The standard (JSR-168) says that servlets and portlets can be bundled together in a portlet war. If WeSphere Portal does not allow this, it is WebSphere which is non-standard. I'd ask in their support lists for alternate ways to achieve this kind of functionality. In a portlet one cannot play with mime type or character set, as there are several portlets involved in the same page and the portal can decorate the page even for maximized portlets. One possibility would be to forward to a separate servlet container, where the download would take place, but it is a kludge, and I'm not sure that all requirements of A&A, session, etc. can be met easily.
