replacing the jars which are same with my library and 4.1.6. In both

Programming Languages

I am trying to develop a web project using Hibernate 4 and spring
3.1. I declared sessionFactory bean in the
applicationContenxt.xml.


<bean id="sessionFactory"
scope="singleton"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> /> <property name="configLocation"
value="classpath:hibernate.cfg.xml" />
</bean> />

I want to use Oracle database so my
hibernate.cfg.xml file is :


<session-factory> /> <!-- Database connection settings -->

<property
name="connection.driver_class">oracle.jdbc.driver.OracleDriver

Actually I'm using hibernate-annotations 3.3.1.GA (hibernate
3.2.6.ga) and hibernate-validator 3.0.0.ga but, due to validation
problems, I need to upgrade the libraries to hibernate-annotations
3.4.0.GA (hibernate 3.3.2.GA) and hibernate-validator 3.1.0.GA.

When I update my pom.xml file I get a lot of compilation errors.
I think there are hibernate packages that have been reallocated in the
new version, so I guess I must to add new dependencies. But I am not
able to know which.


Examples of packages and classes not
founded with the new version:


- package
net.sf.cglib.proxy

I want to provide a custom Batcher for Hibernate to use (for this
reason:
http://stackoverflow.com/questions/83093/hibernate-insert-batch-with-postgresql),
but I want to create a modification of whatever it's already using
(BatchingBatcher or NonBatchingBatcher). What's the default value of
hibernate.jdbc.factory_class, or how can I figure out which Batcher
Hibernate is currently using?

I have replaced the HQL queries with that of SQL to shift back to
plain JDBC from hibernate for many reasons. Now, I am not able to
understand what SessionFactory in hibernate means and what should I
replace it with in plain JDBC?Also, sessions in hibernate has a lot of
configuration stuff involved.How do I deal with all these in plain
JDBC?Please help.

I have an issue related to sequence not found when I upgrade
hibernate from 3.5 to 4.0.0.RC6:

Anyone know how to fix it? please let me know. I am using
Oracle10gDialect and override getNativeIdentifierGeneratorClass()
function by using my own SequenceGenerator. It has worked on Hibernate
3.5 but thrown exception when I upgrade to Hibernate 4.0.0.RC6



Below is my TableNameSequenceGenerator class:



public class TableNameSequenceGenerator extends
SequenceGenerator {

public void configure(Type type, Properties params, Dialect
dialect) throws MappingException {
if(params.getProperty(SEQUENCE) == null ||
params.getProperty(SEQUENCE).length() == 0) {
String tableName =
params.getProperty(PersistentIdentifierGenerator.TABLE);
if(tableName != null) {
String seqName = tableName + "_SEQ";
params.setProperty(SEQUENCE, seqName);
}
}
super.configure(type, params, dialect);
}
}


When I do debugging by using hibernate 4, tableName return REVINFO
only (it works in hibernate 3)



Thanks
