title: setup of eclipse project : tomcat server , jdk , external libraries and so on
body: <p>I'm a beginner java developer and i'm not very confident with java world tools.</p>
  
  <p>i'm using eclipse helios, jsdk 1.5, axis2 plugin and tomcat 6.0.29 on windows to port a very old webservice , preaviosuly deployed on a websphere.
  I've added a tomcat server to my eclipse project, when i start the server i get the following message : the APR based Apache Tomcat Native library  ... etc ... was not found on the java.library.path .
  How do i change that variable (or any environment variable in general ) from inside eclipse ?</p>
  
  <p>Then i've another problem i don't know if can be solved with some kind of configuration : i must use some third party .class library grouped togheter into a zip file. I've added the zip to the shared.loader property of the tomcat catalina.properties file and my project can't see them. If i rename the .zip file to .jar everything works fine . How can i use classes inside zip file without renaming it to jar ?  </p>
  
  <p>thank you in advance</p>
