If I create nodetype, say exo:image, with child node to hold an image, and use DisplayResourceCommand for this inner resource to display it as the image, DisplayResourceCommand throws "Invalid node type, expected nt:file or exo:article, have exo:image at /test" exception.

Massimo Gai proposed a solution:

• Node content;
• if(file.isNodeType("nt:file")) { - content = file.getNode("jcr:content"); - } else if(file.isNodeType("exo:article")) { - content = file.getNode("exo:image"); - } else
• throw new Exception("Invalid node type, expected nt:file or exo:article, have "+file.getPrimaryNodeType().getName
  ()+" at "+file.getPath());
  + String relativePath=(String)request.getParameter("relativePath");
  + Node content=file.getNode(relativePath);
  + if (content==null ) { + throw new Exception("Path not found: " + file.getPath() + "/" + file.getPrimaryNodeType().getName() + "/" + rela tivePath); + }

Property data = content.getProperty("jcr:data");
String mime = content.getProperty("jcr:mimeType").getString();

Note, extending nt:file or nesting nt:file does not work either.
