null: net.sf.jasperreports.engine.JRException: Class not found when loading object from InputStream 
Caused by: java.lang.ClassNotFoundException: net.sf.jasperreports.components.html.HtmlComponent from [Module "deployment.myproject.war:main" from Service Module Loader]

Hi, Have you added the HTML component JAR to the classpath of your application that is running the reports? The JAR can be built from the /demo/samples/htmlcomponent either using the >ant jar command. I hope this helps. Teodor

You can also grab the jar from the Jaspersoft Studio download. Just search for the htmlcomponent.jar once you've downloaded it.
