I'm not sure exactly what you're trying to do. Or maybe I don't
understand your approach. I feel like I am missing SOMETHING.
That URL you're using, isn't a portal URL and so, HelloWorld will
probably be called as a standard servlet, outside the context of the
portal server. That is fine for displaying images or for referencing an
external resource, such as your SVG, but most certainly NOT OK if you're
trying to submit a form to, perform an action on, or request a refresh
of a portlet, as your reference to doView suggests. In my experience,
for a Portal URL (RenderURL or ActionURL), you can't just append "GET"
parameters to the URL as a string as you could with a traditional
servlet and expect it to work.
I suggest you obtain the JSR168 spec from here:
http://www.jcp.org/en/jsr/detail?id=168
Read the section on portal URLs and how to set parameters (PLT.7). I
think understanding the spec a little more will help you more in the
long-run than just fixing each problem as they arise.
As an alternative, you can always create a form with an actionURL and a
hidden input. Your SVG can set the value of the hidden input and submit
the form. THEN you'd be able to get the values, if not in doView
certainly in processAction.
