RE: PDF File Display in JSP-Struts
The question that Abhijeet asked was how to do it in a JSP. I agree that
doing this is a kludge.

Why would you ever do this? This looks like a complete and total kludge.
If you are sending back binary data (application/pdf), just do it from the
action class using the response.getOutputStream() and return null from the
execute method.
Advantages:
- you already have everything you need right there
- you eliminate the entry in struts-config
- you eliminate a useless jsp
- you can specify any content type (not just one per jsp)
- you get better exception handling
- the list could go on and on...

It may be an issue with using white space inside your jsp. I normally do
something like this (using a custom fo to pdf bean)... (note: everything up
to, and including, the c:set var=junkWhiteSpace is on one line)
%@ page contentType=application/pdf %%@ taglib prefix=c
uri=http://java.sun.com/jstl/core; %c:import var=blahFo
url=/test/blah.fo /c:set var=junkWhiteSpace
jsp:useBean id=foToPdf scope=page class=com...FoToPdf /
c:set target=${foToPdf} property=inputFo value=${blahFo} /
/c:setc:out value=${foToPdf.pdf} escapeXml=false /

Are you using the jsp writer, or the servlet output stream? JSP writer assumes char data and totally borks the pdf. SOS assumes binary data.

The better approach would be to set the proper mime type in the action itself...So that u dont put any restrictions on jsps then...And any how, if you are writing the pdf to output stream, why you still want to forward to a jsp?
