Is there any body knows why these exceptions occurred in deploying liferay portlet  which uses hibernate-spring service of liferay  .
it is worth to note that it hasnt any problem in liferay5.1.1-tomcat-5.5 server in windows and works fine completely but throws exceptions in linux with similar configuration .
