Trouble retrieving request parameters...

[Stewart Wachs <St...@trustvesta.com>]

I found some interesting behavior while trying to write a unit test for a
Taglib...

 

To retrieve request parameters from inside the Taglib I use
pageContext.getRequest().getParameter("foobar").

 

While this works when making requests from a web browser, it fails to
retrieve the request parameter that I setup

In my test fixture.

 

...

        request.setAttribute(PROGRAM, Constants.FOO_BAR);

        tag.setPageContext(this.pageContext);

 

        int result = tag.doStartTag();

 

        assertEquals(tag.SKIP_BODY, result);

        assertNull(pageContext.getSession().getAttribute(SHOPPING_CART));

        assertNull(pageContext.getSession().getAttribute(PRODUCT_LIST));

...

 

However, if I change my Taglib code to retrieve request parameters by using
pageContext.getAttribute("foobar", PageContext.REQUEST_SCOPE) the unit test
passes, but the web browser request fails. Any ideas of what's going on
here?

You've mismatched "attribute" and "parameter".  You probably intend to 
call getAttribute in that first line of code rather than getParameter.
