I have the following method in my main application class:

118: public void testHibernate()
119: {
120: Configuration cfg = new Configuration();
121: cfg.addResource("golfbase/Courses");
122: cfg.setProperties(System.getProperties());
123: SessionFactory sf = cfg.buildSessionFactory();
124: Session session = sf.openSession();
125: session.close();
126: }

It keeps throwing the following exception on the very first line:

Exception in thread "main" java.lang.NoClassDefFoundError: org/dom4j/DocumentException
at golfbase.golfBase.testHibernate(golfBase.java:120)
at golfbase.golfBase.<init>(golfBase.java:51)
at golfbase.golfBase.main(golfBase.java:66)


I have followed all the information in Hibernate In Action and the sample code from the Hibernate 3.1 installation runs fine (build eg) so I know I have installed properly. I am using Eclipse and have added the hibernate3.jar, log4j-1.2.11.jar, and mysql-connector-java-3.1.12-bin.jar files to my project. My hibernate.cfg.xml file is as follows:

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

</session-factory>

</hibernate-configuration>

Pretty basic, but it doesn't work. Any ideas? Thanks.

Ok, have some patience I'm new at this. Found I was missing lots of other jars (dom4j, commons-logging, commons-collections, cglib, asm). Added them and got a bit farther. Now I am getting the following when it tries to build a SessionFactory:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/transaction/Synchronization
at org.hibernate.impl.SessionFactoryImpl.buildCurrentSessionContext(SessionFactoryImpl.java:946)
at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:311)
at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1176)
at golfbase.golfBase.testHibernate(golfBase.java:122)
at golfbase.golfBase.<init>(golfBase.java:51)
at golfbase.golfBase.main(golfBase.java:66)

Looks like I'm missing some kind of java extension? I'm not using J2EE, just J2SE. Is that the problem?

Hi,

Looks like you don't have another jar in the classpath.

jta.jar

Add this and test it.

Note:javax/transaction/Synchronization is also available in the j2ee.jar, but there are few conflicts.

All the Best
