I have two web projects. One web projects is using some classes of
the other project. I have marked the depended project and set the
smart deployment of on. But when i deploy the project, the classes
of the depended project are not deployed.

I am using the 3.8 version and tomcat 5.0.27

Web projects cannot be deployed as dependent of eachother, there is no common 'rule' knowing how to combine the projects into eachother. You can however (and this is the suggested way) break out the common classes into a base Java Project that is marked as dependent of the two web projects, THEN it will be deployed correctly with the web projects.

Okay, thanks for your help
