title: javac: package org.apache.poi.hssf.usermodel does not exist
body: <p>I have a program attempting to use classes from the <code>jakarta-poi-3.0.2.jar</code> in my /usr/share/java directory:</p>
  
  <pre><code>import org.apache.poi.hssf.usermodel.HSSFCell;
  import org.apache.poi.hssf.usermodel.HSSFCellStyle;
  import org.apache.poi.hssf.usermodel.HSSFWorkbook;
  etc...
  </code></pre>
  
  <p>When I compile, I get a <code>package org.apache.poi.hssf.usermodel does not exist</code> error for each of the imports above.</p>
  
  <p>I have /usr/share/java on my classpath.  Am I missing anything else?</p>
