Nightmare: Upgrading Tomcat 5.5 to 6.0

I am trying to upgrade a perfectly working embedded Tomcat 5.5 to Tomcat 6.0. I understand that all I need to do is replace Tomcat 5.5 jars 6.0. This is what I did.

So, I replaced the following banks:

catalina-5.0.28.jar catalina-5.5.9.jar catalina-optional-5.5.9.jar 
commons-el.jar commons-modeler-1.1.0.jar jasper-compiler-jdt.jar 
jasper-compiler.jar jasper-runtime.jar jmx-5.0.28.jar jsp-api-2.0.jar 
naming-factory.jar naming-resources.jar servlet-api-2.4.jar 
servlets-default.jar tomcat-coyote.jar tomcat-http.jar tomcat-util.jar

with:

annotations-api.jar  catalina.jar    jasper.jar         tomcat-dbcp.jar
catalina-ant.jar     el-api.jar      jsp-api.jar        tomcat-i18n-es.jar
catalina-ha.jar      jasper-el.jar   servlet-api.jar    tomcat-i18n-fr.jar
catalina-tribes.jar  jasper-jdt.jar  tomcat-coyote.jar  tomcat-i18n-ja.jar
tomcat-juli.jar

As soon as I start the server, I get the following message in the logs at the INFO level:

INFO: Starting Servlet Engine: Apache Tomcat/6.0.29
Dec 31, 2010 6:04:18 AM org.apache.catalina.loader.WebappClassLoader validateJarFile
INFO: validateJarFile(/usr/local/blah/blue/./WEB-INF/lib/servlet-api.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class

Based on this explanation, I need to delete the jar file with the conflicting Servlet.class. I swear to God, there is no other inconsistent jar file, I am grepped system wide for Servlet.class, it matched only servlet-api.jar.

I also downloaded javaee.jar and replaced it with servlet-api.jar, with the same help.

You must take care of the context of the web application you deployed the application to. In the log, I see that you are using the root context. It's true? If, for example, you said

  tomcat.addWebapp("foo", appBase);

in your embed, you should request / foo / servlet, not / servlet in your browser.
