Doh!

where the validate method is declared as

ActionContext ac = invocation.getInvocationContext();

HttpServletRequest request = (HttpServletRequest) ac.get(ServletActionContext.HTTP_REQUEST);

HashMap map = request.getParameterMap();

Subject: Struts 2 file upload size validation

Hi,

we are trying to use file upload in Struts 2 and run into the following
problem.

We have a form with multiple fields among which one is a file input field.

The user must complete the form and then select a file to upload. If the
file size is larger than what we specify in the struts.properties the

FileUploadInterceptor validates and adds the error. Up to here everything is fine however upon having the error passed to the action we want to return to the same form, display the error and have the rest of fields populated with

the values the user has inputed (except the file field).

The problem is that when we get in the action (validate method) none of the

request parameters (form values) are populated. Everything is empty.

The question is why is this happening and how can we have the form values
populated in the action so that we can display the page correctly ?

Thanks
