How to scan hibernate entities package in struts2,spring3 application instead of using cfg.xml - spring

Question

I know this question may be a duplicate. I saw the link
[How to scan packages for Hibernate entities instead of using hbm.xml?
In my application using Struts2,hibernate3,and spring3
though I successfully removed the xml file for DAO and Service via <context:component-scan> in applicationcontext.xml, when I tried to use
<property name="packagesToScan" value="com.iris.admin"></property> it throws some typeNotMatchException and `Session factory BeanCreationException
Below is My Configuration File
...............hibernate.cfg.xml............................................
<hibernate-configuration>
<session-factory>
<mapping class="com.vaib.admin.languageMaster.bean.Menu" />
<mapping class="com.vaib.admin.companyType.bean.CompanyType" />
<mapping class="com.vaib.admin.companyType.bean.CompanyTypeModified" />
</session-factory>

I couldn't understand why it comes while in seperate application it works fine when i am using packageTOScan attribute
Thanks in advance.

Answer 1

The root cause is :
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'dataSource' is defined
You have commented line
<!-- <import resource="applicationContext-datasource.xml" /> -->
Remove the comment and it should work fine
