RE: [J2] Passing attributes from a portlet to a servlet...
Hi all,
There is a problem in my program, does it the same topic about this
article?
My J2 is version 2.1.3 and tomcat is 5.5.23.
The following is the detail of my question:
When user login into my Portal, I've set some attributes in HttpSession
at LoginRedirectorServlet, and I hope those attributes could be access
in my portlets in my portlet-application.
now, my portlets can not get those attributes in Portlet or JSP,
in my Portlet doView method, my code like that
String my_attribute = (String) renderRequest.getPortletSession().
getAttribute("my-attribute",
PortletSession.APPLICATION_SCOPE);
in my JSP, the code like that
<%@ taglib uri='/WEB-INF/tld/portlet.tld' prefix='portlet' %>
<portlet:defineObjects/>
<%
Enumeration psans = renderRequest.getPortletSession()
.getAttributeNames(PortletSession.APPLICATION_SCOPE);
while(psans.hasMoreElements()){
String psan = (String) psans.nextElement();
out.print("\n " + psan + "=" + renderRequest.getPortletSession()
.getAttribute(psan,
PortletSession.APPLICATION_SCOPE));
}
%>
I've set the emptySessionPath="true" in my tomcat sever.xml like that
<Connector port="8080" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true"
emptySessionPath="true" />
but I still can not get the session attributes in my Portlets,
does it the same thing about this article?
and what should I do to fix my porblem?
Regards,
Bon

You are setting attributes in the Jetspeed application's session,
which is different from your portlet application's session. The
servlet spec requires that these attributes are not shared between
applications.
What you can try to do is set a request attribute on the jetspeed
request (servlet) in your login redirector servlet, and then grab the
attribute in your portlet with something like:
Object attribute = null;
Enumeration attributes = renderRequest.getAttributeNames();
while (attributes.hasMoreElements())
{
String name = (String)attributes.nextElement();
attribute = renderRequest.getAttribute(name);
if (attribute!=null)
{
out.print(name + " = " + attribute + "<br/>");
}
}
You may need to set the request attribute in jetspeed after the
redirect, preferably in a valve
