How to references correctly Java Projects into Web Dynamic Project

Question

I have an eclipse Java Project MyProject with the package com.myproj , that uses some libraries: xstream and jfreechart . I have also an eclipse Web Dynamic Project WebProject with the package com.webproj , that depends on some classes in com.myproj and that uses the library jfreechart .

The MyProject works perfectly.

In the Java Build Path of the WebProject there is the MyProject , and MyProject is also in the Deployment Assembly.

But every time I run the WebProject it can't start because of an ClassNotFoundException related to xstream , after this:

java.lang.ClassNotFoundException: com.thoughtworks.xstream.io.HierarchicalStreamDriver at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1714) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1559)

Answer 1

Now add all the XStream related dependencies, which are present in your Java project, in your web project as well.

Answer 2

When you run WebProject, make sure that is also build the dependent projects (MyProject). My guess is that it only cleans the projects.
