Re: [jetty-users] Question about ErrorHandler

[Silvio Bierman <sbierman@xxxxxxxxxxxxxxxxxx>]

    Thanks Greg.
    
    The errors are mostly generated from request handler code calling
    response.sendError(xxx). Part of these calls resides in generic
    library classes. We want to be able to generate error pages from our
    own application sites where context, styling and possibly language
    is defined.
    
    Should that attribute be set? What would be in it? Is that some
    unique identifier for the specific servlet instance?
    
    There is only one single Servlet class in the application and there
    is only one single instance of that class. I could get at it from
    that end but I would prefer to not explicitly depend on that being
    the case.
    
    But I feel a lot better now you tell me setting the attribute would
    be fine. I was just wondering if there was some standard way of
    getting at the Servlet instance.
    
    Cheers,
    
    Silvio

It depends a little bit on how the error was generated in the first place?

Is the request attribute "javax.servlet.error.servlet_name" set? if so, then you can use that name to lookup the servlet instance directly on the servlet handler.

But your request attribute technique is probably fine as well.
