I am trying to use hibernate in my project.At run-time I get the follwoing error. I am using hibernate-2.1 with oracle 8i and have hibernate.jar in my classpath. On unjarring hibernate.jar I dont see the "path" net/sf/cglib/core/KeyFactory existing.Am I missing some thing over here.


Exception in thread "main" java.lang.NoClassDefFoundError: net/sf/cglib/core/KeyFactory
at net.sf.hibernate.impl.SessionFactoryImpl.<clinit>(SessionFactoryImpl.java:235)
at net.sf.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:750)
at eas.hibernate.TestController.poller(TestController.java:45)
at eas.hibernate.TestController.runController(TestController.java:35)
at eas.hibernate.TestController.main(TestController.java:24)


My mapping file is

hibernate.dialect net.sf.hibernate.dialect.OracleDialect
hibernate.connection.driver_class oracle.jdbc.driver.OracleDriver
hibernate.connection.username easusr01_dv
hibernate.connection.password easusr01_dv
hibernate.connection.url jdbc:oracle:oci8:@DEV

my code looks as follows :

sf = new Configuration()
.addClass(eas.hibernate.EasTlKeyvaluelookup.class)
.buildSessionFactory();

session = sf.openSession();

// read next polling period from database
List myList = session.createQuery(
"from EasTlKeyvaluelookup as lookup where lookup.keyidentifier = 'EASDaemonPollInterval'"
).list();

EasTlKeyvaluelookup temp = (EasTlKeyvaluelookup) myList.get(0);
pollInterval = Integer.parseInt(temp.getDefaultvalue());

NoClassDefFoundError: net/sf/cglib/core/KeyFactory
--> you need to put cglibxx.jar on your classpath (/lib for a webapp fot example)

you may need others jar like ehcache, c3p0 (if you use it) ....

Look at readme.txt file under lib directory of hibernate distribution. It will tell you which jar files should be in your classpath.
