That sounds like the Launch Configuration you're using to run your app
is referencing a JAR instead of the project directly. Eclipse doesn't
generally build JARs, so if the runtime classpath of a Launch
Configuration is pointed at a JAR, it won't see coding changes unless
you rebuild the JAR it's pointed to. The normal situation is that the
Launch Configuration references a project (or projects) directly, and
thus sees all code changes autoamtically (that's assuming that the
project builds successfully, of course).
The easiest way I can think of to test/remedy that is to delete the
Launch Configuration and re-create it by selecting the project or the
main class and choosing Run As... (that's assuming it's a "plain" Java
project; if it's some other kind of app then there are different, but
similar, ways to re-create the launch configuration).

That sounds like you have some build path error on the project. Eclipse
will report such errors in the Problems view, and in the Java Build Path
section of the project properties dialog.
