I am new to Hibernate. Was following a tutorial. Got this error. Can anybody help me with this??

you need to add:
<?xml version="1.0" encoding="utf-8"?>
at the beginning of your xml file.
Edit:(after you updated your code)
check if there are some blank space or other content before the <?xml ?>
check if there is a Byte Order Mark (BOM) before the <?xml ?> (here is a tutorial to remove it)
check if there is another <?xml ?> definition in your document

if any one get this The processing instruction target matching "[xX][mM][lL]" is not allowed. error
Solution to this error is that
1.This line should be the firs line and should not leave any space before this line.

How to use SSL encryption when connecting Vaadin App with Hibernate to MariaDB on Azure

I am currently working on a Java 8 app with Vaadin and Hibernate which I am trying to migrate to Azure for testing purposes.
Everything worked out so far except for one thing:
When I activate the require SSL option in The MariaDB on Azure, I can't connect anymore:
Caused by: java.sql.SQLException: SSL connection is required. Please specify SSL options and retry.
Unfortunately I didn't write this app myself and I am not too familiar with neither Vaadin nor Hibernate or even Java in general and how to establish ssl or db connections with those.So I need some help:
This is the JDBC Connection string in the Servlet.java file, where for my understanding the db init happens:
Connection con = DriverManager.getConnection("jdbc:mysql://<username>.mariadb.database.azure.com:3306/<db>?autoReconnect=true", "<username>", "<password>");
which I changed by just adding this to the URL: &useSSL=true&requireSSL=true&verifyServerCertificate=true
Now the app doesn't stop at the DB init anymore but still crashes before the page is fully rendered, with the same error message.
I found a hibernate.cfg.xml with the following content (I removed the mappings to keep it shorter):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>
<!-- Hikari -->

<property name="hibernate.hikari.dataSourceClassName">com.mysql.jdbc.jdbc2.optional.MysqlDataSource</property>

<property name="hibernate.hikari.dataSource.user">username</property>
<property name="hibernate.hikari.dataSource.password">password</property>
<property name="hibernate.hikari.dataSource.cachePrepStmts">true</property>
<property name="hibernate.hikari.dataSource.prepStmtCacheSize">250</property>
<property name="hibernate.hikari.dataSource.prepStmtCacheSqlLimit">2048</property>
<property name="hibernate.hikari.dataSource.useServerPrepStmts">true</property>
</session-factory>
</hibernate-configuration>
What do I have to change there to make use of SSL for the connection?
You may try:
<property name="hibernate.hikari.dataSource.url">jdbc:mysql://dbname.mariadb.database.azure.com:3306/db?useSSL=true</property>
Per my understanding, the properties in hibernate.cfg.xml will finally be used to generate a whole connection string. So, if there is no direct property for useSSL, you may add it to the url manually.

I'm getting XMLStreamException at [row,col]:[1,2]

I suddenly have started getting XMLStreamException in my project. Yesterday it worked just fine, today I made some minor changes and it's broken. I tried to rebase to previous versions, but nothing changed at all.

I began having the same issue. I hadn't updated anything, but restarting tomcat failed with lots of new exceptions. I noticed the below file was updated today and wondered if it was the source (it is referenced in each of my entity mappings):
http://hibernate.org/dtd/hibernate-mapping-3.0.dtd
So I updated my mappings to use the DTD from here:"hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" - and that works. So it does appear to be caused by the Hibernate's updated DTD file.
I guess your options are:
figure out what hibernate wants in the updated dtd
use the dtd from another source like sourceforge
use the dtd from your hibernate jar like this: "classpath://org/hibernate/hibernate-mapping-3.0.dtd"

What can be the error any help??
Try changing the DOCTYPE to this:
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<!DOCTYPE hibernate-configuration SYSTEM
"classpath://org/hibernate/hibernate-configuration-3.0.dtd">
This means that hibernate will load the DTD from classpath - it is usually included in hibernate jar in org/hibernate directory.
However, we use hibernate 3.5.6 - I don't hnow if this approach still works in the newer version - give it a try. The benefit of this is that you are completely independent on internet connection, proxies and so on.
Hibernate Configuration File Location
The first solution was to provide the DTD file location in the system using classpath. So the DocType that worked offline would be;
<!DOCTYPE hibernate-configuration SYSTEM
"classpath://org/hibernate/hibernate-configuration-3.0.dtd">
Use SourceForge DTD URL with SYSTEM
Another solution I found working is when I change the DTD URL to SourceForge and changed the declaration from PUBLIC to SYSTEM.
So below will also work if your system is offline.
<!DOCTYPE hibernate-configuration SYSTEM
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

MappingNotFoundException when running queries in IntelliJ Hibernate console

I'm trying to run HQL queries in IntelliJ's Hibernate Console. I've added the datasource to the Data Sources view and added my hibernate.cfg.xml to the Hibernate facet such that in appears in the Persistence view. The content of hibernate.cfg.xml is:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="connection.url">jdbc:mysql://localhost/mmanager</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.username">root</property>
<property name="connection.password">password</property>
<property name="dialect">com.puca.core.util.db.MySQLInnoDBDialect</property>
<!-- mapping files -->
<mapping resource="com/puca/messagemanager/api/model/XmlApiDlrMapping.hbm.xml"/>
</session-factory>
</hibernate-configuration>
The .hbm.xml is shown in green, whereas if I change it to a file that doesn't exist it is shown in red, so it seems that IntelliJ can find it. However, if I run a simple query in the console like:
from XmlApiDlrMapping xmlApiDlrMapping
where xmlApiDlrMapping.retries = 5
I get an error:
java.lang.RuntimeException: org.hibernate.MappingNotFoundException: resource: com/puca/messagemanager/api/model/XmlApiDlrMapping.hbm.xml not found

at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1508)
at org.hibernate.cfg.Configuration.configure(Configuration.java:1462)
I'm using IntelliJ 10.5.4.
It's exactly what it says in the error message. The mapping XML file is missing:
com/puca/messagemanager/api/model/XmlApiDlrMapping.hbm.xml
These files are used to map table columns to your entity class fields.

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:

Here is my hibernate.cfg.xml file:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

And, here is the code I am running:
package com.hibernate.chapter1;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
public class TestEmployee {
public static void main(String[] args) {
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.
