dom4j-1.6.1
hibernate-commons-annotations-4.0.1.Final
hibernate-core-4.1.9.Final
hibernate-entitymanager-4.1.9.Final
hibernate-jpa-2.0-api-1.0.1.Final
javassist-3.17.1-GA
jboss-transaction-api_1.1_spec-1.0.0.Final
jboss-logging-3.1.0.GA

Answer 2

You can download jars related to hibernate at

http://sourceforge.net/projects/hibernate/files/hibernate3

unzip it and check whether the following files are added to your lib folder

Anttr-2.7.6.jar
asm.jar
asm-attrs.jar
cglib-2.1.3.jar
commons-collections-2.1.1.jar
commons-logging-1.0.4.jar
ehcash.jar
dom4j-1.6.1.jar
hibernate3.jar    <--Check this version of your jar
jta.jar
log4j-1.2.3.jar

To run hibernate related programming and among all the jars hibernate3.jar is the main file..

Along with the hibernate jars you must include one more jar file related to the type of database(mysql,oracle,etc..) you use..

Try using proper versions of jar before you execute your program...some versions of jars are not supported to run...and the latest one is recommended...

Answer 3

You haven't provided the package name in your HibernateUtil class. If no package is defined the class will belong to default package and you cannot get the HibernateUtil class from org.com.hibernate.HibernateUtil

Answer 4

If someone is facing the same problem who are using Glassfish server you have to do the following,

1. Go your Glassfish installation path and add your database's jdbc driver under the path glassfish/domains/domain1/lib/

2. Restart your Glassfish server.
