Override hybris commonI18NService roundCurrency method

Trying to override spring bean using Alias.
I want to over ride roundCurrency method of commonI18NService
OOTB definition
<alias alias="commonI18NService" name="defaultCommonI18NService"/>
<bean id="defaultCommonI18NService" class="de.hybris.platform.servicelayer.i18n.impl.DefaultCommonI18NService" parent="abstractBusinessService">
<property name="languageDao" ref="languageDao"/>
<property name="currencyDao" ref="currencyDao"/>
<property name="countryDao" ref="countryDao"/>
<property name="regionDao" ref="regionDao"/>
<property name="conversionStrategy" ref="conversionStrategy"/>
</bean>
Our custom code :-
public class DefaultCustomCommonI18NService extends DefaultCommonI18NService
{
#Override
public double roundCurrency(double value, int digits)
{
// custom logic
return value;
}
}
Inject custom bean :-
<alias alias="commonI18NService" name="defaultCustomCommonI18NService"/>
<bean id="defaultCustomCommonI18NService" class="com.extended.service.impl.DefaultCustomCommonI18NService" parent="defaultCommonI18NService"/>
But it throws exception on server startUP

This is happening because the autowiring strategy of defaultConverterRegistry is byType:
<bean id="defaultConverterRegistry" ... autowire="byType" >
which means Spring found two candidates for commonI18NService bean defaultCommonI18NService and defaultcustomCommonI18NService hence don't know which one to inject.
I propose to make your defaultcustomCommonI18NService a primary bean to be the autowired by using primary="true", see
<bean id="defaultCustomCommonI18NService" class="com.extended.service.impl.DefaultCustomCommonI18NService" parent="defaultCommonI18NService" primary="true" />

Failed to convert value of type '$Proxy55

I have my spring batch program written all was working fine until I tried refactoring the name of beans and respective class names only then I started getting below exception
Error creating bean with name
'org.springframework.batch.core.configuration.xml.SimpleFlowFactoryBean#3':
Cannot create inner bean '(inner bean)#6aed4066' of type
[org.springframework.batch.core.job.flow.support.StateTransition] while
setting bean property 'stateTransitions' with key [24]; nested exception is
org.springframework.beans.factory.BeanCreationException: Error creating bean

setting constructor argument; nested exception is
org.springframework.beans.factory.UnsatisfiedDependencyException: Error
creating bean with name '(inner bean)#7e1f1f61': Unsatisfied dependency
expressed through constructor argument with index 0 of type
[org.springframework.batch.core.Step]: Could not convert constructor
argument value of type [$Proxy55] to...
So I am trying to understand what $Proxy 55 is and why this exception is happening.

After examining id attribute of each spring bean in spring configuration file found that more than one spring bean had same id so after changing them to unique id the issue got resolved

Alfresco compatibility with Existing Oracle DB

I have installed Enterprise Version of alfresco and trying to use it with existing Oracle DB schema.
For that I have changed properties in alfresco-global.properties file from PostgreSQL to Oracle.
And I am getting authenticate error while login into alfresco admin.

Invalid property 'priority' of bean class [org.quartz.CronTrigger]: Bean property 'priority' is not writable or has an invalid setter method

Error in SpringFramework 3.x with Quartz 2.x.x
deploy failed WAR file in Jboss 5.2.0 environment
the error
ERROR [org.springframework.web.context.ContextLoader] Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'artifactBatchTrigger' defined in class path resource [applicationContext-quartz.xml]: Invocation of init method failed; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'priority' of bean class [org.quartz.CronTrigger]: Bean property 'priority' is not writable or has an invalid setter method.
Does the parameter type of the setter match the return type of the getter?
the xml file config spring
....
<bean name="artifactBatchTask"
class="it.infocamere.middleware.mccplus.quartz.ArtifactBatchTask">
<property name="batchService" ref="artifactBatchService" />
</bean>
......
I suppose a conflict libraries quart with spring.
thank you

including hibernate-validator breaks existing hibernate configuration

I am writing a java module in which I have used hibernate validator. The module works fine by itself.
However when it is included as part of a parent project which uses hibernate for standard entity mapping as an ORM, the parent module breaks down by complaining that it is unable to set up the validation factory (and thus fails to setup the session factory).
exception message is "Invocation of init method failed; nested exception is org.hibernate.HibernateException: Unable to get the default Bean Validation factory"
-Pulkit
EDIT:
hibernate-validator : 4.3.1.Final
hibernate-core : 3.6.5
