Question

I have an spring-hibernate web application running on tomcat server version 7.0.25 with jdk 1.6.0_25

I do not know why but even if I did not change anything about my code or server configurations, this morning I have started to get the following exception.

I would be great if you can share your ideas and solutions. Thanks in advance.

java.lang.NoClassDefFoundError: org/apache/juli/logging/UserDataHelper
