Accessing Query String parameter in WebSphere Portal with Dynacache

1) Create a jar of below class

import com.ibm.websphere.cache.DistributedMap;
import java.io.IOException;
import java.util.Enumeration;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.naming.InitialContext;

private DistributedMap map;

public ParameterFilter()
{
map = null;
}

public void init(FilterConfig arg0)
throws ServletException
{
try
{
InitialContext ic = new InitialContext();
map = (DistributedMap)ic.lookup("services/cache/catalog/parameters");
ic.close();
}
catch(NamingException ne)
{
logger.log(Level.SEVERE, "NamingException error", ne);
}
}

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException
{
HttpServletRequest httpRequest = (HttpServletRequest)request;
HttpSession session = httpRequest.getSession();
Enumeration parms = httpRequest.getParameterNames();
if(logger.isLoggable(Level.INFO))
logger.log(Level.INFO, "Parameter prefix: param.");
while(parms.hasMoreElements())
{
String key = (String)parms.nextElement();
if(key != null && key.startsWith("param."))
{

}

}
}
if(chain != null)
chain.doFilter(request, response);
}

public void destroy()
{
}

}
-------------------------------------------------------------------------------------
2)Create Dynacache
JNDI name: services/cache/catalog/parameters

3)Add the following code to the web.xml file:

<filter>
<filter-name>Parameter Filter
<filter-class>
com.ibm.catalog.servlet.filter.ParameterFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>
Parameter Filter

</filter-mapping>
<filter-mapping>
<filter-name>
Parameter Filter
</filter-name>
