Hello there,
I have eclipse with tomcat. I am new to eclipse and I come from netbeans! Smile

So far I really like it, but this one things drive me nutts:

I set my build path libraries. However, I noticed that even if I remove all my libraries from "Build Path", the project still compiles properly - i.e. it seems to ignore the build path and loads libraries from somewhere else.... where can I find this "somewhere else"? (However, the code editor itself marks them as incorrect (class not found exceptions), but the compiler still builds?)

Also, there is a deployment path when I click on "run confuguration". Should I put all the libraries of my project in there?? When I run it keeps saying things like "ClassNotFoundException: org.apache.commons.logging.Log" even though commons-logging.jar is in the project Build Path... This forces me to put it in the Deployment Path, but this makes no sense... generally I don't have to do that with external tomcat.

Can someone please help me clear this up??? What is going on????

Actually, a more specific question is:
What is the difference between "Build Path" and "Deployment Assembly"

It looks like some libraries need to be in the build path, and others need to be also added int he deployment assembly.

Thanks!!

Hi Mike,
Projects can be compiled from Class path settings, Check out Window-> Preferences -> Java -> Build Path-> Classpath Variables.

Run Confriguration, takes the settings from the Project, it can be edited if you want a different setting for compile and run time.
Hope it helps.
