Someone knows which is the problem? Application works fine in Weblogic, but not in Tomcat. I have read in another site that cause can be JARs in classpath servlet-api.jar and others because those are in Tomcat library directory too. These JARs can't be removed from classpath baceuse they are necessary to project compilation.
Someone can help me?
P.S.: I'm spanish. Don't use strange words in ansrwers, please. English is not my mother tongue.
