title: WSO2 API Manager - custom workflow don't work because carbon don't find the new class
body: <p>I'm working on WSO2 am and I'm trying to implement a custom workflow.
  I read all the documentation and many blog on it but nothing solve my pb.</p>
  
  <p>I add my jar with just my new class on <em>/repository/components/lib</em> </p>
  
  <p>After, I comment </p>
  
  <pre><code>&lt;!--SubscriptionCreation executor="org.wso2.carbon.apimgt.impl.workflow.SubscriptionCreationSimpleWorkflowExecutor"/--&gt; 
  </code></pre>
  
  <p>in <strong><em>/_system/governance/apimgt/applicationdata/workflow-extensions.xml</em></strong></p>
  
  <p>Finally, I add  this line </p>
  
  <pre><code>&lt;SubscriptionCreation executor="org.wso2.sample.workflow.Printer"/&gt;
  </code></pre>
  
  <p>to the same file.</p>
  
  <p>But when I try to add an application or to subscribe or anything using workflow, WSO2 crash because he don't find my class.</p>
  
  <p>Someone can help me ?
  Thank</p>
