Invocation of init method failed – hibernate exception of caching

Invocation of init method failed – hibernate exception of caching

While working with hibernate you might come up with this error, as I do :(
Fortunately, here is how to make your java happy:

On your hibernate.xml [ or maybe you might named it other ], there is a part describing property:

<property name="hibernateProperties">
 <props>
 <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
 <prop key="hibernate.show_sql">true</prop>
 <prop key="hibernate.c3p0.minPoolSize">5</prop>
 <prop key="hibernate.c3p0.maxPoolSize">200</prop>
 <prop key="hibernate.c3p0.timeout">1800</prop>
 <prop key="hibernate.c3p0.max_statement">50</prop>
 <prop key="hibernate.generate_statistics">true</prop>
 <prop key="hibernate.cache.use_second_level_cache">true</prop>
 <prop key="hibernate.cache.use_query_cache">true</prop>
 <prop key="hibernate.cache.provider_class" >org.hibernate.cache.EhCacheProvider</prop>
 </props>
 </property>

The last two props are the ones we want to blame!!
One way to get rid of this problem would be by just making the values of those to false – hmm… would work but we would miss the capability of caching … Here is the next

Download the ehcache from this location and put it in your classpath.
Update the hibernate.xml file’s property section by adding the following:

<prop key="hibernate.cache.provider_class" >org.hibernate.cache.EhCacheProvider</prop>

Now you+java+hibernate+me HAPPY..
hope would help someone..
