RE: [ULC-developer] ServletContainerContext.getHttpSession().invalidate()

[Etienne Studer]

Hi Janak

Thanks for the code and the quick reply. I had to modify the code a
little bit to make it work (see below), mainly moving the invalidate()
call to the handleRequestContent() method, but now it works fine.

Thanks and regards, Etienne

public class ULCCarinaServletContainerAdapter extends
ServletContainerAdapter {
    public void init() throws ServletException {
        _helper = new
CarinaServletContainerAdapterHelper(getServletConfig());
    }

    protected void service(HttpServletRequest inRequest,
HttpServletResponse inResponse) throws ServletException, IOException {
        if (!_helper.service(inRequest, inResponse, getServletConfig()))
{
            super.service(inRequest, inResponse);
        }
    }

    public class CarinaServletContainerAdapterHelper extends
ServletContainerAdapterHelper {
        public CarinaServletContainerAdapterHelper(ServletConfig
inServletConfig) {
            super(inServletConfig);
        }

        protected ContainerCommand createStopCommand() throws
ServletException {
            return new CarinaRemoveSessionCommand(this);
        }
    }

    public class CarinaRemoveSessionCommand extends RemoveSessionCommand
{
        public CarinaRemoveSessionCommand(ICommandInfo inCommandInfo) {
            super(inCommandInfo);
        }

        protected void handleRequestContent(IObjectInputStream inStream)
throws ServletException, IOException {
            super.handleRequestContent(inStream);
            ServletContainerContext.getHttpSession().invalidate();
        }
    }

    private ServletContainerAdapterHelper _helper;
}

ServletContainerContext.getHttpSession().invalidate()

Hi Etienne

There is already an issue: https://www.canoo.com/jira/browse/UBA-807.

It is not safe to invalidate the session at the application level in
IApplication#stop(). Even after the stop request, there is still some
protocol left at the connector level.

So, to invalidate the session you will need to extend
ServletContainerAdapterHelper:

public class YourServletContainerAdapter extends HttpServlet {
    private YourServletContainerAdapterHelper fHelper;

    public void init() throws ServletException {
        fHelper = new
YourServletContainerAdapterHelper(getServletConfig());
    }

    protected void service(HttpServletRequest request,
HttpServletResponse
response) throws ServletException, IOException {
        if (!fHelper.service(request, response, getServletConfig())) {
            super.service(request, response);
        }
    }
}


public class YourServletContainerAdapterHelper extends
ServletContainerAdapterHelper {
  protected ContainerCommand createStopCommand() throws ServletException
{
        return new YourRemoveSessionCommand(this);
    }
}

public class YourRemoveSessionCommand extends RemoveSessionCommand {
    public YourRemoveSessionCommand(ICommandInfo commandInfo) {
        super(commandInfo);
>>>>>>  ServletContainerContext.getHttpSession().invalidate();
    }

    protected void handleRequestContent(IObjectInputStream in) throws
ServletException, IOException {
        super.handleRequestContent(in);
    }
}

I hope this helps.

Thanks and regards,

Janak

Hi ULC Team

Is it safe to call ServletContainerContext.getHttpSession().invalidate()
within IApplication#stop()?

Thanks, Etienne
