I created a dynamic web project named HibernateSetUpTest2, jpa is marked as one of the project facets. I want to put this on a tomcat server in the future but right now I simply need to test if hibernate is working and it isn't.
I followed the MySQL DBCP Example on here (except for the jsp part):
https://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html
Now my xmls look like this:

In the project explorer of eclipse it shows a separate folder named Servers and in it is the context.xml :
<?xml version="1.0" encoding="UTF-8"?>

<WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>

url="jdbc:mysql://localhost:3306/javatest"/>
</Context>
In my src folder I wrote a Test:
package tests;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.EntityTransaction;
import javax.persistence.Persistence;
import entities.TestDataRow;
public class Hibernate {
public static void main(String[] args) {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("unitName");
EntityManager em = emf.createEntityManager();
EntityTransaction tx = em.getTransaction();
tx.begin();
TestDataRow t = em.find(TestDataRow.class, 1);
System.out.println(t.getFoo());
tx.commit();
em.close();
emf.close();
}
}
This uses the entity:
package entities;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name="testdata")
public class TestDataRow {
#Id
private int id;
private String foo;
private int bar;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFoo() {
return foo;
}
public void setFoo(String foo) {
this.foo = foo;
}
public int getBar() {
return bar;
}
public void setBar(int bar) {
this.bar = bar;
}
}
When I run the test as a java application it throws errors:

What am I doing wrong?
Your code itself looks fine (can't tell for sure but nothing seems to be seriously wrong) but you have a huge issue with your test itself:
It is a standalone test.
What the errormessage is telling you:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property
Basically means, that while attempting to lookup the JNDI variable (your DB resource definition) it had nowhere to "look". There is no context in your test. That is why it failed.
The standard ways of dealing with this kind of problem are:
either programmatically creating a context
or - just for the sake of the test - inserting a DB resource definition via simple autowiring, and not using JNDI at all.
Example and source for further ideas can be found here:
Setting up JNDI Datasource for uni testing
I think you need some initialisation or its a lack of configuration

Upgrade the java connector version with 5.1.46 minimum or above till latest 8.0.11 as old versions have issues with MySQL 8.
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.46</version>
</dependency>
EDIT: A solution to this problem has been found, the issue was that in
persistence.xml, the data-source-name needed to be prefixed with
java:comp/env/ like so: java:comp/env/jdbc/TSDB
I know this is a well documented issue, however, after many different attempts and ample reading, i still cannot configure a datasource to be used by Hibernate.
I am trying to develop a Tomcat application server which uses hibernate to connect to a MySQL server.
I am using Eclipse Version: 2018-12 (4.10.0)
Hibernate: 5.4.1.Final
Mysql connector: 8.0.14
SERVER: Apache Tomcat/9.0.14
The datasource is defined in server.xml:
<GlobalNamingResources>
<Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxTotal="100"
maxIdle="30" maxWaitMillis="10000" minIdle="5" name="jdbc/TSDB" password="PASSWORD"
type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/tstest?allowPublicKeyRetrieval=true" username="USERNAME"/>
</GlobalNamingResources>
Web.xml:
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" id="WebApp_ID" version="4.0">

<res-ref-name>jdbc/TSDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>
Context.xml:
<Context>
<ResourceLink name="jdbc/TSDB" global="jdbc/TSDB" type="javax.sql.DataSource" />
</Context>
Persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"
xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

<!-- EO Entity Classes Mappings -->
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>

</persistence>
Then when i try to create an entity manager in a web listener:
#WebListener
public class HibernateSessionFactoryListener implements ServletContextListener {
public final Logger logger = LogManager.getLogger(HibernateSessionFactoryListener.class);
public void contextInitialized(ServletContextEvent servletContextEvent) {
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("TsPersistence");
servletContextEvent.getServletContext().setAttribute("EntityManagerFactory", entityManagerFactory);
logger.info("Entity Manager Configured Successfully!");
}
I am getting the following error:

Is there any additional configuration i need to create?
Any help would be appreciated, thanks!
The GlobalNamingResource element declared in the server.xml file is equivalent (Docs) to the resource-ref declared in the web.xml file. I'd say remove the one inside web.xml
<resource-ref>
<res-ref-name>jdbc/TSDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
Hibernate fails to create new table new table for Entity in MySQL eventhough property "hibernate.hbm2ddl.auto" is set to "create-drop". It also fails with "create" and "update" with the same error: org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL via JDBC Statement.
Note: Database "test" is already created and empty.
If a table named "Test" is already created (even if its empty) everything runs perfectly and table is updated.
But after hours of Stackoverflowing and Googling I am giving up. I will create empty tables previously. If someone could find a better solution would be great.
Thanks,
Runing on Ubuntu 16.04.1 64 bits with Oracle Java 1.8.0_101. MySQL Server is 5.7.15. IDE used Eclipse Neon.

The cause of exception is an incorrect hibernate.cfg.xml file.
Please, use this structure
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
...
<mapping class="org.hibernate.hemant.dto.UDestails" />
</session-factory>
</hibernate-configuration>
You incorrect specify a persistent class in hibernate.cfg.xml. You use a mapping with annotations so you need to map a class not a resource
<mapping class="org.hibernate.hemant.dto.UDestails" />
Please, don't forget to close a session and sessionFactory.
I'm trying to run my simple program, i added spring framework jar files and common-logging jar files too into my reference library.
Here is my first program says HelloWorld.java:
package com.rajendra.lesson01;
public class HelloWorld {
private String message;
public void setMessage(String message){
this.message=message;
}
public void getMessage(){
System.out.println("Messge: "+message);
}
}
Here is my another program says MainProgram.java:
package com.rajendra.lesson01;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class MainProgram {
public static void main(String[] args){
ApplicationContext ac=new ClassPathXmlApplicationContext("bean.xml");
HelloWorld hw=(HelloWorld) ac.getBean("helloWorld");
hw.getMessage();
}
}
and here is my last one bean.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="helloWorld" class="com.rajendra.lesson01.HelloWorld">
<property name="message" value="My name is foo.." />
</bean>
</beans>
Everything goes fine according to tutorial but my Output says:

What's happening here please help? and also tell me how do you guys find the errors?
Help Would be appreciated!
http://www.tutorialspoint.com/spring/spring_hello_world_example.htm
In this example you have to put bean.xml out of the "com.rajendra.lesson01" package ... put it in resource package.
I hope this can help you.
