I'm using eclipseLink 2.5.2 in my project and sometimes I get the following exception:

I often read this site, but this is the first time I write, hope I won't make mistakes and apologize for my bad english.
I get to the point: I have to develop code to insert records on a single table of a postgresql db, using hibernate on a Springboot project. The table has got a sequence, and I would like to use it to get the id's value.
Into the hbm.xml file of my table I have this:
table="td_tito">
<id name="idTito" column="ID_TITO">
<generator class="sequence">
<param name="sequence">seq_td_tito</param>
</generator>
</id>
<property ..../>
<property ..../>
In the bean class I have the variable idTito and its getter and setter methods.
When i try to save by calling save method of my class that implements JpaRepository interface, I get the following exception:
12:56:06.746 [main] DEBUG org.hibernate.engine.transaction.internal.TransactionImpl - On TransactionImpl creation, JpaCompliance#isJpaTransactionComplianceEnabled == false

This is the Entity Class:

By removing the annotations I get this error as I try to start the Application:

Any suggestion? Thank you so much to everybody
Step
If you are using you must remove all annotations from the entity
This line is causing the search for hibernate_sequence:
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
Simply remove this line.
But I recommend to use use annotations. This will look like this:
#Id
#SequenceGenerator(name = "seq_td_tito", sequenceName = "seq_td_tito")
#GeneratedValue(generator = "seq_td_tito", strategy = GenerationType.SEQUENCE)
private Long idTito;
I struggled for sometime, then following combination worked, for the same strategy
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
my application.properties has these entries.
spring.datasource.username= postgres
spring.datasource.password= mypassword
spring.datasource.driver-class-name= org.postgresql.Driver
spring.jpa.generate-ddl= true
spring.jpa.hibernate.ddl-auto= update
spring.jpa.properties.hibernate.dialect= org.hibernate.dialect.PostgreSQLDialect
and pom.xml has one dependency as needed.
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<scope>runtime</scope>
</dependency>
please help me about Spring JPA Transaction Management
I have two methods: usersService.addUser and authoritiesService.addNew
#Service
#Transactional(propagation = PROPAGATION.SUPPORTS, readOnly=true)
public class UsersService {
#Autowired
UsersRepository usersRepository;
#Autowired
AuthotitiesRepository authoritiesReposotory;
#Transaction
public addUser(...){
usersRespository.addUser...
authoritiesRepository.addNew...
}
...
public interface UsersRepository extends JpaRepository<Users, String> {
#Transactional
#Modifying
#Query(value = "insert into users..."
}
public interface AuthoritiesRepository extends JpaRepository<Users, String> {
#Transactional
#Modifying
#Query(value = "insert into abc ...."
}
The problem is when authoritiesRepository.addNew throws Exception(by some SQL syntax) I want to automatically rollback user info.
How can I configure in repository, service ?

As #thanhngo alread mentioned. This is how to do it.
You already have the correct annotation on the addUser method and any RuntimeException will cause the transaction to be rolled back.
Make sure that usersRespository.addUser... and authoritiesReposotory.addNew... also have the #Transactional annotation

