[jboss-user] [JBoss Portal] - NPE using JSTL format

[PeterJ]

Trying to use the format taglib in a JSP within a portlet.  But use of f:message leads to:

2006-08-08 16:27:05,734 ERROR [org.jboss.portal.core.command.ControllerCommand] Rendering portlet window default.default.ImagePortletWindow triggered the following error :

Looking at the Util class, I see:

public static Enumeration getRequestLocales(HttpServletRequest request) {
  |   Enumeration values = request.getHeaders("accept-language");
  |   if (values.hasMoreElements()) {                                       //<== line 281
  |     // At least one "accept-language". Simply return
  |     // the enumeration returned by request.getLocales().
  |     // System.out.println("At least one accept-language");
  |     return request.getLocales();
  |   } else {
  |     // No header for "accept-language". Simply return
  |     // the empty enumeration.
  |     // System.out.println("No accept-language");
  |     return values;
  |   }
  | }

It appears that the portal is stripping the language sent by the browser, and thus returning a null when asked for "accept-language".  I even added a supported-locale entry in my portal.xml file, but still get the same NPE.

Does anyone have a JSP using the format JSTL and it works?
