title: Open source Java library to build CIFS server
body: <p>We are planning to develop a <strong>CIFS server</strong> using Java. Note that this will be a <strong>commercial product</strong>.</p>
  
  <p>To avoid re-invention of wheel, I am looking for a open source Java library which can be used in commercial products without any legal issue. After research I found that <a href="http://www.alfresco.com/products/aifs/" rel="nofollow"><strong>Alfresco JLAN</strong></a> is the only Java open source library available on web. But problem I see is it's published under <strong>LGPL</strong> license. If I plan to use JLAN, I will need to make some changes in it's original source to make it compatible with my product, and after doing this, i guess, I will need to make my product as well GPL based.</p>
  
  <p>I need your expert opinion on following-</p>
  
  <ol>
  <li>Is there any way i can still use JLAN without any legal issue in my commercial product without any obligation to make my product open source?</li>
  <li>If not, then is there any other Java open source library which will fit my requirements?</li>
  </ol>
