Hibernate saveOrUpdate Not working with Dynamic mapping

I am using Hibernate dynamic modeling for persisting my objects. The issue i am facing right now is it is throwing exception when i am calling saveOrUpdate function. The exception is
2020-07-08 23:14:06 WARN SqlExceptionHelper:137 - SQL Error: 1062, SQLState: 23000
2020-07-08 23:14:06 ERROR SqlExceptionHelper:142 - Duplicate entry 'TYUTQ-2020-07-08 20:19:53' for key 'PRIMARY'
2020-07-08 23:14:06 ERROR ExceptionMapperStandardImpl:39 - HHH000346: Error during managed flush [org.hibernate.exception.ConstraintViolationException: could not execute statement]
When object is going to insert first time, it will successfully inserted but when object is already present in the database then saveOrUpdate method again call the insert method. I verified by using SHOW_SQL = "true" property.
The question is why it is not calling the update method?
Hibernate mapping file is :
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class entity-name="myTable">
<composite-id>
<key-property name="code" column="code" type="java.lang.String" />
<key-property name="datetime" column="datetime" type="java.sql.Timestamp" />
</composite-id>
<property name="A" column="A_colummn" type="java.math.BigDecimal" />
<property name="B" column="B_column" type="java.math.BigDecimal" />
<property name="C" column="C_column" type="java.math.BigDecimal" />
<property name="D" column="D_column" type="java.math.BigDecimal" />

<property name="F" column="F_column" type="int" />
<property name="G" column="G_column" type="java.sql.Timestamp" />
</class>
</hibernate-mapping>
And my code is
List<Map<String, Object>> toBeSaved = getTransformedObjects();// all objects belong to same table
Transaction tx = null;
try (SessionFactory factory = HibernateUtils.getSessionFactoryFromXml(profile, job.getXmlMapping());// Creating Session from XML in my utils class
Session session = factory.openSession()) {
tx = session.beginTransaction();
toBeSaved.forEach(map -> {
session.saveOrUpdate(job.getTableName(), map);
});
tx.commit();// Here exception occurs
} catch (HibernateException e) {
rollbackTransactionAndPrintException(e, destTx);
}
Currently there is only one record in map and content of map is :
{
datetime=2020-07-08 20:19:53.21,
F_column=1,
A_colummn=0.421,
G_column=2020-06-16 17:21:05.0,
code=TYUTQ,
B_column=0.000,
C_column=0.000,
D_column=50.540
}
i am using hibernate version 5.3.5.Final and i am badly stuck in it.
Can anyone tell me how to resolve this ? Thanks in advance.

iBatis Error parsing XPath '/sqlMapConfig/sqlMap'

i'm new to ibatis. i like to split the SQLMapConfig file and SQL map resources into 2 file. but when i run the project its seems to show an error.
so below are my 2 file SQL Map.
SQLMapConfig.xml :
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMapConfig PUBLIC "-//iBATIS.com//DTD SQL Map Config
2.0//EN" "http://www.ibatis.com/dtd/sql-map-config-2.dtd">

<property name="JDBC.Username" value="root"/>
<property name="JDBC.Password" value=""/>
</dataSource>
</transactionManager>
<sqlMap resource="configuration/db/tbluser.xml" />
</sqlMapConfig>
and here is the SQL Map resources tbluser.xml :
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN" "http://www.ibatis.com/dtd/sql-map-2.dtd">

SELECT user_id AS sUserId FROM users where user.id = #sUserId#
</select>
</sqlMap>
but after i run the project i've got this error :

can anyone help me? thanks.

Could not find resource configuration/db/tbluser.xml, so try add prefix classpath:
<mapper resource="classpath:configuration/db/tbluster.xml">

try use
<typeAlias alias="classMUser" type="com.me.bean.MUser" />
<resultMap id="userMap" class="classMUser">
<result property="sUserId" column="sUserId" />
</resultMap>
<select id="getUserById" parameterClass = "com.me.bean.MUser" resultMap="userMap">
SELECT user_id AS sUserId FROM users where user.id = #sUserId#
</select>

In my case, the issue was:
<select id="someId" parameterClass="hashmap"
resultClass="someResultClass" resultMap="someResultMap">
I have written "hashmap" in resultMap instead of "someResultMap".
Correcting this solved the compilation issue.

Insert Stored Procedure mapped with Hibernate

I'm trying based on some examples and Hibernate documentation for mapping a Stored Procedure, I just need to insert some data wich is not for a single table, but I got the message:
Could not parse mapping document from resource
The mapping file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="Data">
<id column="col_id" name="dataId">
<generator class="assigned" />
</id>
<property column="col_liq" name="dataLiq" />
<property column="col_td" name="dataTd" />
<property column="col_numdcto" name="dataNumDoc" />
<sql-insert callable="true" check="none">
{call sp_update_data(?,?,?,?)}
</sql-insert>
</class>
</hibernate-mapping>
The "Data" object is just a POJO.
I will appreciate any idea or sugestion.

just to let others to know how it works due finally I did it.
The mapping is correct with just one point, Hibernate will set the Id as the last field, so the procedure should get it in that position, at least that you do some "trick".
In Java when calling the procedure is like a normal save, the rest is like working with a normal entity.

any help would be appreciated.

this is the basic steps that need to be followed while developing hibernate application ( am telling you from the basic level)
Steps To Create Hibernate Prog
Create Project
Create package inside the project (This is what I think You have missed (it is mandatory) - Ex: package in.myproject.test)
Create POJO Classes, configuration and hbm files
And at last, write your Java application
Remember
Creating package is must
cfg.configure("hibernate.cfg.xml"); -- we supply configure method, the configuration file name when we give our own name to the configuration file ( Ex - "myConfiguration.cfg.xml" (or) "myConfig.xml" etc).
Even if you supply the default configuration file name i.e "hibernate.cfg.xml", still it is fine (but not recomended)

simply there was error in this
<mapping resource="/login.hbm.xml"></mapping>
i just converted it to this
<mapping resource="login.hbm.xml"></mapping>
and it worked,besides this there were minor errors in field name property of login.hbm.xml which i sorted out by simply changing the names as they were on mysql table name.

What can I do with "Could not parse configuration" error from Hibernate?

I am following Java Hibernate tutorial example from YouTube. Everything looks great until I try to run code which is supposed to create table Employee on Apache Derby server. I tried to use SQL server (2008) first and I was getting the same error.
Could not parse configuration: hibernate.cfg.xml and there is also timeout error. I appreciate any help. Thanks.
Here is the error I get:

AnnotationConfiguration config = new AnnotationConfiguration();
config.addAnnotatedClass(Employee.class);
config.configure("hibernate.cfg.xml");
new SchemaExport(config).create(true, true);
}
}
What did I do wrong?

This means the hibernate.dtd cannot be resolved - its resolution is attempted on the server. The dtd is contained in the jars files - see here and here for how to resolve it.
