I'm running a TomCat 7.0.11 everything worked fine, till I deployed a new .war file. Using the manager the only message I get is


but after refreshing the List of Applications no App appears. The TomCat tells me

.war file already exists

if trying to redeploy the .war

I'm not able to figure out where the problem is. Is it possible that my installation of TomCat is not compatible with Java 7?

what have you found out when reading the catalina.out log? – dawud Jun 4 '13 at 18:48

It was a compatibility problem. Updating the TomCat did the thing. Now TomCat v. 7.0.40 is running on my server and everything works fine!
