL in Toad.
I am slightly concerned that the oracle portion of the stack trace indicates the setup is using the deprecated oracle.jdbc.driver classes when my setup is all for Oracle 10g.

Procedure
Code:
    CREATE OR REPLACE PROCEDURE IFC_OWNER.JPA_APPLICATION_R_TEST
    (    o_result_set OUT SYS_REFCURSOR  )
    AS
    BEGIN
        OPEN o_result_set FOR
        SELECT APPLICATION_ID, APP_COMMON_NM, APP_DESC, APP_URL FROM APPLICATION_R;
    END;
    /

xml call
Code:
    <sql-query name="oracleproccall" callable="true">
        <return alias="application_r" class="com.myco.entities.ApplicationR"/>
        <![CDATA[ call JPA_APPLICATION_R_TEST()   ]]>
    </sql-query>

java (Exception thrown at call to sqlQuery.getResultList())
Code:
public void run() {
   EntityManager entityManager = entityManagerFactory.createEntityManager();
   try {
      Query sqlQuery = entityManager.createNamedQuery("oracleproccall");
      List list = sqlQuery.getResultList();   
      <snip>   
   } catch (PersistenceException ex) {
      ex.printStackTrace();
   } finally {
      entityManager.close();
   }   
}

Entity class
Code:
/**
* ApplicationR generated by hbm2java
*/
@Entity
@Table(name="APPLICATION_R"
    ,schema="IFC_OWNER"
)
public class ApplicationR  implements java.io.Serializable {
     private int applicationId;
     private String appCommonNm;
     private String appDesc;
     private String appUrl;
     private Set<ApplicationFunctionR> applicationFunctionRs = new HashSet<ApplicationFunctionR>(0);

    public ApplicationR() {
    }
    public ApplicationR(int applicationId) {
        this.applicationId = applicationId;
    }
    public ApplicationR(int applicationId, String appCommonNm, String appDesc, String appUrl, Set<ApplicationFunctionR> applicationFunctionRs) {
       this.applicationId = applicationId;
       this.appCommonNm = appCommonNm;
       this.appDesc = appDesc;
       this.appUrl = appUrl;
       this.applicationFunctionRs = applicationFunctionRs;
    }
    @Id
    @Column(name="APPLICATION_ID", unique=true, nullable=false, precision=9, scale=0)
    public int getApplicationId() {
        return this.applicationId;
    }
    public void setApplicationId(int applicationId) {
        this.applicationId = applicationId;
    }
    @Column(name="APP_COMMON_NM", length=30)
    public String getAppCommonNm() {
        return this.appCommonNm;
    }
    public void setAppCommonNm(String appCommonNm) {
        this.appCommonNm = appCommonNm;
    }
    @Column(name="APP_DESC", length=50)
    public String getAppDesc() {
        return this.appDesc;
    }
    public void setAppDesc(String appDesc) {
        this.appDesc = appDesc;
    }
    @Column(name="APP_URL", length=100)
    public String getAppUrl() {
        return this.appUrl;
    }
    public void setAppUrl(String appUrl) {
        this.appUrl = appUrl;
    }
   @OneToMany(fetch=FetchType.LAZY, mappedBy="applicationR")
    public Set<ApplicationFunctionR> getApplicationFunctionRs() {
        return this.applicationFunctionRs;
    }
    public void setApplicationFunctionRs(Set<ApplicationFunctionR> applicationFunctionRs) {
        this.applicationFunctionRs = applicationFunctionRs;
    }
}

If I change the xml call to ? = call JPA_APPLICATION_R_TEST() per 4.1 doc section 18.2.2.1. Rules/limitations for using stored procedures
I get the following exception that doesn't seem like I'm on the right track at all:
ERROR: ORA-00900: invalid SQL statement

I found the issue. I was using a javax.persistence version of the Session and Query classes and not the org.hibernate version; javax.persistence does not support Oracle Stored Procedure calls while Hibernate does.
The difference is subtle without the import statements provided below.
The give away should have been the use of the sqlQuery.getResultList(). This is a JPA method call that does not exist in the Hibernate version of Query.

import import javax.persistence.Query;

Query sqlQuery = entityManager.createNamedQuery("oracleproccall");
List list = sqlQuery.getResultList();

The construct for using the Hibernate version is query.list() not query.getResultList():

Code:
   import java.util.Iterator;
   import java.util.List;
   import org.hibernate.Query;
   import org.hibernate.Session;
   import org.hibernate.SessionFactory;
   import org.hibernate.Transaction;
   import org.hibernate.cfg.Configuration;
   import com.myco.entities.ApplicationR
   
   
    private void anotherTest() {
        Configuration cfg = new Configuration();
        cfg.configure("hibernate.cfg.xml");
        SessionFactory sf = cfg.buildSessionFactory();
        Session s = sf.openSession();
        Transaction tx = s.beginTransaction();

        List<AppR> apps;
        Query namedQuery = s.getNamedQuery("oraclestoredproc");
        apps = namedQuery.list();
        apps = s.getNamedQuery("oraclestoredproc").list();
        Iterator<ApplicationR> iterator = apps.iterator();
        while (iterator.hasNext()) {
            ApplicationR app = (ApplicationR) iterator.next();
            System.out.print(app.getApplicationId() + " ");
            System.out.print(app.getAppCommonNm() + " ");
            System.out.print(app.getAppDesc() + " ");
            System.out.println(app.getAppUrl() + " ");
        }
        s.flush();
        tx.commit();
        s.close();
    }


Thanks to Jitu Ji and http://www.coderanch.com/t/466425/ORM/databases/Working-Hibernate-Call-Oracle-Stored

Note also: If you have an EntityManager object, you can get a org.hibernate.Session like this: Session s = entityManager.unwrap(Session.class);
