using Spring 2.0... and appfuse. One of the controllers is based on BaseFormController (it has an onSubmit and referenceData and a formBackingObject). Works just fine with the jsp.
I have an IFrame on the jsp, and the url is an attribute of the bean defined on the jsp and controller. The IFrame is inside the form tags. The url is a link to a PDF File. It appears to work on my development machine (the Tomcat is on the same box). If I try this from another machine, the whole app works except that the PDF becomes a Page Not Found. If I enter the url directly in the browser on the machine that's running Tomcat, I get the PDF. If I go through the page on another machine, the IFrame shows the Page Not Found, and the direct link is also Page Not Found.
