Cannot deploy application on Tomcat 7 Due to "invalid Lifecycle transition was attempted " error

Question

i've got aproblem! i'm trying to install my webapp on my tomcat server 7 installation but it keeps on saying that it cannot deploy my app due to "invalid Lifecycle transition was attempted".

here's my catalina log error:

org.apache.catalina.LifecycleException: An invalid Lifecycle transition was attempted       ([before_destroy]) for component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/myapp]] in state [STARTED]
at org.apache.catalina.util.LifecycleBase.invalidTransition(LifecycleBase.java:409)

at org.apache.catalina.startup.Catalina.stop(Catalina.java:765)
at org.apache.catalina.startup.Catalina$CatalinaShutdownHook.run(Catalina.java:910)

I've tryied even to delete manually "myapp" folder and ".war" into tomcat's webapp folder (after turning off tomcat) but it doesn't resolve anything.

i tryied also to redeploy my oldest .war files of the app but it won't start at all.

Someone has got any ideas?

thanks in advance

Maybe your JRE is using different web server vendor servlet api (javax.servlet.*). Try to check your System classpath.
