<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal">I’m an engineer at Microsoft and my team would like to implement a Java writer plugin for our product.<o:p></o:p></p>
<p class="MsoNormal">I’ve tried to implement the simplest plugin but with no success. Didn’t find any proper documentation for Java plugins development either.<o:p></o:p></p>

<p class="MsoNormal"><b>Your prompt response will be highly appreciated as we’re going to GA very soon and this plugin will be highly valued for our customers.<o:p></o:p></b></p>
<p class="MsoNormal"><br>
I encounter the same error over and over again, that the class provided in the LoadPlugin element (collectd.config) was not found on the agent startup.<o:p></o:p></p>
<p class="MsoNormal">Here’s what I’ve done:<o:p></o:p></p>
