在liferay中使用mysql時發生錯誤

我正在使用Liferay v6.1 CE。我按照this page和其他類似頁面上的說明，從Liferay的HSQL切換到MySQL v5.1.23。但是，當我啓動服務器時，我在瀏覽器中遇到以下錯誤，我認爲這與Tomcat有關。我有Apache Tomcat 7.0.23 btw。在liferay中使用mysql時發生錯誤

我portal-ext.properties代碼：

jdbc.default.driverClassName=com.mysql.jdbc.Driver 
jdbc.default.url=jdbc:mysql://localhost/liferaydb2?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false 
jdbc.default.username=root 
jdbc.default.password=theroot

錯誤，我在瀏覽器中得到：

HTTP Status 500 -