This table Kinokindergeldfall hat a foreign key in the table kinoantragsteller
#OneToOne (cascade = CascadeType.ALL , fetch= FetchType.EAGER)
private Kinokindergeldfall kinokindergeldfall;
et the class kinokindergeldfall:
#Column(nullable= false )
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "Kinokindergeldfall_Id_Seq_Gen")
private BigDecimal kindergeldfallid;
#Column(nullable = false)
private String kindergeldnummer;
#OneToOne(mappedBy = "kinokindergeldfall", cascade = CascadeType.ALL )
private Kinoantragsteller kinoantragstellerList;
If you don't supply #JoinColumn with a column name for some relation, JPA will assume the default one. The default one is constructed like <source_class_field_name>_<target_class_id_field_name> which in your case resolves to kinokindergeldfall_kindergeldfallid which is over 30 characters long. That's what causes the exception.
Since you wouldn't be able to create a column with this name in the first place, just add #JoinColumn(name = "<column name>") with the actual name of the column used as foreign key to another table (shorter than 30 characters).
#OneToOne (cascade = CascadeType.ALL , fetch= FetchType.EAGER)
#JoinColumn(name = "<column name>")
private Kinokindergeldfall kinokindergeldfall;
When trying to initialize hibernate from configuration file, I get NullPointerException ..
Root cause is shown as
Caused by: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: java.lang.NullPointerException (Caused by java.lang.NullPointerException) (Caused by org.apache.commons.logging.LogConfigurationException: java.lang.NullPointerException (Caused by java.lang.NullPointerException))
at org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryImpl.java:543)
I have all the logging related jars and properties files in class path.
My hibernate initialization code is :
private static final SessionFactory sessionFactory;
private static final ThreadLocal<Session> hibernateSession=new ThreadLocal<Session>();
static{
try{
sessionFactory=new Configuration().configure("llhs_hibernate.cfg.xml").buildSessionFactory();
System.out.println("done");
}catch (HibernateException he){
he.printStackTrace();
throw new ExceptionInInitializerError(he);
}catch (Exception e){
e.printStackTrace();
throw new ExceptionInInitializerError(e);
}
Simple java classes does not complain about log related error, for example following java class does not complain ..It properly initializes and writes to logs folder
public class MetadataService implements Serializable {
private static final Logger logger = LogManager.getLogger(MetadataService.class);
private static final long serialVersionUID = 1L;
public MetaData getMetaData(){
logger.info("Info");
try {
//some code here
} catch (Exception e1) {
logger.error("Error");
}
return metaData;
}
Since it works for stand alone Java class and not for class doing hibernate initialization --I am more perplexed ..Any pointer? Detailed trace
java.lang.ExceptionInInitializerError

There is alignment issue while posting trace, sorry abt that, not able to correct that one..
Finally, I was able to solve this. As later guessed it turned out to be an eclipse configuration. In eclipse 3.7, code name indigo, the way libs were being added to the classpath caused this issue ..
First way:
Debug Configurations->classpath->bootstarp entries, if Add libs added by selecting "Add Jars" options, THIS DOES NOT Work.
Correct WAY:
Define a classpath variable from window->preferences->java->buildpath->classpath variable, say HIBERNATE_LIBS and point it ti libs folder
Now, got to Debug Configurations->classpath->bootstarp entries, select "Advanced option" and add the class path variable. This FIXED the issue.
I guess this is specific to 3.7, as I upgraded the eclipse version and started getting this issue, First way still works in eclipse 3.2
I googled but can't find a solution for this. It is from Core JSF 3rd.
I did:
1) Included JSF Mojarra in Build path.
2) Included MySQL JDBC driver in Build path.
3) Copied MySQL JDBC driver to Tomcat "lib" folder and "ext" JDK folder.
4) I tested JDBC driver with a small Java app and it succeeded.
CustomerBean from corejsf source code:
public class CustomerBean {
#Resource(name="jdbc/corejsf")
private DataSource source;
public ResultSet getAll() throws SQLException {
Connection conn = source.getConnection();
try {
Statement stmt = conn.createStatement();
ResultSet result = stmt.executeQuery("SELECT * FROM Customers");
// return ResultSupport.toResult(result);
CachedRowSet crs = new com.sun.rowset.CachedRowSetImpl();
// or use an implementation from your database vendor
crs.populate(result);
return crs;
} finally {
conn.close();
}
}
}
Error:
SEVERE: Servlet.service() for servlet [Faces Servlet] in context with path [/DatabaseTest] threw exception [/index.jsp(12,3) '#{customer.all}' Error reading 'all' on type com.corejsf.CustomerBean] with root cause

You need to configure a JNDI datasource with the name jdbc/corejsf in Tomcat.
I suspect that datasource is not injected, since nothing in your class path interprets the #Resource annotation. As far as I know, #Resource is an EJB annotation, but Tomcat is no EJB container. Try looking up the datasource programatically.
