Subject [jira] Resolved: (JS2-660) Request attribute not available in jsp when using the JetspeedPowerTool
Date Fri, 11 May 2007 18:49:15 GMT

     [ https://issues.apache.org/jira/browse/JS2-660?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

David Sean Taylor resolved JS2-660.
-----------------------------------

    Resolution: Fixed

I am checking Woonsan's patch, as his team has been doing in-depth parallel load testing and
uncovered issues related to 660.
Summary:
- added getAttributeNames() method and removeAttribute() method for org.apache.jetspeed.engine.servlet.ServletRequestImpl.
- added cachedAttributes member to cache request attribute map.
   If no attribute is added, changed, or removed, the cached map will be used in jsp pages.
- added another routine for getting attribute in getAttribute() method.
  Because PortletRequestImpl class of pluto encodes the name of attribute before calling setAttribute(),
we have to check the encoded name also.

I reviewed Nicolas's patch. It is close to Woonsan's code, but there is extra code (2 lines)
from Nicolas... 
Not clear to me why this is needed, as "pr" is not used. Commenting out for now...

PortletRequest pr = (PortletRequest) super.getAttribute("javax.portlet.request");
if (pr != null)

Nicolas, could you please test and see if this works for you now?

> The request attributes set in a portlet are not available inside a jsp after an "include"
when the portlet is inserted in the header.vm with JetspeedPowerTool.
> For example I have the foolowing code in a portlet doView :
>     request.setAttribute("test", "hello");
>     getPortletContext().getRequestDispatcher("/test.jsp").include(request, response);
> test.jsp contains :
>     ${test}
> And in header.vm :
>     $jetspeed.renderPortletEntity("testportlet", "portlets::TestPortlet")
> The value of attribute "test" is not visible. It works fine if the portlet is included
in a psml.
> I suggest the following correction in the class org.apache.jetspeed.engine.servlet.ServletRequestImpl,
in the method getAttribute(String) : 
> Replace : 
>     public Object getAttribute( String name )
>     {
>         Object value = null;
>         // In parallel mode, first look up from the worker.
>         Thread ct = Thread.currentThread();
>         if (ct instanceof Worker)
>         {
>             value = CurrentWorkerContext.getAttribute(name);
>         }
>         ...
> With : 
>     public Object getAttribute( String name )
>     {
>         Object value = null;
>         // In parallel mode, first look up from the worker.
>         Thread ct = Thread.currentThread();
>         if (ct instanceof Worker)
>         {
>             value = CurrentWorkerContext.getAttribute(name);
>             if (null == value)
>             {
>                 PortletRequest pr = (PortletRequest) super.getAttribute("javax.portlet.request");
>                 if (pr != null)
>                 {
>                     value = CurrentWorkerContext.getAttribute(nameSpaceMapper.encode(portletWindow.getId(),
>                             name));
>                 }
>             }
>         }
>         ....
