POJava plugin framework choice

copied!<p>We're trying to determine how to implement a simple plugin framework for a service we are implementing that allows different types of calculators to be "plugged-in".</p> <p>After reading a <a href="https://stackoverflow.com/questions/tagged/plugin-architecture">number</a> of posts about Java plugin frameworks, it seems like the most common options are: </p> <ul> <li><a href="http://www.osgi.org/Main/HomePage" rel="nofollow noreferrer">OSGI</a></li> <li>"<a href="https://stackoverflow.com/questions/465099/best-way-to-build-a-plugin-system-with-java/465143#465143">Rolling your own</a>" plugin framework</li> <li>The <a href="http://jpf.sourceforge.net/about.html" rel="nofollow noreferrer">Java Plugin Framework</a> (JPF)</li> <li>The <a href="http://code.google.com/p/jspf/" rel="nofollow noreferrer">Java Simple Plugin Framework</a> (JSPF)</li> </ul> <p>OSGI seems to be more than we need.</p> <p>"Rolling your own" is ok but it would be nice to reuse a common library.</p> <p>So we're down to the JPF and JSPF. JPF doesn't seem to be in active development anymore.</p> <p>JSPF seems very simple and really all we need. However I haven't heard much about it. I've only seen one <a href="https://stackoverflow.com/questions/81495/best-technology-for-adding-plugin-support-to-a-j2se-application/82108#82108">post</a> on StackOverflow about it. Does anyone else have any experience with JSPF? Or any other comments on this design choice? </p> <hr> <p><strong>Update</strong>: There isn't necessarily a correct answer to this.. however we're going to go with Pavol's idea as we need just a really, really simple solution. Thanks EoH for the nice guide.</p>
