    XML schema file cannot be loaded

    Martin Ganserer Newbie

      Hello,

       

      I am facing a problem with our application that runs on Wildfly 16. A small part of this system is responsible for importing data in XML format from external applications. We want to validate the incoming content by using a XML schema file that is contained in the WEB-INF folder of our Java EE 8 application.

       

        SchemaFactory sf = SchemaFactory.newInstance(javax.xml.XMLConstants.W3C_XML_SCHEMA_NS_URI);

        Schema schema = sf.newSchema(new File(this.getClass().getClassLoader().getResource("schema/theschema.xsd").getPath()));

        unmarshaller.setSchema(schema);

       

      When testing the code an exception will be thrown:

      ...

       

      I am sure that the location of the file is valid as I am able to read the content from the file manually. Just the method newSchema() seems not being able to read it!

       

      Does somebody have an idea? Thank you in advance!

       

      Best regards
