As stated on the subject, my problem is the EntityManagerFactory cannot be built. I am using Maven + Hibernate. I am connecting to a MySQL DB (<jdbc://mysql://localhost:3306/<dbname>).
The weird thing here is during debugging in Eclipse, it is working fine. But when I build it using Maven build, the JAR file is throwing such error. I checked the Manifest file already and all the necessary JARs were included in the Class-Path. Below is the error of the JAR displayed in the console:

What am I doing wrong here? Or what am I lacking?
As mentioned, it's working on Debug. But when I package it into JAR,(with all the necessary JARs present in the libs folder), it's not.
add this in your xml file
<property name="javax.persistence.validation.mode">none</property>
<class>classname</class>
I suspect your entity is not named classname, so try specifying the full classpath-name (for example foo.bar.realclassname with realclassname being the name of your entity-class).
The persistence.xml file is supposed to go in the META-INF folder at the root of the jar. Check if it is there or not. I am guessing that this is purely a classpath related issue.
Try to rename your persistence unit. This is important, since the name is used to identify persistence unit related to each EntityManager.
So:
<persistence-unit name="<name>">
should be replaced with (for instance):
<persistence-unit name="myUnit">

What can I do with it? I tried many solutions but none of them work, hope anyone could help me because it makes me very frustraded..
I am trying to run the program given in hibernate tutorial(basic).But I am facing error. Surprisingly, there are very few error logs displayed in the console. If anyone can show me where I am going wrong, I will be grateful. I have spent lot of time trying to resolve it before posting it here.

Below are the jars I have added in the classpath
I
I have made some changes to the hibernate.cfg.xml and it started working.The modified xml is as below :
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="connection.url">jdbc:oracle:thin:#localhost:1521:XE</property>
<property name="connection.username">hr</property>
<property name="connection.password">hr</property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.Oracle10gDialect</property>
<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">create</property>
<mapping resource="org/hibernate/tutorial/hbm/Event.hbm.xml"/>
</session-factory>
</hibernate-configuration>
The change I done in this xml is modifying the connection url :
<property name="connection.url">jdbc:oracle:thin:#localhost:1521:XE</property>
Basically I would like to know why its trying to load the org.h2.Driver even though i'm not using it and consequently throwing the error as well.
And secondly why it's using the built-in connection pool when I've specified one.
Here's a snippet of my config file
<?xml version="1.0" encoding="utf-8"?>

The same url,user and password combination works when connecting via basic JDBC.
Anyone have suggestions?
That's an INFO message (nothing to worry about) because you set:
<property name="hibernate.temp.use_jdbc_metadata_defaults" value="false"/>
By default, if you don't specify this property, it will then be set to true, and a JDBC connection will be used to inspect the database metadata.
So you have two options:
You remove that property
You keep it, but you add this property as well:
hibernate.jdbc.lob.non_contextual_creation=true
but then you will get some other INFO message, telling that:
HHH000421: Disabling contextual LOB creation as hibernate.jdbc.lob.non_contextual_creation is true
It was a driver version problem for me,
-Make you have db2jcc4.jar and it is not conflicting with earlier version .
-Make sure you have specified currentschema
I have created basic hibernate application. It throw error message.
Error is:

Please tell me what is an issue in my code?
Thanks in advance..
In User.hbm.xml you have to use type="java.lang.String" (with a big 'S'). That's it.
AS I understand the problem in your code was caused by your User.hbm.xml mapping file. To be more precised by type="string" attribute of composite-id tab.
As I understand you don't need to put type attribute obligatory so try to skip it at all; hibernate should detect it automatically. I'm not sure in last sentece because I have not used composite keys, but there are a lot of examples where peoples don't define type explicitly.
Hmmm, in your mapping file you have
<key-property name="businessUnit" column="BusinessUnit" type="string"/>
<key-property name="userID" column="UserID" type="string"/>
That should be ...type="java.lang.String"... instead, but most likely you really don't need it - Hibernate will make a (usually very good) educated guess.
Cheers,
Hibernate use the reflection to determine the mapping type at runtime.
It seems your mapping is correct, But if you still getting the same problem.
I will suggest you to remove the type attribute for the time being test, from all the String type properties such as email,businessUnit,userId
try this way for all the String type properties
<property name="email">
<column name="Email"/>
</property>
or you can try with java.lang.String also
<property name="email" type="java.lang.String">
<column name="Email"/>
</property>
Both "string" and "java.lang.String" are aliases for org.hibernate.type.StringType, so either should work in terms of naming types.
I am actually not so sure the problem is in the mapping for User. That mapping looks fine. Based on that exception I would more expect that somewhere you have
<composite-id ... class="string">
or
<component ... class="string">
or something like that.
<composite-id name="userPK" >
<key-property name="businessUnit" column="BusinessUnit" type="String"/>
<key-property name="userID" column="UserID" type="String"/>
</composite-id>
try with changing string to String
