Developing a custom portlet

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

Sample code

If you do not want to use the HCL 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
        }
    }
}

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

Note

The impersonation feature becomes active with the next request.
