Ошибка при запуске tomcat приложения на VPS

Написал небольшое приложение на Java (Spring MVC) которое запускаю с помощью Tomcat из Intellij IDEA. Получил VPS сервер (Ubuntu 14.04), установил на нем томкат (страница Tomcat Web Application Manager работает), залил проект в директорию /var/lib/tomcat7/webapps/ и в менеджере томката появился url моего приложения но когда перехожу на этот url получаю
HTTP Status 404 - /YaPokupay/ description The requested resource is not available.
Локально на localhost все нормально запускалось.
Если необходима дополнительная информация по теме - с радостью предоставлю.
На всякий случай web.xml:

encoding-filter org.springframework.web.filter.CharacterEncodingFilter encoding UTF-8 forceEncoding true
encoding-filter /*

Ответ

Проблема оказалась в несоответствии версий java на VPS и локальной машине. Для решения необходимо произвести следующие действия:
удалить java на ПК и на сервере скачать последнюю версию jdk с официального сайта установить эту версию на ПК и на сервере (инструкции есть в интернете, например здесь) далее в файле /etc/init.d/tomcat7 в строчке c JDK_DIRS указываем путь к ранее установленной jdk, у меня установлена здесь: JDK_DIRS="/opt/jdk/jdk1.8.0_112" перезапускаем томкат радуемся
