Bean CurrentlyInCreationException: Error creating bean with name : Requested bean is currently in creation: Is there an unresolvable circular reference?

This CurrentlyInCreationExceptionexception happens during the construction of the bean.

If the bean has reference to other beans, and if those beans which are referenced have the this bean as property or constructor parameter, then it would be cyclic and hence this exception would be thrown.

So, check if you have beans that are referring to each other on you hbm/annotations files.

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">
 <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>

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..
