Samebug tips


This is thrown when the JVM tries to load a particular class and the specified class cannot be found in the classpath. Make sure Apache commons-lang library jar is added to your project's build path and you are using commons-lang3-3.0.jar or greater.


Make sure to add org.springframework.core-3.1.0.M2.jar to your project libraries so that org.springframework.core.env.EnvironmentCapable will be loaded.
