  <p>I checked the jre version, paths, imports, jars and I found everything ok. I run also ant build for build.xml and demo.xml. I think the problem is somehow in the helloworld.config.xml but I can't figure it out.
  Here's the hello.config.xml file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
