The following are my codes. calling createSession() method in Main. I have two Entity classes.

Database connection is provided in my hibernate.cfg.xml

private static void createSession() {

        StandardServiceRegistry ssr = new StandardServiceRegistryBuilder().configure("hibernate.cfg.xml").build();
        Metadata meta = new MetadataSources(ssr).getMetadataBuilder().build();

        SessionFactory factory = meta.getSessionFactoryBuilder().build();
        Session session = factory.openSession();
        Transaction t = session.beginTransaction();

        SessionFactory fact = meta.getSessionFactoryBuilder().build();
        Session ss = factory.openSession();
        Transaction tt = session.beginTransaction();

        BatchJobConfig config = new BatchJobConfig();

        BatchJobConfigDetails details = new BatchJobConfigDetails();

        Timestamp timestamp = new Timestamp(System.currentTimeMillis());
        System.out.println("timestamp  ->  "+timestamp);

        BatchJobConfigDetails batchJobConfigDtl = new BatchJobConfigDetails(300, 3, "JAVA", date, "JAVA", date, "N",
                "Some Key", "Some value", "FT", "KEY DESCRIPTION", "Y");
        try {
            config.setBatchJobConfigDtl(batchJobConfigDtl);
            config.setAddUserCd("gdfdgdfgdgd");
            config.setBatchJobConfigId(505);
            config.setActiveInd("YYYY");
            config.setAddUserDtm(timestamp);
            config.setDeleteInd("N");
            config.setEndDtm(timestamp);
            config.setJobDesc("DESCRIPTION");
            config.setJobNm("JOB NAME");
            config.setJobType("Job Type");
            config.setLastUpdtDtm(timestamp);
            config.setLastUpdtUserCd("someone");
            config.setStatus("COMPLETED");
            config.setStartDtm(timestamp);
            ss.save(config);
            tt.commit();
            System.out.println("config session saved");

        } catch (HibernateException exception) {
            System.out.println("Problem creating session factory!!!!!!!!!!");
            exception.printStackTrace();
        } finally {
            fact.close();
            ss.close();
        }

        try {
            details.setAddUserCd("fffffffffffffffffffff");
            details.setAddUserDtm(timestamp);           
            details.setBusinessUpdtInd("dssssssss");
            details.setDeleteInd("NNNNNNNNN");
            details.setKeyDataType("ggggggggggggg");
            details.setKeyDesc("Description.......");
            details.setKeyNm("some key name");
            details.setKeyVal("someval");
            details.setLastUpdtDtm(timestamp);
            details.setLastUpdtUserCd("last user");
            BatchJobConfig batchJobConfig = new BatchJobConfig(1L, "JAVA", date, "C#", date, "N", "MissingCK",
                    "JOB DESCRIPTION", "FT", date, date, "COMPLETED", "Y");
            List<BatchJobConfig> b = null;
            b.add(batchJobConfig);
            details.setBatchJobConfigs(b);
            session.save(details);
            t.commit();
            System.out.println("details session saved");

        } catch (HibernateException exception) {
            System.out.println("Problem creating session factory....");
            exception.printStackTrace();
        } finally {
            factory.close();
            session.close();
        }

And created two of this tables in DB2 Database.

My project is spring-boot REST API GET all, GET 1 and PUT operations. Please take a look and let me know where I'm making mistake. Thank you in advance!!!!

Put all small letters "timestamp" instead of capital ones in your hbm.xml file. Something like:

<property name="addUserDtm" column="ADD_USER_DTM" type="timestamp" />
