java.sql.SQLException: Closed Resultset: getLong

I get data from Oracle, using JDBC and ojdbc7.jar library. My dataSource:
<bean id="myDataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
<property name="url" value="${oracle.url}"/>
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
<property name="username" value="${oracle.user}"/>
<property name="password" value="${oracle.password}"/>
<property name="maxTotal" value="20"/>
<property name="maxIdle" value="10"/>
<property name="maxWaitMillis" value="-1"/>
</bean>
My code:
public List<Link> getTerminalDevices(final int numbersMonths, final Long initServiceId, final List<Long> switchableServices) throws Exception {
final List<Link> result = new ArrayList<>();
try (final Connection cnn = myDataSource.getConnection();
final OracleCallableStatement stm = cnn.prepareCall(sql).unwrap(OracleCallableStatement.class)) {
stm.setPlsqlIndexTable(1, switchableServices.toArray(), switchableServices.size(), switchableServices.size(), OracleTypes.BIGINT, 0);
stm.registerOutParameter(2, OracleTypes.CURSOR);
stm.setLong(3, initServiceId);
stm.setInt(4, numbersMonths);
stm.execute();
try (final ResultSet rs = stm.getCursor(2)) {
while (rs.next()) {
result.add(new Link()
.id(rs.getLong(1))
.name(rs.getString(2))
.date(rs.getTimestamp(3)));
}
}
} catch (Exception ex) {
throw ex;
}
return result;
}
This code run in 5 Threads. Sometimes, once from a time I have an error:
java.sql.SQLException: Closed Resultset: getLong
at oracle.jdbc.driver.GeneratedScrollableResultSet.getLong(GeneratedScrollableResultSet.java:539) ~[ojdbc7.jar:12.1.0.1.0]
The error is not constant, and manifests itself under unclear conditions.
What's wrong? I don't understand this error, I correctly process connections, I'm using try-with resources. I can't close resultset!
UPDATE:
I conducted an investigation and found that the problem in this line:
final OracleCallableStatement stm = cnn.prepareCall(sql).unwrap(OracleCallableStatement.class)
If I make like this:
try (final Connection cnn = oracleDatasource.getConnection();
final CallableStatement originalCs = cnn.prepareCall(sql)) {
OracleCallableStatement stm;
if (originalCs instanceof OracleCallableStatement) {
stm = (OracleCallableStatement) originalCs;
} else {
DelegatingCallableStatement tomcatCs = (DelegatingCallableStatement) originalCs;
stm = (OracleCallableStatement) tomcatCs.getInnermostDelegate();
}
It,s work correct. Who has any thoughts on this? Why unwrap don't work correctly?

Hibernate, nested transactions not supported

I have a trouble when running my web application that tries to get all the information from the table snowboard and put it in a list which I will then print out in the xHtml. But I get this exception down below.
org.hibernate.TransactionException: nested transactions not supported
The thing is that I have no clue why this exception happens so would appreciate some explanation. Also if you find any trouble in the code that would be fantastic.
This is the exception that I get.
HibernateUtil
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
// Create the SessionFactory from standard (hibernate.cfg.xml)
// config file.
sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Log the exception.
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
SnowHelper, HelperClass
public class SnowHelper {
Session session = null;
public SnowHelper() {
this.session = HibernateUtil.getSessionFactory().getCurrentSession();
}
public List getSnowboards() {
List<Snowboard> snowboardList = null;
try {
Transaction tx = session.beginTransaction();
Query q = session.createQuery("from Snowboard");
snowboardList = (List<Snowboard>) q.list();
} catch (Exception e) {
e.printStackTrace();
}
return snowboardList;
}
}

SnowboardBean, ManagedBean class
#Named(value = "snowboardBean")
#Dependent
public class SnowboardBean {
private List<Snowboard> snowList;
private SnowHelper snow;
/**
* Creates a new instance of SnowboardBean
*/
public SnowboardBean() {
snowList = new ArrayList<>();
snow = new SnowHelper();
snowList = snow.getSnowboards();
}
/**
* #return the snowList
*/
public List<Snowboard> getSnowList() {
return snowList;
}
}

In this bit here.. commit your transaction
Transaction tx = session.beginTransaction();
Query q = session.createQuery("from Snowboard");
snowboardList = (List<Snowboard>) q.list();
tx.commit();
Otherwise you simply open a new transaction without closing it every time you invoke this method.. eventually one of them is opened while some other is not commited yet.
If you were using 'container managed transactions' (provided by Spring of EJB's) you would not have to worry about explicitly committing your transactions. Here you are using 'extended transaction management' and you have to take care of that yourself.

Hibernate get data .list() depricated and table not mapped. what to do?

