Project Name: CarpoolDB, I have added the jar for this project in another application name Carpool. While running the Carpool app I am getting following exception.
Project: Carpool. Here i am getting exception as "carpoolService" not getting autowired while running as "Google Web application" but same runs under Tomcat and beans properly get injected.
@Controller
public class PlacesSearchController {
@Autowired
CarpoolService carpoolService=null;
public CarpoolService getCarpoolService() {
return carpoolService;
}
public void setCarpoolService(CarpoolService carpoolService) {
this.carpoolService = carpoolService;
}
}
carpool-application-context1.xml
Also I have applicationContext-security.xml, for spring security.

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
