Tomcat include-prelude include-coda problem

[web4all]

HI
I am using <include-prelude> and <include-coda> in web.xml for my webapp
it works fine for html and jsp files but when it comes to PDF file it trys add <include-prelude> and <include-coda> to file wich result in an error.
Does any body knows how to disable/remove it for PDF files???
Here is part of web.xml:

<jsp-config>
<jsp-property-group>
<description>Login Folder</description>
<url-pattern>/folder1/folder2/*</url-pattern>
<include-prelude>/includes/prelude.jspf</include-prelude>
<include-coda>/includes/coda.jspf</include-coda>
</jsp-property-group>
</jsp-config>

Under folder2 i have subfolder with PDFs path /folder1/folder2/pdfs

thanks
