[Springframework-developer] webflow, jetty request parameters

[Serge B. <ser...@gm...>]

Hi,


I am using jetty6. Jetty particular request parameters processing make it
impossible to use webflow with jetty. I do not sure this container to do things
in right way. But I have found we can make the webflow to run with jetty.

The weak spot in webflow is 'HttpServletRequestParameterMap.getAttribute(String
key)' method. It makes the following call:


request.getParameterValues(key);


Jetty returns String[0] for a unknown parameter. But this case is not provided.
This is original code:


        if (parameters == null) {

            return null;

        } else if (parameters.length == 1) {

            return parameters[0];

        } else {

            return parameters;

        }


Here is my variant:



        if (parameters == null) {

            return null;

                } else if (parameters.length == 0) {

                        return null;

        } else if (parameters.length == 1) {

            return parameters[0];

        } else {

            return parameters;

        }



I have found another small problem with webflow samples. All samples contains
invalid value for a 'webAppRootKey' context parameter in web.xml. For example,
in the sample phonebook the parameter value is "phonebook.root", but the valid
value is "swf-phonebook.root", because assebly artifact is "swf-phonebook.war".
