LeonardoLeonardo, in short, YES!
The exported .WAR file should be placed in the {tomcat directory}/webapps folder. Typically with auto deploy, you can just start Tomcat and be fine; however, have a look at this for details on deploy methods:
http://tomcat.apache.org/tomcat-5.5-doc/deployer-howto.htmlThe .WAR file should include all your referenced JAR files; however, to make sure I typically put these files in WEB-INF/lib within my project and reference them in my build path from there. I include Axis and Log4J JAR here unless you want same versions globally available, then you can put them in Tomcat's common/lib directory. Same applies for your JDBC JAR(s).
Here is a reference for Tomcat and Log4J:
http://tomcat.apache.org/tomcat-5.5-doc/logging.html(You would place the properties file into {tomcat directory}/common/classes directory under tomcat following this approach)
I unfortunately have tested mine manually, but should be able to use test cases in a framework like HttpUnit which is designed for web application unit testing.
