Develop a custom portlet

Use the default Impersonation portlet to impersonate specific users. Alternatively, we can create a resource environment provider to enable impersonation and develop a custom portlet for impersonating users.

Sample code

If we do not want to use the WebSphere Portal Impersonation portlet, use the following sample to develop a portlet to impersonate users:

import com.ibm.portal.portlet.service.impersonation.ImpersonationService;
import com.ibm.portal.portlet.service.PortletServiceHome;
 public class MyImpersonationPortlet extends GenericPortlet
{
    private PortletServiceHome psh;
     @Override
    public void init() throws PortletException
    {
        try
        {
            javax.naming.Context ctx = new javax.naming.InitialContext();
            psh = (PortletServiceHome) ctx.lookup(ImpersonationService.
JNDI_NAME);
        } catch (Exception ex)
        {
            // error handling         }
    }
     @Override
    public void processAction(ActionRequest request, ActionResponse response) throws PortletException, IOException     {
        // obtain the service object and use the service         
        ImpersonationService impersonationService = (ImpersonationService) psh.getPortletService(ImpersonationService.class);
        try
        {
            impersonationService.doImpersonate(request, response, stringuserDN);
        } catch (Exception e)
        {
            // error handling         
        }
    }
}

We can enter the information for the user to impersonate in the stringuserDN. Alternatively, use the PUMA SPI User object.

The impersonation feature becomes active with the next request.
