Hibernate + c3p0 Pool + ehcache fail start
Question
I have a JavaFX application which works fine until I add a 2º cache (ehcache with regions). After that, I start application but I get this error when try to create session factory:
08/10/2014 20:01:40 DEBUG Configuration:1841 - Preparing to build session factory with filters : {}
08/10/2014 20:01:40 INFO ConnectionProviderInitiator:190 - HHH000130: Instantiating explicit connection provider: org.hibernate.connection.C3P0ConnectionProvider
Exception in Application start method java.lang.reflect.InvocationTargetException
These are my files (I ommited private data):
hibernate.cfg:
<property name="javax.persistence.validation.mode">none</property>
<property name="connection.release_mode">auto</property>
<property name="current_session_context_class">thread</property>

hibernateUtil
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
public enum Util {
INSTANCE;
private final SessionFactory sessionFactory;
private Util() {
Configuration configuration;
StandardServiceRegistryBuilder builder;
configuration = new Configuration().configure();
builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
sessionFactory = configuration.buildSessionFactory(builder.build());
}
public static Util getInstance() {
return INSTANCE;
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
}
When I try to debug, stop at sessionFactory = configuration.buildSessionFactory(builder.build()); because session return is null. But if I remove pool, session works.
Also, on all *.hbm.xml files, I set cache by putting <cache usage="nonstrict-read-write" region="region1"/> . If I remove region, starts but I get an error because I don't defined a region and hibernate takes default name.

Finally, I fix the problem by myselft. Here are the answer:
hibernate.cfg
<!-- Pool -->
<property name="hibernate.c3p0.min_size">5</property>
<property name="hibernate.c3p0.max_size">20</property>
<property name="hibernate.c3p0.timeout">3000</property>
<property name="hibernate.c3p0.max_statements">50</property>
<property name="hibernate.c3p0.idle_test_period">300</property>
<property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
<!-- Cache -->
<property name="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</property>
<property name="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory</property>
<property name="hibernate.cache.use_second_level_cache">true</property>
<property name="hibernate.cache.use_query_cache">true</property>
<property name="net.sf.ehcache.configurationResourceName">/ehcache.xml</property>
NOTE: if you use a singleton in your sessionFactory class, then use SingletonEhCacheRegionFactory class, if not, then use org.hibernate.cache.ehcache.EhCacheRegionFactory .
Some latest dependencies version not work well with above configuracion, so I need to use previous in some cases.

And ehcache.xml with cache configuration:
<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="ehcache.xsd"
updateCheck="true" monitoring="autodetect"
dynamicConfig="true">
<diskStore path="java.io.tmpdir/ehcache" />
<defaultCache maxEntriesLocalHeap="10000" eternal="false"
timeToIdleSeconds="120" timeToLiveSeconds="120" diskSpoolBufferSizeMB="30"
maxEntriesLocalDisk="10000000" diskExpiryThreadIntervalSeconds="120"
memoryStoreEvictionPolicy="LRU" statistics="true">
<persistence strategy="localTempSwap" />
</defaultCache>
<cache name="org.hibernate.cache.internal.StandardQueryCache"
maxEntriesLocalHeap="5" eternal="false" timeToLiveSeconds="120">
<persistence strategy="localTempSwap" />
</cache>
<cache name="org.hibernate.cache.spi.UpdateTimestampsCache"
maxEntriesLocalHeap="5000" eternal="true">
<persistence strategy="localTempSwap" />
</cache>
</ehcache>
NOTE: This file works OK, but logs report warnings because I don't specified cache for current beans, so cache take default configuration. Also, I get some warning about mchange dependency file which mcach couldn't find but really it's not a error so don't worry about that kind of warns.
