I have tried everything from java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES) & How to grant all privileges to root user in MySQL 8.0 Unable to find what I am doing wrong. Please suggest me anything which can work for me. You dont have to Grant Permissions to root it is already the Super User (Can do Issue with transaction/Hibernate persistence and MariaDB in Wildfly 15 Final. We are having issues after deploying our application in the latest Wildfly 15.0.0 Final recently released with the following exception: java.sql.SQLException: XAER_RMFAIL: The command cannot be executed when global transaction is in the IDLE state. In this short tutorial, we’ll look at the Spring JdbcTemplate “EmptyResultDataAccessException: Incorrect result size: expected 1, actual 0” exception. First, we’ll discuss in detail the root cause of this exception. Then, we’ll see how to reproduce it using a practical example, and finally learn how to fix it. 2. The Cause In the next example, an open connection to the SQL Server AdventureWorks2022 sample database is passed in to the function and a malformed SQL statement is constructed that doesn't have a FROM clause. Then, the statement is run and an SQL exception is processed. 1. Overview. There are many ways we can connect to a MySQL database from Java and in this tutorial, we’re going to explore several options to see how to achieve this. We’ll start by looking at arguably the most popular options using JDBC and Hibernate. Then, we’ll also look at some external libraries including MyBatis, Apache Cayenne and 3. The DriverManagerDataSource isn't meant to be used in production, in production you want to use a connection pool, the DriverManagerDataSource isn't a connection pool, I suggest using something like Tomcat JDBC or Commons DBCP as the connection pool. Your hibernate.c3p0 settings are useless, as you are configuring and injecting the 1 Answer. You are using ClientDriver to connect to a local database. The recent derby documentation (at the time of writing) says that. The class that loads Derby's local JDBC driver is the class org.apache.derby.jdbc.EmbeddedDriver. The class that loads Derby's network client driver is the class org.apache.derby.jdbc.ClientDriver. If so, the knowledge about Hibernate or any other database related tool has to remain inside the DAO, and Service should know nothing about it. If you, for example, decide to switch from Hibernate to, say, Jooq, or more generally speaking decide to change Relational Database for something else, maybe NoSQL, the service layer will remain just 7. After trying several approaches for a while I found two ways to get this working. Create a new EntityManager via EntityManagerFactory and use EntityManager.close () method. Just annotate the repository method with @Transactional annotation as suggested in @Procedure annotation orphaning database connections (spring-data-jpa).

I have already tried to change hibernate.hbm2dll.auto property in hibernate.cfg.xml file to create-drop and create. Spring JDBC Template provides a fluent API that improves code simplicity and readability and the JDBC Template is used to connect to the database and execute SQL Queries. JDBC (Java Database Connectivity) is an application programming interface (API) that defines how a client may access a database. It is a data access technology used for Java Symptoms.
