I got this exception during a select "get" query loop.
Can you tell me how to avoid this?

I found that there was just one connection during this exception.
This is the Dao:
#Autowired
private SessionFactory sessionFactory;
public Session getSession(){
return sessionFactory.getCurrentSession();
}
public <T> T get(Class<T> classe, Serializable id) throws Exception {
if(id==null) return null;
T obj = (T) getSession().get(classe, id);
return obj;
}
This is app configuration:
<bean id="dataSource" class="com.cin.web.DataSourceSelector" />
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan">
<list>
<value>com.cin.db.entity</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.bytecode.use_reflection_optimizer">false</prop>
<prop key="hibernate.cglib.use_reflection_optimizer">true</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>

<prop key="hibernate.flushMode">always</prop>
</props>
</property>
<property name="mappingResources">
...
This is the database selector:
public class DataSourceSelector extends DriverManagerDataSource {
private String catalog;
private static Logger logss = Logger.getLogger(DataSourceSelector.class);
public String getCatalog(){
return catalog;
}
public DataSourceSelector(){
super();
String adb=DbConnector.getActiveDb();
if(!StringUtils.isBlank(adb)){
setDriverClassName("com.mysql.jdbc.Driver");
catalog=adb;
setUrl("jdbc:mysql://localhost/"+catalog);
logss.info("Selezionato DB: "+catalog);
setUsername("cin_java");
setPassword("password");
}
}
}
And the query loop is very simple and has something like this called >20000 times
dao.get(Entitiy.call,id)
I tried to add session.flush() session.clear() but I still get that error after 16000 query.
By your updated post I analyse that may be hibernate not releasing database connections after returning result. Because of which DB server getting into huge load.
I will suggest :
-Use session.flush(); and session.clear() after session.get(Entity.class, id);
-As you set you are doing session.get(Entity.class, id); in loop check you are not creating SessionFactory everytime.Implement an class which provide an static SessionFactory.
-Try to implement connection pooling with c3p0 or any think else.
Update(Related to class which provide an static SessionFactory)
When you do any transaction/operation with DB using hibernate you will need an session this session is responsible for DB state,operation (CRUD). You will get session from an SessionFactory which is created by reading hibernate configuration like hibernate.cfg.xml.
To build sessionFactory we use SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); if you call this code in a loop then this will trouble you more.
My idea is to create an class which will have static SessionFactory which will get created at the time of spring context loading using DI.
plz got to My answer to this post where i post code for HibernateHelper.java with HibernateHelper_DI.xml which will create static sessionFactory at the time of context loading.
When you need an session from sessionFactory you will just call:
Session session = HibernateHelper.getSession();
//work with session
session.flush();
session.clear();
buildSessionFactory(); is deprecated in Hibernate 4 now we have to use buildSessionFactory(ServiceRegistry serviceRegistry) you can find new method in HibernateHelper.

I had a Db call on start up to get and cache the data and I'm getting to following. I have tried increasing the memory size on on my machine, no luck. Ive been reading about how this is a memory issue here: Hibernate "APPARENT DEADLOCK!!! Creating emergency threads for unassigned pending tasks!".
Here are me connection configurations:

Attempts to acquire new Connections from the database are hanging -- neither succeeding nor failing with an exception for an extended period of time. In the thread dumps, we can see that attempts to get new Connections are blocking on socket read. That is what you want to debug: why is that happening?
One possibility, as Nigel Savage suggests, is that you've hit some resource limit on the server side, perhaps a number of Connections beyond which the server blocks and waits for Connections to be returned before completing new Connections. If this is the case, changing the configuration and maybe capacity on the server side would resolve the issue. An easy way to test this hypothesis would be to choose a much lower pool size (a maxPoolSize you are sure the server can easily handle) and see if the APPARENT DEADLOCK continues to manifest. If it goes away, probably server side Connection capacity is the culprit.
You could workaround this issue with maxAdministrativeTaskTime. But I would not recommend that. It's best to understand and fix the problem than to kludgily force it to go away.
For instance, I have the following entity:
#Entity
public class MyClass {
#Id
#GeneratedValue
private Integer Id;
private String value;
private boolean check = false; // <-- HERE!
// getters & setters
}
If I decide to change the check property's name to validate:
#Entity
public class MyClass {
#Id
#GeneratedValue
private Integer Id;
private String value;
private boolean validate = false; // <-- HERE!
// getters & setters
}
I had configured a hsqldb with:

As the hibernate.hbm2ddl.auto is set to update shouldn't it update the schema if I make any change at the code?
I got this error trying to access validate because the schema wasn't updated:

