I am getting a 500 error from my Spring web application. The mentioned files are correctly named and in the correct packages. Here is the error message.
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping': Invocation of init method failed; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.dao.CommentDAO] for bean with name 'commentDAO' defined in ServletContext resource [/WEB-INF/ghs1986-servlet.xml]; nested exception is java.lang.ClassNotFoundException: com.dao.CommentDAO

Here is the relevant portion of ghs1986-servlet.xml.
<bean id="commentDAO" class="com.dao.CommentDAO">

</bean>
<bean id="pagesController" class="com.controller.PagesController" />
<bean id="commentController" class="com.controller.CommentController">
<property name="commentDAO" ref="commentDAO" />
</bean>
Problem solved. I needed the #Component annotation on CommentDAO.

So it looks like you are having a problem with your hibernate configuration.
The last line of your stacktrace shows a NullPointerException.
In eclipse or InteliJ you can set Exception breakpoints.
Set one for NullPointerException and debug the startup. You may see some NullPointerExceptions not related to your problem, but finally you will see the one that is terminating startup. Once you found the location where it happens its mostly easy to find a solution..

Your bean is declared as
<bean id="myServiceCustomerOffer" name="myServiceCustomerOfferName" class="com.abcd.mime.ws.manage.customeroffer.ManageCustomerOfferImpl" >
<constructor-arg index="0" ref="CustomerOfferFacade" />
</bean>
That means it will use a constructor that expects an argument of whatever type the CustomerOfferFacade is. However, your class doesn't have such a constructor. It therefore fails.
I don't know what CustomerOfferFacadeImpl is so I don't know what you're expecting to do with it, but you'll need to add a constructor with a parameter of that type if you want your <bean> declaration to work.

The server is running at http://localhost:8888/
Why I am getting as
1. java.lang.NoClassDefFoundError: java.io.FileOutputStream is a restricted class.
I am not writing anything on file
GAE doesn't support few API that I am aware of but my application already working for MySQL and I want to support both. I mean based on property set in my property file I want to use sometime MySQL and sometime want to work with GAE datastore.
I am using spring 3.
What I should do in this case?
As Boris notes, the issue appears to be with your session factory. GAE doesn't support jdbc, and it looks like your sessionFactory is configured for mysql:
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect"><!--Which dialect is used of hibernate according to type of underlying database-->
org.hibernate.dialect.MySQLDialect
</prop>
<prop key="hibernate.show_sql">false</prop>
</props>
</property>
If you're working with an existing codebase that depends on Hibernate, you could try configuring Hibernate to run backed by Cloud SQL: https://developers.google.com/appengine/articles/using_hibernate
As for the FileOutputStream issue, I believe one of the default appenders for log4j is a FileAppender, so simply not configuring log4j won't fix it - you'll need to explicitly configure it. See if this page helps: http://blog.xam.de/2010/03/logging-in-google-appengine-for-java.html
