<p>Hello everyone, </p>
<p> </p>
<p> Recently I installed Windows 8.1 and now my BIRT version 4_2.2 is giving me an error. The error is: </p>
<p> </p>
<p>"</p>
<div>HTTP ERROR: 500</div>
<div>Problem accessing /viewer/preview. Reason: </div>
<div> </div>
<div> Plug-in "org.eclipse.birt.report.viewer" was unable to instantiate class "org.eclipse.birt.report.servlet.BirtEngineServlet".</div>
<div> </div>
<div>
</div>
<div>Powered by Jetty:// </div>
<p>"</p>
<p> </p>
<p>Any ideas? Any suggestions to have BIRT running agian? I have searched online for simmilar problems and no luck on my end.</p>
<p> </p>
