Hello,<div><br></div><div>I&#39;m trying to execute some examples of GEP extension for EJC developed by Bob Orchard but i&#39;m having some problems.</div><div><br></div><div>After search some parameter files like &quot;gep.params&quot; and &quot;ec.params&quot; and found it on <a href="http://koders.com">koders.com</a>, i modify the test1.param example of GEP examples in order to make the example works.</div>

<div><br></div><div>The problem now is that ECJ can&#39;t find the class &quot;<span class="Apple-style-span" style="border-collapse: collapse; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px; ">GEPSimpleStatistics&quot;, that, in the test1.param file is mentioned to be used by ECJ:</span></div>

<div><span class="Apple-style-span" style="border-collapse: collapse; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px;"><br></span></div><div><span class="Apple-style-span" style="border-collapse: collapse; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px;">state = ec.gep.GEPSimpleStatistics</span></div>

<div><span class="Apple-style-span" style="border-collapse: collapse; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px;"><br></span></div><div><span class="Apple-style-span" style="border-collapse: collapse; white-space: pre; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px;">The output that i obtain is the next:</span></div>
