Looks to me like you're missing ehcache.jar from your WEB-INF/lib directory.

First of all, regarding the error you have about cannot open the applicationContext.xml... check that you have it referenced under the right place. To do this, check your build.xml and also under the webapps directory after it has been exploded. Most likely it's not there.
Regarding the stack trace dump that you have about the EhCaching, you need to drop the EhCache.jar into your classpath for the build.