UPDATED:
after turn on the sql log I see this:
ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate (SchemaUpdate.java:261) main :HHH000388: Unsuccessful: alter table PUBLIC.my_class add column validate boolean not null
ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate (SchemaUpdate.java:262) main :default expression needed in statement [alter table PUBLIC.my_class add column validate boolean not null]
I don't know why is not adding the default false to the statement. In addition it's trying to add a new column instead of update it
because boolean can't be null, I notice that initialize at the object the validate=false doesn't have any effect. So I force to do it in JPA with:
#Column(columnDefinition = "boolean default false")
private boolean validate = false;
This error represents you don't have enough privileges on the schema you are currently working on.
Check the below line.
Caused by: org.hsqldb.HsqlException: user lacks privilege or object not found: MYCLAS0_.VERIFY
Validate if you have update schema permission on this said schema. Use this link thi understand more about this.
I'm practicing on hibernate. I'm trying to connect local mysql server and get some information but have some error messages on my console. I debugged my code and found the initial part when I'm trying to create a session factory
Configuration configuration = new Configuration();
this part of my code to cause an java.lang.NullPointerException error. I'm pretty sure I have import the all hibernate jars.
hibernate.cfg.xml:
<?xml version='1.0' encoding='UTF-8'?>

this is where I'm trying to build sessionfactory:
public static SessionFactory createSessionFactory() {
Configuration configuration = new Configuration();
configuration.configure();
//Configuration configuration = new Configuration().configure(new File("C:\\Users\\user\\workspace\\Hotel\\src\\hibernate.cfg.xml"));
serviceRegistry = new ServiceRegistryBuilder().applySettings(
configuration.getProperties()).build();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
return sessionFactory;
}
Console:

Any idea what is wrong with my connection?
UPDATE
I am running my connection from:
java -cp C:/user/hsqldb-2.3.2/hsqldb-2.3.2/hsqldb/lib/hsqldb.jar org.hsqldb.server.Server –database.0 file:testDB –dbname.0 testDB
UPDATE
I started my server with:
java -cp C:/user/hsqldb-2.3.2/hsqldb-2.3.2/hsqldb/lib/hsqldb.jar org.hsqldb.server.Server --database.0 file:testDB --dbname.0 testDB
However, I get this long exception(the error starts much earlier, because of that I am posting all of it):

UPDATE
after removing a space it seems ot work now!
According to this part of the documentation you should be starting the database like this:
java -cp C:/user/hsqldb-2.3.2/hsqldb-2.3.2/hsqldb/lib/hsqldb.jar org.hsqldb.server.Server –-database.0 file:testDB –-dbname.0 testDB
Note the use of -- instead of -
I ran into this as well as this problem:
https://stackoverflow.com/a/52031333/6710870
When I didn't know that the config file way of setting --dbname or -dbname is server.dbname.#=YOURDB
I am trying to run hibernate in a Java project that is referenced by a web project. Simple enough except that I can't get hibernate to connect to my database. I have a lot of people describing this problem and getting tons of answers however none seem to work for me.
This is how my hibernate.cfg.xml looks like:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<mapping resource="com/amakena/profile/mapping/Gender.hbm.xml"/>
</session-factory>
</hibernate-configuration>
I debugged the code to DriverManagerConnectionProvider class, the exception is thrown attempting the getConnection() method
Connection conn = DriverManager.getConnection(url, connectionProps);
I checked the url and connectionProps and they are the ones in hibernate.cfg.xml
I have added mysql-connector-java-3.1.14-bin in my tomcat \lib folder and I can see it in eclipse under Libraries>Apache Tomcat v6.0>. I also added it to my %Javahome%\lib\ext and my CLASSPATH variable (which I know is useless by I am kindda desperate).
I made sure my driver is installed properly by running the following code just before the session.beginTransaction() which in turn leads to DriverManagerConnectionProvider.getConnection()
Class.forName("com.mysql.jdbc.Driver");
Properties connectionProperties = new Properties();
connectionProperties.put("user", "root");
connectionProperties.put("password", "root");
DriverManager.getConnection("jdbc:mysql://localhost:3306/dbname", connectionProperties);
I noticed that emitting the first line causes the same exception.

WARNING: --Erroring: batchId[24] message[org.hibernate.exception.JDBCConnectionException: Cannot open connection]
I appreciate all the help I could get. Thanks in advance.
Versions Used: Tomcat v6.0 - Hibernate 3.6.6 - Java 6 - Eclipse 3.5.2 R35x
You forgot the colon after "mysql":
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/dbname</property>
Here's the doc for the URL format:
jdbc:mysql://[host][,failoverhost...][:port]/[database]
No suitable driver always means that the driver JAR was loaded, but your URL syntax is incorrect.
jdbc:mysql://localhost:3306/dbname
You are missing the : after mysql
Another reason is that the driver class is not found, make sure your driver class is successfully loaded.