I saw nearly all questions and answers for this on stackoverflow, but all answers are the same. That you should use something like this Query query = session.createQuery("from theme").list();
but .list() is depricated and I can´t use it anymore.
So the first Question is, what should I use instead of .list()and why I get this exeption java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: theme is not mapped [from theme]
Query Method
public ObservableList<String> getThemes(){
ObservableList<String> obsList = FXCollections.observableArrayList();
SessionFactory factory = new Configuration()
.configure("hibernate.cfg.xml")
.buildSessionFactory();
Session session = factory.getCurrentSession();
try {
session.beginTransaction();
Query query = session.createQuery("from theme"); // why not mapped
//cant use .list()?
session.getTransaction().commit();
System.out.println("query " + query);
} catch (Exception e) {
e.printStackTrace();
}finally{
session.close();
}
return obsList; // nothing at the moment

this.theme_name = theme_name;
}
public mapTheme(String theme_name) {
super();
this.theme_name = theme_name;
}
public mapTheme(){
}
}
what can I do?

The table name used in the query is not the name of the table in database, it should be the name of the entity class.
In this case you must use
Query query = session.createQuery("from mapTheme");
instead of :
Query query = session.createQuery("from theme")

Hibernate : Data stored in database without commiting

I'm using hibernate to add my objects into the database.
When I call sessionCacti.save(Object object) it stores the object to database while the object shouldn't not be stored because I didn't commit the changes and I use a non auto-commit mode.
Here is the file of the configuration of hibernate
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration SYSTEM
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>

<property name="hibernate.connection.driver_class">

</property>
<property name="hibernate.current_session_context_class">thread</property>
<!-- pcac is the database name -->
<property name="hibernate.connection.url">
jdbc:mysql://uaeipvm1:3307/pcac?zeroDateTimeBehavior=convertToNull
</property>
<property name="hibernate.connection.username">
myadmin
</property>
<property name="hibernate.connection.password">

<mapping resource="HostTemplate.hbm.xml" />
<mapping resource="HostTemplateGraph.hbm.xml" />
<mapping resource="Settings.hbm.xml" />
</session-factory>
</hibernate-configuration>
And this is my program :
public class SynchroCacti {
public static Map<String,Host> hosts = new HashMap<String, Host>();
private static SessionFactory factoryDerbi,factoryCacti;
private static Transaction tx=null;
private static Session sessionDerbi,sessionCacti;
public static List<Equipment> derbiEquipments;
private static List<HostTemplate> hostTemplates;
private static List<Settings> settings;
private static int nbNewHosts = 0;
private static int initialNbCactiHost,initialNbDerbiEqpts;
public static void initializeData ()
{
try{
factoryDerbi = new Configuration().configure("/hibernate_derbi.cfg.xml").buildSessionFactory();
factoryCacti = new Configuration().configure("/hibernate_cacti.cfg.xml").buildSessionFactory();
sessionDerbi = factoryDerbi.openSession();
sessionCacti = factoryCacti.openSession();
tx = sessionCacti.beginTransaction();
}catch (Throwable ex) {
logErrorsInProgram.error("Failed to create sessionFactory object." + ex);
throw new ExceptionInInitializerError(ex);
}
//Store tables of the database in these lists
derbiEquipments = sessionDerbi.createCriteria(Equipment.class).list();
List<Host> cactiHosts = sessionCacti.createCriteria(Host.class).list();
hostTemplates = sessionCacti.createCriteria(HostTemplate.class).list();
settings = sessionCacti.createCriteria(Settings.class).list();
//Initialize the hash map of hosts
Iterator<Host> it = cactiHosts.iterator();
while (it.hasNext())
{
Host actual = it.next();
hosts.put(actual.getDescription(), actual);
}
//Initialize values of initialNbCactiHost and initialNbDerbiEqpts from sizes of lists
initialNbCactiHost = hosts.size();
initialNbDerbiEqpts = derbiEquipments.size();
}
public static void addHostToDatabase (Host host)
{
nbNewHosts++;
try{
sessionCacti.save(host);
}catch (ConstraintViolationException e) {
if (tx!=null) tx.rollback();
}finally { //We don't close session
}
}
public static void main(String[] args) throws HibernateException, SQLException, ParseException {
initializeData();
Host host = createHost(derbiEquipments.get(0));
addHostToDatabase(host);
}
}
I don't want to save data until I execute tx.commit();
Thanks.

Expected positional parameter count: 1, actual parameters: []

I am getting this below exception when I am trying to execute a Stored procedure using HIbernate from DaoImpl Class.
I am not sure of what is wrong ..I tried all the ways to fix it but did not resolve the issue.
Could anyone please help me ,figure out whats wrong with the code or the mapping file.
The more I am trying to fix ,something the more exceptions I am getting.. I am connectuing to Oracle 9i DB.
I am struggling on this from really 2 weeks ending up no where.. can anyone please help me fix this issue.

You are missing to set the ? parameter which is a so called positional parameter. In contrast to named parameters like :foo
When you have some SQL you must also ensure not to have any Question Marks inside comments! That's what I just ran into. Same holds for : in comments, especially if they are followed by a space.
