Spring Applications

Only the following subset of the spring packages (Spring Framework version 3.1.0) are delivered with AS:
org.springframework.ws spring-xml (version : 2.0.3.RELEASE)
org.springframework spring-core (version : 3.1.0)
org.springframework spring-beans (version : 3.1.0)
org.springframework spring-context (version : 3.1.0)
org.springframework spring-web (version : 3.1.0)
If the Application needs any other spring packages, then those need to be deployed with application itself.
Projects which are built with Spring 2.5 or higher versions will be backward compatible with delivered version of Spring Framework. However, it is recommended to build your application with Spring 3.1.0 before deployment.
If the Application is based on a higher version of Spring framework, then that version needs to be deployed with the application. The framework which is deployed with the application will be given the priority in the run time.

The following sub packages of Spring 3.0.7 are shipped with the Application Server CXF environment.
spring-aop
spring-asm
spring-beans
spring-context
spring-core
spring-expression
spring-web
If the user wants to upgrade the Spring versions, one of the following actions can be carried out:
Remove existing Spring JARs from <product_home>/lib/runtimes/cxf directory and replace them with the new JARs.
Include the required JARs inside the WEB-INF/lib directory of the application and deploy it in the Tomcat runtime environment.
