I just wanted to add spring framework to my project, But when i try to deploy my war file in jboss 6.1.0 Final, it gives a error. I get following error,
11:01:46,556 INFO [STDOUT] ERROR: org.springframework.web.context.ContextLoader - Context initializ
ation failed

I can see all the files compiled and assembled to the war file. Appreciate, if a spring guru can point me the reason for this deployment error.
Edit: Added DaoFactoryImpl

Update 2
The problem seems to be creating the JdbbcDaoFactoryimpl instance, When i removed the
<bean id="DAOFactory" class="com.tapgift.merchant.integration.db.dao.jdbc.JdbcDaoFactoryImpl" /> with its dependencies, i can deploy it without any problem. I checked the war file and all spring jars are belongs to same version. Need a help desperately.
Never mind, i was able to fix it, Slightly related to what Ajinkya showed.
Problem was
m_daoMap.put(((EntityBaseDao) dao).getEntityType().getName()on this code of JdbcDaoFactoryImpl.((EntityBaseDao) dao).getEntityType()was not returning any value but null. I forgot to override / remove particular method of actual dao implementation class. Once i removed that method, i was able to deploy it without facing any problem.Thank you for your support anyway.
