I've been trying to use spring with jboss portal.
I've configured velocityResolver and velocityConfigurer, I've configured ViewRendererServlet and found that in AbstractTemplateView there is code:

private static boolean responseGetContentTypeAvailable;

static {
// Determine whether the Servlet 2.4 ServletResponse.getContentType method
// is available.
try {
ServletResponse.class.getMethod("getContentType", new Class[] {});
responseGetContentTypeAvailable = true;
}
catch (NoSuchMethodException ex) {
responseGetContentTypeAvailable = false;
}
}

http://springframework.cvs.sourceforge.net/springframework/spring/src/org/springframework/web/servlet/view/AbstractTemplateView.java?revision=1.13&view=markup

However in JBoss Portal there is:
  public String getContentType()
  {
  throw new UnsupportedOperationException("Not specified by spec");
  }

http://fisheye.labs.jboss.com/viewrep/JBoss/jboss-portal/portlet/src/main/org/jboss/portal/portlet/impl/jsr168/DispatchedHttpServletResponse.java?r=1.1

Shouldn't spring code tries to call getContentType when found and handle other exceptions?

I know that I can reimplement my templte view however it would be still good if we could use as much as possible out of the box.
