SPRING: Requested bean is currently in creation: Is there an unresolvable circular reference

I'm trying to implement hikari but I have this error:
/META-INF/datasource.beans.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'dataSource': Requested bean is currently in creation: Is there an unresolvable circular reference?
My config:
<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
<property name="poolName" value="abc_connection_pool" />
<property name="dataSourceClassName" value="com.informix.jdbcx.IfxDataSource"/>

</bean>
Environment
HikariCP version: HikariCP-java6 2.3.13
JDK version : 1.6
Database : Informix
Driver version : Ibm.informix.jdbc 3.00.JC3
I change the previous pool that was running by Hikari and I get that error

The parent tag beans was configured default-autowire = "byName"
I detele it and solved the problem.

Hibernate BeanCreationException

I'm trying to use Hibernate in my Spring application but i've got an error on the project's deployment

I've many jars in my classpath and i thoutgh it doesn't miss anyone. Could you help me finding an issue ?
Thanks

You need to put the hibernate-annotations.jar on the classpath.

Cannot find class [org.hibernate.cfg.AnnotationConfiguration]
This is the reason, Can you check for this class in classpath.

org.hibernate.cfg.AnnotationConfiguration is deprecated,
and all its functionality has been moved to org.hibernate.cfg.Configuration.
change your code
<property name="configurationClass">
<value>org.hibernate.cfg.Configuration</value>
</property>

Why do you want hibernate to manage the pool? The way it is setup in the second case is the correct way to configure dataSource & hibernate session factory with spring. This will work correctly with spring transaction management.
When you pass the dataSource as a parameter to the sessionFactoryBean the hibernate properties related to the dataSource configuration will be ignored. If you insist upon hibernate managing the pool you can try by removing the dataSource property injection in the AnnotationSessionFactoryBean. The driverClass, jdbcURL etc needs to now be specified as a part of hibernate properties.
From the spring javadoc.
Set the DataSource to be used by the SessionFactory. If set, this will
override corresponding settings in Hibernate properties. If this is
set, the Hibernate settings should not define a connection provider to
avoid meaningless double configuration.
http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/orm/hibernate3/AbstractSessionFactoryBean.html#setDataSource(javax.sql.DataSource)
You can either let spring manage the connection pool (by way of configuring the datasource bean and passing it to sessionFactory) or let hibernate manage it completely. Half & half will not work.

Does the parameter type of the setter match the return type of the getter?

I am trying to learn how to use DAO and BO classes and I am getting the following error
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [spring/database/Hibernate.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'annotatedClasses' of bean class [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Bean property 'annotatedClasses' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

I dont know where the error is coming from as my getter and setter methods in my countries.java and customer.java classes are all correct!
Does anybody know whats going wrong? (if you need to see any of the other classes just add a comment saying which classes and il post them up)
Thanks

It's actually complaining about the annotatedClasses property of the session factory, you are using a LocalSessionFactoryBean that doesn't have it (you have commented out AnnotationSessionFactoryBean that does have it).

Looks like you want to set "annotatedClasses" property originally coming from AnnotationSessionFactoryBean while you are actually using LocalSessionFactoryBean that does not have this property.

Hibernate + Spring - xml mapping not found

I have simple application with following folder structure:
ProjFolder
|-----src
|----------packagename
|---------------{sourcefiles}
|----------META-INF
|---------------{beans.xml}
|---------------{hibernate.cfg.xml}

here is the part of beans.xml Spring config file:

when i start my unit tests i getting following exception:

The same exception is thrown when i type
<property name="mappingResources">

</list>
</property>
Why spring cant find this file and how i must fill its location to make this code work?
Thanks in advance.

Have you tried removing the classpath: prefix? In looking at the Hibernate code, the mappingResources setter expects passes the strings to new ClassPathResource(String). This expects classpath resources already. The string then gets passed to ClassLoader.getResourceAsStream(String). None of this code would strip the "classpath:" prefix from the front of the resource string.

I'm not sure the error message is consistent with the beans.xml content you posted.
In the error you have
[classpath:/META-INF/EntityMapping.hbm.xml]
which isn't the same as
classpath:./META-INF/EntityMapping.hbm.xml
Notice the missing "." at the beginning in the error.
The second beans.xml configuration, should probably produce a different error message with:
[classpath:EntityMapping.hbm.xml]
This would be searching for the file in the root of your compiled application (jar, war, exploded, what have you).
