Galera, tenho uma classe chamada empresa que é cacheada.

@Entity @Table(name = "empresa") @org.hibernate.annotations.Cache(usage=org.hibernate.annotations.CacheConcurrencyStrategy.READ_WRITE) @NamedQueries( {

Estou usando o EhCache como fornecedor de cache.

Estou usando a propriedade

que desabilita o mapeamentos do cache, deste modo, todo o cache é desabilitado da aplicação,
(ao contrário seria necessário eu passar em todos os arquivos e retirar os mapeamentos de cahce)
mas quando rodar a aplicação, aparece este erro.

Coloca aqui o teu xml de configuração do Hibernate. Tem algum problema nesse aquivo.

Galera, acho que descobri o erro, eu mudei a parte onde defino os caches e coloquei no início do arquivo xml do hibernate, fiz dois testes, aqui um em cima e outro embaixo, realmente aquele que está em cima funciona,

Funcionou desta maneira

&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
&lt;!DOCTYPE hibernate-configuration PUBLIC

        &lt;property name="hibernate.cache.use_second_level_cache"&gt;true&lt;/property&gt;   
        &lt;property name="hibernate.cache.provider_class"&gt; org.hibernate.cache.EhCacheProvider &lt;/property&gt;
     
        
        &lt;!-- properties --&gt;
        &lt;property name="connection.driver_class"&gt;       com.mysql.jdbc.Driver   &lt;/property&gt;

        &lt;property name="show_sql"&gt;true&lt;/property&gt;
        &lt;property name="connection.username"&gt;root&lt;/property&gt;
        &lt;property name="connection.password"&gt;root&lt;/property&gt;
        &lt;property name="connection.pool_size"&gt;10&lt;/property&gt;
