> I have found four related problems.
> 1. In method "createPortletApplication" of class: org.apache.jetspeed.util.descriptor.PortletApplicationDescriptor,
the attribute of elements "display-name" and "description" should be xml:lang, not just lang,
for example:
> digester.addSetProperties("portlet-app/portlet/display-name", "lang", "language");
> 2. According to PLT.21.8.1, The default value for the xml:lang attribute is English (?en?).
Portlet-container implementations using localized values of these elements should treat the
English (?en?) values as the default fallback value for all other locales. So it is wrong
to use "Locale.getDefault()" in class org.apache.jetspeed.util.JetspeedLocale. In my environment(SIMPLIFIED_CHINESE),
it always cause many problems. So I think we should change as following:
>     /**
>      * According to PLT.21.8.1, the default locale should be English.
>      */
>     public static Locale getDefaultLocale()
>     {        
>         return Locale.ENGLISH;
>     } 
> 3. Enhance  PortletSelector to make it more robust.
> In method getRows(RenderRequest request, String sql, int windowSize, String filter) of
PortletSelector portlet. If the HttpServletRequest's locale (Client browser's locale) is not
supported by portlet's display-name or description, it will cause a NullPointException when
try to sort the portlets. so I suggest that if client browser's locale can be support, we
try to return the default locale display-name or description. So I change it as following:
> ......
> // Try to get the display-name of request locale. If can't, return the default English
locale display-name.
>                 String displayNameText = portlet.getDisplayNameText(locale);
>                 if(displayNameText == null || displayNameText.length() == 0)
>                     displayNameText = portlet.getDisplayNameText(Locale.ENGLISH);
>                 
>                 // Try to get the descriptionText of request locale. If can't, return
the default English locale display-name.
>                 String descriptionText = portlet.getDescriptionText(locale);
>                 if(descriptionText == null || descriptionText.length() == 0)
>                     descriptionText = portlet.getDescriptionText(Locale.ENGLISH);   
            
>                 
>                 list.add(new PortletInfo(appName + "::" + portlet.getName(), displayNameText,
descriptionText));
>             }            
>             BrowserIterator iterator = new PortletIterator(
>                     list, resultSetTitleList, resultSetTypeList,
>                     windowSize);
>             setBrowserIterator(request, iterator);
>             iterator.sort("Portlet");
>         }
> ......
> 4. I found many bundled portlets' portlet.xml aren't so standard in J2. They use lang
instead of xml:lang ererywhere.
