Libraries needed for client-server execution, also for Hibernate tool execution
Libraries needed for web app execution are in WebContent/WEB-INF/lib
Most but not all libraries are in both places.
Here:
Most come from the Hibernate "core" distribution, v. 3.5.2.ga, from www.hibernate.org,
  that is, hibernate3.jar itself and the other libraries it needs, its "dependencies", 
  all available together in this distro. This is a subset of the included jars.
Others:
hibernate-tools.jar, freemarker.jar, jtidy-*.jar: from the Hibernate Tools distribution 
    v. 3.2.0.beta11 from www.hibernate.org
hsqldb.jar: from hsqldb.com, the database-in-memory, a great help in testing
Note that standard.jar and jstl.jar are not here, since they are needed only for JSP pages
at execution time.
