j2ee.jar was probably compiled under Java 5. The Tomcat 6.0 servlet-api.jar was compiled under Java 6. When you call "javac" from the command line, it would seem you have a Java 5 compiler, which will be able to use j2ee.jar, but not the Tomcat 6 servlet-api.jar.
You should either look at Tomcat 5.5 for servlet-api.jar, or consider upgrading your JDK to Java 6.
