I'm building a web application running on Liberty profile 8.5 using BIRT. The web application includes all BIRT needed libs in WEB-INF/lib folder, but I have the following exception in birt logs just when I run chart reports (not for text reports):

WARNING: Exception org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Package with uri 'http://www.birt.eclipse.org/ChartModel' not found. (file:///opt/IBM/WLP-8.5.5/usr/servers/IBMWTC/test.chart, 1, 314) at org.eclipse.emf.ecore.xmi.impl.XMLLoadImpl.handleErrors(XMLLoadImpl.java:77) at org.eclipse.emf.ecore.xmi.impl.XMLLoadImpl.load(XMLLoadImpl.java:185) at org.eclipse.emf.ecore.xmi.impl.XMLResourceImpl.doLoad(XMLResourceImpl.java:261) at org.eclipse.emf.ecore.resource.impl.ResourceImpl.load(ResourceImpl.java:1518) at org.eclipse.birt.chart.model.impl.SerializerImpl.fromXml(SerializerImpl.java:465) ... ...

The only way to make it working is to set the classloader to 'parentlast' in the server.xml: 

<webApplication ...>
    <classloader delegation="parentLast"/> 
</webApplication>

but this setting makes the application not working with other framework (as jsf 2.0 defined at server level through the related liberty feature).

    You already have a similar (and badly formatted question with answers by you that should be edits to your question) https://stackoverflow.com/questions/35984289/liberty-profile-birt-and-jsf-integration. Please learn how to ask good questions and how StackOverflow works – Kukeltje Mar 17 '16 at 08:08
  • I know about the other question, but here my intention was to focus just on birt exception. Just for this reason I've created a new more specific question. Sorry for the badly formatted question with answers. – Valery Mar 17 '16 at 08:29
