Estou tentando ativar o second level cache do hibernate, mas nao estou conseguindo, obtenho uma serio de erros muito estranha... sem o cache, tudo funciona normalmente, porem com o cache habilitado, tenho uma sequence grande de erros, aqui esta o meu hibernate.properties
# Configuracao do Hibernate para Conexao com base de dados
#Configuracao para PostGres
hibernate.dialect org.hibernate.dialect.PostgreSQLDialect
hibernate.connection.driver_class org.postgresql.Driver
hibernate.connection.url jdbc:postgresql://localhost:5432/infotx
hibernate.connection.username postgres
hibernate.connection.password wiling250589*#
hibernate.show_sql true
hibernate.format_sql true
transaction.factory_class org.hibernate.transaction.JDBCTransactionFactory
hibernate.cache.use_query_cache true
hibernate.cache.provider_class org.hibernate.cache.EhCacheProvider
#Aqui as Configuracoes do C3p0, um controlador de pools de conexao
hibernate.c3p0.min_size=5
hibernate.c3p0.max_size=20
hibernate.c3p0.timeout=1800
hibernate.c3p0.max_statements=50
estou usando hibernate 3.3.1 e hibernate annotations 3.4.0 o meu ehcache.xml esta no classpatch, tambem coloquei la o jar do ehcache, abaixo segue a lista de erros que estou tendo, se alguem puder me ajudar pessoal, ficarei muito grato! pois nao sei o que pode ser isso, inclusive ja tentei outros caches como oscache, mesma coisa…

Antecipadamente agradeço a boa vontade do pessoal! Abraço a todos
Bom dia Pessoal, obrigado pelas respostas, o jar do ehcache eu coloquei sim no classpath, tentei anotar as classes com a anotacao de cache tambem mas estranho que tenho o mesmo erro… sera que falta algum jar para que o ehcache possa funcionar? pois no hibernate so tem um jar do ehcache, valeu mesmo pelas respostas pessoal, agradeço muito mesmo, mas voces acham que poderia existir uma outra causa para este erro?
vou postar todo o stacktrace incluindo logs do hibernate quando estou inserindo a entidade no banco, e mais uma duvida, a anotacao @Cache, é realmente esta: import org.hibernate.annotations.Cache; ?

Será que o jar está sendo exportado para sua pasta web-inf/lib quando vc manda para o servidor??? Por ser que por alguma configuração o jar não foi parar lá…
Agradecido por todas as sujestoes! depois que eu fiz um exame para tentar encontrar a classe de cache e nao consegui, percebi que na verdade o nome do cache estava incorreto! talvez pela versao do ehcache, pois o nome do cache na verdade é
net.sf.ehcache.hibernate.EhCacheProvider
se alguem passar pela mesma situacao, ai vai uma dica! abraços pessoal!
