Hi, I've received a request to convert a currently existing mobile Struts/Tiles-based web application to serve content as MimeMultipart instead of XHTML. I wrote a ServletFilter that captures all markup in the response, then parses it to find all the necessary (css and img) files and downloads them. After that I create a MimeMultipart object, add markup as a parent part and styles and images as regular MimeBodyPart(s). Then I set contentType of the response object to be that of the MimeMultipart (ends up being "multipart/related; boundary xxxxxxx"), write MimeMultipart to it and close. I developed and tested on my local Tocat installation and everything worked as expected. When we attempted to deploy the code onto our QA server that is running Resin, we ran into a problem. The filter executes fine, body parts are added as expected and the contentType is set correctly to "multipart/related" (prints fine in the Logs). However, when it gets to the client, the contentType is overwritten to be "text/html; charset=UTF-8". As a result, browser tries to interpret the Mutlipart as regular markup writing out binary data for images, etc. - which is obviously not the desired result. At first I thought this could be due to the fact that our jsps/tiles explicitly and through directives set the contentType to be "text/html". So I captured the markup from a regular page in the app, added <%@ page language='java' session='true' contentType='text/html; charset=UTF-8'%> <% response.setContentType("text/html; charset=UTF-8"); %> to it and saved it as jsp page outside of WEB-INF so that I can hit it directly. This worked fine on Resin!!! I then created a fake Struts action mapping (ForwardAction) which forwarded to a fake Tiles definition - which pointed to the same exact test jsp page (that worked). In this scenario the problem resurfaced and contentType got overwritten to "text/html". I started blaming Struts. Struts has a way to set contentType on a per-module basis, through controller's contentType attribute. I decided to check if that was the root of my problem, so I've added <controller contentType="text/plain"/> to my struts configuration hoping to see my contentType being overwritten to be "text/plain" instead of "text/html". However, the contentType header still got overwritten to be text/html. Trying to think what can possibly be downstream from my filter I became suspicious of Apache. However, even after disabling mod_mime, the problem persisted!
At this point I don't know what to think and any help would be greatly appreciated! Thanks in advance!!! Misha.
