I have a JNDI created on my Weblogic Server 12c. I am trying to connect to the Oracle database on the server using datasource and create a table there using hibernate. But I keep getting same exception org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment] Part 1 Part 2. This exception comes after I submit id and name from index.jsp
Please see my java code and suggest any changes:

Let me know if you need more details or if question formatting needs improvement. Not an expert on Weblogic btw. Thanks.
Everything looks fine to me.
Try using ojdbc6.jar instead of ojdbc14.jar. As your Oracle is version 11 and java is 8. ojdbc14.jar is very old now.
Let me know if it works.

I've managed to change the Exeptions. With the help from #andrewJames I found out, that I have to use a dialect, which I didn't know. I also noticed that I am using old versions of Hibernate and co.
And sorry in advance, for every experienced coder how gets headaches from my stupidity. I am not new to coding, but I am very new to databases and dealing with dependency's outside from just API package things. I tried to google as much as I could find, and testing every thing I could. But I ended up having to ask again. I am very sorry.
Iive changed stuff around and now have this pom.xml:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>6.1.6.Final</version>
</dependency>
<dependency>
<groupId>org.xerial</groupId>
<artifactId>sqlite-jdbc</artifactId>
<version>3.40.0.0</version>
</dependency>
<dependency>
<groupId>com.github.gwenn</groupId>
<artifactId>sqlite-dialect</artifactId>
<version>0.1.2</version>
</dependency>
I've changed the dialect in the hibernate.cfg.xml:
<property name="hibernate.dialect">org.sqlite.hibernate.dialect.SQLiteDialect</property>
persistence.xml:
<property name="hibernate.dialect" value="org.sqlite.hibernate.dialect.SQLiteDialect" />
However, now I get the benefit of dealing with this exception:
[00:07:48] >> INFO << [org.hibernate.Version] - HHH000412: Hibernate ORM core version 6.1.6.Final

My database is on a Microsoft SQL Server 2017 instance that uses Windows Authentication. I have added both the MSSQL JDBC (v6.4.0) updated IntelliJ with the -Djava.library.path VM option so that sqljdbc_auth.dll (required for Windows Authentication) is accessible.
From what I can tell in my research into this ambiguous error message, it could have many different causes, but ultimately boils down to just not being able to connect to the database somehow. Most of the other Q&A I've found seems to be specific to other databases or SQL Server that doesn't use Windows Authentication.
I have copied the JDBC URL directly from my datasource config in IntelliJ so I know that it is correct and works properly in the IDE.
What else is required to properly configure Hibernate to connect to SQL Server?

If you are using spring then, Add autowire on sessionfactory or get it from application context. You can use following code
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
public class ApplicationContextProvider implements ApplicationContextAware{
private static ApplicationContext context;
public static ApplicationContext getApplicationContext() {
return context;
}
#Override
public void setApplicationContext(ApplicationContext ac)
throws BeansException {
context = ac;
}
}
You can use this class anywhere in your code like
ApplicationContextProvider.getApplicationContext().getBean("sessionFactory");
Please try the following code for creating sessionfactory
final StandardServiceRegistry registry = new StandardServiceRegistryBuilder().configure() // configures settings from hibernate.cfg.xml
.build();
try {
sessionFactory = new MetadataSources( registry).buildMetadata().buildSessionFactory();
}
catch (Exception e) {
StandardServiceRegistryBuilder.destroy( registry );
}
Hope this helps.
I have created a java application which will select ceratin values from the table and print it using hibernate.I have used HSQLDb as the back end.But after executing I am getting the error
user lacks privilege or object not found:
But iam getting the query when i execute for the first time as
Hibernate: select ifmain0_.IF_ID as IF1_0_, ifmain0_.IF_NAME as IF2_0_ from IF_MAIN ifmain0_
But after that i am getting the above error. So i deleted the sample.lck file and after executing two times again I am getting the same error
