When trying to deploy my application on tomcat 5.5 I get the following error: SEVERE: Error configuring application listener of class br.gov.fazenda.ouvidoria.sisouvidor.listener.ApplicationListener java.lang.UnsupportedClassVersionError: Bad version number in .class file
I was compiling my application using JDK 1.6 but I changed that to 1.5.0_11, which is the same as the one my tomcat server is using. I'm still getting the same error. Could anyone tell me if there is anything else that causes this error?
