title: eclipse helios: tomcat project - jar will not be exported or published. runtime ClassNotFoundExceptions may result
body: <p>I'm using Eclipse Helios and I was wondering how can I add a library project to my folder that will be copied to the build directory where my compiled project resides.</p>
  
  <p>currently I did the following:</p>
  
  <ol>
  <li>created a lib directory in the root of my project</li>
  <li>copied the relevant jars to that dir</li>
  <li>My Project -> properties -> Java Build Path -> add jars and I added all the jars from that directory.</li>
  </ol>
  
  <p>after adding all the jars i got the following warning regarding each of the jar file:</p>
  
  <pre><code>jar will not be exported or published. runtime ClassNotFoundExceptions may result
  </code></pre>
  
  <p>first of all how can I add the directory of the jars instead of individual jars?
  and the 2nd question is how can I do that the libraries will be deployed properly when compiling my application ?!</p>
