hi..

let's say i have a web project which depends on a java project which depends on a jar in it's class path.

if i try to use a class from java project that uses the jar, i will get a ClassNotFoundsException, is there anyway to have eclipse include that jar in the web class path? without actually inserting in the lib folder? i've tried everything, including specify order and export and use deployment assembly..

the only thing i can think of is include the jar in the server class path launcher..(which does work).

You should be able to consume that other project as a Web App Library.
Do this:

1) Right-click your (Dynamic Web) project.
2) Choose Build Path -> Configure Build Path...
3) Click the Libraries tab.
4) Click Add Library...
5) Select Web App Libraries and click Next.
6) Select the project whose libraries (JARs) you wish to consume.

It should be obvious from there.

Hope this answers your question.
